I read that this is could be a common issue? In this adsense account I have multiple sites. For the past 4 months there has been a huge discrepancy between adsense stats and analytics stats. Then last Friday I moved a new site to this adsense account and up until yesterday the stats from adsense and analytics where pretty darn close. Then today the same issue is happening like it is with the other sites in this account. For example right now the page views on the site in analytics shows 12,000, in adsense for the same site it shows only 3000 page views. I mean thats a big difference. I checked the coverage and its at 99%. Any suggestions on what it could be? What to look at to get a better idea on whats going on?
