How to read this, and what it does not say
- This is not a ranking. Being named means an assistant said your name out loud when a buyer asked. It is a visibility measurement, not a judgement about which dentist is better.
- It is one snapshot. Collected 2026-08-15/16 on the models of that week. Generative answers move, so a business missing here may be named today and the reverse is just as true.
- The denominator is capped. Google Maps was queried at depth 100, so the real Portland, OR market is at least 100 dentists and possibly larger. The share is therefore an upper bound.
- Strict name matching. A looser matcher, the one the product itself uses against a single business, would put this market at 31 businesses (31.0%) instead of 10. Both are published; the strict figure is the headline because the loose one inflates counts across a full roster.
