AI Overview is the AI-written summary Google shows at the top of some searches, with links to the pages that support the answer. In Portuguese it is called Visão geral criada por IA. There is no button, sign-up or markup to get into it. A page only needs to be indexed and eligible to appear in search with a snippet. The rest is good SEO, and no site controls or guarantees its presence in Google’s AI summary.
This guide follows what Google wrote in its documentation for site owners and in the Search Help Center. Where Google says nothing, this text says nothing either.
What Google’s AI Overview is
AI Overview is an AI-generated block of text that appears on the results page with a summary and links so the reader can go deeper. The help center defines it as a summary with key information and links to dig further. The page itself warns that the AI can make mistakes and that readers should check anything important in more than one place.
For a site owner, the useful part is this. The summary doesn’t replace the links, it carries them along. Google’s documentation for site creators says that AI Overviews and AI Mode show relevant links and make room for more types of sites to appear.
AI Mode is something else. It is a Search mode for longer questions, with reasoning and comparison. The summary sits inside the regular results page. Both follow the same eligibility rules for your site, which is why this guide covers both when the rule is shared.
When AI Overview appears
It appears when Google’s systems conclude that generative AI helps more than the list of links alone. The help center gives the example of a search that requires pulling together information from several sources. The documentation for sites adds that it doesn’t appear very often, because it is only shown when it adds to classic Search.
In practice, Google doesn’t publish a list of which searches get the block. It was designed for complicated topics and questions, where an overview helps more than ten loose links, and the display can change from one search to another.
There is also a country and language limit. The help center keeps the list of where the feature is available, and it’s worth checking it before planning anything around it.
Where AI Overview gets its sources
The summary builds the answer from pages found in Google Search itself, and shows links to them. Google describes a technique called query fan-out. Instead of running a single search, the system fires off several related searches, on different subtopics and data sources, and uses what it finds to build the answer.
Imagine someone asking how to register as a MEI (Brazil’s individual micro-entrepreneur status). The question has parts inside it, such as monthly cost, documents, permitted activities and what happens afterward. The system can search each part separately. According to Google, this lets it show a broader and more varied set of links than a classic search would.
Two consequences that Google itself documents.
- Because the system also searches subtopics, the set of links can include pages that classic search wouldn’t show at the top. Google doesn’t say that ranking position decides, and this text doesn’t either.
- The set of answers and links varies. AI Overview and AI Mode can use different models and techniques, so the same question doesn’t always return the same sources.
Google also doesn’t reveal how many sources are used, or how much weight each one carries. Any number you read about this comes from third-party tests, not from Google.
What Google requires for a page to appear
To appear as a supporting link in AI Overview, the page must be indexed and eligible to appear in Search with a snippet. The documentation says there is no additional technical requirement, no specific optimization is needed and no special file or markup is required.
This knocks down some ideas that are going around.
| What people say | What Google documents |
|---|---|
| Is there a special schema for the AI summary | Adding special schema.org structured data is not required |
| Do you need a separate text file for AI | You don’t need to create machine-readable files or AI text files |
| Is there a specific optimization to get included | No specific optimization is needed |
| Does following everything guarantee you’ll appear | Indexing and display are not guaranteed |
The last row of the table is the most important one. Google states plainly that a page can follow every recommendation and still not be crawled, indexed or shown. If anyone sells you a guarantee of appearing in AI Overviews, that promise contradicts Google’s own documentation.
What your site can do
What your site can do is regular SEO, done well. Google’s documentation lists the practices that still apply to AI features, and you can turn that list into tasks.
Make the page indexable
Check that robots.txt doesn’t block Googlebot and that no CDN or hosting server blocks crawling. Pages with noindex are left out of every result, summary included. Search Console shows indexing issues and is the first place to look.
Answer the question right at the start
This part is our recommendation, not a Google requirement. The documentation asks for helpful, reliable content made for people, and a direct answer at the top of the page is the simplest way to meet that. Readers want to know whether the page solves their problem. A paragraph of two or three sentences at the top with the complete answer serves the reader and gives the system a clear passage to cite. This page does that in the first paragraph.
Put important content in text
Google recommends that important content be available as text. If price, address, hours and step-by-step instructions exist only inside an image, the page doesn’t offer them as text. Good quality images and videos work as a complement, not a replacement.
Use internal links
Google lists internal links among the practices that help content get found. When a topic has several articles on your site, they should link to each other.
Take care of the page experience
A good page experience is also on the list of practices that still apply. The guide on how to make your business show up on Google covers the basics of this part.
Keep structured data consistent with the text
Structured data is not required. If your site already uses it, Google asks that it match the visible text on the page. Markup that says one thing while the page says another is an error.
Keep your Business Profile up to date
The documentation mentions the Business Profile and Merchant Center among the information that must be kept current. For a local business, the Profile is part of what Google knows about you. Our guide to Google Business Profile shows how to create and maintain it.
What you can’t control
Almost everything that matters in AI Overviews is out of the site owner’s hands. You can improve your page, but you can’t decide whether it gets included.
- Whether the summary appears. Google decides per search, at each moment.
- Which sources are included. The set varies between searches and between models.
- What the summary says. The text is generated and may contain errors, as Google itself warns.
- How much traffic comes back. Google says clicks from pages with an AI summary tend to be higher quality, with more time on the site. It doesn’t say click volume goes up.
Control exists only in the opposite direction, limiting what appears. The nosnippet, data-nosnippet, max-snippet and noindex directives restrict what Google shows from your page, and the Googlebot robots.txt controls crawling. Since AI is part of Search, these limits apply to it too. To control the use of your content for AI training in other Google systems, the way is Google-Extended. If your content keeps appearing after you set a control, Google says to wait for a new crawl, which can take anywhere from several days to months.
How to measure the AI summary on your site
There is no separate report. According to the documentation, sites that appear in AI features are counted in the overall Search Console traffic, in the performance report, under the Web search type. So you see clicks and impressions, but you can’t separate how many came from the summary.
You can track the rest in Google Analytics, such as conversions and time on site. If your GA4 doesn’t record WhatsApp contacts, forms and phone calls as conversions, that measurement is blind. The Google Tag Assistant guide shows how to test whether your tags work.
AI Overviews, GEO and SEO: where this article ends
This article covers only Google’s AI summary. The bigger topic, being cited by ChatGPT and Gemini too, is what the acronym GEO covers, and it has its own guide, the one on SEO for AI. That’s where you’ll find the overview. Here we kept to the Google side.
