Book reviews are not only important to book marketing, but they are crucial, especially when it comes to self published book marketing. Most writers should do whatever they can do to get favorable self published book reviews in order to promote their writing.Most book reviewers write for a living. They work freelance at this type of job, read books and write about them professionally. They know how to write about a book without giving away an ending or too much about the plot. Good book reviews should leave the reader wanting to read more, they should give a reader a glimpse into the writing that can help the reader make a decision as to whether or not they want to buy the tome.If a writer has a self published book, it can be difficult to get a writer to write a review. Not so if the writer sends the work to a book review service. A book review company can allow for the writer to be heard in that someone will read the work and write a professional review about it. Some services will allow for more than one review to be written about the work. And these are important as many people base their decision on whether or not to buy the book on the reviews. If a novel comes highly recommended by reviewers, it is much more likely to sell than one that no one has ever heard about.It is in the best interest of any writer to see to it that their book is reviewed by professional book reviewers and is given a proper notice as this can be vital to the success of a book. Using a book review service is a good idea, especially in the case of a self published author as they will not have a good chance of getting a professional writer to look at their work without using this type of service. Book reviews are the way that the public gets to know if the novel or writing is something that will interest them. They should not be a sales pitch for the writing, but should just discuss the plot of the book, the writing style used by the writer and the strengths of the book for the reader. It will then be up to the reader to decide on whether or not to read this novel, based upon what is said in book reviews.
