Five studies I ran myself, published August to September 2026.

94%

of Houston’s roughly 50,000 Realtors were never named in 2,000 AI answers.

One dot is 50 Realtors. A lit dot is 50 who were named at least once in the 2,000 answers; the rest were never named.

In September 2026 I put 500 Houston real estate questions to four AI surfaces and hand-checked every agent, team and brokerage they named. Of the agents that were named, 82.6% appeared in just one of 40 areas.

The Houston study, published 23 September 2026.
