I think anyone that is self-publishing their books on Kindle, Nook, and Smashwords is 1)Very wise considering the atmosphere in publishing today, and 2)Looking for the success denied us by traditional publishers. So we, in our optimistic states, upload our books and wait for success. Then it happens....Nothing.
Our first thought is that there must be something wrong and start the crazy process of checking our sales every hour. Then we go into the crazy state of telling ourselves what bad writers we are. Then we go even more crazy by coming up with crazy promotional ideas that rarely sustain long tern results (i.e. Amazon Bestseller Campaigns).
So what is the problem? Who knows! Some can break in and find their audience with one novel while others are not so lucky. One thing to consider is virtual shelf space and how to make your backlist work for you.
Now, you may be thinking, if my first novel isn't selling, why would I add more? Well, because you can use your unpublished back list to promote other books. How hard is it to add an excert of another of your books at the end? Then you are not only taking up more virtual shelf space, but also using your books to advertise your other books.
So what are the keys to success on Kindle?
1. Write a great book
2. Have a great cover
3. Write a great description
4. Price it right
5. Promote it on your blog or website
6. Promote it using social media
7. Promote it using excerpts in your other books
Just remember that by taking advantage of your backlist, not only are your spreading your work out across Amazon and other outlets, but you can use your work to introduce people to your work. So not only should you get to writing, but also get to uploading!
