GLOSSARY
CPM (Cost Per Mille)
What is CPM?
DefinitionCPM is the cost to serve 1,000 ad impressions. It reflects auction competition and audience value. Industry benchmark data puts health/medical Meta CPMs around $13, and supplement CPMs higher at ~$18 - both inflating year over year.
Formula
CPM = (Ad spend ÷ Impressions) × 1,000CPM is a read on auction competition and creative quality, not a bid to force down. Across AdBoost Health partner accounts, creative fatigue shows up in CPM and hook rate before it ever reaches ROAS: a GLP-1 account whose CPM climbs from $14 to $22 on a stable audience is watching its creative stop earning delivery, and the fix is fresh angles at the standard 15–25 variants per month, not a lower bid. Health CPMs also spike in Q4 and around open enrollment, so judge CPM against your own trailing baseline, and read it next to CPC to separate reach cost from click cost.
