On my website, I ran an adwords campaign in the first quarter of this year and since April have stopped all campaigns but in Google Analytics I keep seeing referrals from doubleclick/google. What is going on? My credit card has not been charged and I see no activity in my Adwords account.
The only possibility is that someone else is running a campaign and sending traffic my way. Who could be so generous?
We can't even imagine what kind of automated websites are out there, including scrapers which possibly are still showing your ads somewhere as they're hard coded or simply the site/page is not being updated.
