Cost Per Engagement (CPE)
The amount an advertiser pays for each like, comment, share, or save on influencer content.
Cost per engagement, or CPE, is total spend divided by the number of engagements a piece of content earns, such as likes, comments, shares, and saves. It tells you what you paid for each meaningful interaction rather than each passive view, making it a more demanding efficiency metric than CPM. A creator with a smaller but highly engaged audience often delivers a lower CPE than a large account with passive followers. CPE is especially useful for comparing micro-influencers against macro creators, because raw reach can hide how little an audience actually responds.
Gigde uses CPE to separate creators who command genuine attention from those who merely have large follower counts, which informs roster selection in Influencer Marketing. We model expected CPE before booking, then verify it against real post performance so you reward creators whose audiences act. For clients running Influencer Campaign Management, we shift budget toward low-CPE partners while watching that engagement quality stays high, not just cheap.
