Tracking affiliate click for payment

Hey friends!

I have a niche blog that monetises through affiliate sales. I want to start having guest bloggers write for me and I’d like to offer them a % of the affiliate sales they generate from their content directly, typically with Amazon Affiliate Program.

I’m really struggling to figure out how to do this (or if it’s even possible?)! Has anyone managed to do this and/or can offer some advice?

Thanks team!! Adam
