I know I might sound like a complete idiot here, but until now I really haven't noticed that my Adsense earnings are slowly dropping downhill and I actually looked at my CTR and Page eCPM and went "What the heck are these and why are they so low. To keep inside the Big G's ToS, I'm not going to name full numbers, but I'll tell you my CTR, tends to either be at %.09 being the lowest, and somewhere around %1.2 at the highest. These values seem really small, and I was wondering what they are and how I can raise them. Secondly, moving onto Page eCPM... now I believe this runs along the lines of "Cost per thousand impressions" and even if I have that definition right, maybe someone could help me with what the heck that means... and how it affects my earnings and how I can raise it! I know this might sound all stupid, but I appreciate your help and will be adding rep for useful answers. Cheers, Ben
CTR represents the Click Through Rate. It is represented by the number of people that click on the ad compared to the number of impressions the ad offers. You always raise adsense by adding more traffic to your website and having the best locations for the ads. Ecpm represents how much you earn for 1000 impressions. So in a way you raise it buy getting more clicks on your impressions.
ctr meaning CTR is click-through-rate. If the impression is 1000 and you get 10clicks, that means your CTR is 1%. eCPM is effective cost per thousand. That means, if you have 2000 page impressions and your clicks earned you $10, your eCPM would be $5. That is your earning for every thousand impressions. So, to sum them all up, lets take this example: You have 10,000 page impressions and 200 clicks and earned $300. Your CTR is 200/10,000 * 100% = 2% Your eCPM is $300/10,000 * 1000 = $30
