CTR = Click thru rate = the percentage of pageviews the result in a click on your ad units. eCPM = Estimated earnings from 1000 pageviews.
Ctr and Ecpm are related. The higher Ctr the higher Ecpm usually. Country boy explained it exactly . Ctr example would be 10%. That mean 10 clicks per 100 page views. Ecpm means you would make so much money for every 1000 page views of your website at that CTR.
CTR = click through rate The percentage of people who click your ads. For example, if your ad is displayed 100 times, and 3 people click it - your CTR would be 3%. (The higher the CRT the better) earnings (or effective cpm), like Country Boy explained. Basically this means the dollar amount you earn per thousand ad displays/impressions - on average. If your page loads 3000 times one ad, and you have eCPM is $4.00 that means you are earning $12 (1000 x eCPM or 1000 x $4.00). With $4 eCPM and 10,000 displays - you would be earning $40.
CTR is the number of times an ad has appeared on a web page (number of impressions) divided by the number of times it has been clicked on. In simple terms this means how relevant or good your ad is performing. Higher CTR means your ad is doing good as more people are clicking on it. Whilst on the contrary, a lower CTRY would mean that the ad is not performing well, as people are seeing the ad but it does not influence them enough to click on it.
