Here is an example:
https://www.zazzle.com/store/annarosaenergyartist/products?qs=italy%20golf%20balls&dp=252696032451593756
I would like to add my affiliate code as well as tracking.
two(?) keywords are italy and golf balls.
If there is a question mark in the url then I think you add this & between the end of url and your referral code
