Make the affiliate link simpler

Problem/Motivation

I added the module and sent sample of the affiliate link to the site owner and she immediately said, "Could you make the link a bit simper? I think we would prefer it simpler and shorter."

Steps to reproduce

Can I suggest for the affiliate link to be made simpler like https://www.site.com/affiliate/4 instead of the present
