I think I really have problem with adsense stat.
I use one domain name to register adsense, since then, I have set up URL channels 3 days ago.
According to my record of all of my other domain names, the average daily stat is 20 visitors per site per day.
All of them were set up by wordpress, except the one I used to register adsense.
Today, I checked my adsense stat, I found only the domain name I registered adsense has adsense impressions, and all other sites don't have any adsense impressions, what happen to my other sites? I use the same adsense code to put on all my sites, but only one site has adsense impressions.
