### What is eCPM (Effective Cost Per Mille)?

eCPM is a metric used in digital advertising, typically within the world of monetizing mobile apps. eCPM is used to measure how much an advertiser pays an app publisher for an ad space per unit of 1,000 ad impressions. What's the word millie you ask? Millie is Latin for thousand!

### ECPM Floor

The ECPM Floor refers to the minimum cost per thousand impressions (CPM) set by a publisher for advertising on their website. If an advertiser's bid falls below this floor, their ads won't be displayed. The winning bidder is usually the one who offers \$0.01 more per thousand impressions (eCPM) than the floor price. However, if no bids meet the publisher's baseline, they may incur a financial loss.

Minimum eCPM floors can be set at different levels, including by country, platform, advertiser, and ad unit. It's important for the advertising operations team to regularly monitor the impact of these floor prices on revenue, as improper settings may result in losses.

eCPM (effective cost per thousand impressions) is a valuable metric for app developers, as it allows them to compare ad revenue across various factors such as ad network, operating system, location, and more. For example, if you want to determine which ad unit is the most profitable, you can calculate the eCPM of each and compare the results.

Suppose you find that a rewarded video generated \$5.00 in revenue after 400 impressions, while banner ads generated \$3.00 after 700 impressions in the same time frame. Based solely on these metrics, it is difficult to make an informed conclusion about the relative performance of the two ad units.

However, when you calculate the eCPM, you see that the eCPM for banner ads is \$4.29, while the eCPM for rewarded video is \$12.50. This makes it clear that rewarded video is a more profitable business model for your company.

### CPM vs eCPM? What's the Difference?
