Become an Author of the Week (100% free author promo!)
Author of the Week is a page and a post about the author, a list of his/her book(s), a picture of the author and a short bio. There is an interview segment, usually between 5 to 10 questions depends on the author and a list of the authors awards and/or recognitions.
Also anything else the author provides or wants to do for the page, most authors do a giveaway.
