Nothing! Except for your desire to be an affiliate.
You don't even need a website (although having your own website helps). You can promote our product via search engines (Learn how), postings in internet forums, tweeting, posting links on Facebook, LinkedIn, recording videos, or simply email to all your friends and people you know with your affiliate link to our product.
All you need to do is to send a visitor to our site via a special link (called 'affiliate link'), and if he or she buys anything from us, you will get 75$ for each first deposit of each new user.
