Sorry it came across like you thought it wasn’t possible when saying source website can’t see the data. With some pretty basic js it is trivial, but yea web server access logs won’t give you that detail… but hardly anyone runs a serious site with only serverside detail now, especially in a world with so much cdn and 3rd party integrations direct from the browser.
Your splitting hairs at this point.
My point was without SOMETHING to track clicks, you… Don’t.
