It goes on for quite a bit. Only happened yesterday. I use adsense but not adwords. What would you make of this? I recorded double the visitors to my site but only a slight increase in page views. Unique visitors were almost doubled too. What's going on??

I examined a few sites that you can pull out of the referrer part and they all seem to have google adsense ads on them.  It's almost as if my website was displaying in some adsense ads, except I don't use adwords and all the traffic with the googlesyndication referrer is coming from the same google IP address.
