Disclosure: RehabAdmit is a rehab marketing agency and appears in this data. We counted every agency with the same rules, including ours, and the method below explains them. Nothing here is a ranking of agency quality: it records what AI assistants said.
What gets a rehab marketing agency recommended by AI?
Three kinds of pages put an agency into AI answers: best-of lists, the agency's own service pages and, for ChatGPT, directory profiles such as Clutch. Here is what the 1,188 cited sources show.
- Best-of lists. Lists and comparison pages made up 399 of the 1,188 citations, and 113 of the 167 answers that cited sources used at least one. One list can put several agencies into an answer at once.
- The agency's own site. Agency homepages and service pages were the largest group, at 635 citations. healthcaresuccess.com was cited in 53 answers, more than any other website.
- Directory profiles, for ChatGPT. ChatGPT cited directories and company profiles 69 times; Gemini cited them 4 times. Clutch was ChatGPT's second most cited website, in 18 of its answers.
- Each assistant reads differently. Perplexity cited 10.0 sources per answer, Gemini 7.9 and ChatGPT 3.7. Gemini kept returning to the same large firms; ChatGPT spread its picks wider.
Our read: an agency that wants to appear in AI answers needs to be on the lists AI already cites, with clear service pages and a complete directory profile behind them. The rest of this study shows the detail.

How did RehabAdmit go from 1 to 10 AI mentions in four weeks?
RehabAdmit was named in 1 answer on September 30, 5 on October 22 and 10 on October 28. Here is what we did in between, and what the answers that named us cited. We can't prove which step moved the number, but the cited sources point at two of them.
- Before September 30: our agency comparison page and seven head-to-head pages were live. The one answer that named us on September 30 cited the comparison page.
- October 6: we published eight agency review pages.
- October 8: we published a LinkedIn article and cross-posted it to Medium. None of the answers that named us cited either one.
- By October 20: our profiles on Clutch and Agency Spotter were live.
- October 22: 5 answers named us, all from ChatGPT. 2 cited our new Clutch profile and 2 cited the comparison page.
- October 24: we published seven best-of lists by service line and five more agency reviews.
- October 28: 10 answers named us, 9 from ChatGPT and 1 from Perplexity. 5 cited our Clutch profile and 2 cited our new behavioral health agencies list.
Gemini has not named us yet. It cites directories far less than ChatGPT does, which fits the pattern above.
How should a treatment center use this?
Use AI answers as a starting shortlist, not a verdict: they reflect what is published about an agency, not audited results. Then compare pricing, contract terms and reporting on each agency's own site, as we do in rehab marketing agencies compared, and ask each one for cost per VOB and cost per admission reporting (see how much rehab marketing costs).
The same mechanics decide which treatment centers AI recommends to families: lists, directory profiles and clear program pages. We can check yours and show which sources AI uses when it answers questions about your programs.
How was this study built?
- Assistants and models: ChatGPT (gpt-5.4-mini), Gemini (gemini-3.8-flash) and Perplexity (sonar), each with web search on, queried through the DataForSEO LLM Responses API.
- Dates: September 30, October 22 and October 28, 2026, with the same questions and models each time. Two Gemini answers on September 30 failed, which leaves 184 answers.
- Questions: 26 for ChatGPT and Gemini (20 questions plus 6 title-case versions of the same buyer queries) and 10 of them for Perplexity.
- Counting agencies: an agency counts once per answer when the answer text names it, matched against a tracked list of rehab and healthcare marketing agencies. Agencies not on the list are not counted.
- Counting sources: each cited link counts once per answer. Page types come from the link: regulator and government sites first, then list and comparison pages (URLs with words like best, top, agencies or compared), then directories and company profiles, then forums and social, and everything else as agency pages.
