Frequently asked questions
What is CPM in advertising?
Cost per mille: what you pay for 1,000 impressions, or times your ad is shown. It measures reach cost, not clicks or sales.
Is a low CPM always better?
Not always. A cheap CPM with the wrong audience can bring no sales. Look at CPM together with clicks, conversions and return on ad spend.
