If you are buying a local service business, you already look at the things that generate customers: the Google Business Profile, the review count, the ad account, the referral relationships. You may pull the search rankings. You almost certainly do not check how the business shows up when a customer asks ChatGPT, Claude, Perplexity, or Gemini who to hire.
That check takes a day, and it changes three things in the deal.
Why it belongs in diligence
The businesses you are buying sell to homeowners and local companies. A growing share of those buyers now start with an assistant instead of a search box, and the assistant does not return a page of ten links. It returns two or three names.
If the target is one of those names, part of what you are buying is a durable customer source that does not show up in the ad spend. If it is not, and a competitor is, you are buying a business that will quietly lose share to that competitor regardless of how well you run it after close.
Either way, you want to know before you agree on price.
What an AI visibility check tells you
A proper check runs a fixed set of the questions the target’s customers ask through the four major assistants and records three things per answer: whether the target is named, whether its website is cited, and who is named instead.
From that you get:
An answer map. How many of the 24 answers name the target. Which competitor is named most. Whether the assistants are recommending a business at all, or falling back to “try a directory.”
A site and signal score. Whether the website can be read by AI crawlers, whether it has structured data, whether the service pages answer questions or read like brochures, and whether the business’s name, address, and phone are consistent across listings.
A fix estimate. How much of the gap is on the website, how much is off it, and a rough cost and timeline to close it.
How it changes the deal
Price. A business with a strong reputation and no AI visibility is a cheap fix. The reputation already exists; the model just cannot read it. A business with neither is a rebuild. Those two situations should not be priced the same, and right now they usually are.
Plan. Day-one marketing becomes a scoped list instead of a discovery project. You know whether the first ninety days are about the website, the listings, the reviews, or all three.
Proof. The check freezes a baseline. Every month after close, the same questions get re-run and the change is measured against that baseline. That is a number you can show a lender or a partner, and it is a number you can show the next buyer when you exit.
When to run it
After the LOI and before the purchase agreement. That is the window where a finding can still change price or terms. If you are already closed, run it anyway as the baseline for whatever you do next.
The check uses only what is public: the website, the listings, the reviews, and the assistants themselves. Nothing touches the seller’s accounts, and the seller does not need to know it is happening.
For portfolio buyers
If you own or are building a group of local businesses, the check scales. The same question shapes apply across trades, and a single consolidated report covers every business. Fixing one business teaches you what to fix in the next one.
