I got several sites and on each site are several channels. These are not URL channels, but custom channels. Recently there have been clicks that show in summary data, but not in any channel data. I am guessing that either someone is using my pub-id or I screwed up setting up an add somewhere and the channel code was missing. Does anyone have any suggestions on finding the culprit?
You probably screwed up, same thing happened to me. If it's just one site you could always re-do it. i'm too lazy to. But who would be so kind to use your code?
If you feel someone might be using your pub.. you might want to restrict the use of your pub in a list of your own URLs in your adsense account. If the code on the scrapped sites is broken, that might account for it. I'm surprised a scrapper would let your pub id continue though.. they are usually good at changing those first Let us know when you figure out what was behind it all.
