In plain English
Meta reports it against whichever result you chose to optimise for. Choose link clicks and you get a cost per click; choose purchases and you get a cost per purchase.
The figure is only as useful as the result behind it. Optimising toward a cheap event produces an impressive number and no revenue.
What to know
Spend over the chosen result
Whatever you optimised for.
Definition decides it
Cheap events give flattering numbers.
Compare against value
What a result is worth to you.
Not incremental
Platform-attributed, not proven causation.
Why it matters
The comparison that matters is cost per result against what a result is worth, calculated from your own margin. Any other benchmark is somebody else's business.
Common mistakes
×Optimising toward a cheap proxy event.
×Comparing cost per result across different optimisation events.
×No calculation of what a result is worth.
×Treating platform-reported results as fully incremental.
