I've sold a few ebooks on digitalpoint in the past and must say it's a great money maker, 4 hours writing an ebook and selling it can easily yield $100 or more. My problem is I only sell at most 8 or 9 ebooks at around $10-$20 a pop. I aim to sell at least $500 worth of each ebook i sell. How can i achieve this more easily? What methods tend to have better results selling ebooks at dp?
