3.) Viability. What's the purpose of your book? What problem or challenge does it solve? Have you determined that there is a need? In other words, your book should solve an existing need, not create a need. What are its benefits? What are its features?
4.) Marketing Plan. What activities will you engage in to sell your book? Book tours? Blog book tours? Book signings? Amazon book selling programs? How does your website fit into your marketing plan? How do you build your customer list? Do you give away any products or services for free? How does media (social and traditional) fit into your marketing? Do you have a plan, or do you just engage in activities haphazardly?
5.) Sales Funnel. Your book is a business, and it's only one part of your business. How does it fit in with other products and services you offer? If you do speaking events, are you set up for back-of-the-room sales? Your sales funnel should include low-price services/products, medium-price, and high-end. What does your sales funnel look like? Is there a natural flow from one product/service in the sales funnel to the others? How do the other pieces of your business (website, blog, social media) support this?
6.) More Than a Book. Many authors find that the biggest benefit of writing their book is that it lends them credibility and opens doors for other opportunities. If you're now a credible expert (because you've written a book) on frogs, women entrepreneurs, or financial stability, what can you do with that? What organizations and associations do you need to be pinging about using you, the expert? Are there workshops, workbooks, events that are natural follow-ups to the message in your book? Can you collaborate with other experts and "celebrities" in your field?
You might be a little overwhelmed by all the questions I've posed. It's not something you'll build in a day. Just like you didn't write your book in one sitting, you won't create the business of your book in one day either. If you're just starting out writing your book, then you can be looking at these areas and working on them at the same time. If you already have a book, then start building the business part of it.
Frog lovers, women business owners, and the financial world will thank you.
