Yesterday at the school campus I was curious on knowing what my earnings were at the end of the day, so I decided to go into one of the computer labs and log into my account. Today to my surprise my CPM was half the usual. I know it's was bad idea to log from the campus as perhaps some one inside the College LAN may have seen one of my websites. My questions are: Did logging from the School really affected my earnings or em I just having a bad CPM day? Will I ever go back to my usual CPM? Does Google keeps capping your earnings when they detect this behaviors? Should I contact them and ask for them to review my account?
eCPM is based on stats from people who visited your site. Logging into the AdSense admin would have no effect on the stats that happened prior to that time (nor should it have any future effect). Probably either a bad eCPM day or the stats hadn't caught up yet.
Of course if you log on to your site and examine a significant number of pages you will add to the number of impressions.
If your site has a significant number of visitors each day, your traffic will not be significant. However, if you have a lower number of genuine visitors, your own impressions could reduce the eCMP significantly.
My site usually receives about 700-800 visits per day. If I visit and examine say 140 pages and refresh some of them, (something I have done when suspecting a problem) I may double the number of impressions - and therefore halve the eCPM.
Well if you allow a small amount of paranoid thought to enter into this discussion....then since you checked your account from that IP then google has assumed you have control f that IP and have discounted clicks from that IP? This means logging in from college has discounted clicks from the college...oh my...oh my...what have you done>>:)
