First, let me say I know next to nothing about CJ's systems. However for the purposes you are envisioning, there are a number of commercial products that will give you ROI on a per keyword / per referrer basis.
If you try searching for things like PPC management, or roi tracking software, etc in your favorite engine, I'm sure you can find a few commercial products that will fit your needs.
The basics of ROI tracking aren't that difficult, at the 'root level' all you need to do is set a unique cookie based on referrer & keyword, and then start logging the user behavior on your site after that.
However, they won't be syndicated to their partners (AOL etc) until after they have been reviewed by the Google Editorial team.
If you are doing affiliate stuff, there are a few options -> use your own redirect *before* the user gets to the merchant redirect, so you know what keyword(s) motivated the click through to the merchant (yes, incomplete cause you don't have a sale, but "closer" to getting what you want). Between the keyword data that can be gained this way & a time stamp, you can correlate some of the sales to keywords, but not all, certainly.
Then, some affiliate programs offer their members the ability to insert a tracking gif on the 'thanks' page, which when used with a product (like those you mentioned) can give you the 'ROI' part of the equation you are looking for.
>I had the "see your ad in 15 minutes" hype in my head and wasn't expecting to have to wait 2 or 3 days just to get started...
I don't remember waiting at all after signing up.
I thought it was live right away.
Uhm... Did you fill out all the forms on [adwords.google.com...] already? The term 'autoresponder' in your post puzzles me and you have to enter your creditcard-details during signup. Did you sent any email to google and expected to see your login-details being sent back to you?
Just go to their website and signup. You will really see your ads going live a few minutes later.
i did read that G editors don't work weekends and that if you make a change to your ad copy on a friday night, it won't appear on the partner network 'til monday. can anyone confirm this? thanks.
