When an AI engine names a local business, it is quoting something it just read. There is no hidden database of good plumbers. The engine searched, opened a few pages, and repeated what they said. So the useful question is not "how do I rank in AI" but "which pages does it open", because those are the places you need to be described accurately.
For a local business, the sources AI engines trust fall into five kinds: your own website, the map listings (Google Business Profile, Apple Business Connect, Bing Places), reviews, directories and professional profiles, and third-party mentions such as local news and community sites. The weight each engine gives them differs, and we have counted it. This post goes through the five, what we measured, and the one action to take for each.
What we measured
In October we asked three AI engines the same 40 questions a business owner in Frisco, Celina or Prosper might ask when looking for help with AI assistants, websites or automation, then counted which domains each engine cited across its 40 answers. The numbers are counts, not ranks, and they describe one trade in one month, but the pattern is clear.
- Gemini cited business websites 340 times and directories or profile sites 4 times.
- OpenAI's model (the one behind ChatGPT) cited business websites 129 times and directories twice.
- Perplexity cited business websites 537 times and directories or profiles 53 times, including LinkedIn company pages 25 times, DesignRush 8, Clutch 5 and Sortlist 4.
Two of the three engines are, in practice, reading business websites and almost nothing else. The third reads websites and a layer of profiles on top. If you take one thing from this post, take that.
Source 1: your own website
The source every engine uses, and the only one you fully control. The engines quoted pages that said, in plain text, what a business does, for whom and where. They skipped pages that said it in a slogan or an image. Two companies with no office anywhere near North Texas were named for North Texas questions because they publish a page per city, and the page was enough.
One action: put one sentence on your home page and at the top of every service page that states the service and the area, in text. Then write one page per real customer question. Our post on why AI answers name your competitor and not you explains the four ways this goes wrong.
Source 2: map listings
The Google Business Profile, Apple Business Connect and Bing Places. Engines use these to confirm that a business exists, where it is, what category it belongs to and when it is open. Google's AI answers draw on the Business Profile directly. Bing Places feeds Microsoft Copilot. Apple Maps data reaches more tools than most owners expect. A business with no profile, or three profiles that disagree, is a business an engine cannot confirm.
One action: claim all three, with the same name, phone, address, primary category, description and service list. Fill every field. Our post on Google Business Profile as an AI input goes field by field.
Source 3: reviews
Google reviews first, then Yelp, then the review sites specific to your trade (Healthgrades for doctors, Avvo for lawyers, Houzz for contractors). Engines read the text of reviews, not only the stars. A review that says "replaced our water heater in Prosper the same afternoon" tells the engine the service, the town and the speed. Thirty reviews that say "great guy" tell it almost nothing. Engines also sometimes quote reviews in the answer itself, so the words customers use become part of how you are described.
One action: ask for a review after every good job, and ask the customer to mention what you did. Reply to each one in a sentence. Steadiness over months beats a burst.
Source 4: directories and professional profiles
A LinkedIn company page, the directory for your trade, the chamber of commerce, the Better Business Bureau. In our scan this layer mattered almost entirely to Perplexity, which cited LinkedIn 25 times and agency directories dozens of times more, while the other two engines barely touched it. Your trade's directories are different from ours. The way to find them is to run your own questions and write down which sites get cited; our ten-minute test shows how.
One action: a complete LinkedIn company page and two or three trade directories, each with the same description and service list as your website. Complete beats many. Ten thin profiles are worse than three full ones.
Source 5: third-party mentions
Local news, community sites, a supplier's "find an installer" page, a sponsorship page for a youth team, a neighbourhood forum thread where someone recommends you. These are the hardest to get and, when the engine finds them, the most convincing, because you did not write them. We saw few of these in our scan for our own trade, which is itself the point: most small businesses have none, so one or two stand out.
One action: one real thing a quarter. Sponsor something and make sure the page links to you. Offer a quote to the local paper on a topic in your trade. Get on your main supplier's dealer locator. Do not buy mentions; engines are reading the same text you are, and a paid directory of "top 10 plumbers" with no reviews reads like what it is.
How the weight differs by engine
Same five sources, different emphasis, as of our October scan:
- Gemini and OpenAI: your website is almost the whole case. Listings confirm you exist. Directories barely register.
- Perplexity: your website first, then LinkedIn and trade directories as a visible second layer.
- Google's AI Overviews in Search: the Business Profile and reviews, alongside the website.
Visibility is earned per engine, which is why a check that looks at only one tool tells you less than it seems to, and why a monthly count across all three is the honest measure.
A one-afternoon plan
- Write the sentence (service plus area) and put it on the home page and every service page.
- Claim or correct Google, Apple and Bing with identical details.
- Complete the LinkedIn company page from the same text.
- Find your trade's two main directories by running five customer questions through Perplexity and noting the citations. Join them.
- Set up the review ask: a text or email after each job, with a line asking the customer to mention the service.
- Put a recurring reminder in the calendar: re-run the same five questions next month and count the mentions.
AI engines quote what they read, and for a local business they read your site, your listings, your reviews, your profiles and what others say. Be accurate in all five.
