An ebook about what you do in your business will boost your credibility and increase your revenue. Whether your business is online, brick and mortar, or a combination of both, writing an ebook will solidify your position as the expert in your field. How many businesses that are similar to yours already have an ebook? Probably none have taken the extra time and effort to put what they know down on paper.
As you write your ebook, let others in your industry know that you are working on your book; this will stimulate the conversation and make for some healthy competition. You may want to post one chapter of your ebook on a website or blog for people to download. This generally makes them hungry for more. It is also good publicity for you and your business and further positions you as an expert.
