What is eCPM?
eCPM stands for “effective cost per thousand impressions”. It is an industry term determined by dividing revenue by impressions (in the thousands).
Divide the total number of earnings by the total number of impressions (times a thousand) to get your eCPM.
eCPM is a way to measure performance of your ad buy and to track success.
eCPM, over CPM, is a great tool to compare ad networks (even banner vs banner) when making decisions on future ad buys, design and strategy.
