Frequently asked questions

How do you calculate CPM?

CPM = (cost ÷ impressions) × 1,000. A $500 campaign with 200,000 impressions is (500 ÷ 200,000) × 1,000 = $2.50 CPM.

What is a good CPM?

It varies widely by platform and audience — anywhere from a couple of dollars to $20+. Use CPM to compare campaigns and placements rather than as a fixed target.
