I was wondering what would be the best method to earn income of a free ebook download? I have few ebooks that I would like people to be able to download for free, but I would still like to make a profit from. I was thinking an effective more would be to have them sign up for a newsletter/mailing list for them to get the free download, and then email them with promotions and affiliate links. Also, that I would send them a newsletter with content they would find of value, there for inceasing the likelyhood for them actually clicking the promotion/affiliate link. Would this be a good method to make money from a free ebook download, or would there be a more effective way to profit from them?
