Cost per engagement
Spend divided by likes, comments, saves and shares received. Cost per engagement measures what each interaction cost after the fact. It is the cleanest post-campaign comparison across creators of different sizes.
Why it matters
It tells you who to rebook. The creator with the lowest cost per engagement is usually not the biggest one.
Formula
CPE = spend ÷ (likes + comments [+ saves + shares])
How Zaver measures it
With post metrics refreshed into a sheet, CPE is one formula over the Deliverables tab.
