Reach

The number of unique users who saw a piece of content at least once during the measurement period.

Brands optimise for reach when the campaign goal is awareness — launching a new product, entering a new market, or repositioning a brand. For conversion campaigns, engagement rate and click-throughs matter more than raw reach.

On Collabios, the brief a brand writes at checkout is the natural place to ask for the creator’s recent reach figures, so the campaign KPI is anchored against the creator’s typical performance, not against follower-count optimism.
