Hi, I have two sites in the same niche. First site have 1.5K visitors per day, second have 300 visitors per day only. But in my adsense stats both sites have the same count of page impressions. Why? I though second site musy have less (at least in 5 times) page impressions, right? Any ideas?
Or could it be "ad unit" impressions you are talking about (instead of page impressions)? Maybe your second site has 3 times more ad units per page than your first site?
