I have 2 ad units, and 2 link units. But I have created a bunch of channels. Is the purpose of channels, suppose to be connected to one ad unit each?
Since I only have 2 ad units, I put this in the adsense code
google_ad_channel = "#*$!#*$!x";
Is this find, or would it be better to create 1 channel per ad unit? I ask this because today I logged into my adsense, and even though I only have 4 channels and 4 units, for some reason there is a channel that reports 60k impressions when I have not added that channel's id into the google_ad_channel on any of my ads.
Also what do you guys do? Use one channel per unit or just set up one unit and use the google_ad_channel?
