I have built a small wordpress widget that floats in the bottom right hand corner of my client's website(s), so that their users can click it to make a payment to them... which simply redirects the user to my payment platform / website where my customer has an account.
FLOW - widget sits on clientwebsite.com and when they click it, the customer is brought to mysplink.com/abc (their payment profile on splink)
I need to be able to track how many users land on mysplink.com from a widget that sits on another site.
I was thinking of using something like mysplink.com/abc/ref=widget-abc and then i can view that in Google Analytics?
01 - would this approach be the best way to do this?
02 - any other advice on approaches would be greatly appreciated
Thank you in advance for your help.
