When using the In-App SDK, you are paid based on the revenue share model, meaning that you receive a share of the revenue that Start.io makes from the advertisers whose ads appear in your app.
Advertisers pay when a user clicks on an ad or installs an app that was advertised in your app, depending on the terms of their campaign. Rates may change based on user location, device, OS platform, and version among other factors.
This means that each time a user clicks on an ad or installs an advertised app, you will earn revenue.
What is eCPM?
eCPM stands for “effective cost per mille” (‘mille’ is the Latin word for thousand, so eCPM really means “the effective cost per thousand”). In its full definition, eCPM is the effective cost per thousand ad impressions.
eCPM is used as a tool by app developers when they are comparing ad networks or evaluating the success of an ad-based monetization strategy.
What is the Formula for eCPM? How is eCPM is calculated?
Calculating eCPM is very simple. The formula for eCPM is:
Total Earnings/Impressions x 1000
(Total earnings divided by the number of impressions, multiplied by 1000)
Example for an ads revenue
Imagine that you are running two ad types in your app called “Banner 1” and “Banner 2”.
After a month or so of running the ads, you decide that it is time to evaluate the effectiveness of each ad. After reviewing the data, you see that “Banner 1” generated 345 impressions and $1.00 in earnings. “Banner 2” generated 740 impressions with $0.60 in earnings.
Based on these numbers alone, it can be difficult to determine which ad type was the most effective. This is where eCPM comes in.
After evaluating the eCPM formula for each ad type, “Banner 1” has an eCPM of $2.89, and “Banner 2” has an eCPM of $0.81. “Banner 1” wins!
One impression is counted when an ad unit is displayed to a user for at least a second.
We count impressions according to the iAB standard 1s (https://www.iab.com/wp-content/uploads/2014/10/Ad-Impression-Measurement-guideline-Global.pdf)
