CPM = (Total Cost / Total Impressions) x 1000
If you spent $2,000 and received 800,000 impressions, the CPM is $2.50. Lower CPM is not always better, but it is a clean starting point for media efficiency analysis.
Guide
À vérifier avec le CPM
- Reach and frequency, so you know whether the same people are seeing the ad too often.
- CTR and CPC, so you can see whether cheap impressions also create clicks.
- ROAS or lead quality, so you do not scale a cheap but unprofitable audience.
