The ChatGPT Recommendation Index

We asked ChatGPT 473 real buying questions across 14 trades — the questions customers actually type — and filed every answer. Then we asked them again. This is what we found.

Ask again three weeks later and it recommends different businesses

90%

of the businesses ChatGPT names change when you ask the same question again. Across 156 questions we asked more than once, the list changed completely 77 times — 46 of those to an entirely different set of names, and 31 where it named nobody at all. It stayed the same 0 times.

Some trades are far harder to get named in than others

ChatGPT named at least one business in 88% of all asks, and when it did it named 5.7 on average. That average hides a lot:

TradeQuestions asked Named nobody Businesses named
electricians4949%4.6
dentists3923%5.4
plumbers3719%4.3

restaurants300%5.8

Ask for an electrician and ChatGPT declines to name anyone 49% of the time. Ask for a restaurant and it always names someone. Same engine, same weeks, same style of question.

What this means if you own one of these businesses

Being named once is not a position you hold. On this evidence it is closer to weather. A check tells you where you stand today; three weeks later the answer has moved.
