Affiliate System for my Website

[leadsprofi]

So,

I like to implement one affiliate system on my website and to generate URL for every online marketing campaign. because i like to know when someone has ordered it from Organic, and when from any Google Adwords Campaigns etc..

What do you suggest me to implement?

If all you want to do is track your Adwords campaigns then link your Google Analytics to your Adwords account and you should be able to track them easily.
