Whether it is your shopping cart and data management system, yout teleseminar recording service, your ebook cover designer, or your ebook writing mentor. Be sure to sign up for the affiliate program for each one and then put that link in your ebook. Use the actual URL as well as an anchored text link. This way your ebook will bring you money over time from anyone who reads it and clicks on one of your affiliate links. When you do this throughout your ebook it will become a full time salesperson for you forever. This is called ‘viral marketing’ and will be a huge source of additional income for you, over and above what you make by selling your ebook. You will then encourage people to share your ebook with others, or at least not worry as much when they do, because you will see the revenue that is possible over time.
