The short answer
Prompt market fit is the match between the questions your buyers really ask AI assistants and the pages, proof and positioning your brand offers in reply. A gap means the assistant has nothing good to quote from you.

Why Prompt Market Fit matters
You can have strong pages that answer questions nobody asks. Fit is about answering the questions that lead to a sale.
How to measure or use it
Write down the real questions from sales calls, support tickets and search data, then check which ones have a clear page on your site.
How I handle it
I build the question list from your sales and support conversations first, and from keyword tools second.
