How Do Companies Define Similarity Criteria for Influencers?
Quick answer
Similarity is defined by the dimensions that actually matter for a match, not by surface resemblance. Companies specify it as a mix: audience overlap, niche and topic, engagement profile, content style and size tier. Deciding which of these count, weighted by how much, is what makes a lookalike meaningful rather than superficial.
