What is Prompt Market Fit?
- Prompt Market Fit
- Prompt market fit is the degree to which the questions a brand is measured and optimised against match the questions its buyers actually put to assistants. Prompt market fit is poor when a brand is named consistently for phrasings nobody uses and absent from the ones that precede a purchase, which makes it a measurement problem before it is a content problem.
01 In practice
The failure is easy to miss because the numbers look healthy. A prompt set written in a company's own vocabulary returns a strong share of answer and predicts nothing, because the questions in it are not the questions being asked.
Buyers type longer, plainer and more specific questions than keyword research suggests, and they ask in kinds rather than in variations: an open recommendation, a shortlist request, an alternatives question, a direct comparison. A prompt set covering one kind five times measures one situation five times.
Testing for fit means letting people outside the marketing team write the questions. Sales calls, support tickets and the words customers use when describing what they were looking for sit closer to the real distribution than any list assembled from search volume.
