Method and caveats
We asked web-grounded AI assistants the questions a real customer asks about plumbers in Tacoma, with no business of our own in the prompt, across 10 measurement runs. A business earns a position only after AI named it in more than one answer. An engine that failed to answer was omitted, never counted as a miss.
Caveats: AI answers vary run to run; this describes Tacoma, WA over this window, nothing more; the AI Visibility Score is a measured share of attention, not an endorsement or a guarantee of quality. Figures update as coverage grows.
