CPM is your cost per 1,000 impressions — the price of attention on the platform's auction. Targeting and seasonality set the baseline, but creative moves it more than most buyers expect: platforms reward ads people watch (higher hook rate → cheaper delivery) and punish ads people skip. That makes CPM a fast, cheap testing signal — in a 24-hour angle test, relative CPM between variants tells you which creative the algorithm favors before conversions accumulate.
Why creative changes CPM
Auction systems optimize watch-time and engagement; an ad that holds viewers is cheaper to serve. Creative fatigue works the same in reverse — rising CPM on a stable campaign usually means the ad wore out.
Using CPM in fast validation
Run 3 variants at small spend; a variant with meaningfully lower CPM + higher hook rate is the algorithm's early vote. Confirm with conversion data before scaling.

FAQs
What's a normal CPM?
Wildly variable by geo, audience and season — $5–$30+ on Meta/TikTok. Compare variants against each other, not against global averages.
High CPM — kill the ad?
First check frequency and fatigue; refresh creative before rebuilding the campaign.
