Hi Mike,
Right now I use google conversion tracking, but I just added MSN and Yahoo PPC, so I wanna track it all...
Yeah, you do, I already mentioned AdTrackz, and DW mentioned AdWatcher, these are probably the top two in tracking, along with something like DynaTracker and a few others...
As you see, the best you're probably going to do 'non-hosted' is AdTrackz that I know of... or one of the others, but I like AdTrackz...
Unfortunately - you don't HAVE IT ALL to choose from, AdTrackz will do Google automatically, just set it up and it tracks clickable keywords, google analytics will do it too, if I were you, I would consider contacting Jonah over at AdTrackz about adding Yahoo, MSN support, his product is stable and been around for years... see other posts about this...
I was wondering how you liked it and one big thing I was wondering is if it had a PPC Fraud Click check built in?
I really like AdTrackz it does exactly what I need, but I haven't used it yet for PPC, I'm not up to that point yet, but will be soon, I'm sure as long as it's been around it works, I've been running it for years! Consider contacting Jonah over at AdTrackz, he's helpful but can take a while to reply...
Let us know what you find out...
