As Google acquired double click back in 2007 they started to integrate it into their systems. Some of the ads on the adwords platform are now being served from doubleclick systems hence you see that URL as a referrer. Note this will mostly reflect traffic from the content network and placement targeting campaigns.
cobra, no, we, or I, have no problem with it so far. just when I tried to click, nothing will happen. It is like no 广告, so you don't have to close them, of course it doesn't do ht any good either.
