Google AI Mode

What is Google AI Mode?

Google AI Mode is a conversational search experience inside Google Search that uses a custom Gemini model to answer longer, multi-part questions. It returns a written response with inline links to sources and lets users ask follow-ups. Google introduced it as a Labs experiment in March 2025 and expanded it to all US users in May 2025.

How it works

AI Mode relies on a technique Google calls query fan-out. It breaks a question into subtopics, runs many related searches at once, then synthesizes the results into one answer. This has a few consequences:

• Wider source pool. Pages can be cited for a sub-question even if they do not rank for the original query.
• Conversation context. Follow-up questions inherit earlier context, so later answers may cite different sources than the first one.
• Fewer, more qualified clicks. Users often get enough from the answer itself; those who click tend to be looking for depth, a tool or a vendor.

Google’s guidance in its AI features documentation is that standard SEO best practices apply and no special markup is required.

Examples

• A user asks “compare SAST and DAST tools for a small engineering team and explain which to start with”. AI Mode runs searches on each tool type, pricing, team size and integration, then cites several vendor and review pages.
• A follow-up, “which of those integrate with GitHub Actions?”, pulls in documentation pages that were absent from the first answer.
• A DevTools vendor finds its integration docs cited in AI Mode even though its homepage does not rank for the head term.

How to apply it

1. Map the sub-questions behind each important buyer query.
2. Make sure each sub-question has a clear, crawlable answer on your site.
3. Keep documentation, pricing and integration pages accurate and public.
4. Monitor AI Mode separately from AI Overviews when you track visibility.
5. Watch Search Console trends for impression and click shifts.
