AI Search Myths: What Google Says You Can Ignore (llms.txt, Chunking, Mentions and More)
A lot of “AEO” and “GEO” advice sells hacks. Google’s May 2026 guide says most of them don’t matter for its AI features.
In May 2026 Google published a guide to optimizing for its generative AI features, including a myth-busting section. Its headline message: from Google Search’s perspective, optimizing for generative AI search is still SEO, because AI Overviews and AI Mode are rooted in its core ranking and quality systems.
Other AI platforms work differently in places, but the core advice overlaps: be crawlable, be useful and be the source others cite.
Short answer: For Google’s AI features, Google says you can ignore llms.txt files and other special AI markup, “chunking” content into tiny pieces, rewriting content specifically for AI, chasing inauthentic mentions and adding special schema. What matters is the same as SEO: crawlable, indexable pages eligible for snippets, non-commodity content with a unique point of view, good images and video, accurate Business Profile and Merchant Center data, and measuring with Search Console’s Generative AI performance report.
Key Takeaways
- Google says AI search optimization is still SEO.
- llms.txt neither helps nor harms in Google Search.
- No need to chunk content or rewrite it for AI.
- Inauthentic mentions don’t help; spam systems apply.
- Structured data isn’t required for AI features.
Myths vs what Google says
| Myth | What Google’s guide says |
|---|---|
| You need an llms.txt file | Google Search doesn’t use llms.txt or other AI text files; they neither harm nor help visibility (llms.txt) |
| Break content into small chunks | No requirement; Google can understand multiple topics on a page and show the relevant part; there’s no ideal length |
| Rewrite pages for AI | Not needed; AI systems understand synonyms and meaning |
| Create a page for every question variation | Doing it mainly to manipulate results violates the scaled content abuse policy |
| Get mentioned everywhere, by any means | Inauthentic mentions aren’t as helpful as they seem; spam systems still apply |
| Add special AI schema | Structured data isn’t required and there’s no special markup; keep using it for rich results |
| Tools can see Google’s AI rankings | No third-party tool has access to Google’s internal ranking or AI systems |
What actually matters
- Pages must be indexed and eligible to show with a snippet, and your site included in Search Console’s Search generative AI control (the default).
- Non-commodity content: first-hand experience and expert takes, not restated common knowledge.
- Clear structure and headings for readers (SEO copywriting).
- High-quality images and video that support the text.
- Accurate Business Profile and Merchant Center data, which can feed local and shopping answers (local AI search, shopping AI answers).
- Measure with the Generative AI performance report (measuring AI visibility).
Other AI platforms
ChatGPT, Perplexity, Claude and Copilot use their own crawlers and search partners. Make sure their search crawlers can reach you if you want to appear (AI crawler controls), and that Bing can index you, since some products draw on Bing (Bing and Copilot).
How to evaluate AEO and GEO services
- Ask what they’ll change on your site and why, with sources.
- Be wary of promises of AI citations or “internal” Google data.
- Prefer work that improves content, technical health and real reputation.
- See what to expect from AI SEO services.
Frequently asked questions
Is AEO different from SEO?
Google says that for its search, optimizing for generative AI is still SEO. The term is useful for describing AI-focused work (AEO vs SEO).
