How to rank in Google AI Overviews and AI Mode

To rank in Google AI Overviews and AI Mode, a page has to be chosen as a supporting link in the AI response. Google's rule is short: the page must be indexed and eligible to be shown in Google Search with a snippet, with no additional requirements or special optimizations (opens in a new tab). The site must also be included in the "Search generative AI" setting in Search Console (opens in a new tab), which is the default. Beyond that, Google says optimizing for these features is "still SEO" (opens in a new tab).

This guide is one of a set on how AI assistants find and cite sources. Its sources were checked on September 27, 2026.

Scope and definitions

Work to appear in AI answers is often called answer engine optimization (AEO) or generative engine optimization (GEO). For Google's two features, Google's position is that this work is search engine optimization (SEO) (opens in a new tab). The practice across all search engines and assistants is covered in AI search optimization.

• AI Overviews are AI-written summaries shown on some Google results pages. AI Mode is a separate AI search mode in Google Search. Both link to supporting web pages (opens in a new tab).
• Googlebot is Google's Search crawler, and robots.txt rules for Googlebot control crawling for Search, including its AI features (opens in a new tab). A page is indexed once Google has crawled and stored it, which Google does not guarantee for any page (opens in a new tab).
• A snippet is the text preview shown for a result. The rules nosnippet, data-nosnippet, and max-snippet limit it, and noindex keeps a page out of the index. These are the controls Google gives site owners over what appears from their pages (opens in a new tab).
• Query fan-out is Google's term for "a set of concurrent, related queries generated by the model" (opens in a new tab) to fetch more results for one question.
• Grounding is giving a model retrieved content while it writes an answer. Google describes it as "providing content from the Google Search index to the model at prompt time" (opens in a new tab).

How AI Overviews and AI Mode choose pages

The gate: crawling, indexing, and snippets

Google's AI Overviews and AI Mode can only show pages that are indexed and eligible to appear with a snippet; no special optimization is required (opens in a new tab) (official documentation).

Indexing takes time and is not guaranteed. Crawling can take "anywhere from a few days to a few weeks," (opens in a new tab) repeat requests for the same URL do not speed it up (opens in a new tab), and a sitemap is "merely a hint" (opens in a new tab). Google renders JavaScript with a recent version of Chrome (opens in a new tab), but in a practitioner test of five AI systems, only Gemini ran JavaScript when fetching a live page (opens in a new tab) (one test page). Server-rendered text avoids that problem.

The Search Console setting

Search Console has a setting under Settings > Search generative AI with two main options (opens in a new tab) (a property nested under another property can also inherit its parent's choice):

• Include, the default. Content can appear and be linked in AI Overviews, AI Mode, and the generative AI features in Google Discover, and can help ground their responses.
• Exclude. Content is not shown or linked in those features.

Google's guide says a site must be included to be eligible (opens in a new tab). The setting is not a ranking or inclusion signal elsewhere in Search, does not affect AI training, and generally takes a few days to apply (opens in a new tab). It reached all websites worldwide on August 31, 2026 (opens in a new tab).

How pages are chosen: ranking systems and fan-out

Google says the features are "rooted in our core Search ranking and quality systems" (opens in a new tab), and that both may issue "multiple related searches across subtopics and data sources" (opens in a new tab) to build a response. This means a page may be cited because it ranks for one of those background searches rather than for the words the user typed. Studies fit this:

• In a vendor study of 1.9 million citations, 76.10% of AI Overview citations ranked in Google's top 10 in July 2025 (opens in a new tab). In the same vendor's study of 4 million cited URLs, the figure was 37.9% in March 2026 (opens in a new tab). Ahrefs notes that it improved its citation parsing between the two studies, and suggests that AI Overviews now draw more on the results of fan-out searches (opens in a new tab).
• 53% of the domains AI Overviews consulted were outside the organic top 10, and 27% outside the top 100 (opens in a new tab) (preprint; 4,706 queries; July to September 2025).
• AI Overview sources and organic results had an average Jaccard similarity of 0.18 (opens in a new tab): of all sources returned by either, about 18% were returned by both (peer-reviewed; December 2025).

Many citations come from outside the top 10; the exact share depends on the method and the date.

Where AI Overviews appear

The rate depends on the query and the sample. In Pew Research Center's panel of 900 U.S. adults, 18% of Google searches in March 2025 produced an AI summary, including 60% of searches that began with a question word and 8% of one- or two-word searches (opens in a new tab). A peer-reviewed study found AI Overviews on 51.5% of real user queries in its sample and 17.4% of Amazon shopping queries (opens in a new tab) in December 2025. No study we found measures B2B vendor-selection queries.

AI Mode is used differently. Alphabet reported more than 1 billion monthly active users (opens in a new tab) by July 2026, yet a clickstream panel found that only 0.34% of U.S. Google searches went to AI Mode from January to April 2026 (opens in a new tab) (vendor panel).

Stability and accuracy

Citations change often. When the same queries were run two months apart, only 18% of the pages AI Overviews cited were common to both runs, against 45% for organic results (opens in a new tab) (preprint). Being cited is also not the same as being described correctly. 11.0% of 98,020 claims in AI Overviews were not supported by the pages they cited (opens in a new tab) (preprint). In 1,508 pregnancy and baby-care queries, the AI Overview and the featured snippet on the same page disagreed in 33% of cases (opens in a new tab) (peer-reviewed).

What Google-Extended controls

Google-Extended is a robots.txt token with no user agent string of its own (opens in a new tab). The Google-Extended robots.txt token controls whether content is used for Gemini training and for grounding in Gemini Apps and Vertex AI; it does not affect inclusion in Google Search (opens in a new tab) (official documentation). By Google's account, blocking it does not remove a page from AI Overviews or AI Mode.

One study complicates this. Twenty-one popular publishers that block Google-Extended were never cited by Gemini, and sites that block it were significantly less likely to be retrieved by AI Overviews (opens in a new tab) (peer-reviewed; observational). The gap may reflect which publishers choose to block, not the token itself. To stay visible in the Gemini app, leave Google-Extended allowed; see how to rank in Gemini.

What AI Overviews do to clicks

People click fewer results when an AI Overview appears. How many fewer is contested.

In Pew's panel of 900 U.S. adults, Google users clicked a traditional search result on 8% of visits when an AI summary appeared, compared with 15% when none appeared (opens in a new tab). They clicked a link inside the summary on 1% of visits (opens in a new tab). Read these figures with three limits:

1. Observational data. Searches that trigger a summary are more often questions and long queries, which may get fewer clicks anyway.
2. A reconstructed flag. The browsing was in March 2025, but the researchers re-ran the searches on April 7 to 17, 2025 (opens in a new tab) to see which produced a summary. Results can change in between.
3. A narrow scope. Google, U.S. adults, one month, and no B2B breakdown.

A follow-up on the same panel, controlling for query features and for each panelist, found an AI Overview associated with roughly half the odds of a click (a coefficient of -0.68, or an odds ratio of about 0.51) (opens in a new tab). It is a preprint, and its authors say it cannot show causation. Other estimates differ in size:

Click-through on the queries that show an AI Overview is not the same as a site's total traffic, and Seer saw click-through fall on queries without AI Overviews too. The direction is well supported; the size depends on what is measured. In Seer's data, organic click-through was 35% higher on AI Overview queries where the brand was cited than on those where it was not (opens in a new tab), though Seer says this does not show that citation caused the difference.

The main risk: scaled content abuse

Fan-out tempts site owners to publish a page for every variation of a question. Google's guide says that making separate content for variations such as fan-out queries "primarily to manipulate rankings or generative AI responses in Google Search violates Google's scaled content abuse spam policy" (opens in a new tab). More broadly, Google's spam policies cover attempts to manipulate generative AI responses, and define scaled content abuse regardless of how the content is created (opens in a new tab). A Google Search spam update began on September 24, 2026 (opens in a new tab), and since April 2026 Google may use spam reports to take manual action (opens in a new tab).

Using AI to write is not the problem in itself: Google's quality raters give the lowest rating when almost all of a page's main content is copied or AI-generated with "little to no effort, little to no originality, and little to no added value" (opens in a new tab). The same guidelines say that "the use of Generative AI tools alone does not determine the level of effort or Page Quality rating" (opens in a new tab). Rater scores evaluate Google's systems, not individual pages. The risk is scale without added value.

Steps

Steps 1 to 5 follow Google's documentation. Steps 6 to 11 are recommendations based on the evidence above.

1. Let Googlebot crawl the page. Check robots.txt and your host's bot protection. On Vercel, for example, the Bot Protection ruleset is off by default, but in Challenge mode it serves a JavaScript challenge to traffic that is unlikely to be a browser (opens in a new tab).
2. Get the page indexed. Verify the site in Search Console, submit a sitemap (opens in a new tab), and request indexing once per key URL. Keep lastmod dates true: Google uses them only if they are "consistently and verifiably" accurate (opens in a new tab).
3. Allow snippets on pages you want cited. No noindex, no nosnippet, and no very short max-snippet.
4. Keep Search generative AI set to Include.
5. Decide Google-Extended on purpose. It affects Gemini, not Google Search (opens in a new tab).
6. Answer the sub-questions. List the questions a buyer's query is likely to fan out into, such as price, alternatives, and how results are measured. Give each distinct intent one page and each sub-question a section, with no near-duplicates.
7. Write non-commodity content. Google asks for non-commodity content (opens in a new tab) and says you do not need to split content into tiny pieces or write specially for AI (opens in a new tab). Keep the answer and its supporting facts in visible text.
8. Treat structured data as hygiene, not a lever. It is not required, and there is no special schema.org markup for these features (opens in a new tab); it should match the visible text (opens in a new tab). In a vendor study of 1,885 pages that added it, AI Overview citations fell 4.6% against matched pages, and AI Mode citations did not change significantly (opens in a new tab). Google stopped showing FAQ rich results on May 7, 2026 (opens in a new tab).
9. Earn real mentions. Across 75,000 established brands, branded web mentions correlated at 0.656 with AI Overview visibility and 0.709 with AI Mode visibility, while backlinks showed "very weak correlations" (opens in a new tab) (vendor study; correlational). Google says "seeking inauthentic 'mentions' across the web isn't as helpful as it might seem" (opens in a new tab). See brand mentions and AI recommendations.
10. Update pages when the facts change. In a vendor study of about 17 million citations, AI Overviews showed no preference for fresher pages than organic results did (opens in a new tab). A new date on unchanged content has no documented benefit.
11. Measure. The Generative AI performance report counts impressions of your links in AI Overviews and AI Mode, not clicks, once a site has enough impressions (opens in a new tab). AI-feature clicks are counted inside the Performance report's "Web" search type (opens in a new tab), and GA4's AI Assistant channel excludes AI Overviews and AI Mode (opens in a new tab). See how to measure AI visibility and how to track AI referral traffic. Repeat any manual check: when the same prompt was repeated, ChatGPT and Google's AI returned the same list of brands less than once in 100 runs, and Claude only slightly more often (opens in a new tab) (2,961 runs, November–December 2025; vendor study with a noted conflict of interest).

What the evidence shows and does not show

Antipatterns

An antipattern is a practice that looks helpful but fails or backfires.

1. A page for every question variant. Google calls pages built for fan-out variations to manipulate rankings or AI responses scaled content abuse (opens in a new tab). Instead, write one page per intent, with sections for its sub-questions.
2. Special AI files and markup. Google says no new machine-readable files, AI text files, markup, or Markdown are needed (opens in a new tab), and that llms.txt files neither help nor hurt visibility in Google Search (opens in a new tab). Instead, improve the visible page.
3. Blocking Google-Extended to leave AI Overviews. It governs Gemini, not inclusion in Google Search (opens in a new tab). Instead, use the Exclude setting or the snippet controls.
4. Chasing only the head term. In one vendor's March 2026 data, most AI Overview citations came from outside the top 10 (opens in a new tab). Instead, cover the sub-questions.
5. Buying or faking mentions. Google says inauthentic mentions aren't as helpful as they might seem (opens in a new tab), and its spam policies cover attempts to manipulate generative AI responses (opens in a new tab). Instead, earn coverage.
6. Paying for guaranteed placement. Google lists services "promising improvements for AI experiences and search formats (also known as 'AEO' or 'GEO' tools)" (opens in a new tab) among those to evaluate critically, and says third-party tools "can't guarantee performance" (opens in a new tab). Instead, ask any vendor for its method and its sources.

Checklist

FAQ

How do I track my brand's visibility in Google AI Mode?

Use the Generative AI performance report in Search Console. It counts impressions of links to your site in AI Overviews and AI Mode, not clicks (opens in a new tab), so a mention of your brand without a link does not appear in it. For mentions, run a fixed set of questions many times over several weeks.

How can I keep my content out of AI Overviews and AI Mode?

Set Search generative AI to Exclude; it generally takes a few days (opens in a new tab). The snippet controls and noindex also limit what Google shows (opens in a new tab), but they apply to all of Google Search.

How long does a new page take to appear in AI Overviews?

No study has measured it. Crawling alone can take a few days to a few weeks (opens in a new tab), and indexing is not guaranteed (opens in a new tab).

Can an agency guarantee my pages will appear in AI Overviews?

No. Google says third-party tools have no access to its internal ranking data and "can't guarantee performance" (opens in a new tab).
