Have you put your book out there and been disappointed in your sales? Perhaps you’ve tried a variety of marketing tactics to boost discoverability: blog posts, social media, book tours, paid ads in a variety of venues. But nothing is working. The publishing landscape changes every year. The number of books published has increased and the competition for readers is more than it has been before. The key is to?define your audience and then convince those potential readers of the?value?of your book. Your marketing time and money should primarily be spent on a message of value–not price, not story, and not genre. This book provides specific techniques to exploit that value without resorting to the typical overexposure in social media and newsletters with “Buy My Book” sales messaging. Instead, focus on the top three proven techniques that actually sell books. Follow step-by-step instructions and timelines to learn how to: 1) Create an Effective Plan for Communicating to Readers; 2) Use Social Media and Email lists to Engage with Your Readers; and 3) Plan for Effective Campaigns for both Book Launches and Backlist Rejuvenation throughout the year. In addition this book provides techniques to: Distinguish specific groups of readers most likely to buy your novel or nonfiction book. Understand your competition and the advantages that your book offers. Clarify hooks that capture attention of the media, reviewers, and readers. Identify where and how to reach readers, reviewers, and media. Create and implement a consistent brand throughout all marketing efforts. Effectively select, from 100+ options, the appropriate marketing tactics and timing that matches your book intentions and values. Maximize organic reach and stay to a budget of less than $100 per book campaign. Develop a long-term online marketing plan.

Once you have a finished book, you need to get it into readers’ hands. Loading your book to a vendor looks deceivingly easy. However, the career author knows that each vendor has its own methods for promoting books, performing searches, and identifying ready buyers. You need to take advantage of these differences in order to maximize your profits and discoverability. Capitalize on competitive retail pricing in different markets, and use effective metadata to draw more readers to your books. Learn to: Write compelling book blurbs for each title that focus on “reader cookies” and marketing. Unlock keywords and get access to hidden category options. Take advantage of search algorithm nuances at Amazon, Barnes and Noble, Kobo, and Apple. Use aggregators to increase distribution opportunities around the world. Evaluate opportunities for direct sales to bookstores and individual consumers.
