Find an affiliate program. Affiliate programs provide you with a unique ID and marketing materials, and then pay you a commission based on how much business you generate.
- Most websites you've heard of offer such a program. Since there's no cost to the site for letting you do this, practically anybody can become an affiliate for as many sites as they want.
- Start with well-known brands. Amazon offers a competitive affiliate program that pays a percentage of any purchase a person makes after clicking through from your post, even if it's not anything you advertised. Apple's iTunes program has an affiliate program as well.
- Add in smaller programs. Though less likely to generate money on a given day, you can diversify and gradually increase your affiliate revenue by offering a wide range of advertising services to many different businesses.
Sign up. Once you've decided to market a company as an affiliate, search the company's site and fill out the required forms. This should always be free, and usually only takes a few minutes.
- Don't ever pay to become an affiliate.
