How to market a book
Recognize that the best marketing campaigns began long before the book is published.
The truth is that you will be fighting an uphill battle if you don't start building a following long in advance. Remember that market requires both a strategy, as outlined above, and an actual market of people to implement that strategy on.
Though there is no magic formula, try taking one to two hours of writing time a week and turn them into " book marketing " time. As the book gets closer to publication, you can ramp up the hours spent marketing.
