I'd really like som advice on how I can get people that reads my free eBook to spread the message and help promote the free ebook. I wanted to do it like affiliate marketing, but when something is free, it's not as easy to get people to promote it for you (because they won't be earning money by doing it). I have thought about creating banners, pre-written tweets, emails, articles and so on. But I don't think that this would be of much help, because people would need an incentive in order to actually promote it. - Jens
You can offer an rebrandable ebook which they can include their affiliate link in it, the affiliate program may be one that is set up by you.
