Can I judge an influencer's audience engagement from their past campaigns?
Quick answer
Past campaigns are a useful window, read with care. Look at how a creator's sponsored posts performed against their organic ones, since a big gap can mean the audience tunes out ads. Comments that sound like real people matter more than the like count. Treat it as one signal among several rather than proof.
Whether an influencer's earlier brand work is a reliable guide to how engaged their audience really is.
