📌 Build an audience using Facebook and Instagram (and optimize your profile with an image and link to your book)
📌 Build an email list and send them weekly emails they find interesting/useful. At the bottom of each email place a link to your book.
📌 Participate in Facebook groups that are relevant to your book (e.g. if your book is science fiction, join a science fiction group). Share your book whenever the time is right.
📌 List your book in low competition categories and sub-categories relevant to your book genre.
Amazon allows up to 10 different categories per book. With initial publishing you will only be allowed to select two main categories but you can contact Amazon’s Help after releasing your book to add additional categories.
📌 Optimize your search keywords.
Choose keywords which have acceptable search volume but low competition (and are of course relevant to your book). You can have seven keywords for your book.
Don’t overcomplicate marketing! It’s all about testing and figuring out what works best for you and your audience.
