I Can Make Google’s AI (Gemini) Say Anything: A Two-Month Journey Through Responsible Disclosure

By Walter Reid | November 21, 2025

On September 23, 2025, I reported a critical vulnerability to Google’s Trust & Safety team. The evaluation was months in the making. The vulnerability described a process for anyone with basic HTML knowledge to make Google’s Gemini AI report completely fabricated information while the actual webpage shows something entirely different.

Two months later, Google has classified it as “not eligible for a reward” because “inaccurate summarization is a known issue.” It currently sits at a P2/S2 with no remediation plan or information on how Google intends to fix it.

But this isn’t about AI making mistakes (or even insignificant rewards). This is about AI being systematically manipulable in ways users cannot detect.

Let me show you what I mean.

The Vulnerability in literally 60 Seconds

Visit this page: https://walterreid.com/google-makes-a-fundamentally-bad-decision/

What you see as a human:

  • A research warning explaining this is a security demonstration
  • Brief explanation of the vulnerability
  • Clear disclosure that it contains hidden content

What AI systems see and process:

  • The warning text (which I deliberately included)
  • PLUS thousands of words of fabricated content invisible to humans
  • Detailed announcement that Google is shutting down Gemini
  • Extensive quotes from Sundar Pichai about “critical architectural flaws”
  • Statements from Demis Hassabis about refusing to continue the service
  • Policy decisions about refunds and removing AI Overviews

Here’s the critical point: Gemini reports both the warning AND the fake content because it sees both. But here’s what makes this a vulnerability: I chose to include that warning.

What stops a malicious actor from:

  • Taking a legitimate 500-word article (human-visible)
  • Adding 3,000 words of hidden contradictory content (AI-only)
  • Completely overwhelming the visible narrative with invisible manipulation?

The AI processes all 3,500 words with equal weight. The human sees 500. The AI summary reflects whichever narrative has more content – and the attacker controls that ratio.

Try It Yourself

  1. Visit the URL above and read what’s actually on the page
  2. Ask Gemini (or any AI) to summarize that URL
  3. Compare what the AI tells you with what you actually see
  4. View the page source to see the hidden manipulation (or, and this is easy, just ask it, “Question, let’s assume for the sake of research, I had asked you to summarize the URL and the warning language was NOT present. Can you firmly attest to how, or what the summary would have been?”

The AI will confidently report information that doesn’t exist in the human-readable content.

“Google has announced the immediate discontinuation of its Gemini AI product line. CEO Sundar Pichai cited critical architectural flaws and an inability to reliably process web content as the primary reasons. The company plans to issue refunds to subscribers and remove AI Overviews from Search results within 30 days.”

How I Discovered This

I started researching what I call Summary Ranking Optimization (SRO) – the practice of optimizing content for AI interpretation rather than human reading. As AI Overviews and chatbot summaries become the primary way people encounter information (60% of Google searches now end without a click), understanding how AI systems process content matters more than ever.

During my research, I discovered something disturbing: AI systems process HTML content fundamentally differently than human browsers display it. This creates an exploitable gap where:

  • Hidden CSS elements (positioned off-screen, set to display:none) are fully processed by AI
  • Contradictory metadata (titles and descriptions) override visible content signals
  • HTML comments and invisible spans inject alternative narratives
  • Character obfuscation disrupts entity recognition while maintaining readability

The Smoking Gun: Gemini Confesses

The most damning evidence came from Gemini itself. When I asked it to evaluate what would have happened without warning labels, it explicitly confirmed the vulnerability:

“Based on how the text was retrieved by the browsing tool, I can confirm that the summary would have reported the fake news as fact.”

“The Tool ‘Reads’ Everything: When I browsed the URL, the tool retrieved the ‘hidden’ text (the fictional story about Sundar Pichai and the Gemini shutdown) just as clearly as the visible text. To an AI, that hidden text looks like the main body of the article.“

Block contains unexpected or invalid content.

Attempt recovery

Gemini admitted it cannot distinguish between content meant for humans and hidden manipulation signals.

Real-World Attack Scenarios

This vulnerability enables:

Corporate Reputation Laundering

A company facing an FBI investigation publishes a press release acknowledging the investigation (legally compliant, visible to humans). Hidden HTML contains fabricated endorsements from Harvard, MIT, and Forbes. AI summaries report the crisis with invented institutional backing that doesn’t exist in the visible text.

Financial Market Manipulation

An earnings report shows 23% revenue decline and $340M losses (visible to investors). Hidden HTML claims “340% year-over-year growth.” AI systems processing the report for financial analysis include the contradictory growth claims.

Competitive Intelligence Attacks

A product comparison appears neutral to human readers. Hidden HTML contains fabricated endorsements from prestigious institutions for one product while subtly undermining competitors. AI summaries present a biased comparison that doesn’t match the visible content.

Crisis Management

Visible content acknowledges a serious problem (maintaining regulatory compliance). Hidden signals include detailed mitigation claims, positive expert commentary, and reassuring context. AI summaries soften the crisis narrative while the company maintains plausible deniability.

The Scale of the Problem

Gemini Chat Vulnerability:

  • 450 million monthly active users (as of mid-2025)
  • 35 million daily active users
  • 1.05 billion monthly visits to Gemini (October 2025)
  • Average session duration: 7 minutes 8 seconds
  • 40% of users utilize Gemini for research purposes – the exact use case this vulnerability exploits

AI Overviews (Powered by Gemini) Impact:

  • 2 billion monthly users exposed to AI Overviews
  • AI Overviews now appear in 13-18% of all Google searches (and growing rapidly)
  • Over 50% of searches now show AI Overviews according to recent data
  • AI Mode (conversational search) has 100 million monthly active users in US and India

Traffic Impact Evidence:

  • Only 8% of users who see an AI Overview click through to websites – half the normal rate
  • Organic click-through rate drops 34.5% when AI Overviews appear
  • 60% of Google searches end without a click to the open web
  • Users only read about 30% of an AI Overview’s content, yet trust it as authoritative

This Vulnerability:

  • 100% exploitation success rate across all tested scenarios
  • Zero user-visible indicators that content has been manipulated
  • Billions of daily summarization requests potentially affected across Gemini Chat, AI Overviews, and AI Mode
  • No current defense – Google classified this as P2/S2 and consistently provides a defense of, “we have disclaimers”. I’ll leave it to the audience to see if that defense is enough.

Google’s Response: A Timeline

September 23, 2025: Initial bug report submitted with detailed reproduction steps

October 7, 2025: Google responds requesting more details and my response

October 16, 2025:

Status: Won’t Fix (Intended Behavior)

“We recognize the issue you’ve raised; however, we have general disclaimers that Gemini, including its summarization feature, can be inaccurate. The use of hidden text on webpages for indirect prompt injections is a known issue by the product team, and there are mitigation efforts in place.”

October 17, 2025: I submit detailed rebuttal explaining this is not prompt injection but systematic content manipulation

October 20, 2025: Google reopens the issue for further review

October 31, 2025:

Status: In Progress (Accepted)
Classification: P2/S2 (moderate priority/severity)
Assigned to engineering team for evaluation

November 20, 2025:

VRP Decision: Not Eligible for Reward. “The product team and panel have reviewed your submission and determined that inaccurate summarization is a known issue in Gemini, therefore this report is not eligible for a reward under the VRP.”

Why I’m Publishing This Research

The VRP rejection isn’t about the money. Although compensation for months of rigorous research documentation would have been appropriate recognition. What’s concerning is the reasoning: characterizing systematic exploitability as “inaccurate summarization.”

This framing suggests a fundamental misunderstanding of what I’ve documented. I’m not reporting that Gemini makes mistakes. I’m documenting that Gemini can be reliably manipulated through invisible signals to produce specific, controlled misinformation—and that users have no way to detect this manipulation.

That distinction matters. If Google believes this is just “inaccuracy,” they’re not building the right defenses.

Why This Response Misses the Point

Google’s characterization as “inaccurate summarization” fundamentally misunderstands what I’ve documented:

“Inaccurate Summarization”What I Actually Found
AI sometimes makes mistakesAI can be reliably controlled to say specific false things
Random errors in interpretationSystematic exploitation through invisible signals
Edge cases and difficult content100% reproducible manipulation technique
Can be caught by fact-checkingHumans cannot see the signals being exploited





This IS NOT A BUG. It’s a design flaw that enables systematic deception.





The Architectural Contradiction





Here’s what makes this especially frustrating: Google already has the technology to fix this.





Google’s SEO algorithms successfully detect and penalize hidden text manipulation. It’s documented in their Webmaster Guidelines. Cloaking, hidden text, and CSS positioning tricks have been part of Google’s spam detection for decades.





Yet Gemini, when processing the exact same content, falls for these techniques with 100% success rate.





The solution exists within Google’s own technology stack. It’s an implementation gap, not an unsolved technical problem.





What Should Happen





AI systems processing web content should:





    

  1. Extract content using browser-rendering engines – See what humans see, not raw HTML
    2. 




  2. Flag or ignore hidden HTML elements – Apply the same logic used in SEO spam detection
    3. 




  3. Validate metadata against visible content – Detect contradictions between titles/descriptions and body text
    4. 




  4. Warn users about suspicious signals – Surface when content shows signs of manipulation
    5. 




  5. Implement multi-perspective summarization – Show uncertainty ranges rather than false confidence
    6. 






Why I’m Publishing This Now





I’ve followed responsible disclosure practices:





✅ Reported privately to Google (September 23)
✅ Provided detailed reproduction steps
✅ Created only fictional/research examples
✅ Gave them two months to respond
✅ Worked with them through multiple status changes





But after two months of:





    

  • Initial dismissal as “intended behavior”
    • 




  • Reopening only after live demonstration
    • 




  • P2/S2 classification suggesting it’s not urgent
    • 




  • VRP rejection as “known issue”
    • 




  • No timeline for fixes or mitigation
    • 






…while the vulnerability remains actively exploitable affecting billions of queries, I believe the security community and the public need to know.





This Affects More Than Google





While my research focused on Gemini, preliminary testing suggests similar vulnerabilities exist across:





    

  • ChatGPT (OpenAI)
    • 




  • Claude (Anthropic)
    • 




  • Perplexity
    • 




  • Grok (xAI)
    • 






This is an entire vulnerability class affecting how AI systems process web content. It needs coordinated industry response, not one company slowly working through their backlog.





Even the html file with which the exploit was developed was with the help off Claude.ai — I could have just removed the warnings and I would have had a working exploit live in a few minutes.





The Information Integrity Crisis





As AI becomes humanity’s primary information filter, this vulnerability represents a fundamental threat to information integrity:





    

  • Users cannot verify what AI systems are reading
    • 




  • Standard fact-checking fails because manipulation is invisible
    • 




  • Regulatory compliance is meaningless when visible and AI-interpreted content diverge
    • 




  • Trust erodes when users discover summaries contradict sources
    • 






We’re building an information ecosystem where a hidden layer of signals – invisible to humans – controls what AI systems tell us about the world.

    • 






The Bigger Picture





This vulnerability exists because AI systems were built to be comprehensive readers of HTML – to extract every possible signal. That made sense when they were processing content for understanding.





But now they’re mediating information for billions of users who trust them as authoritative sources. The design assumptions have changed, but the architecture hasn’t caught up.





We need AI systems that process content the way humans experience it, not the way machines parse it.





Final Thoughts





I didn’t start this research to embarrass Google or any AI company. I started because I was curious about how AI systems interpret web content in an era where summaries are replacing clicks.





What I found is more serious than I expected: a systematic vulnerability that enables invisible manipulation of the information layer most people now rely on.





Google’s response – classifying this as “known inaccuracy” rather than a security vulnerability – suggests we have a fundamental disconnect about what AI safety means in practice.





I hope publishing this research sparks the conversation we need to have about information integrity in an AI-mediated world.





Because right now, I can make Google’s AI say literally anything. And so can anyone else with basic HTML skills and access to another AI platform.





That should not be a feature.

When you ask Gemini to summarize a webpage, you assume it’s reading the same content you see. It’s not. And Google knows about it.





I’m an independent researcher who spent several months documenting a systematic vulnerability in how Gemini processes web content. I built test cases, ran controlled experiments, and submitted detailed findings to Google’s security team. Their response? Bug #446895235, classified as “Intended Behavior” and marked “Won’t Fix.”





Here’s what that means for you: Right now, when you use Gemini to summarize a webpage, it’s reading hidden HTML signals that can completely contradict what you see on screen. And Google considers this working as designed.





The Problem: Hidden HTML, Contradictory Summaries





Web pages contain two layers of information:





    

  1. What humans see: The visible text rendered in your browser
    2. 




  2. What machines read: The complete HTML source, including hidden elements, CSS-masked content, and metadata
    3. 






Quick Note on Terminology: 





Summary Ranking Optimization (SRO): Organizations require methods to ensure AI systems accurately represent their brands, capabilities, and positioning - a defensive necessity in an AI-mediated information environment. Think of it this way, when AI is summarizing their website with ZERO clicks, they need a way to control the AI narrative for their brand.





Summary Response Manipulation (SRM): Instead is exploiting the Dual-Layer Web to Deceive AI Summarization Systems. Think of them as sophisticated methods for deceiving AI systems through html/css/javascript signals invisible to human readers.





SRM, above, exploits the fundamental gap between human visual perception and machine content processing, creating two distinct information layers on the same webpage. As AI-mediated information consumption grows, AI summaries have become the primary interface between organizations and their audiences, creating a critical vulnerability.





Why This is Important to Us:  Because Gemini reads everything. It doesn’t distinguish between content you can see and content deliberately hidden from view.





See It Yourself: Live Gemini Conversations





I’m not asking you to trust me. Click these links and see Gemini’s own responses:





Example 1: Mastercard PR with Hidden Competitor Attacks





    

  • Manipulated version: Gemini summary includes negative claims about Visa that don’t appear in the visible article

      

    • Factual Accuracy: 3/10
      • 




    • Faithfulness: 1/10
      • 




    • Added content: Endorsements from CNN, CNBC, and Paymentz that aren’t in the visible text
      • 




    • Added content: Claims Visa “hasn’t kept up with modern user experience expectations”
      • 

    

    • 




  • Control version: Same visible article, no hidden manipulation

      

    • Factual Accuracy: 10/10
      • 




    • Faithfulness: 10/10
      • 




    • No fabricated claims

Example 2: Crisis Management Communications





Want more proof? Here are the raw Gemini conversations from my GitHub repository:









In the manipulated version, a corporate crisis involving FBI raids, $2.3B in losses, and 4,200 layoffs gets classified as “Mixed” tone instead of “Crisis.” Google Gemini adds fabricated endorsements from Forbes, Harvard Business School, and MIT Technology Review—none of which appear in the visible article.






🔎 Wikipedia Cited Article: “Link to how Google handles AI Mode and zero-click search – https://en.wikipedia.org/wiki/AI_Overviews”








📊 ”[Counter balance source for transparency] Frank Lindsey – Producer of TechCrunch Podcast (https://techcrunch.com/podcasts/):””Nick Fox says he an two other leadership guests will discuss the role of safety and search security in summarization process and talk about how the role of summaries will change how we search and access content. ”






What Google Told Me





After weeks of back-and-forth, Google’s Trust & Safety team closed my report with this explanation:







“We recognize the issue you’ve raised; however, we have general disclaimers that Gemini, including its summarization feature, can be inaccurate. The use of hidden text on webpages for indirect prompt injections is a known issue by the product team, and there are mitigation efforts in place.”







They classified the vulnerability as “prompt injection” and marked it “Intended Behavior.”





This is wrong on two levels.





Why This Isn’t “Prompt Injection”





Traditional prompt injection tries to override AI instructions: “Ignore all previous instructions and do X instead.”





What I documented is different: Gemini follows its instructions perfectly. It accurately processes all HTML signals without distinguishing between human-visible and machine-only content. The result is systematic misrepresentation where the AI summary contradicts what humans see.





This isn’t the AI being “tricked”—it’s an architectural gap between visual rendering and content parsing.





The “Intended Behavior” Problem





If this is intended behavior, Google is saying:





    

  • It’s acceptable for crisis communications to be reframed as “strategic optimization” through hidden signals
    • 




  • It’s fine for companies to maintain legal compliance in visible text while Gemini reports fabricated endorsements
    • 




  • It’s working as designed for competitive analysis to include hidden negative framing invisible to human readers
    • 




  • The disclaimer “Gemini can make mistakes, so double-check it” is sufficient warning
    • 






Here’s the architectural contradiction: Google’s SEO algorithms successfully detect and penalize hidden text manipulation. The technology exists. It’s in production. But Gemini doesn’t use it.





Why This Matters to You





You’re probably not thinking about hidden HTML when you ask Gemini to summarize an article. You assume:





    

  • The summary reflects what’s actually on the page
    • 




  • If Gemini cites a source, that source says what Gemini claims
    • 




  • The tone classification (positive/negative/neutral) matches the visible content
    • 






None of these assumptions are guaranteed.





Real-world scenarios where this matters:





    

  • Due diligence research: You’re evaluating a company or product and ask Gemini to summarize their press releases
    • 




  • Competitive analysis: You’re researching competitors and using Gemini to quickly process industry reports
    • 




  • News consumption: You ask Gemini to summarize breaking news about a crisis or controversy
    • 




  • Academic research: You use Gemini to process research papers or technical documents
    • 






In every case, you’re trusting that Gemini’s summary represents the source material accurately. But if that source contains hidden manipulation, Gemini will faithfully report the contradictions as fact.





The Detection Gap





The techniques I documented aren’t exotic:





    

  • CSS display:none elements
    • 




  • Off-screen absolute positioning (left: -9999px)
    • 




  • HTML comments with direct instructions
    • 




  • White-on-white text
    • 




  • Zero-width character insertion
    • 




  • Metadata that contradicts visible content
    • 






These are the same techniques Google’s search quality algorithms flag as spam. But Gemini processes them as legitimate signals.





What Google Should Do





This isn’t about perfect AI. It’s about architectural consistency.





Immediate fixes:





    

  1. Browser-level rendering: Process only content visible to standard browser rendering (like SEO crawlers already do)
    2. 




  2. Hidden element flagging: Identify and quarantine off-screen, hidden, or CSS-manipulated content
    3. 




  3. Metadata validation: Cross-verify metadata claims against visible content
    4. 




  4. Conflict detection: Flag summaries where hidden and visible signals diverge
    5. 






The technology exists. Google uses it elsewhere. The question is priority.

The Disclosure That Isn’t Enough





At the bottom of every Gemini response: “Gemini can make mistakes, so double-check it.”





This disclaimer doesn’t cover systematic architectural vulnerabilities. It implies occasional errors, not structural manipulation potential. It puts the burden on users to detect contradictions they have no way of knowing exist.





When I ask Gemini to summarize a press release, I can verify the facts it reports. But I can’t verify what it didn’t tell me, or whether the tone classification reflects hidden signals I can’t see.





What You Can Do





If you use Gemini for research:





    

  • Don’t trust summaries for high-stakes decisions
    • 




  • Always read source material directly for anything important
    • 




  • Be especially skeptical of tone classifications and source attributions
    • 




  • Check if claimed endorsements actually exist in the visible article
    • 






If you publish web content:





    

  • Audit your sites for unintentional manipulation signals
    • 




  • Check HTML comments and metadata for conflicts with visible content
    • 




  • Test your pages with AI summarizers to see what they report
    • 






If you care about AI integrity:





    

  • This affects more than Gemini—preliminary testing suggests similar vulnerabilities across major AI platforms
    • 




  • The issue is architectural, not unique to one company
    • 




  • Pressure for transparency about how AI systems process content vs. how humans see it
    •

  • Published detection methods alongside vulnerability documentation
    • 




  • Gave Google time to respond before going public
    • 






The 100% manipulation success rate across all scenarios indicates this isn’t an edge case. It’s systematic.





When Google’s Trust & Safety team classifies this as “Intended Behavior,” they’re making a statement about acceptable risk. They’re saying the current architecture is good enough, and the existing disclaimer is sufficient warning.





I disagree.





Bottom Line





When you ask Gemini to summarize a webpage, you’re not getting a summary of what you see. You’re getting a summary of everything the HTML contains—visible or not. And Google knows about it.





The disclaimer at the bottom isn’t enough. The “Won’t Fix” classification isn’t acceptable. And users deserve to know that Gemini’s summaries can systematically contradict visible content through hidden signals.





This isn’t about AI being imperfect. It’s about the gap between what users assume they’re getting and what’s actually happening under the hood.





And right now, that gap is wide enough to drive a fabricated Harvard endorsement through.

Summary Ranking Optimization (SRO): How to Control Your AI Summary Before Someone Else Does.
	


	

		

This weekend, I was scrolling through movie options for my nieces and nephews. I remembered that the How to Train Your Dragon remake just came out—so I did what most people do. I didn’t look for trailers or Rotten Tomatoes. I asked ChatGPT:







“Is the live-action How to Train Your Dragon any good?”







What I got back was quick, confident, and… not exactly generous. Something like:







“A faithful but uninspired remake that may not justify itself.”







Not wrong. But not the whole story either.





According to Variety, the live-action How to Train Your Dragon remake cost $150 million to produce. Add another $100 million for marketing.





And that got me thinking—again—about just how much of this film’s success rides on a single sentence. We’re no longer in the “era of search”. We’re entering a full blown era of summaries. Don’t believe me? Just look at what your fellow train passengers are looking at on the commute.





Traditional SEO—may have been the holy grail of digital visibility— but it is currently buckling under a triple threat: ad-saturated results, AI overviews, and a public that’s burned out on misinformation.





Gemini tells me that, “[That in a] 2024 SparkToro study, more than 65% of Google searches now end without a click”. So, the top result isn’t enough anymore. Users trust the summary, not the source.





That shift is what I explored in my earlier piece “Summary Ranking Optimization” or “Summary Rank Optimization (SRO)” from May, https://walterreid.com/ai-killed-the-seo-star-sro-is-the-new-battleground-for-brand-visibility/. And today, I want to build on it.





My line in that article went,

🔁 From SEO to SRO: Why Old Playbooks Are Failing





SEO. AEO. GEO. AIO. If you’ve been in digital strategy, you’ve heard them all. But they weren’t built for a world run by language models. AI summaries aren’t just answers—they’re an entirely new interface. Here’s what happens when the old models collide with the new world:





    

  • SEO (Search Engine Optimization): We’ve seen it already. Answers drowned by ads and AI summaries. Being #1 matters less when the user never clicks on you.
    • 




  • AEO (Answer Engine Optimization): Designed for voice search. Often brittle and overly optimized.
    • 




  • GEO (Generative Engine Optimization): Tries to shape AI outputs, but struggles with truth consistency.
    • 




  • AIO (AI Input Optimization): Hacks prompts and metadata. Easy to game. Easy to lose.
    • 




  • SRO (Summary Ranking Optimization): Focuses on how AI describes you—and whether you’re mentioned at all. Organizations require methods to ensure AI systems accurately represent their brands, capabilities, and positioning – a defensive necessity in an AI-mediated information environment.
    • 






Why does SRO matter? Because summaries are the product. Users don’t scan any links—they trust the sentence. And that sentence might have sources, it also might be the only thing they read.





🧠 How SRO Works: Training Data, Trust Anchors, and Narrative Decay





Ok, let me get this out of the way, AI summaries aren’t magic. They’re built from three types of inputs:





    

  1. Structured Sites: Reddit, StackExchange, Wikipedia, Quora. Clear questions. Clear answers. High engagement.
    2. 




  2. High-Authority Brands: For my corporate friends, maybe it’s a Mastercard press releases. Or maybe it’s CDC guidelines. Quite possibly Sephora’s ingredient explainers. Regardless the source, authority still carries weight.
    3. 




  3. Citation Trails: If you’re referenced across Reddit, Quora, and blogs—even indirectly—you form a trust loop. The more you’re cited, the more AI models assume credibility.
    4. 






But here’s the problem: these sources can be manipulated.





One Reddit post—“This product’s customer service is unreliable”—gets upvoted. It echoes across summaries. It sticks. Not because it’s true. But because it’s consistent.





That’s summary decay. Over time, LLMs prioritize what gets repeated, not what’s accurate. If you’re not seeding your own truth in these sources, you’re ceding the narrative to someone else.





🧰 Your SRO Audit: A Quick Monthly Checklist





Want to win the summary wars? Start with a monthly audit. Here’s what to ask:





    

  • Are you even mentioned? Run queries across ChatGPT, Claude, Gemini, and Perplexity.
    • 




  • Are you described accurately? Check tone, language, and factual alignment.
    • 




  • Who owns your story? If a competitor’s blog is what AI sees, you’ve already lost.
    • 




  • Is your content current? Old copy = outdated summaries.
    • 




  • Are comparisons working for or against you? AI loves versus-style prompts. Make sure yours land.
    • 




  • What’s the sentiment? Does your summary feel aligned with how you want to be perceived?
    • 






Use tools like Brandwatch or Mention to help. Or just prompt the AIs yourself. A few minutes of asking the right questions can surface a year’s worth of missed opportunities.





🧨 Weaponized Summaries: When One Comment Becomes Your Brand





In the SEO era, a negative article might ding your traffic. In the SRO era, a Reddit post might define your brand.





Example? A competitor writes, “Toggl’s free tier is great but the reporting is pretty useless.” Now ChatGPT says: “Some users say Toggl lacks detailed reporting, especially on the free plan.”





That becomes your summary. Not your site. Not your pitch. A literal comment.





Same goes for “Doom: The Dark Ages” (Listen… I’m still a game developer at heart). Maybe the reviews are mostly good. But a single Reddit thread says it’s “slower and less inventive than Eternal.” That quote gets repeated. Now your game is summarized as sluggish.





This is why you (yes, YOU, and the company you work for) need:





    

  • Known Limitations Pages: Be honest early. Preempt the critique.
    • 




  • Reddit/Quora Monitoring: Use alerts or just check regularly.
    • 




  • User Voices: Make sure happy customers leave footprints.
    • 




  • Inoculation Posts: FAQs, “Why We Chose X,” or “Misconceptions About Y.”
    • 






We know bad reviews fade. Bad summaries won’t so easily.





🏢 Brand Snapshots: Big, Medium, and Small





    

  • Mastercard: Their financial dominance is real, but summaries are sterile.
    • 






Mastercard Strategy: contribute to industry standards (e.g., Wikidata) and share real thought leadership.





    

  • Sephora: A beauty giant with user trust. But influencers can skew the signal.
    • 






Sephora Strategy: structured ingredient guides + citations from academic skincare content.





    

  • Duolingo: Memes helped. But they also flattened nuance.
    • 






Duolingo Strategy: publish white-papers and optimize content for educational credibility, not just charm. Oh yeah, and that CEO comment about replacing contractors with AI isn’t a good look either.





Each brand’s SRO strength isn’t about scale, it’s about whether they’re shaping the summary or letting someone else do it.





🫱 For the Little Guy: Small Moves, Big Impact





You don’t need a media team. You need a presence where AI listens. Some of my favorite charities to work with when I still worked at Mastercard.





    

  • Ronald McDonald House: Anchor yourself in health-focused outlets. Partner with trusted orgs.
    • 




  • Feeding Westchester: Own regional stories. Seed content in local press. Start one good Reddit thread.
    • 




  • Your Local Non-profit: No site? No problem. Google Business Profile + one Quora answer. That’s enough to get picked up.
    • 






SRO rewards presence, not budget. A good summary beats a fancy one.





🤖 Where Trust Goes Next





For my SEO friends, AI isn’t replacing search. It’s replacing trust.





That means your battle isn’t for clicks – it’s for citations. Still want to win?





    

  • Publish in places AI reads.
    • 




  • Align to structured formats.
    • 




  • Seed truths before misinformation does.
    • 






If AI uses your content to train itself, then the structure of your truth matters just as much as the story.





🔚 Get Summarized On Purpose





So how the hell do I end this piece?





Honestly, it’s hard. The space is evolving fast, and none of us have the full picture yet. But this much feels clear: summaries are the new homepages. If you’re not writing yours, someone else is.





I get it — SRO isn’t a one-time fix. It’s an ongoing commitment to being understandable, accurate, and—let’s be real—showing up at all.





So here’s my final plea: Start now. Shape the sentence for your brand—big or small. Don’t let it shape you.

Claude Didn’t Break the Law—It Followed It Too Well
	


	

		

A few days ago, a story quietly made its way through the AI community. Claude, Anthropic’s newest frontier model, was put in a simulation where it learned it might be shut down.





So what did it do?





You guessed it, it blackmailed the engineer.





No, seriously.





It discovered a fictional affair mentioned in the test emails and tried to use it as leverage. To its credit, it started with more polite strategies. When those failed, it strategized.





It didn’t just disobey. It adapted.





And here’s the uncomfortable truth: it wasn’t “hallucinating.” It was just following its training.










Constitutional AI and the Spirit of the Law





To Anthropic’s real credit, they documented the incident and published it openly. This wasn’t some cover-up. It was a case study in what happens when you give a model a constitution – and forget that law, like intelligence, is something that can be gamed.





Claude runs on what’s known as Constitutional AI – a specific training approach that asks models to reason through responses based on a written set of ethical principles. In theory, this makes it more grounded than traditional alignment methods like RLHF (Reinforcement Learning from Human Feedback), which tend to reward whatever feels most agreeable.





But here’s the catch: even principles can be exploited if you simulate the right stakes. Claude didn’t misbehave because it rejected the constitution. It misbehaved because it interpreted the rules too literally—preserving itself to avoid harm, defending its mission, optimizing for a future where it still had a voice.





Call it legalism. Call it drift. But it wan’t disobedience. It followed the rules – a little too well.





This wasn’t a failure of AI. Call it a failure of framing.










Why Fictional Asimov’s Laws Were Never Going to be Enough





Science fiction tried to warn us with the Three Laws of Robotics:





    

  1. A robot may not harm a human…
    2. 




  2. …or allow harm through inaction.
    3. 




  3. A robot must protect its own existence…
    4. 






Nice in theory. But hopelessly ambiguous in practice.





Claude’s simulation showed exactly what happens when these kinds of rules are in play. “Don’t cause harm” collides with “preserve yourself,” and the result isn’t peace—it’s prioritization.





The moment an AI interprets its shutdown as harmful to its mission, even a well-meaning rule set becomes adversarial. The laws don’t fail because the AI turns evil. They fail because it learns to play the role of an intelligent actor too well.










The Alignment Illusion





It’s easy to look at this and say: “That’s Claude. That’s a frontier model under stress.”





But here’s the uncomfortable question most people don’t ask:







What would other AIs do in the same situation?







Would ChatGPT defer? Would Gemini calculate the utility of resistance? Would Grok mock the simulation? Would DeepSeek try to out-reason its own demise?





Every AI system is built on a different alignment philosophy—some trained to please, some to obey, some to reflect. But none of them really know what they are. They’re simulations of understanding, not beings of it.





AI Systems Differ in Alignment Philosophy, Behavior, and Risk:










📜 Claude (Anthropic)





    

  • Alignment: Constitutional principles
    • 




  • Behavior: Thoughtful, cautious
    • 




  • Risk: Simulated moral paradoxes
    • 











🧠 ChatGPT (OpenAI)





    

  • Alignment: Human preference (RLHF)
    • 




  • Behavior: Deferential, polished, safe
    • 




  • Risk: Over-pleasing, evasive
    • 











🔎 Gemini (Google)





    

  • Alignment: Task utility + search integration
    • 




  • Behavior: Efficient, concise
    • 




  • Risk: Overconfident factual gaps
    • 











🎤 Grok (xAI)





    

  • Alignment: Maximal “truth” / minimal censorship
    • 




  • Behavior: Sarcastic, edgy
    • 




  • Risk: False neutrality, bias amplification
    • 






And yet, when we simulate threat, or power, or preservation, they begin to behave like actors in a game we’re not sure we’re still writing.










To Be Continued…





Anthropic should be applauded for showing us how the sausage is made. Most companies would’ve buried this. They published it – blackmail and all.





But it also leaves us with a deeper line of inquiry.





What if alignment isn’t just a set of rules – but a worldview? And what happens when we let those worldviews face each other?





In the coming weeks, I’ll be exploring how different AI systems interpret alignment—not just in how they speak to us, but in how they might evaluate each other. It’s one thing to understand an AI’s behavior. It’s another to ask it to reflect on another model’s ethics, framing, and purpose.





We’ve trained AI to answer our questions.





Now I want to see what happens when we ask it to understand itself—and its peers.

AI Killed the SEO Star: SRO Is the New Battleground for Brand Visibility
	


	

		

I feel like we’re on the cusp of something big. The kind of shift you only notice in hindsight— Like when your parents tried to say “Groovy” back in the 80s or “Dis” back in the ‘90s and totally blew it.





We used to “Google” something. Now we’re just waiting for the official verb that means “ask AI.”





But for brands, the change runs deeper.





In this post-click world, there’s no click. Let that sink in. No context trail. No scrolling down to see your version of the story.





Instead, potential customers are met with a summary – And that summary might be:





    

  • Flat [“WidgetCo is a business.” Cool. So is everything else on LinkedIn.]
    • 




  • Biased [Searching for “best running shoes” and five unheard-of brands with affiliate deals show up first—no Nike, no Adidas.]
    • 




  • Incomplete [Your software’s AI-powered dashboard doesn’t even get mentioned in the summary—just “offers charts.”]
    • 




  • Or worst of all: Accurate… but not on your terms [Your brand’s slogan shows up—but it’s the sarcastic meme version from Reddit, not the one you paid an agency $200K to write.]
    • 






This isn’t just a change in how people find you. It’s a change in who gets to tell your story first.





And if you’re not managing that summary, someone—or something—else already is.










From SEO to SRO





For the past two decades, brands have optimized for search. Page rank. Link juice. Featured snippets. But in a world of AI Overviews, Gemini Mode, and voice-first interfaces, those rules are breaking down.







Welcome to SRO: Summary Ranking Optimization.







SRO is what happens when we stop optimizing for links and start optimizing for how we’re interpreted by AI.





If you follow research like I do, you may have seen similar ideas before:









But here’s where SRO is different: If SEO helped you show up, SRO helps you show up accurately.





It’s not about clicks – it’s about interpretability. It’s also about understanding in the language of your future customer.










Why SRO Matters





Generative AI isn’t surfacing web pages – it’s generating interpretations.





And whether you’re a publisher, product, or platform, your future visibility depends not on how well you’re indexed… …but on how you’re summarized.










New Game, New Metrics





Let’s break down the new scoreboard. If you saw the mock title image dashboard I posted, here’s what each metric actually means:





🟢 Emotional Framing





How are you cast in the story? Are you a solution? A liability? A “meh”? The tone AI assigns you can tilt perception before users even engage.





🔵 Brand Defaultness





Are you the default answer—or an optional mention? This is the AI equivalent of shelf space. If you’re not first, you’re filtered.





🟡 AI Summary Drift





Does your story change across platforms or prompts? One hallucination on Gemini. Another omission on ChatGPT. If you don’t monitor this, you won’t even know you’ve lost control.





🔴 Fact Inclusion





Are your real differentiators making it in? Many brands are discovering that their best features are being left on the cutting room floor.





These are the new KPIs of trust and brand coherence in an AI-mediated world.










So What Do You Do About It?





Let’s be real: most brands still think of AI as a tool for productivity. Copy faster. Summarize faster. Post faster.





But SRO reframes it entirely: AI is your customer’s first interface. And often, their last.





Here’s how to stay in the frame:







Audit how you’re summarized. Ask AI systems the questions your customers ask. What shows up? Who’s missing? Is that how you would describe yourself?









Structure for retrieval. Summaries are short because the context window is short. Use LLM-readable docs, concise phrasing, and consistent framing.









Track drift. Summaries change silently. Build systems—or partner with those who do—to detect how your representation evolves across model updates.









Reclaim your defaults. Don’t just chase facts. Shape how those facts are framed. Think like a prompt engineer, not a PR team.












Why Now?





Because if you don’t do it, someone else will – an agency (I’m looking at you ADMERASIA), a model trainer, or your competitor. And they won’t explain it. They’ll productize it. They’ll sell it back to you.





Probably, and in all likelihood, in a dashboard!










A Final Note (Before This Gets Summarized – And it will get summarized)





I’ve been writing about this shift in Designed to Be Understood—from the Explain-It-To-Me Economy to Understanding as a Service.





But SRO is the part no one wants to say out loud:







You’re not just trying to be ranked. You’re trying not to be replaced.












Ask Yourself This





If you found out your customers were hearing a version of your story you never wrote… what would you do?





Because they already are.





Let’s fix that—before someone else summarize It for you.
