Problogger.net has a great article on Chitika channels posted. Has all you need to know on how to implement them into your code. http://www.problogger.net/archives/2005/11/08/chitika-add-channels-to-eminimalls/
huh? didn't you put your onwn channel there? like if you have a pets store you would put ch_sid = pets; unless I didn't understand it
If you show only one product in your ad unit then you can track clicks with channels for this product. If you use more products in your query than your channels work on ad unit not on single product in that ad unit.
Aw... shit... you are right, I used one channel per site, so I will be able to track the site but not the individual ad... Dammit, now I need to go fix like 80 ads and change the channel again
Yesterdays report just appeared, I wish I had done the ch_sid = ch_query yesterday, but still very interresting information - I only had one product on some channels so it was possible to see what a few keywords paid.
