Conversion codes...
 

Do any of you know any roi management script that allows me to track
findwhat and other smaller ppc engines traffic? Something similiar to google adwords tracking?

phpadsnew will let you do ROI tracking of text ads, banner ads, etc. etc. blah blah.

Just make your ppc link a "text ad" in the system, and you're set.

it's free as well, which is always a plus:

thats for banner tracking though, I am talking about tracking for search engine click throughs
