How many local businesses actually appear in AI answers?
Very few, and the ones that do take most of it. Of 5 practices measured, 3 were named at least once and 2 were never named. The three most-named practices took 100% of every mention in the market.
Bar length is the share of all 50 answers, so a full bar would mean every answer named them.
Finding 03
Are the best-reviewed practices invisible to AI?
Not in this market. All 1 of the strongest practice in Lake Charles 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 33.3%.
Each engine surfaced a different slice of the market: Claude named 3, Gemini named 3, Perplexity named 3, ChatGPT named 2, Google AI Overview 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.

How we measured it
We pulled every Vein & Vascular Treatment practice Google Maps returns for Lake Charles — 5 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
- 5 practices, from everything Google Maps returns for "vein clinic" in Lake Charles, LA. A practice with more than one listing is counted once.
- 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 Lake Charles 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 | −0.879 | A strong connection |
| Review count | +0.008 | No connection |
| Star rating | +0.995 | A strong 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.
