Selecting influencers by campaign type, not one fixed checklist
Quick answer
The factors that matter depend on what the campaign is for and using one fixed checklist is the mistake. An awareness campaign wants reach and a creator who makes shareable content. A conversion campaign wants a trusted, high-intent audience even if it is small. A launch wants credibility and timing. So before listing factors, name the campaign goal, then weight reach, trust, niche fit and engagement accordingly. The same creator can be a great pick for one campaign and a poor one for another, which is why the goal has to come before the criteria.
I keep using the same influencer selection criteria for every campaign and the results are inconsistent. What factors should I consider when selecting influencers for my campaign and why does the same checklist not seem to work every time?
