At the end of the day, the return on investment you get on your advertising is what tells you if a site is worth advertising on or not. Google Analytics is a great tool as some have pointed out. If you setup campaign tracking URLs using the Google URL Builder
, and setup Ecommerce tracking on your Google Analytics account, you'll be able to determine the following (and more):
1. How many clicks XYZ advertisement sent you
2. How many sales XYZ advertisement generated
Compare that with your other campaigns, and your finances to know if you should continue advertising there. I'd definitely suggest knowing how much you want to spend per sale to get new clients. Expect to pay at least 2 months revenue per sale.
