I have recently published two books (paperback via createspace).
Could you advise what are the best methods to advertise these books?
i.e. Amazon PPC - how does one do that? And must the book be in Kindle format for this option? I am in process of making my novel into a Kindle edition.
Facebook adwords, Google etc
Any other methods?
What is the best way to get more genuine reviews?
and finally, DRM or not?
I don't recommend using DRM. The articles I've read on it say people get annoyed because they can't view the book on their multiple devices and the hackers find it easy enough to remove the DRM which is why you'd have it in the first place. So it's a lose-lose proposition.
