on Just Publishing Advice:
It’s easy to overlook all the Amazon book promotion tools when you are busy self-publishing your new book.
Even if you have already published your book, there are sometimes changes and new book promotion tools added by Amazon.
Any book promotion is worthwhile, so you should always look at every means available to you. Social media, your author’s website, and perhaps paid book promotions will all help.
But never forget that Amazon wants you to succeed in selling books so it can make money. That’s why it’s always worth checking what book promotion services Amazon is offering.
