There are a number of self-published book tricks you can learn that can have a huge impact on the success you will eventually achieve. Many of the most effective tricks and tips require a very deep understanding of people and a lot of creativity.
One of the benefits of self-publishing is that your book gets to market faster than it would via traditional methods. The internet means you could (theoretically) complete a book today and publish it online tomorrow. You can consider self publishing books services if you want to self-publish your books.
Another very effective technique from the pile of publishing tricks is to create a promotional or media event around a book that you self-publish long before it is published. The idea is to create news stories in the media that will have people sitting around waiting for your book to be released.
This is one of Hollywood's most popular tricks for marketing movies, and that shouldn't be the reason why it doesn't work well for your self-published book.
Another craft trick is to come up with a self-publishing book title that can't be ignored. If your title doesn't work, don't worry, change it. One of the most common tricks publishers use on non-sellable books is to repackage them and give them a fundamentally new title.
This trick has worked well in most cases and is worth considering if your self-published book doesn't sell well at first.
