Which Sources AI Cites for Local Businesses: Inside 1.97M Citations

When a homeowner asks ChatGPT or Google’s AI for a plumber, the answer is built from a familiar set of websites. A recent BrightLocal study of 1.97 million citations shows which sources AI cites for local businesses, and your Google Business Profile sits at the top of the list.

What did the BrightLocal study look at?

BrightLocal’s study, published August 26, tracked 1,355 business locations in the US, UK and Australia. It ran 60,970 checks across three AI tools: Google’s AI Overviews, Google’s AI Mode and ChatGPT. Those checks produced 1.97 million citations from 116,670 different domains.

BrightLocal sells local SEO software, so treat this as vendor research. Still, the sample is large, which makes it a useful guide to where AI answers about local businesses get their information.

The sources AI cites most for local businesses

A handful of platforms show up again and again. Here is how BrightLocal’s numbers break down.

Two things stand out. First, your Business Profile is the single most important listing you have for AI answers. More than a quarter of all citations went to Business Profiles, and nearly every location had its profile cited at some point.

Second, business websites made up the vast majority of the domains AI pulled from. The big platforms collect the largest share of citations, but the long list of sources is mostly individual companies’ own sites. Your website is part of the conversation, not a bystander to it.

Google is citing itself more in AI Mode

Other vendor data points the same way. Search Engine Journal reported on citation data from Profound showing google.com became the second most-cited domain in AI Mode. Between April 15 and June 30, 2026, google.com’s share of AI Mode citations rose 8.4x. The growth came from Business Profile cards on local queries and from Product Knowledge Panels, and home services was one of the five sectors with the most change.

For a plumber, roofer or cleaning company, that means a large part of what AI Mode says about you may be drawn from your own Business Profile. We walked through that in more detail in our post on Business Profiles as an AI Mode citation source.

What sources does ChatGPT use for local businesses?

ChatGPT behaves differently from Google’s tools. In BrightLocal’s study, Yelp was ChatGPT’s top source and appeared in 80% of its answers. ChatGPT also drew on far fewer domains overall: about 6,000, compared with about 8,500 for AI Overviews and about 81,800 for AI Mode.

In practice, ChatGPT draws from a much narrower pool of sources. If your Yelp listing is thin, outdated or unclaimed, that may be what ChatGPT has to work with when someone asks about your trade in your town.

A separate, broader vendor study supports the idea that each AI tool has its own habits. Semrush, which also sells SEO tools, looked at 126 million US prompts from January to April 2026 for its AI Visibility Index. According to PPC Land’s coverage, it found:

The studies measure different things, so don’t expect the numbers to match. The shared lesson is simple: no single platform covers every AI tool. A business that only maintains its Google listing is leaving ChatGPT to rely on whatever Yelp and other directories happen to say.

If you are weighing paid visibility in ChatGPT instead, our look at ChatGPT ads for local service businesses covers where that stands. Paid placement doesn’t replace accurate listings, though.

Do customers really use AI to find local businesses?

Some do, and many of them still check Google. In BrightLocal’s 2026 survey of 1,227 US consumers, 23% used AI tools during their last local search, and 8% started with AI. Of that AI-first group, 43% checked Google as well, and only 2% relied on AI alone.

Google is still where most local searches begin: 52% started on Google Search and 9% on Google Maps, and 73% started on a phone. But 31% said they use AI monthly for local recommendations. That is a meaningful group, and it is the group these citation studies describe.

Put the two BrightLocal reports together and the takeaway is clear. Many people who use AI to find a contractor also check what it says against Google, and Google’s AI is reading your Business Profile. The same listings do double duty.

Protect your most-cited source: the 4-day edit window

If your Business Profile is the source AI cites most often, its accuracy matters more than ever. That makes a detail reported yesterday worth your attention.

Search Engine Roundtable reported on September 23 that Google’s Business Profile help page gives owners a set window to respond to edits that others suggest for their listing:

“4 days to accept or reject the suggestion.”

After that, according to the report, Google may publish the edit if other public information supports it, such as the business’s own website. Some edits may be applied with no prior notice at all.

Think about what that means in practice. A wrong phone number, closing time or service category suggested by someone else could go live on your profile while you are busy on jobs. From there, it could flow into the AI answers that cite that profile.

How to show up in the sources AI trusts

None of this requires new technology. It requires keeping the listings AI already reads complete and consistent, and making your own website a clear source of truth.

1. Make your Business Profile complete. Fill in categories, services, service area, hours and photos, and keep them current.
2. Claim and update Yelp. It is ChatGPT’s top source in BrightLocal’s data, so it deserves more than a one-time setup.
3. Update Facebook. It was cited for 93% of locations. Check hours, phone number and services.
4. Check the directories in your trade. Review your BBB, Angi or Tripadvisor listings where they apply to your business.
5. Make your website match. Your name, address, phone number, hours and services should agree with every listing.
6. Test what AI says. Ask ChatGPT and Google’s AI Mode for your service in your city, and note which sources they cite.
