eCPM (Effective Cost Per Mille)

It is a term used in online advertising. In short, it can be called the fee paid by advertising broadcasts for 1000 impressions or the fee paid by advertisers for 1000 impressions.

Its calculation is quite simple. Here is the formula;
ECPM = CPC x CTR x 1000
Effective Cost Per Mile = Cost Per Click x Click Through Rate x 1000
Effective Cost Per Thousand Impressions = Cost Per Click x Clickthrough Rate x 1000

For advertisers, most ad platforms can measure eCPM automatically. However, having a clear understanding of how to measure this metric is still beneficial. For example, a publisher may measure their average eCPM through various ad platforms.
