How do affiliate links to demo pages work?

When a customer buys an item from its demo page many times is redirected to a page where he/her has to create an account (sign up, meaning no earnings) or sign in (example link), in other items they are redirected to the main item page. So my question is, in the first example, I won’t get any gains because it would count as a sign in, am I right?

I had created over 2000 affiliate links and buttons on my site for the demos :frowning:

Thanks in advance :slight_smile:
