adsense.blogspot.com/2006/02/ecpm-what-exactly-is-that.html eCPM is a bit of industry shorthand that seems here to stay. eCPM is calculated by dividing total earnings by total number of impressions in thousands. It is a great performance measure for your various ad units, so when experimenting, you can use eCPM to compare your results. But what if your site doesn't receive enough impressions to have a large sample size? Even for smaller sites, eCPM can be a useful statistic to track ad performance. custom channels named 'Blue Skyscrapers' and 'Red Rectangles', respectively, which reflect the types of ad formats we're testing on our site. To make these figures more comparable we calculate eCPM -- ie, the estimated earnings for every 1,000 impressions received. |
