The ratio of revenue generated by a campaign to the campaign’s total cost.
Industry benchmark in 2026 puts well-run micro-influencer campaigns at 3-5x ROI on direct attribution and significantly higher when brand-lift is included. Macro/celebrity-tier campaigns trend lower on direct ROI but contribute more to brand-awareness goals.
Collabios doesn’t mediate post-campaign analytics — brands track ROI in their own attribution stack. The marketplace surfaces what brands need at booking time (transparent fees, deliverables, creator authority signals) so the inputs to the ROI calculation aren’t a black box.
