I have ads on 10 different sites. But don't have any channels except from my first site. What does that mean? am i only recieving revenue from the adds on one site?
No, you'll still be receiving revenue from all of the sites. Channels are just a way for you to keep track of how much you get from each site (or ad). Let's say you have 10 domains as an example. If you set up a channel for each domain then your reports will show how much each domain returns.
Few, yes i thought that was weird. But im so excited anyway. I set up two financial blogs today. And bang 9 clicks, for $5.50 . I figure you must be right with that cause the blogs are showing and theres no channels for them. I just added the channels. Take it they are their for analytical reasons?
channels are for tracking only. you can measure adsense performance of your site/page by creating channels.
It's best to add channels so you can keep track of which site is earning the most $$ (so you know what you're doing right for that site, or if it's a good niche).
