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, brands often request reach data as part of the briefing step so the campaign KPI is anchored against the creator’s typical performance, not against follower-count optimism.
