Quick Answer
In May 2026, Google published its first official Google AI search guide: a documentation page called Optimizing your website for generative AI features on Google Search (Google, 2026). On June 5, 2026, Google expanded it alongside new guidance on third-party SEO services. For the first time, Google names AEO and GEO in official documentation, states that optimizing for generative AI search is still SEO, and lists the tactics you can safely ignore: llms.txt files, content chunking, AI-specific rewriting, and paid mention schemes.
What Is the Google AI Search Guide?
The Google AI search guide is an official Search Central documentation page that explains how to optimize for AI Overviews and AI Mode. It expands the earlier AI features documentation Google published in 2025, and it is the first place where Google addresses the AEO and GEO debate in writing.
The timeline matters. Search Engine Journal covered the guide on May 15, 2026 (SEJ, 2026). Google then updated it on June 5, 2026, together with a brand new page on evaluating third-party SEO tools, services, and advice (Google, 2026). In the same week, Search Console began rolling out generative AI performance reports to a first group of UK properties.
Put together, the Google AI search guide is not a casual blog post. It is Google consolidating positions that were previously scattered across conference talks and podcasts into citable, official documentation.
Why Is This a Big Deal for GEO and AEO?
Because the Google AI search guide did two things at once: it legitimized the category and drew a hard line against the hacks sold under its name.
The guide defines AEO as answer engine optimization and GEO as generative engine optimization, then states: “From Google Search’s perspective, optimizing for generative AI search is optimizing for the search experience, and thus still SEO.” That sentence ends a two-year terminology war, at least for Google’s own AI features.
Our reading at Visifly: being named in official Google documentation is the strongest signal yet that AI visibility work is a real discipline. At the same time, the Google AI search guide makes the cost of bad advice visible. If a vendor is selling you magic AI files or special schema, Google now says, in writing, that you are paying for nothing.
What Does the Google AI Search Guide Tell You to Ignore?
The mythbusting section is the heart of the document. Here is every tactic Google names, its verdict, and what to do instead:
| Tactic | Google verdict | What to do instead |
|---|---|---|
| llms.txt and special AI files | Not needed for generative AI search | Keep content crawlable and indexable as normal HTML |
| Chunking content into tiny pieces | No requirement; systems understand full pages | Structure pages for human readers with clear headings |
| Rewriting content just for AI | Unnecessary; AI understands synonyms and meaning | Write naturally for your audience |
| Buying inauthentic mentions | Spam systems block it; not as helpful as it seems | Earn real citations through useful content |
| Special AI schema markup | No special schema exists for AI features | Keep standard structured data for rich results |
One honest nuance: this verdict applies to Google. ChatGPT, Perplexity, and other answer engines run their own retrieval systems and may read signals Google ignores. An llms.txt file costs nothing to keep. The mistake is paying someone to create one as a “GEO service” – and that is exactly the practice Google is warning against.
What Does Google Want You to Do Instead?
The Google AI search guide explains the mechanics behind AI Overviews and AI Mode. Two concepts matter: retrieval-augmented generation (RAG), where AI answers are grounded in pages retrieved from the core Search index, and query fan-out, where the model issues related queries to gather more sources. The practical consequence: if your pages are not indexed and snippet-eligible, you are not in the pool AI answers draw from.
On content, Google pushes one idea hard: non-commodity content. A generic listicle like “7 Tips for First-Time Homebuyers” is commodity knowledge any model can generate itself. First-hand experience, original data, and a unique point of view are what earn retrieval. This is the single strongest lever in the entire Google AI search guide.
For local businesses and ecommerce, the Google AI search guide points to Business Profiles and Merchant Center feeds as direct inputs into AI responses. And for measurement, the new Search Console generative AI report will show impressions from AI features as it rolls out beyond the UK.
What Should Your Brand Do Now? 5 Practical Moves
- Stop paying for AI hacks. If a proposal includes llms.txt creation, chunking, or special AI schema as paid deliverables for Google visibility, the Google AI search guide is your reason to walk away.
- Invest in non-commodity content. Original research, real numbers, and first-hand experience are now officially what Google retrieves for AI answers.
- Keep your technical foundation clean. Indexed, snippet-eligible, fast pages are the entry ticket to AI Overviews and AI Mode.
- Measure beyond Google. The “still SEO” framing covers Google only. ChatGPT, Perplexity, Gemini, and Claude each retrieve and cite differently, which is why we test brands across platforms with our SIGNAL Framework.
- Watch the new reports. When the Search Console generative AI report reaches your region, make it part of your monthly review.
Final Thoughts
The Google AI search guide is good news for brands and bad news for hack sellers. The category formerly argued about as GEO or AEO is now named in official Google documentation, and the winning strategy is on record: real content, clean technical structure, authentic authority. The brands that act on this earliest will be the ones AI answers cite by default.

What is the Google AI search guide?
It is an official Google Search Central documentation page, published in May 2026 and updated on June 5, 2026, that explains how to optimize websites for generative AI features like AI Overviews and AI Mode.
Does Google officially recognize GEO and AEO?
Yes. The guide names both terms and defines them, but states that from the perspective of Google Search, optimizing for generative AI search is still SEO rather than a separate discipline.
Is llms.txt necessary for Google AI search?
No. Google states you do not need llms.txt or any special AI text files to appear in generative AI features. Other AI platforms may read such files, but for Google they have no effect.
Do I still need SEO for AI search visibility?
Yes. AI Overviews and AI Mode retrieve content through the core Search index using RAG and query fan-out, so indexed, snippet-eligible pages and strong content remain the foundation.
