I post and promote my site a lot through Facebook and I've done it for over a year and have never had a problem, but as of the last few days I've noticed a lot of my page views have not been accounted for through Adsense. I'm wondering is it because the traffic is coming from Facebook? I've never had a problem directing traffic to my site in the past. If anyone has dealt with this or knows why a lot of my page views aren't being accounted for, please help. Any advice on this topic would be much appreciated. Thanks.
