How does Google decide which businesses show up in AI Overviews?

By Adam Collins, Founder, 3Fold Labs

How does Google choose? AI Overviews use the foundations of Search. Editorial graphic explaining the article topic.

Short answer

Google doesn't publish a separate formula for which businesses appear in AI Overviews. It says they rely on its core Search ranking and quality systems, with no extra requirements. For local businesses, Google points to Business Profiles, and its local ranking rests on relevance, distance and prominence. Often, no AI Overview appears at all.

Google publishes no separate formula for AI Overviews. It says they rely on its core Search ranking and quality systems, with no extra requirements.
Google points to its core Search ranking and its Business Profiles, not a special set of AI rules.
It says AI Overviews rely on its core Search ranking and quality systems, with no extra requirements.

Does Google publish how it picks businesses for AI Overviews?

No. Google says its AI features "are rooted in our core Search ranking and quality systems" and that "there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary."

So when you see a list of "AI Overview ranking factors," know that it is someone's guess, not Google's documentation. Google also says "no third-party tool has access to our internal ranking or AI systems." That applies to anyone selling you a guaranteed spot, including me (more on whether you can pay to be recommended by ChatGPT).

How do AI Overviews find the businesses they mention?

They search Google's own index, then write a summary from what they find. Google describes this as grounding: "relying on our core Search ranking systems to retrieve relevant, up-to-date web pages from our Search index." It also uses "query fan-out," where the model runs a set of related searches behind the scenes.

Google says AI Overviews work "in tandem with" its ranking systems and Knowledge Graph and are "built to surface information that is backed up by top web results." In plain terms: pages and businesses that already do well in regular search are what the summary draws from.

Quote from the post: Pages and businesses that already do well in regular search are what the summary draws from. AI Overviews often don't trigger.
AI Overviews pull from Google's own index, so the summary leans on the same pages regular search already ranks.
Google also says AI Overviews "often don't trigger."

Why do AI Overviews show up for some searches and not others?

Because Google only shows one when it thinks it adds something. Its words: AI Overviews "are only shown when our systems determine that it is additive to classic Search, and as such, often don't trigger."

So if you search "roof repair Palm Coast" and your business isn't in an AI Overview, check first whether there was an AI Overview at all. Also, Google says AI Mode and AI Overviews "may use different models and techniques," so they can name different businesses for the same question.

What role does your Google Business Profile play?

A direct one. Google's AI optimization guide says Business Profiles "can help your products and services to be visible in both AI responses and other Google Search results."

Google's local ranking help says local results "are mainly based on relevance, distance, and popularity." It describes the third factor under the heading Prominence, based partly on "how many websites link to your business and how many reviews you have." It also says "there's no way to request or pay for a better local ranking on Google." For a contractor, that translates to:

  • Relevance: the right primary category and clear service descriptions
  • Distance: an honest service area
  • Prominence: real reviews and links from local and trade sources
Three cards: relevance is the right category and clear services; distance is an honest service area; prominence is real reviews and local links.
Google bases local results mainly on relevance, distance and prominence, and says Business Profiles can help in AI responses too.
Google's relevance, distance and prominence, translated for a contractor.

Google's Business Profile guidelines ask for your real-world business name, an accurate service area, and the fewest categories that fit. This is the heart of search and AI visibility work: Getting found on Google and in AI answers.

What does Google say you can ignore?

More than most AEO vendors would like. For Google Search, its AI optimization guide lists these as things you can ignore:

  • llms.txt and other special AI files
  • "Chunking" your content into small pieces
  • Rewriting content just for AI
  • Seeking inauthentic "mentions"

It also says structured data "isn't required for generative AI search," though it is still useful for rich results (see SEO vs AEO vs GEO). And it warns that making separate pages for every query variation "primarily to manipulate rankings or generative AI responses" violates its scaled content abuse policy. So skip the pile of near-identical "best roofer in [town]" pages.

Two lists: ignore llms.txt, chunking, rewriting for AI and inauthentic mentions; Google lists crawl access, text, matching markup and your profile.
Google's guide says what matters for AI features is crawl access, text content, matching structured data and a current Business Profile.

What makes a contractor's site eligible in the first place?

Basic, crawlable pages. To be a supporting link, Google says a page "must be indexed and eligible to be shown in Google Search with a snippet." Its best practices for AI features:

  • Allow crawling "in robots.txt, and by any CDN or hosting infrastructure."
  • Put important content in text, not only in images.
  • Make any structured data match the visible text.
  • Keep your Business Profile up to date.

Google's guide also says "a site must be included in Search generative AI features in Search Console to be eligible." Google's guide doesn't say on that page whether this is on by default, so look for it in your own Search Console account.

A site Google can crawl and quote starts with one text page per service: Websites.

How can you see whether you're appearing?

In Google Search Console. Google says AI features traffic is counted in the Performance report under the "Web" search type. Its AI optimization guide also refers to a "Generative AI performance report." Check both, and spot-check a few searches yourself, remembering that results vary by person and place.

This is all about Google. ChatGPT, Claude and Grok run their own web searches, and none of their help pages cited here say they use Google's rankings (more on where ChatGPT, Claude and Grok get local business info).

How 3Fold Labs helps

I work on both sides of that: your Business Profile details and the site pages it points to, as SEO, AEO and GEO work. Reviews play a part too, covered in how Google reviews affect AI recommendations. Google doesn't publish how it picks businesses, so no one can promise a spot in an AI Overview.

Here's my Getting found on Google and in AI answers.

FAQ

Do I need schema to show up in AI Overviews?

Google says structured data isn't required for generative AI search. It can still help with rich results, and it must match what's visible on the page.

Can I pay to be in an AI Overview?

Not in the organic answer. Ads can appear above, below, or within AI Overviews, but those are paid ads, not a place in the organic answer. Google also says you can't pay for a better local ranking.

Is AI Overview ranking different from the map pack?

Google hasn't published a separate system. Both lean on its core ranking systems and Business Profile data, but they are different features and can show different businesses.

How long until I show up?

No one can promise a timeline. Google doesn't guarantee indexing or placement.
