Frequently Asked Questions
Frequently asked questions about the CPM Calculator
When should I use CPM instead of CPC?+
CPM is most useful for brand awareness campaigns where the goal is reach and visibility rather than direct clicks or conversions.
What is a typical CPM?+
CPM varies enormously by platform, audience and season — from under $1 to well over $30. Compare your CPM against your own historical campaigns for the most meaningful benchmark.
How does CPM relate to CTR?+
CPM measures the cost of reach, while CTR measures how many of those impressions turned into clicks. A low CPM with a low CTR can still be an expensive way to get clicks — check both together.
