I know this may sound ridiculous, but I have forgotten where I place a particular adsense code on a website. Is it possible to trace back the page from the channel?
check the source code of your ad.. it has a date... also check "manage ads" inside your adsense account..
If I understand you correctly - look for your channel id in your adsense account (adsense setup/channels) and search for this id in your code.
What happen was I changed my host and I change the entire website. And I used another channel name to track the new adsense. But I am still getting earnings from the old channels and yesterday it registered one click for $9. So I am very curious where the ads are. I could have set up some blogs which I have forgotten. Thanks for the replies.
