How to track conversions from content sites?

Anyone have a good solution?

I disabled content ads awhile back, but with the ability to block sites I'm going to give it another whirl. I just wish they would let us block 2500 sites instead of only 25 LOL. Anyway, has anyone figured out a relatively easy way to track conversions from individual content sites?

I could build a custom system to do it, just wondering if it's already been done or there is an easier way than the way I'm thinking of ...

You can use the G AW conversion tracking tool. Just keep in mind this doesn't ALWAYS track conversions from the partner sites, as some do not allow for user tracking... Maybe thats why your suggesting to build your own? If thats an option for you, I would do that while simultaneously running the G AW conv tracking tool. -That way you can compare the results...

Sorry, what I meant was to track conversions separately for each content site that is sending me clicks. I have an Adwords campaign set-up only for content ads and there is no conversion reporting on the campaign whatsoever. Even if there was it would just give me an overall number. I'm sure some sites send decent traffic and some send total junk, so I'd like to figure out which sites are sending non-converting traffic so I can get rid of them.
