Question re Affiliate tracking code URLs

Quick question re affiliate links

Assume you have a url for a content page: site12345555.com/tubepage.php

Questions

Can you put an AFFILIATE ID on that content page so affiliates who refer that page will get paid if a visitor buys ANYTHING from the page (the page has ads)

site12345555.com/tubepage.php becomes site12345555.com/tubepage.php?aff=1234

Can wordpress autorender the ads' urls if the visitor comes through an affiliate link?

Would this still be TRACKED ACCURATELY by the affiliate program?

Thank you in advance

blackbeans, look into affiliate link cloaking plugins, or affiliate link managers, among others. These allow you to track affid's. I don't believe it's possible natively.
