Questions
Does this mean these plumbers are the best?
No. It measures what AI assistants say, not service quality. AI answers can be incomplete or outdated.
Why do the results change from one answer to the next?
AI assistants do not give the same answer every time. That is why we sample each question several times and report confidence intervals.
How can a business appear more often?
The answers rely on the sources listed above: being present and well reviewed there is a good start. See the methodology.
