how to track sales from different sources?

[aromacloud]

I worked with a DVD company on its marketing. I created a landing page for Adwords, overture , e-mail marketing and two affilicates.
Then the DVD company's web site is going to handle all check out requests.

Is there any tracking software or online service that I can use to catagorize every sale I make?

From tracking , I want to know which sale is generaged by adwords , which is by overture and which is by e-mail marketing.

thank you so much!

There are services out there that do that for you. You can also do it yourself with some cookies and put some codes in the URL's that you use in your PPC account.

Because the check out requests are not on your site, you would need to either get the data from them or you could "page tag" your "check out" on their site so that it writes information back to your site. There are a number of tools out there that use Page Tagging. We use a product called NetTracker, which allows the use of Log Files and/or Page Tagging together. This allows us the ability to see information that log files can not capture and information that page tagging can not capture, together in the same reports.
