Post how many channels (url and custom) do you have/use in your adsense account mine's: Url channels: 8 Custom: 3 (to be deleted ...)
For each site i have i make 1 url channel for the root and custom channels for the subpages (one for each cathegory). Advantages: easy to spot goods or bads inside of your site + the numbers of clicks from the url channel equals the sum of the custom channels, if not then someone copied your adsense code and uses it on his site (mabe to hurt you) -> it's time to mail G. Disadvantages: the stats page looks like a mess and takes some time to figure things out.
about 5 custome channels... want to make more.. but no time to add channels and then change the ads on the site
Way too many... I channel every domain when I buy it (up to almost 100 now) but I cant keep developing sites at the same rate.
I don't know how many here visit webmasterworld, but there is a long thread there speculating that google use our custom channel information for smartpricing, and that some people have improved results by removing custom channels. Sounds pretty unlikely? Yep. Statistical anomaly? Could well be. Possible? Who knows how google work. Just something else to bear in mind.
Same here and yes, it is a mess at times to see the day by day stats and see that mess. But worth it as it shows me which domains and pages are not doing a thing so I can find out why. Doing this does help in increasing the ctr and pay, but it does take time as first you have to see the entire month to get a valid picture. Then make the changes and see what happens over a 2 week period.
