As an affiliate, all you have to do is sign up for a ClickBank affiliate account and then start browsing their marketplace which lists all the available products from their partner vendors. Once you find a good product (we’ll get into that in a moment), ClickBank will give you a unique “affiliate link” that points to the vendor’s sales page. All you have to do then is make people buy through that link. You earn a commission for any sale made through your affiliate links.
Ideally, you will already have a website that contains articles and other affiliate offers similar to the ClickBank products you want to promote. If you haven't set one up yet though, don't worry. WordPress is a great free content management system that you can use to start a website and begin publishing articles immediately. Use your articles to draw readers in, then present your ClickBank affiliate offer within the article. You may also want to develop a newsletter for your own website and use it to promote your ClickBank offers to your audience as often as possible. (See: How To Monetize Your Website.)
