Why Convert CPM to CPC?

Converting CPM (Cost Per Mille) to CPC (Cost Per Click) helps you compare different advertising pricing models. It allows you to estimate how much you are effectively paying for each click when buying impressions, or vice versa. This is crucial for optimizing campaigns across platforms that use different bidding strategies.

The Conversion Formula

The formula to convert CPM to CPC is:

CPC = CPM / (CTR × 1000)

Note: CTR should be a decimal (e.g., 0.01 for 1%). If using percentage (e.g., 1), divide by 100 first.
