SEO for AI Search: AI Overviews, AI Mode & Chatbots

What Google officially says (checked 2 October 2026)

Google Search Central publishes two pages for site owners: "AI features and your website" and a guide to optimizing for generative AI features. Both say the best practices for SEO remain relevant, because AI Overviews and AI Mode use Google's core ranking and quality systems to pick the pages they link to.

To appear as a supporting link, a page must be indexed and eligible to be shown in Google Search with a snippet. Google says there are no additional technical requirements.
The site must also be included in the Search generative AI features setting in Search Console. Inclusion is the default.
You do not need new machine-readable files, AI text files such as llms.txt, special markup, or a special schema.org type to appear in these features.
You do not need to split content into tiny chunks or rewrite it in a special style for AI; Google says there is no ideal page length.
robots.txt rules for Googlebot, and snippet controls such as nosnippet, data-nosnippet, max-snippet, and noindex, are how you limit what appears.

The SEO basics that matter most for AI answers

Google's own list of fundamentals that "continue to be worthwhile" for AI features is short and practical:

Allow crawling in robots.txt and in your CDN or hosting firewall.
Make pages easy to find through internal links.
Provide a good page experience on phones and desktops.
Put important content in text, not only inside images or video.
Support text with high-quality images and video where they help.
Keep structured data accurate and matching the visible text.
Keep Merchant Center and Business Profile information up to date if you sell products or serve a local area.

Write pages that AI answers can cite

AI answers link to pages that answer a question clearly and can be trusted. That is the same writing that works for people, and none of it requires a special format.

Answer the main question near the top in one or two plain sentences, then explain the details.
Use descriptive headings that match the questions people ask, such as "How much does it cost?".
Show where facts come from: name the source and the date you checked it, and link to it.
Add what only you can add: first-hand testing, your own examples, photos you took, local knowledge, or original data.
Keep facts current. Update prices, rules, and dates when they change, and say when the page was last checked.
Say who wrote the page and why they can be trusted, and make contact information easy to find.

Other AI search tools: ChatGPT, Copilot, and Perplexity

AI assistants with web search, such as ChatGPT search, Microsoft Copilot, and Perplexity, also read public web pages and link to sources. Each has its own crawler, and you control access through robots.txt using the user-agent names each company publishes, such as OAI-SearchBot for ChatGPT search. Blocking a search crawler can stop your pages being shown as sources in that tool.

Microsoft's Copilot uses Bing's index, so verifying your site in Bing Webmaster Tools and submitting your sitemap there helps it find your pages. The same people-first content that ranks in Google is what these tools tend to cite.

How to measure AI visibility

Search Console includes a Generative AI performance report showing impressions in AI Overviews and AI Mode by page, country, device, and date, with a separate report for Discover. These impressions are also counted in the normal Performance report, so do not add the two together.

Clicks from AI features are counted as Google Search traffic, so watch whether the pages that appear in the AI report also bring visits and sign-ups in your analytics. For other assistants, look for referral visits from their domains in your analytics tool.

Frequently asked questions

What is generative engine optimization (GEO)?

A name for optimizing content to be cited in AI-generated answers. Google's guidance says it is still SEO: indexable, crawlable, helpful pages with clear text. It says special files, markup, or chunking are not needed.

Do I need an llms.txt file?

Not for Google. Google's generative AI optimization guide says you do not need new machine-readable or AI text files, because Google Search does not use them.

How do I get my website into Google AI Overviews?

Make sure the page is indexed and eligible for a snippet, keep the Search generative AI features setting on in Search Console, and publish a clear, accurate answer to the question. Inclusion makes a page eligible; it does not guarantee it will be shown.

Can I stop my content appearing in AI Overviews?

Google points to its normal controls: nosnippet, data-nosnippet, max-snippet, and noindex limit what is shown, and Search Console has a setting for Search generative AI features. Blocking Googlebot in robots.txt removes the page from Search as a whole.

Does structured data help with AI search?

It is not required, and Google says there is no special schema for AI features. Accurate structured data that matches the page still helps Search understand it.
