What is CPM and how does CPM pricing work?
CPM stands for cost per mille - the cost per 1,000 ad impressions. An impression is counted each time your ad is served to a user. For example, if your CPM is €8, you pay €8 for every 1,000 times your ad is shown.
Why Cointraffic uses CPM
Cointraffic is a CPM-based network with a bidding model. You set a bid (your CPM) and a daily budget; the higher and more competitive your bid, the more impressions you win in your chosen GEO and format.
CPM vs CPC vs CPA
CPM - pay per 1,000 impressions (Cointraffic's model).
CPC - pay per click.
CPA - pay per action / conversion.
Cointraffic prices on impressions (CPM); you track clicks and conversions separately via S2S postbacks.
