Selling self-published books includes:
Distribution. Make your books available at Amazon Books, or other online distribution networks as well as local bookstores. Additionally, if you initiate your own publishing label and ISBN number Bowker Books, your books will be listed in Books in Print and made available at schools and libraries. Presently, there are only some 1700 brick and mortar bookstores in the USA.
Marketing: Once you have selected a distribution outlet, identify your target market and let interested readers know the books exists. This includes doing podcasts, interviews, YouTubes and whatever you can do to connect with fans. Since over 80% of books are sold online, this using social media is a great approach.
Book Reviews: Work hard to get book reviews by sending out an advance PDF copy to key reviewers. Ask people to review on Amazon Books, if you book is listed with them. Reviews help sell books.
Advertising: Create an ad campaign to reach potential readers in certain niche magazines, TV, radio or online venues.
In Person: Schedule book readings in your local books stores, as well as book speaking engagements to sell your books at various events. Volunteering for speaking events usually will net in quite a few books sales. FURTHER READING: 5 Steps to Market a Self Published Book
