What are AI Overviews and AI Mode?
AI Overviews are AI-written summaries that appear above the regular results for many searches, with links to the pages they draw from. AI Mode is a separate, conversational search experience that handles follow-up questions and also cites sources. Both are built on Google's normal search index.
What makes a page eligible to appear?
Google says there are no extra technical requirements beyond normal Search. A page needs to be indexed and eligible to show in results with a snippet. You don't need special AI markup, an AI-specific file or a particular schema type. The entry ticket is ordinary SEO:
- Googlebot can crawl the page, so it isn't blocked in robots.txt.
- The page is indexed. Check it with URL Inspection in Search Console.
- The page is allowed to show a snippet, so it doesn't use nosnippet or a very small max-snippet value.
How does Google choose which sources to cite?
Google hasn't published a formula. AI Overviews pull specific passages that answer the question, so a page doesn't have to rank first overall to be cited. A clear passage on a page further down the results can still be picked. Strong rankings help, but they aren't the whole story.
Across industry studies and Google's own guidance, the same qualities keep coming up:
- A direct answer in the first sentence or two under a heading that matches the question.
- Specific facts: numbers, steps, names, prices, conditions and exceptions, not vague generalities.
- Original information: your own data, examples and experience, rather than a rewrite of what already ranks.
- Clear authorship and signs that the writer knows the subject, which Google calls E-E-A-T (experience, expertise, authoritativeness and trust).
- Up-to-date content for topics that change, with old figures and screenshots refreshed.
How to structure content for AI Overviews
- Use headings that ask the questions your customers ask, such as 'How long does a boiler service take?'
- Answer in two or three plain sentences straight after the heading, then go into detail.
- Use numbered lists for steps and tables for comparisons, prices and specifications.
- Keep one idea per section, so each passage makes sense if it's quoted on its own.
- Add structured data that describes the page truthfully. See how to add structured data and our schema markup guide.
Does structured data help with AI Overviews?
Google says no special schema is needed to appear in AI features. Structured data still helps Google understand what your page is about and who's behind it, such as your business, products and authors, which supports everything else. Treat it as good housekeeping, not a shortcut.
How to track your AI Overview visibility
At the time of writing, Search Console counts clicks and impressions from AI features inside its normal web search totals, so you can't cleanly separate them. A practical approach is to:
- Watch for queries where impressions rise but clicks fall, which often means an AI Overview is answering the question.
- Run your most important searches yourself and note whether you're cited.
- Track how AI assistants talk about your brand. Pagelyt's AI visibility check asks AI assistants about your business and records whether you're mentioned.
Can I stop my site appearing in AI Overviews?
Only with the same controls that limit normal snippets: the nosnippet rule, data-nosnippet on specific sections or a max-snippet limit. These also shrink your regular search listing, so for most businesses the cost is higher than the benefit.

Frequently asked questions
Do I need to rank number one to appear in an AI Overview?
No. AI Overviews cite passages that answer the question well, and these can come from pages that rank lower down. Ranking well still improves your chances.
Do AI Overviews reduce clicks to websites?
Many publishers report fewer clicks on searches that show an AI Overview, especially simple factual ones. The clicks that remain tend to come from people who want more depth, which favours detailed, original pages.
Does llms.txt help with Google AI Overviews?
Google has said it doesn't use llms.txt for Search or AI Overviews. It may still be useful for other AI tools. See our guide to what llms.txt is.
How long does it take to show up in AI Overviews?
There's no set time. Once a page is indexed and Google has recrawled your changes, it becomes eligible straight away. Whether it's cited depends on the query and the competing pages.
Is optimising for AI Overviews different from SEO?
Mostly no. Google says the same SEO best practices apply. The main difference is in how you write: clearer, more direct answers that work as standalone passages.
