Friends, I today found this definition of Effective CPM in Google: After reading this I became a bit confused, one of my site which is quite old and getting around 30,000 unique visitors each month is giving only around 1$ Page eCPM, while on the other hand two of my very new sites are returning around 23 to 25 $ Page eCPM. One of them which is giving 25$ eCPM is only three days old. Can you people help me to get an idea about this? Thanks in advance.
MAYBE, but not necessarily...if it is a new site, it could be that the traffic/clicks aren't high enough to give meaningful statistics. The more traffic/clicks, the more accurate the statistics are.
"one of my site which is quite old and getting around 30,000 unique visitors each month is giving only around 1$ Page eCPM" The important factor in calculating eCPM is the total earnings. So more you earn, the better the eCPM will be. I guess your old site has a low eCPM because it is not generating good earnings, and that it has a low CTR. Where your new sites may have a good CTR, which means more earnings, which means good eCPM.
Or the first has high CTR and low ePC, or the other two have low CTR and high ePC...the OP has not given enough information (and TOS prohibit giving that information) to make any accurate responses. Thus this thread is an exercise in guessing.
Hey friends, thanks for your responses. Yes it is true that I won't be able to provide all the detail, though a few detail I am providing: My old site has around 1,50,000 page impressions and around $99 earnings from last month, I mean from 1st of August. My new sites has around 2800 and 45 page impressions while $1.20 and $.10 is the earning from them respectively. One of my new domain is related to Technology and second one is a music (mp3) search engine.
The one with 45 impressions you can throw out, you don't have enough data on it for meaningful statistics. I see a 6-cent eCPM for your old site and a 43-cent eCPM for the 2800 views. Even if you calculate it for the 45 impression one, the eCPM is only $2.22 so I'm not sure where the $25 eCPM is coming from?
so if my eCPM is a dollar .... what does that mean? from my understanding that is what the publisher earns ?? not sure if i am correct here ...
No, it means that statistically (based upon your past performance) that for every 1000 page views you SHOULD earn a dollar. As the eCPM is only an estimate based upon the past performance of clicks, it is very subject to change in the future and should only be used as a rough guide. It's a way to "normalize" earnings from different sites and pages. Page1 earned $29 and Page2 earned $0.18 doesn't really tell you much if you don't know the impressions and clicks for both pages. Normalizing earnings for every 1000 pageviews allows for direct comparison of the performance of those two pages. Hope this helps.
Quick noob question, not even gonna make my own thread for it. If I have ads with eCPM and I am building my site, constantly refreshing it to see the changes, is that as bad as clicking on your own ads?? What should I do in this case?
Shouldn't be a problem but just be careful or rather cautious. You shouldn't need to be "constantly" refreshing, ie, several times per minute. If nothing else, remove the adsense from the page while you are building (replace it with a Table of those dimensions (or an image of the size of your ad) so you have blank space of the correct size) Or, turn off your javascript while checking the page (the ad will not render or be counted if your javascript is turned off in the browser) You are not supposed to cause too many artificial impressions, but even Google realizes you have to view your own pages. I usually turn JS off when I'm building, but I've refreshed my own several times over the years with no problem. I turn off Javascript more to keep my statistics "real" than because I'm worried about invalid impressions.
