I have impressions showing, but I have no idea where they are coming from. I had put the same advertiser on various web pages. Then, I decided to remove the advertiser, and I removed all the code, I THOUGHT! Is there any way to find out which page is still showing the impressions? I want to remove the code from the "Mystery Page". Thanks for your help.
Without asking CJ (and I'm not sure if they even store the referring URL information for impressions), there's no way to find out. I do know that CJ stores referrer information for clicks, though.
tvmatt - Thanks. That's what I was afraid of. I guess that this is a good argument for keeping better records. After I leave CJ this month, a year from now, I will finally stumble upon the right page. Now if I could just find out where my YPN impressions are coming from, that have a blank "Category" (channel name). Ha-ha.
