You create a digital information product, and work hard towards your product launch. You announce it to your list. You’ve even done quite a bit of legwork in advance and promoted it via email, Twitter, Facebook, article marketing and guest blogging… and maybe even a guest interview on a web radio show. The big day comes. You’re quite pleased with the sales. But they trickle off within the first month - perhaps even the first week or two – and after that, you’re lucky if you make $100 a month on your product.
