Google AI Mode explained: what it is, how it differs from AI Overviews and what it means for your site

Quick summary

• AI Mode is a tab in Google Search where you converse with Google's AI: you ask a question, get an answer with links to sources and can ask follow-ups.
• Google introduced it on 5 March 2025 as an experiment in Labs, aimed at questions that need comparison, reasoning or exploration.
• It uses query fan-out: it splits your question into many related searches and combines the results. That opens the door to pages that answer a subtopic well.
• The requirements to appear are the same as for AI Overviews: a page that's indexed and eligible to show with a snippet. But Google warns that the two may use different models and techniques, so results don't match.

What AI Mode is

When Google announced AI Mode, it described it as a search mode that expands what AI Overviews can do "with more advanced reasoning, thinking and multimodal capabilities". Its example shows the intended use: "what's the difference in sleep tracking features between a smart ring, smartwatch and tracking mat". A question like that used to take several searches; in AI Mode it's answered in one go, with links and the option to keep asking.

According to the same announcement, AI Mode combines the model with Google's information systems: the web index, the Knowledge Graph, real-world information and shopping data for billions of products.

How it differs from AI Overviews

	AI Overviews	AI Mode
Where it appears	Above the regular results	In its own tab
When	Only when Google thinks it adds value	When the user chooses it
Conversation	No	Yes, with follow-ups
Question type	Getting to the gist quickly	Exploring, comparing, reasoning

Google's documentation adds something to keep in mind: AI Mode and AI Overviews may use different models and techniques, so the set of responses and links varies. Appearing in one doesn't guarantee appearing in the other. That's why it makes sense to measure them separately, and separately from Gemini, Google's chat app, which is a different surface again.

How it picks sources: query fan-out

Google explains in its guide to optimizing for generative AI that its AI features rely on two techniques:

• Retrieval-augmented generation (RAG, or grounding): the system retrieves relevant pages from the Search index using its core ranking systems and generates the answer from them, showing links to the pages that support it.
• Query fan-out: the model issues a set of concurrent, related queries to gather more information. Google's example: for "how to fix a lawn that's full of weeds", fan-out queries might include "best herbicides for lawns", "remove weeds without chemicals" and "how to prevent weeds in lawn".

The practical consequence: your page isn't just competing for the question the user typed, but for each sub-question. A page that thoroughly answers "how much does it cost to maintain a Webflow site" can make it into an answer to "Webflow or WordPress for my company site?".

What not to do with this

The obvious temptation is to create one page per possible fan-out query. Google saw it coming: its guide says that creating content for every query variation (including fan-out queries) mainly to manipulate generative AI responses violates its scaled content abuse policy, and is an ineffective strategy anyway. Its systems understand relevance even without an exact keyword match.

What works is having complete pages on the topics you genuinely know, covering the natural sub-questions in clear sections.

What changes for your site

More long, conversational questions

Google observes that people ask longer, more specific questions in its AI experiences, and follow up. AI Mode makes that even more pronounced because it's a conversation. Pages that address concrete situations (company size, industry, country, budget) have more places to fit.

Explicit comparisons

AI Mode is designed for comparing options. If you sell something with clear alternatives, an honest comparison page with verifiable facts is direct material for those answers. An inflated one isn't: Google's systems cross-check against other sources.

Preferred sources

Google has a preferred sources feature that lets users choose sites they want to see more of. According to the changelog of Google's Search documentation, from 27 May 2026 it started rolling out to AI Mode and AI Overviews as well. If you have a loyal audience, asking them to mark you as a preferred source is a legitimate move.

A quick test you can run today

Pick three buyer questions that involve a comparison ("X or Y for a 20-person company?", "best Z under £100 a month"). For each one:

1. Ask it in AI Mode in a private window, and note which brands are mentioned and which pages are linked.
2. Run the same search in regular Google and check whether an AI Overview appears and what it cites.
3. Repeat both a couple of days later.

You'll usually see that the two surfaces cite different pages, and that both shift between runs. That's the clearest argument for measuring them separately and for not drawing conclusions from one screenshot.

How to measure AI Mode

• Search Console: per Google's documentation, appearances in AI Mode are counted in the "Web" search type of the Performance report. Since 2026 there's also a dedicated generative AI report with impressions by page, country, device and date, available to all sites since 31 August 2026.
• Google Analytics: AI Mode counts as organic search. GA4's default channel group documentation says so explicitly: the "AI Assistant" channel excludes AI Overviews and AI Mode, which go into "Organic Search".
• Question sampling: to know whether you appear for your buyer questions, and who appears instead, you have to ask and repeat them. Citable measures AI Mode as its own engine, separate from AI Overviews and Gemini, from the mid-tier plan up. You can see which engines each plan includes on the pricing page.

FAQ

Is AI Mode available in my country and language?

Google launched it in 2025 as a Labs experiment, first by invitation to Google One AI Premium subscribers, and availability by country and language has changed since. We don't assume it here: check by searching on Google from your country and in your language.

Do I need to optimize differently for AI Mode than for AI Overviews?

Google says the requirements are the same: an indexed page eligible to show with a snippet, with no extra requirements. But the two may use different models and techniques, so it's worth measuring them separately.

Can I see in Analytics how many visits come from AI Mode?

Not separately. GA4 counts clicks from AI Mode and AI Overviews as organic search because they arrive with a Google referrer. To see your impressions in AI features, use Search Console's generative AI report.

Does AI Mode use the same AI as Gemini?

Google announced AI Mode with a custom version of Gemini 2.0, connected to Search's systems. Gemini as a chat app is a separate product with a separate interface, and its answers don't necessarily match AI Mode's.

Conclusion

AI Mode turns search into a conversation and spreads your question across many queries. For your site, that rewards pages that answer specific subtopics well and punishes the strategy of manufacturing pages for every variant. The requirements are classic SEO; what's new is that you have to measure it as an engine in its own right, with its own answers.
