How do people track conversions? Meaning I need to know which keyword the customer searched (mostly PPC) and whether or not they bought and the percentage of people that buy vs the ones that leave. Where do I get such software?
You should be able to do this if you have a Google Analytics Account. You can set your goals, track conversion and get more useful stats about your campaign. plus its free.
just take that tracking code thriugh google analytics and put it there on you conversion page(the page thats comes when the transaction is completed)
