How to make a good book sale?

Use social media sites:

I know for the traditional book publisher, social media marketing can be a scary thing but think of the untapped market out there. There are over 80 million blogs, micro blogs and forums. 30,000 online news sources, 100 million + web properties, 300 + search engines. These are sites a publisher can go to and engage in conversations and build valuable relationships to build brand, which will increase book sales. Social media marketing operates on a one-to-one times many relationship basis. In other Words, we are creating one-to-one relationships with thousands of people who could become customers and tell all of their friends about a given book. Newspaper, TV and other mass media are a one-to-many relationship, with no relationship to those who see your ads and everyone receives the same message

For the past few days I've been watching a particular well-known author use social media marketing to increase the pre-release of their book. This author will send out tweets like "Pre-order my book and not only get 34% off, but instantly become more awesome." Not only did this tweet promote their book but also by adding some humor to it, gave the follower a sense of connection. After seeing this Tweet I immediately did a Twitter search to see who was re-Tweeting their original Tweet. I was amazed to see 28 followers re-Tweet to their followers about this book. The impact of this one tweet created a one-to-one times-many relationship marketing tool. One Tweet reached out to thousands and thousands of Twitter followers, and this is just one small example of how social media marketing can change book publishing. If this author is also engaging in conversation on blogs, chat room, forum and news sites they'll see a greater increase in their book sales and possibly a #1 best seller.

Publicize the book. Post on bookstore websites like Amazon.com as the author and tell people what it is about, or a little about yourself in an author blog. Make sure people who are browsing by have a chance to understand what the book is about. You could also get your publisher to increase the marketing push for your book... lesser known authors sometimes have very short-lived publication runs... not because the book is bad, but just because people gloss over it in the bookstore looking for the authors they are familiar with. ... Talk it up, post the opening chapter for free online... do anything to get people hooked.

Of course, to be fair, part of it also depends on the quality of the writing and the story. Even with the best marketing in the world, some books are going to fall flat because they aren't a good read. ... But that effort is in the past. If you already have a published work, then get out there and market it. Get people to read it. If they like it, they will tell others. Adding it to top 10 lists on Amazon.com could help... posting author information there would help. Lots of people read those pages to decide whether to invest the money into a new author's stuff.
