Google just published its official guide to optimising for generative AI features on Google SearchAI Overviews, AI Mode, and the rest. If you're a business owner wondering whether your SEO still matters, or whether you need a separate GEO playbook, this is the source worth reading.

We read it so you don't have to wade through developer docs. Below is a plain-English summary with a link back to Google's original page — plus what the guide covers for Google and what it leaves out for ChatGPT, Perplexity, and the rest.

What Google published (and why it matters now)

In June 2026, Google Search Central added a new fundamentals doc: Optimizing your website for generative AI features on Google Search.

It's written for website owners who want official guidance — not forum theories or third-party AEO hacks. The guide covers how Google's AI features work, which SEO practices still apply, which rumoured tactics don't matter, and what's coming next with AI agents.

For business owners, the headline is practical: Google is telling you that good SEO and good AI visibility on Google are the same project. But the guide is scoped to Google Search. That's an important distinction we'll come back to.

Is SEO still relevant for AI search? Google's answer

Yes — explicitly.

Google says its generative AI features are rooted in the same ranking and quality systems as classic search. Two concepts worth knowing in plain English:

TermWhat it means for your site
Retrieval-augmented generation (RAG)Google's AI pulls from pages already in its search index, then summarizes them with clickable links back to sources. If Google can't index you, you won't ground an AI Overview.
Query fan-outFor one question, Google may run several related searches behind the scenes (e.g., "best herbicides" + "remove weeds naturally") to build a fuller answer. More entry points for relevant content to appear.

Google also addresses AEO (answer engine optimisation) and GEO (generative engine optimisation) directly: these are industry terms for improving visibility in AI search experiences. From Google's perspective, optimising for its generative AI features is still SEO.

That aligns with how we talk about it: Google SEO and AI readiness overlap, but they're not identical across every platform. Our Chat GPT SEO Google guide walks through why you can rank on Google and still be invisible elsewhere.

What Google recommends you do

Google groups its advice into three buckets. Here's the business-owner translation.

1. Create content people actually want

Google's strongest message: unique, expert, people-first content matters more than any technical trick.

Specifically, Google recommends:

  • A point of view — first-hand experience beats rehashing what everyone else already said
  • Non-commodity content — "7 tips for first-time homebuyers" adds little; a specific story from your work adds a lot
  • Clear structure — headings, sections, readable paragraphs (for humans, not machines)
  • Images and video where they help — same best practices as regular Google Search
  • Don't spam variations — creating dozens of near-duplicate pages to catch every query angle violates Google's scaled content abuse policy

The core test Google suggests: Would my visitors find this satisfying? If yes, you're aligned with how its systems want to surface content.

2. Keep your technical foundation solid

Google's AI features still depend on crawlable, indexable pages. The guide repeats familiar technical SEO priorities:

  • Meet Search technical requirements — indexed, eligible for snippets
  • Ensure content is crawlable — blocked pages can't feed AI Overviews
  • Follow JavaScript SEO best practices if your site relies on JS frameworks
  • Deliver a good page experience — mobile-friendly, fast, clear main content
  • Reduce duplicate content where you can
  • Use Search Console to catch issues early

None of this is new — and that's the point. Google is saying the crawl/index layer you already maintain is the same layer its AI features depend on.

3. Optimise local and ecommerce details where relevant

For local businesses and online stores, Google highlights:

  • Google Business Profile for local visibility
  • Merchant Center feeds for product listings in AI responses
  • Emerging agentic experiences like Business Agent for conversational commerce

If you sell products or serve a local market, these profiles and feeds are part of how Google surfaces you — in AI answers and traditional results alike.

What Google says you can ignore

This is the section generating the most debate online. Google explicitly lists tactics it considers unnecessary for Google Search generative AI features:

Rumored tacticGoogle's position
llms.txt and similar AI text filesNot required. Google may crawl many file types, but none get special AI treatment.
"Chunking" content into tiny piecesNot required. Google can understand multiple topics on a page.
Rewriting copy specifically for AINot required. Synonyms and meaning matching work without keyword-stuffing for machines.
Inauthentic "mentions" across the webNot helpful. Quality content and spam filtering still apply.
Special structured data for AINot required for generative AI — but still useful for rich results in regular search.

Read the mythbusting section in Google's guide for the full list.

Our take: Google is credible here — for Google. If your only goal is AI Overviews and AI Mode on Google Search, you don't need an llms.txt file because Google says you don't.

But buyers also use ChatGPT, Perplexity, Claude, and Gemini outside Google Search. Those systems are not covered by this guide. Many still benefit from clear machine-readable signals — including llms.txt, structured data, and open crawler access. That's the gap between Google's official scope and full AI search visibility. See our llms.txt validator guide for why it still helps on non-Google assistants.

Where Google's guide stops — and GEO Fix starts

Google's guide answers: How do I show up in Google's AI features?

It does not answer: Can ChatGPT read my site? Is a competitor getting recommended because my bots are blocked? Do I have the files and CMS steps to fix it this week?

That's the blind spot we see constantly:

Google's guide coversWhat business owners still need
Content quality for GoogleWhether non-Google AI crawlers can reach your pages
Crawlability for GooglebotWhether GPTBot, OAI-SearchBot, PerplexityBot are blocked in robots.txt or Cloudflare
llms.txt not needed for Googlellms.txt still useful for ChatGPT, Perplexity, and similar systems
General technical SEOGenerated robots.txt, llms.txt, schema files + install steps for Shopify, WordPress, Wix, Webflow

Google tells you the strategy. GEO Fix checks whether AI systems can actually access your site — then ships the corrected files if they can't. Most tools show a score; we deliver the fix.

If Google's guide confirms your SEO foundation is solid but ChatGPT still names your competitor, the problem is likely in the second column — not your content quality on Google.

Three checks that go beyond Google's doc:

  1. Test live AI crawler access — not just whether Googlebot can index you. See our guide on AI bots blocked in robots.txt.
  2. Run an AI visibility scan — covers robots.txt, llms.txt, structured data, and security-layer blocks in one pass. Our GEO tool guide explains what to look for.
  3. Deploy fixes, not dashboards — if blockers exist, you need files and CMS instructions, not another monthly subscription.

Google's guide is the right starting point for Google. Full AI search readiness means closing the gaps Google doesn't address.

FAQ

Google published it in Search Central documentation: [Optimizing your website for generative AI features on Google Search](https://developers.google.com/search/docs/fundamentals/ai-optimization-guide?hl=en). Last updated June 2026.

No. Google explicitly states that optimising for its generative AI features is still SEO. Terms like GEO and AEO describe work focused on AI visibility, but Google treats it as part of the search experience — not a separate discipline.

Not for Google Search generative AI features. Google says you don't need llms.txt or similar machine-readable files to appear in AI Overviews. For other AI assistants (ChatGPT, Perplexity, etc.), llms.txt can still help — but that's outside Google's guide.

No. Google says structured data isn't required for generative AI search, though it remains useful for rich results in standard search. Continuing schema markup as part of your overall SEO strategy is still a good idea.

Google's guide optimises for Google. ChatGPT uses its own crawlers and retrieval systems. You can meet every Google recommendation and still be blocked or hard to parse for non-Google AI. That's when an [AI visibility check](https://getgeofix.com/gb) with GEO Fix's Express Check makes sense.

Google's guide is strategic documentation for Google Search. A GEO tool tests whether AI systems can actually reach and interpret your site — including crawlers and files Google doesn't discuss. GEO Fix goes further and generates the corrected files plus CMS install steps.

What to do next

Key takeaways:

  • Google's official AI optimisation guide confirms: good SEO is still the foundation for AI Overviews and AI Mode on Google Search.
  • Google says you can skip llms.txt, content chunking, and AI-specific rewrites — for Google. Other AI assistants are a different story.
  • If Google looks fine but ChatGPT doesn't, the gap is usually technical access — blocked bots, missing structure, or security rules — not content quality.
