Has anyone done any development on trying to track the performance of Upsell or Related items? It would great to know if any of the items that are rendered in this area of the product detail page ever make it to the cart. We're trying to find a system that would allow us to look at an orders cart items and determine if this item or that item was selected by the visitor while on another products page.
The next peice of this would be to track link activity from pages like; best sellers, featured items, category or departments pages. We use affiliateid's alot but the problem we see with that is the affiliateid changes.
thanks, troy
