I just tried to organize my adsense info, which has been built using a mix of custom and url channels. I basically deleted all the URL channels and then built new ones so I could track my revenue and data by domain and by section of the domain. I now have a few days of data and I can't make sense of it. Questions: - Is there a difference between entering a domain in adsense as: www.test.com vs test.com? - On custom channels, if there are two ads on a page both listed in the channel, will one page impression count as one or two impressions? - Is there any tool for tracking to find out on which page the custom channels have been placed? I'd appreciate any help.
