Something I never noticed before is that you can have multiple channels for a single ad group.
I don’t know how long this has been active, but I haven’t generated new AdSense code in a while.
I actually went in to check something out in the AdSense control panel because someone on DigitalPoint had mentioned a google_ad_host = “” variable and I wanted to check it out. But alas, it didn’t show up in my account.
