How Important Are Influencers' Past Campaign Performances When Shortlisting?
Quick answer
Past campaign performance is a useful shortlisting signal but only partly visible. Exact results from previous brand deals are usually private so you judge from what you can see: consistent engagement, content quality and how sponsored posts landed. Treat the observable track record as evidence, not a guarantee of future results.
