Inside my Google Adsense account, the amount of total page impressions I see under Report Overview is 3,932. However, when I click 'Top Channels' to see the breakdown for each URL/domain I see only 1090 page impressions. The problem is, I only have one domain. In fact, this is the only domain I have ever used with this Adsense account. My CTR is also different in each case. Lower in the first. Higher in the second by about 6%. Note: The page impressions are from "All time" for the Report Overview AND channels breakdown. Could anyone tell me what's going on here....
I have bitched about this in other threads. I am having the same problem. Nothing is adding up for me lately. Clicks, earnings, etc. I contacted Google but I doubt I will ever hear back. Really sucks.
I think I've finally realized what the problem is. The 1090 page impressions are only for that specific URL, the homepage. A domain has many URLs however - for example, a URL for each page, each blog post, etc. The lower number of page impressions under the 'channels' tab is due to the fact that I haven't added each and every one of those URLs/pages/channels to the Channels list.
