AI Mode

How it works

AI Mode is a separate tab and experience inside Google Search. A user asks a question in natural language, often a long or comparative one, and gets a written answer with links to supporting websites. They can then ask follow-up questions in the same thread, the way they would with a chatbot.

The engine underneath is query fan-out. Google describes it as "issuing multiple related searches concurrently across subtopics and multiple data sources," then combining the results into one response (Google, March 2025). Google's Search Central documentation says this lets it "display a wider and more diverse set of helpful links" than a single classic search would (Search Central). The practical effect: a page can be pulled into an AI Mode answer for a sub-question it answers well, even when the user never typed that sub-question.

When Google is not confident in the quality of an AI response, AI Mode falls back to showing a set of regular web results, according to the launch post.

How it differs from AI Overviews

AI Overviews and AI Mode share technology, and Google covers both on the same Search Central page. The difference is in when they appear and what the user is doing:

• AI Overviews show up automatically above classic results, and only when Google's systems decide a summary adds something. Many searches do not trigger one.
• AI Mode is opt-in. The user chooses it, usually for complex questions or comparisons, and stays in a conversation.

Since May 2026, the two connect: a user can ask a follow-up directly from an AI Overview and continue in AI Mode with the context carried over, live worldwide on desktop and mobile (Google, May 2026).

What changed, 2025 to 2026

• March 5, 2025: Google announced AI Mode as an experiment in Search Labs, opt-in and starting with Google One AI Premium subscribers, powered by a custom version of Gemini 2.0 (Google).
• May 20, 2025 (Google I/O): Google began rolling out AI Mode to everyone in the US with no Labs sign-up, powered by a custom version of Gemini 2.5. It also announced Deep Search, which runs hundreds of searches to build a cited report, agentic tasks such as event tickets and restaurant reservations, and a shopping experience built on the Shopping Graph with virtual try-on and agentic checkout. Google said many of these features would start in Labs (Google).
• May 19, 2026 (Google I/O): Google said AI Mode "has surpassed one billion monthly users" and that queries had been "more than doubling every quarter since launch." Gemini 3.5 Flash became the default AI Mode model for everyone globally, and Personal Intelligence in AI Mode expanded to nearly 200 countries and territories across 98 languages. Google also announced background information agents for AI Pro and Ultra subscribers, agentic booking for local experiences and services coming to everyone in the US, and Google calling businesses on a user's behalf in categories like home repair, beauty and pet care (Google).

How Search Console reports it

Google does not give AI Mode its own clicks report. Per the Search Console Help documentation (Google):

• A click on an external link in AI Mode counts as a click.
• Impressions follow the standard Search rules.
• Position is calculated the same way as on a standard results page.
• A follow-up question is treated as a new query, with its own impressions, positions and clicks.
• Data from Search Labs experiments is excluded.

All of this lands inside the Performance report under the "Web" search type, mixed with classic results. In June 2026 Google introduced Search Generative AI performance reports, which show how often your URLs appeared in generative AI features such as AI Overviews and AI Mode, broken down by page, country, device and date. The report covers impressions. As of August 31, 2026, Google says it has rolled out to all websites worldwide (Search Central Blog).

What to do about it

Google's official position is that "There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary" (Search Central). Treat that as the baseline, then act on what it implies:

1. Make sure you are eligible. Pages must be indexed and allowed to show a snippet. Check robots.txt, CDN or firewall rules, and any nosnippet or max-snippet tags you set years ago.
2. Cover the sub-questions. Because of fan-out, AI Mode rewards pages that answer the specific questions inside a bigger decision: pricing models, integrations, comparisons, limitations. Keep that content in plain text, linked internally.
3. Keep feeds and profiles current. Google names Merchant Center and Business Profile data in its guidance, and AI Mode's shopping and booking features draw on that data.
4. Read Search Console differently. Split long, conversational queries from short ones in the Performance report, and use the generative AI report to see which pages earn AI impressions. Our guide to measuring AI search performance covers setting up that tracking.

Common misconceptions

"AI Mode needs its own SEO." Google says existing SEO best practices apply and that no new machine-readable files, AI text files or special schema.org markup are required.

"AI Mode traffic is invisible." Clicks and impressions are counted in Search Console. They are blended with classic Web results, which makes them hard to isolate, though the generative AI report now separates impressions.

"Blocking Google-Extended removes you from AI Mode." Google lists Google-Extended as a control for AI training and grounding in other Google systems. For what appears in Search, including AI features, it points to Googlebot rules and snippet controls.

The useful habit is to track the actual questions buyers ask across AI Mode and the other engines they use, and watch which sources get cited over time.
