Frequently asked questions

CPM is the cost per thousand ad impressions. A 5,000 spend over 25,000 impressions is a CPM of 200.

Divide the spend by impressions and multiply by 1,000. The 'M' is the Roman numeral for a thousand.

CPM is common for brand-awareness campaigns, where the goal is to be seen widely rather than to drive immediate clicks.

Lower CPM means cheaper reach, but quality matters. Reaching the right audience is more valuable than simply reaching more people cheaply.
