eCPM stands for effective Cost Per Thousand Impressions (with M being the Roman
numeral for 1,000), or sometimes equivalent Cost Per Thousand (they are the same thing). This means that
it is effectively what you would have paid if you were using a CPM model.
We have provided a useful eCPM Calculator below to work out your eCPM as well as derive the number of
impressions and cost you would need to get a specific eCPM.
The Effective Cost Per Thousand Impressions (eCPM) is a metric used in
Internet advertising to calculate a publisher's expected earnings per 1,000 impressions of an
advertisement. It is widely used in contexts such as display advertising where advertisers pay for
every 1,000 ad impressions regardless of whether the viewer clicks or not.
The formula for calculating eCPM is as follows:
eCPM = (Total Earnings / Total Impressions ) × 1000
Here is a breakdown of the components.
The Effective Cost Per Thousand Impressions (eCPM) is an essential metric
in the world of online advertising for various reasons:
The effective cost per thousand impressions (eCPM) is calculated using a
simple formula that takes into account the overall earnings generated by displaying advertising as
well as the total number of ad impressions provided. Here are the steps for calculating eCPM:
Q: What impact does ad placement have in calculating eCPM?
A: Ad placement is an important aspect in determining eCPM. Ads correctly placed in high-visibility
areas often result in better engagement and as a result, higher eCPM. The position and type of ad
placements have a major impact on user interactions and conversion rates.
Q: Does the Target Audience play a part in determining eCPM?
A: Absolutely, Yes! The ad's relevancy to the targeted audience is essential. Ads that are relevant
to the targeted audience are more likely to generate better engagement, clicks and a higher eCPM.
Q: How is eCPM different from CPM in online advertising?
A: While both eCPM (Effective Cost Per Thousand Impressions) and CPM (Cost Per Thousand Impressions)
refer to the cost of one thousand ad impressions, they serve different purposes. CPM is the cost
of advertising for 1,000 impressions regardless of user activity. On the other hand, eCPM takes into
account earnings and gives a standardized statistic for comparing income across different platforms
or campaigns.
