The directories AI reads before it recommends a local pro

Which directories AI reads before recommending an electrician, a roofer or a dental course: real counts from five AI systems, and which ones named the business.

The short version

We tracked which websites five AI systems read before recommending three kinds of local business, over the same three weeks (30 September to 20 October 2026). The directories differ by trade and by AI system.

How we collected this

The short answer: every day, the same buying questions, five AI systems, and every link the answers cited.

LLM Visibility Lens, our tracker, asks each business's buying questions every morning from the business's own area, logged out. It asks in ChatGPT, Gemini, Google AI Mode, Google AI Overviews and Perplexity, and records every website each answer links to and which businesses it names.

This article covers three businesses with 17 tracked questions each:

The counts below are the number of AI answers that cited each site between 30 September and 20 October 2026. We leave out the businesses' own websites and competitors' websites; those are covered in which websites ChatGPT trusts. The charts also leave out booking pages, utilities and store pages, which we mention in the text.

What this can't tell you. It's three businesses in three markets, not a survey of every trade. A directory that matters in Vancouver may not matter in Texas. It also doesn't cover dentists who see patients, or lawyers. We've started a separate study for those and will publish it when it has two full weeks of data.

I sell this tracker, so weigh my view. Kato's numbers can be checked in the demo.

Electricians

The short answer: Canadian home-service directories and "best of" list sites, plus Google's own pages.

BC Hydro, the power utility, also appeared in 138 answers, mostly for outage and safety questions, and Home Depot's store pages in 77 Perplexity answers.

Two things surprised me.

The regulator. ChatGPT linked Technical Safety BC in 58 answers. It reads the licensing body before saying who's qualified. Make sure your licence details there match your business name exactly.

Booking pages. Google's AI Mode linked public booking pages from scheduling apps (Housecall Pro in 82 answers, Jobber in 65). If you use one, its public page is something AI can read, so make sure it shows your full business name and areas.

Angi barely appeared for the electrician: 3 answers. In Canada, HomeStars does that job.

Roofers

The short answer: the big American home-service marketplaces, BBB and Yelp, plus manufacturers' contractor pages.

Yelp's desktop site appeared in another 77 answers.

The manufacturer pages are the hidden gem. AI read GAF in 27 answers and Owens Corning in 12. Both list certified installers. If you're certified, make sure your listing is complete.

There's an oddity worth knowing: Perplexity linked Checkatrade, a UK directory, in 42 answers for a Massachusetts roofer. AI makes mistakes about geography too.

Dental training

The short answer: almost no consumer directories. Professional bodies, the regulator and course listings do the work.

Further down: the University of Florida dental school (70 answers), the Academy of General Dentistry (67), Google Maps (67), CE Broker's course listings (42, Florida's continuing-education tracking system) and the American Dental Association (24, plus its CE and accreditation pages).

For a professional audience, AI goes to the official and professional sources: who's accredited, who counts toward licence renewal, which maker endorses the course. Yelp appeared in 49 answers, but it's not where the decision is made.

This is the pattern I expect for dentists and lawyers who see the public too: a mix of consumer directories and the profession's own registers. The separate study will show how much of each.

Each AI system reads different directories

The short answer: Google's AI reads Google, Gemini reads Maps, and ChatGPT and Perplexity read lists and BBB.

Which directories each AI system reads: Gemini reads Google Maps, Google AI Mode and AI Overviews read Google pages and Yelp, ChatGPT and Perplexity read BBB and list sitesMost-cited source that was not a business website, for the electrician, roofer and dental training institute. ChatGPT: BestProsInTown 63, BBB 61, Google pages 82. Perplexity: BestProsInTown 94, BBB 57, Straumann 119. Gemini: Google Maps 166, 135 and 67. Google AI Mode: Google pages 141, Angi quote pages 211, Google pages 40. AI Overviews: Google pages 106, Yelp 99, Instagram 118.

So "get on the right directories" depends on which AI your customers use:

Being listed isn't the same as being named

The short answer: AI often reads a directory and then names someone else from it. What decides it is how strong your profile is there.

The clearest contrast is Google Maps in Gemini:

Same AI system, same kind of source. The difference is how each business's Google profile stacks up in its area for those questions. The electrician is named most for Burnaby and Vancouver; for Coquitlam and Surrey, Gemini reads Maps and names others. We showed the same pattern in Google Business Profile and AI answers.

A listing with few reviews, missing services or the wrong areas mostly helps the competitors listed next to it.

What to do, by trade

Start by finding out which directories AI actually reads for your questions. They're in the links of the answers, and a tracker collects them for you. Then:

  1. Electricians and other trades in Canada: complete and maintain your HomeStars profile. Check your BBB listing, Yellow Pages and Google Business Profile. Make sure your licence details at the regulator match your business name exactly, and ask whether you can be considered for the "best of" list sites AI reads in your city.
  2. Roofers and other trades in the US: make your Angi/HomeAdvisor, BBB and Yelp profiles as strong as your Google profile. Complete your manufacturer certification listing (GAF, Owens Corning) if you have one.
  3. Professional and education services: make sure the association, the regulator and the CE listings describe your offer correctly, and that course pages say plainly what each course covers and whether it counts toward licence renewal.
  4. Everyone: use the same name, address, phone number and service list everywhere. Google's guidance on business details in Search is a good checklist. Make sure AI crawlers can reach your own site too (OpenAI's crawler documentation).

How to see your own

LLM Visibility Lens shows, for each business, every site AI read and whether those answers named you. It also shows a "sites to get listed on" list that separates directories you can join from competitors' websites you can't. You can see Kato's in the live demo. The free question finder writes the buying questions to track from your website, and plans start free. Agencies can send reports under their own name; see the agency plan.

The method is on the how it works page. There's also a comparison with Semrush's AI visibility tool, the changelog, the FAQ page and the security page. If you'd like me to look at which directories AI reads for your business, get in touch.

Questions people ask

Which directories does ChatGPT use for local businesses?

In our data, ChatGPT leaned on "best of" list sites and BBB. For a Vancouver electrician, BestProsInTown (63 answers), TrustAnalytica, ThreeBestRated and HomeStars. For a Massachusetts roofer, BBB (61), Angi, HomeAdvisor and Yelp. It also read the electrical safety regulator in 58 answers.

Does Google Maps help with AI recommendations?

Mainly in Gemini, which read Google Maps far more than any other source: 166 answers for the electrician and 135 for the roofer. But being read isn't being named: the roofer was named in 64% of those answers and the electrician in 7%, so profile strength for each area matters.

Which directories matter for dentists and lawyers?

We haven't measured patient-facing dentists or lawyers yet, and have started a study. For a dental training institute, AI read professional sources: the state dental association, the state board, an implant maker, CE Broker and university dental schools. We expect professions to mix consumer directories with official registers.

How do I find out which directories AI reads for my business?

Ask your customers' buying questions in each AI system over a couple of weeks, and note every site the answers link to and who they name. An AI visibility tracker does this daily and lists the sites, separating directories you can join from competitors' websites.

Should I pay for a premium directory listing to get into AI answers?

Not before checking whether AI reads that directory for your questions. In our data, each trade and each AI system read different directories, and some popular ones barely appeared. Fix free profiles first, and only pay where the data shows AI reads it and names businesses from it.
