Using eCPM to gauge Project Wonderful
In talking about ADSDAQ a while back, we came across eCPM as a unit of measure. In researching the topic, I've found that it's a pretty useful tool for comparing how your ads are doing.
eCPM stands for "effective cost per thousand impressions." ADSDAQ uses it, and so does Google AdSense.
eCPM is calculated by dividing total earnings by total number of impressions and then multiplying by one thousand.
It's used to compare how two different ad campaigns are doing, but I think it could have a distinct use for those of us who use Project Wonderful.
