It's free to become a Hostgator affiliate, and their tiered payouts are substantial — you can make $65 per signup if you provide Hostgator with 1-5 signups per month, and up to $125 per signup if you provide Hostgator with over 21 signups. You can either embed tracking links on your site or create a custom coupon code. Since Hostgator provides a 45 day money-back gurantee, it's low-risk for your website visitors to try it out.
A more complex system, pay per lead affiliate programs compensates the affiliate based on the conversion of leads. The affiliate must persuade the consumer to visit the merchant’s website and complete the desired action — whether it’s filling out a contact form, signing up for a trial of a product, subscribing to a newsletter, or downloading software or files.
