Audience: name the person and the situation
Not a persona document with stock photos. One page that says who runs into the problem, what they are doing when it happens, what they have already tried, and who signs the purchase. Three named situations beat twenty demographic attributes.
For an industrial supplier this might be a maintenance lead whose line stopped on a Friday, a procurement officer comparing two compatible parts, and an engineer specifying a replacement for a discontinued model. Each one searches differently, and each needs a different page.
