If you look at the Amazon home page you will find that all their links are using a pattern like this one from their navigation menu.
I would like to track my website like this. How do I do so?
Are there advantages to parameter tracking compared to using the referrer header? (I know some clients might have referrer disabled but I suppose most clients still have referrer enabled? And they are doing internal links so referrer header should always exists, i.e. unlike from Google search results)
