So I just created a new widget that would show up in a product page in my site. This widget will show several products similar to the product that is displayed in the current page. The purpose is to help users compare similar products.

Let's say in the product page A http://domain/products/A

The Similar Products widget will show

• http://domain/products/B
• http://domain/products/C
• http://domain/products/D
• http://domain/products/E

My question is how to track this "Product B page were visited X times from Product A page via Similar Product widget"? (And there is also chance that Product B will show up in the widget on Product C page)

I have this idea using the Event feature from Google Analytics. But I'm still not sure if it is or what is the common best practice for this.
