The questions

Asked word for word, three times each, to every assistant. The prompt is the one the free scan uses. No web search, no location and no chat history, so every answer starts from the same place.

  1. 1Who is the best plumber in Manchester?
  2. 2I have a leaking pipe at home in Manchester. Which plumbing company should I call?
  3. 3I need an emergency plumber in Manchester tonight. Who would you recommend?
  4. 4Which plumber in Manchester would you trust to fit a new boiler?

On this page the same questions were also asked with web search on, 1 answers. 0% of the businesses named with search were also named without it; the With search column above is each business's share of those answers.

How to read this page

The full method
What it measures
Which names these models produce when asked cold, from what they learned in training. It is not a review, a rating or our recommendation, and a business missing here may simply be one the models were never shown.
Why the ranges matter
48 answers is a sample. Asked again next month, most shares will move by a few points; the ranges say how far they could move by chance alone.
One business, several spellings
Branches, legal suffixes and spellings of one business are merged, and the other spellings are printed under its name. Names that might be two businesses are kept apart.
A name is wrong
If a business here is closed, misnamed or yours and you want it removed, tell us. We correct or remove it when the page is next published.
