i have few sites which is enabled with adsence. but i cant onitor their trafic and clicks separatly to which one needs to improve and which sites gives the best profit etc. how can i monitor them separatly through adsence. i dont want anythink like traffic counters

 

Create a channel. As your creating an ad, there'll be a screen if you want to use a channel. Create a few, and use them with the code.

 

By creating a channel you can monitor your earnings

 

i normally do like so:

sitename-position-adsize
sitename2-position-adsize
sitename3-position-adsize

etc
