I woke up this morning and checked my AdSense like I normally do, and I'd made way more than I was expecting. I checked the page views, and they were high. Really high. Then I went over to Analytics, and at first glance it didn't look like I'd had any more traffic overnight than usual.
So I took the AdSense reported page views for the last week, and the Analytics reported page views for the last week, and I compared them. For the last 6 days (not including today), the AdSense reported page views have been 1.34 times higher than the Analytics reported page views. So for example, if Analytics said I had 1000 page views, AdSense would say I had 1340.
