What are chanels? When i set up adsense it wanted me to set up channels but i skipped it.

it just means you can see which ads work best
for instance you could have all your frontpage ads in one channel or all the text link ads in one channel

I use channels alot to see which ads perform the best
Also useful if you have several sites

i even have a DP channel to see my earnings from the ad sharing

 

you can setup channels for each ad code you generate to keep track of which ad block is generating the income and how its doing. usually people with multiple ad units and multiple sites use channels to track performance

 

Channels means if you had single site means no problem. You can find income from that site. If you had multiple sites and you want to know from which site you are earning then use channels for that. Then you can know from which site you are earning.
