A brief overview of you and your affiliate experience (are you new to affiliate marketing? Do you run a blog? What kind of industry do you promote?)
The amount of traffic (annual unique hits for the last year or two) you receive to website(s) on which you want to promote affiliate links.
The tracks you would like to promote – currently, Gumroad only allows for affiliate links to be generated for specific products, although we can add a bunch of tracks to your account when setting things up like a collection that is relevant to your audience.
