Does ranking well on Google mean AI recommends you?
It helps, and it is nowhere near enough. Of the 2 best-ranked practices in Williamsport, 2 got named by an AI engine — 100%. Of the 3 ranked lowest, 2 did. The single most-named practice in this market ranked 3rd on Maps, coming up in 81% of answers.
Google rank and AI answers are decided by two different systems looking at different things. Your map position comes from how close you are, what category you are in, and how people engage with your listing. Whether an AI names you depends on whether it can find, read and trust a description of your practice in the sources it pulls from. Ranking first buys you better odds. It does not buy you the answer.
| Where they rank on Google Maps | Named by AI | Share |
|---|---|---|
| The 1st third — best ranked on Maps | 2 of 2 | 100% |
| The middle third | 2 of 2 | 100% |
| The bottom third | 2 of 3 | 66.7% |
Finding 02
How many local businesses actually appear in AI answers?
Very few, and the ones that do take most of it. Of 7 practices measured, 6 were named at least once and 1 were never named. The three most-named practices took 86% of every mention in the market.
The most-named practice came up in 81% of answers; the fourth came up in 11%; everything below that was 11% or less. A short shelf at the top, and a long floor underneath it.
Bar length is the share of all 50 answers, so a full bar would mean every answer named them.
Practice C is one organization — 3 Google Maps listings that share its website, counted once because AI engines cite the organization’s site rather than any individual listing.
Finding 03
Are the best-reviewed practices invisible to AI?
Not in this market. All 1 of the strongest practice in Williamsport were named by at least one engine.
Finding 05
Do ChatGPT, Gemini and Perplexity recommend the same practices?
No. Asked the same questions about the same market, the closest any two engines came to agreeing was 100% of thepractices they named — and the furthest apart pair agreed on just 16.7%.
Each engine surfaced a different slice of the market: Perplexity named 5, Google AI Overview named 5, Claude named 3, Gemini named 3, ChatGPT named 2. Showing up in one does not mean showing up in the others, so checking yourself against a single assistant tells you very little.
| Engine pair | Agreed on |
|---|---|
| Claude & Gemini | 100.0% |
| Perplexity & Google AI Overview | 66.7% |
| Claude & Perplexity | 60.0% |
| Claude & Google AI Overview | 60.0% |
| Gemini & Perplexity | 60.0% |

How we measured it
We pulled every Occupational Therapy practice Google Maps returns for Williamsport — 7 of them, after combining duplicate listings of the same practice — then asked 5 AI answer engines the same 10 patient questions and recorded which ones each engine named.
- Who is in it
- 7 practices, from everything Google Maps returns for "occupational therapist" in Williamsport, PA. A practice with more than one listing is counted once. 3 listings that share one organization's website are counted as that organization, because AI engines cite the organization's site rather than any individual listing.
- What we asked
- 10 questions a patient would actually ask, kept identical across ChatGPT, Claude, Gemini, Perplexity and Google's AI Overview. 50 answers in total, July 2026.
- How we scored it
- The share of answers that named or cited a practice, weighted by how many people use the engine that named it.
- How we ranked reputation
- Google Maps position, star rating adjusted for how many reviews back it up, and review count on a sliding scale that levels off around a thousand.
- Scope
- One market, one category. Every number on this page describes Williamsport and comes from that market alone — results differ between markets and we do not carry them across. We never name individual practices. AI engines change over time; this describes July 2026.
For anyone who wants the statistics
The findings above are counts, which is how most people want to read them. Here are the same relationships as correlations, for readers who prefer them.
| What we measured | How closely it tracked | What that means |
|---|---|---|
| Google Maps rank | −0.399 | A slight connection |
| Review count | +0.912 | A strong connection |
| Star rating | +0.573 | A clear connection |
Reading the middle column: 0.0 means the two things had nothing to do with each other. 1.0 would mean they moved together perfectly. A minus sign means they moved in opposite directions. Anything under about 0.2 either way is noise.
