Someone somewhere is wasting his or her ad budget. I am seeing a steady stream of "Your Ad Here" ads on my site. They are obviously templates supplied to AdWords advertisers and include such catch phrases as "YourURLHere."
They have been showing up with some regularity in graphic formats 300x250 and 160x600. I have to assume that some poor soul has saved an incomplete template and attached a bid to it, as our overall CPM, CPC, etc., are all normal or slightly above normal.
They look like hell, I must say. They're about as attractive as the old "under construction" graphics everyone was using ten years ago.
