I didn’t realize this until a book group I belong to on FB pointed it out; if you have an author page on Amazon, there is a like button. Supposedly, the more likes you garner, the more Amazon is likely to promote your book. I think this is a great idea so I’m throwing my author page link out there. And I highly recommend any books you really enjoy, see if that author has a page and do the same for them. Any and all promotion helps, and indies need and love all support they can get!
