**What is eCPM - Google AdSense Knowledge**
eCPM stands for **Effective Cost Per Thousand Impressions**. Below is the explanation of eCPM from Google's optimization knowledge base:
The **Effective Cost Per Thousand Impressions (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 impressions. The units of display can be web pages, ad units, or even individual ads (you can select this in the "Data Display Basis" dropdown menu under "Advanced Reporting" in AdSense). By default, eCPM refers to the revenue per 1,000 page views (Pageview).
**eCPM = Revenue / (Impressions / 1000)**
For example, if the publisher of SEO Tribe 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 parameter reflecting the profitability of your website and does not represent your actual income.
It’s important to pay attention to the last sentence: **it does not represent your income**. Therefore, the more real and effective the eCPM you provide to advertisers, the more you can gain Google's trust, ensuring the long-term safety and stability of your AdSense account.
