Last checked: 12 November 2026. AI search is changing quickly; we update this page as Google's guidance changes.
What Google says
Google's own guidance for site owners is clear on the basics:
- There are no additional requirements and no special optimisations needed to appear in AI Overviews or AI Mode. Pages must be indexed and eligible to show with a snippet.
- You do not need new machine-readable files, "AI text files" or special markup to appear in these features.
- Traffic from AI features is included in Search Console's Performance report, under the Web search type.
- Standard controls such as
nosnippet,data-nosnippet,max-snippetandnoindexlimit what can be shown.
Be sceptical of anyone selling a special "AI SEO" file or trick as a shortcut.
What stays the same
- Being crawlable, indexed and fast.
- Clear, helpful, accurate content that answers real questions.
- Strong internal linking and good page experience.
- Structured data that matches visible content.
- An accurate, active Google Business Profile.
- Real reputation: reviews, mentions and links.
What changes in practice
| Change | What to do |
|---|---|
| Simple factual questions are increasingly answered on the results page | Expect fewer clicks for basic definitions; focus on pages that help people decide and act |
| AI answers draw on several supporting pages | Be the clearest, most trustworthy source on your topics, with original detail |
| People ask longer, more specific questions | Cover the real questions your clients ask, in their words |
| Brand matters more | Make your business easy to recognise and verify: consistent details, reviews, expertise |
How to measure the impact
- In Search Console, watch impressions and clicks for your key pages and queries over time. If impressions hold but clicks fall for simple informational queries, AI answers may be satisfying those searches.
- Track enquiries from organic search in your CRM. That is the number that matters, and it is less affected by changes in how answers are displayed.
The bottom line
Do the fundamentals better than anyone else in your market, and make your content the kind an AI answer would want to cite: specific, accurate, expert and genuinely useful.
