What is eCPM - Google AdSense Knowledge
eCPM stands for: Effective Cost Per Mille (thousand impressions). Below is an explanation of eCPM from the Google Optimization Knowledge Base:
**Effective Cost Per Mille (eCPM)** is a parameter in your reports that helps you understand the profitability of your website or ad unit. eCPM refers to the estimated earnings for every 1,000 ad impressions. The impression unit can be a webpage, an ad unit, or even a single ad (you can choose this in the "Data Display Basis" dropdown menu under AdSense's "Advanced Reports"). By default, eCPM refers to the revenue per 1,000 page views.
**eCPM = Revenue / (Impressions / 1000)**
For example, if the SEO Tribe publisher earned $180 from 45,000 ad impressions on their foreign hosting site, then the eCPM would be $180 / 45, which equals $4.00.
Please note that eCPM is only a metric reflecting the profitability of your website and does not represent your actual income.
We should pay attention to the last sentence: it does not represent your income. Therefore, the more real and effective eCPM data you provide to advertisers, the more you can gain Google's trust, ensuring the long-term safe operation of your AdSense account.
