When I create an ad for a channel, in the code it does not provide the channel ID. How can I get the ID for a channel?
I'm having the same problem. I think that the new form of managing ads doesn't expose the channel ID to us. Which is a pain because it was nice to take existing code (with all the color and formatting layout already set) and just pasted it to a new page and only update the channel ID. Now you pretty much have to go and create a brand new 'Ad'. I'm pretty sure they have their reasons for changing this...probably to get at MFAs or something. Now they have another tool for monitoring the ads an account creates. I dunno, just guessing. At any rate, I feel your pain, but don't think there's a workaround with the new system.
Adsense change code systems done. i guess channel id is slot="xxxxxxx"; from adsense code. someone else have use it?
I see ad_slot now in the code. No code for colors and the channel id. My solution is create a general ad and add your url's as urlchannel in setup.
