How AI assistants appear to choose which businesses to name

How AI assistants choose which sources to cite

Here is what is documented. Each assistant runs a search in an index it has named publicly, retrieves a set of pages, and writes an answer from them. ChatGPT and Copilot read Bing, Gemini reads Google, Perplexity reads its own index with Bing behind it.

How the assistant decides which of those pages to quote, and which businesses inside them to name, has not been published by OpenAI, Google, Microsoft or Perplexity. So the only honest way to talk about it is by observation. When you run the same prompt forty times and log which sources appear, patterns show up. The patterns are consistent enough to act on, and anyone promising a guaranteed placement is selling something they cannot deliver.

In our testing, four things come up again and again in the pages that get quoted: the page answers the specific question in a sentence that stands on its own, the business has the same name and category everywhere the assistant looked, the business is mentioned on pages it does not control, and the page carries a recent date. Each of those has its own page in this guide, starting with entity clarity.

What being skipped by AI assistants looks like for a med spa

Sawtooth Skin and Laser is a med spa in Meridian with two nurse injectors, a physician medical director, and an average treatment package of $1,200. It does Botox, dermal filler, Morpheus8, laser hair removal and IPL. It ranks on the first page of Google for med spa Meridian Idaho.

A prospective patient asks Perplexity: Which med spa in Meridian Idaho does Morpheus8 and what does a package cost? Perplexity names two competitors and a chain with a location in Boise. Its sources are a Boise lifestyle magazine’s roundup, a RealSelf listing, two competitor service pages and a Reddit thread. Sawtooth is not cited and not named.

Looking at why, the pattern is clear. The Morpheus8 page on the Sawtooth site is 90 words long, says the treatment tightens skin and that results vary, and has no price, no session count and no mention of Meridian. The magazine roundup that Perplexity leaned on was written in 2024 and lists eight med spas, none of them Sawtooth, because Sawtooth opened in 2025. The Google Business Profile category reads Skin Care Clinic while the site says Med Spa.

A worked example: forty prompts against a Meridian med spa

The owner ran ten prompts in each of four assistants, forty runs in total, and logged every source cited and every business named. The prompts covered Morpheus8, lip filler, laser hair removal, Botox and a general best-med-spa question. Here is what was cited most often before any changes.

Over the following two months the Morpheus8 page was rewritten to 600 words stating the price range, the number of sessions, the recovery time and the Meridian address in plain sentences. The Google category was changed to Medical Spa to match the site. The owner asked two Meridian clients who write for local publications to include the spa in their next roundup, and claimed and completed the RealSelf and Yelp listings with matching details. Then the forty runs were repeated.

Sawtooth went from being named in 3 of 40 runs to 29 of 40. The rewritten page did most of the work on the Morpheus8 and pricing prompts. The magazine update did most of the work on the general best-med-spa prompt, which is the pattern covered under third-party mentions. No single change moved every prompt, and the general recommendation question depended on other people’s pages more than the spa’s own.

How to check your own sources across the four assistants

1. Write ten questions your customers ask, in their words, with your town in them. Include two general ones such as best med spa in Meridian and six specific ones about a treatment or a price.
2. Run each question in ChatGPT with search on, Gemini, Copilot and Perplexity, using a fresh chat for each. That is forty runs.
3. For each run, record the businesses named, in order, and every source the assistant cites. Perplexity shows numbered sources under the answer, Copilot shows them as footnotes, ChatGPT and Gemini show source links you can expand.
4. Count how many times each source appears. The sources at the top of that list are the pages the assistants are relying on for your trade in your town. Open each one and check whether you are on it, and whether what it says about you is right.
5. Open your own page for the most-asked treatment and read it as the assistant would. If it does not say a price range, a duration, a location and who performs the treatment, in complete sentences, it will be read and skipped.
6. Save the log and run it again in a month. The change in how often you are named is the only measurement of mentions that exists.

What we do about how assistants choose sources

You will get the forty-run log for your business, showing which sources the four assistants rely on for your trade in your town and how often you are named today. The pages the assistants are quoting instead of yours are listed. Your own service pages are then rewritten so each states the facts an assistant needs in sentences it can lift, and the outside listings that feed the answers are claimed and corrected. The log is run again every month so you can see the count move. This is part of every site audit, which is where the work starts.
