AI Overviews are the short AI-written summaries that appear at the top of some normal Google results. AI Mode is a separate, chat-style search where you ask longer questions and follow up in a conversation. Both use Google’s search index and a technique called query fan-out to find sources, but they use different models and often cite different pages.
If you run a website, the difference matters. The two features show up in different situations, draw on sources in slightly different ways, and are reported together in Search Console. This guide explains how each works, what changed in 2026, and what you can actually control.
The short comparison
| AI Overviews | AI Mode | |
|---|---|---|
| What it looks like | A summary box above the normal results, with links to sources | A full-page, conversational answer with links, where you can keep asking follow-ups |
| When it appears | Automatically, on searches where Google thinks a summary helps | When you choose it (AI Mode tab, the search box, or by following up from an AI Overview) |
| Best suited to | Getting the gist of a question quickly | Complex questions that need reasoning, comparisons or several steps |
| How it finds sources | Google’s index, query fan-out, retrieval-augmented generation | The same, usually with more fan-out searches and a longer answer |
| Normal results still shown? | Yes, below the overview | The answer takes centre stage; links sit inside and beside it |
| Where site owners see it | Search Console (overall Performance report and the Generative AI report) | Search Console (same reports) |
What are AI Overviews?
AI Overviews began life as Google’s Search Generative Experience experiment in 2023 and launched under the AI Overviews name in the US in May 2024, before expanding to many more countries. They appear automatically on some searches: you type a question, and a short AI-written summary appears above the usual links, with source links you can click.
Google describes AI Overviews as a way to get the gist of a complicated question quickly, with links as a jumping-off point to learn more. They don’t appear on every search. Google decides when a summary would be useful.
What is AI Mode?
AI Mode is Google’s conversational search. It was first shown in March 2025 as a Search Labs experiment and has since rolled out widely. At its I/O conference in May 2026, Google said AI Mode had passed one billion monthly users.
Where AI Overviews give a quick summary, AI Mode is built for questions that need more thought, like comparing options, planning something or working through several steps. You can ask a follow-up and it keeps the context of the conversation, a bit like a chatbot but grounded in search results.
How both features find and cite sources
Google has explained the mechanics in its documentation for site owners. Two ideas matter most.
Query fan-out
Instead of running only the search you typed, the system runs several related searches across subtopics at the same time. For a question like “how do I fix a lawn full of weeds?”, it might also search for herbicide options, chemical-free removal and prevention. That’s why AI answers often cite pages that don’t rank for your exact words: they rank for one of the hidden sub-searches.
Retrieval-augmented generation (RAG)
The system retrieves relevant pages from Google’s search index and uses specific information from them to write the answer, adding links to the pages it relied on. This is why the normal rules of search still apply. If a page isn’t indexed, it can’t be retrieved, and it can’t be cited.
Google also notes that AI Mode and AI Overviews may use different models and techniques, so they won’t always show the same answer or the same links for the same question. Independent studies have found the two features often cite different URLs for the same search.
What changed in 2026
- Follow-ups flow from AI Overviews into AI Mode. Since Google I/O in May, you can ask a follow-up question directly from an AI Overview and continue in AI Mode, with the conversation’s context carried over.
- A new AI-powered search box. Google redesigned the search box itself to handle longer questions and different inputs (text, images, files), rolling out wherever AI Mode is available.
- AI Overviews can expand. In late August, Google confirmed that some AI Overviews now automatically grow into a longer, AI Mode-style answer when its systems judge a fuller response is more useful.
- Better reporting for site owners. Search Console added dedicated Generative AI performance reports, rolled out to all sites by the end of August, showing how often your pages appear as links in these features.
- An opt-out control. Google also introduced a Search Console setting that lets site owners choose not to appear in its generative AI features at all.
The direction is clear: the line between a normal search, an AI Overview and AI Mode is getting blurrier, and more searches end in an AI-written answer.
How to get your site cited in AI Overviews and AI Mode
Google’s position is simple: there’s nothing special you need to do. Its documentation says there are no extra requirements to appear in AI Overviews or AI Mode. A page needs to be indexed and eligible to show a snippet in normal search. That’s it.
“Nothing special” doesn’t mean “nothing”. In practice, these are the things that make a page more likely to be picked:
- Make sure it’s crawlable and indexed. Check the page in Search Console’s URL Inspection tool. If it isn’t indexed, nothing else matters.
- Don’t block snippets. The same controls that limit snippets in normal results (nosnippet, data-nosnippet, max-snippet, noindex) also limit AI features. Use them deliberately, not by accident.
- Answer sub-questions, not just the main keyword. Because of query fan-out, a page that clearly covers the related questions around a topic has more chances to be retrieved.
- Write content an AI couldn’t produce by summarizing other pages. Google’s 2026 guidance stresses unique, first-hand, “non-commodity” content.
- Add useful images and video. Google says good images and videos can appear in AI responses too.
- Skip the gimmicks. Google has said you don’t need llms.txt files, special AI markup or content chopped into tiny chunks.

How to see whether you appear
AI Overviews and AI Mode traffic has always been counted inside Search Console’s normal Performance report, mixed in with regular search. Since mid-2026 there’s also a dedicated Generative AI report that shows how often your pages were shown as links in these features, broken down by page, country and device.
It has limits. It shows impressions, not clicks, queries or positions. And in Google Analytics, visits from AI Overviews and AI Mode still count as Organic Search. We walk through the report in our Search Console Generative AI report guide.
Do AI Overviews reduce clicks?
It’s the question every publisher asks. Google says clicks from pages with AI Overviews tend to be higher quality, meaning people spend more time on the site. Several independent studies have found lower click-through rates on searches where an AI Overview appears. Both can be true: fewer clicks, but from people who are more interested. We compare the studies in our look at AI Overviews and CTR.
Should you opt out?
For almost every site, no. The opt-out removes your pages from AI Overviews, AI Mode and AI features in Discover, so you lose that visibility and any clicks that come with it. It doesn’t improve your normal rankings. It’s mainly useful for publishers with specific licensing or business reasons for keeping their content out of AI answers.
Frequently asked questions
What is the difference between AI Mode and AI Overviews?
AI Overviews are short summaries shown automatically above normal results. AI Mode is a separate conversational search for longer, more complex questions with follow-ups. Both are powered by Google’s Gemini models and search index, but they use different models and techniques and can cite different pages.
Do I need to do anything special to appear in AI Overviews?
No. According to Google, a page needs to be indexed and eligible for a snippet in normal search. Standard SEO and genuinely useful content are what count.
Can I stop my site appearing in AI Overviews?
Yes. You can use snippet controls on specific pages, or the Search Console setting that opts your whole site out of Google’s generative AI features. Opting out means losing that visibility.
Is AI Mode available everywhere?
AI Mode is available in many countries and languages but not all. Google continues to expand it, so check whether it’s available in your market.
How do I track AI Overviews traffic?
Use Search Console’s Generative AI report for impressions. In GA4, AI Overviews and AI Mode visits are counted as Organic Search, so you can’t separate them there yet.
The bottom line
AI Overviews and AI Mode are two faces of the same shift: Google answering more questions itself and citing a handful of sources. You can’t buy your way in or trick your way in. You get in by being indexed, being useful, and covering the questions around your topic better than anyone else.
