In digital advertising, understanding performance metrics is crucial for content publishers and there are several metrics that publishers can track to measure the effectiveness of their campaigns. One of such metrics is the eCPM.
What is eCPM and How is it Different from CPM?
eCPM stands for effective cost per mille and is not one and the same as CPM, which stands for cost per mille. In simple terms, while CPM basically calculates how much an advertiser pays per 1,000 impressions, eCPM calculates how much a publisher earns per 1,000 impressions.
CPM is a common pricing model used in digital advertising where advertisers pay a set rate for a thousand views of their ad, regardless of clicks or other interactions.
Unlike CPM, eCPM takes into account the actual revenue generated rather than just the cost. It helps publishers gauge the effectiveness and profitability of their ad inventory.
In essence, while CPM and eCPM both involve the cost and revenue associated with ad impressions, they serve different purposes and are used by advertisers and publishers respectively in the digital advertising ecosystem.
By calculating eCPM, publishers can assess which ad placements, formats, or targeting strategies yield the highest returns. This enables them to make informed decisions to optimize their ad inventory for better monetization.

Calculating eCPM in 3 Simple Steps
Calculating eCPM typically involves three simple steps. Following these three steps will give the publisher a clear understanding of their eCPM, helping them optimize their advertising strategies and maximize revenue.
1. Measure The Ad Revenue
Publishers calculate their total ad revenue by multiplying the revenue earned per ad unit by the number of total ad units sold. For example, if the publisher sells 200 ad units at $3 per unit, this means the total revenue is $600.
2. Divide Revenue by Impressions
Assuming that the total impressions for the month is 150,000, the publisher will then divide the total revenue by the total impressions. Dividing $600 by 150,000 equals $0.004.
3. Multiply Outcome by 1,000
The revenue per impression is then multiplied by 1,000. In this example, $0.004 multiplied by 1,000 gives the publisher $4.
Factors That May Affect eCPM
There are a number of factors that may affect eCPM and how much a publisher earns from ad campaigns. Here are some of them:
Ad Format
Various types of ads make different amounts of money for publishers. For example, video ads usually make more money than regular banner ads. This means they cost more for advertisers but bring in more profit for publishers.
Ad Quality
Good ads, like creative and memorable videos with clear pictures, usually grab people’s attention more. They’re more interesting and engaging. These kinds of ads often make more money for publishers compared to basic or low-quality ones.
Ad Placement
Publishers should also think about where they put ads on their websites or apps. Ads that are easy to see often make more money. For example, placing ads at the top of a page or using pop-ups can bring in more income.
