The Independent Author Network is a new service aimed at self-published authors. It was designed to serve as an unified author page, that tells the public what the author is all about and also links to their books and social media networks.
Amazon and other bookselling companies allow authors to setup their own pages, but tend to only promote books that that are for sale on their particular ecosystem. The IAN is more agnostic, authors can list their eBooks now matter where they are for sale. If an author sells physical books, there is code you can copy and paste for customers to buy it directly from services such as Paypal or Stripe.
IAN promotes books you list with them to over 300,000 followers and over 16,000 people a day visit the website. You can list your author profile for free, but they ding you if you want to sell your books.
If you have 1-6 books to promote, the membership setup fee is $24.95. A Silver membership allows you to include and promote 7-13 books on your page and costs $49.99.
In the end, the Independent Author Network may be a viable way for authors to promote themselves and get their names out there. Sure there are services like GoodReads and Amazon for this sort of thing, but constant promotion is certainly not a bad thing.
