235 Places to Promote Your eBook for Free (Or Low Cost)
Here are 235 ebook listing sites, Kindle freebie sites, book review sites, author listing sites, a few ebook retail sites, and Facebook ebook groups (which I will try to keep updated with your help). Note: Many of these sites also feature printed books, so check them out even if you don’t have an ebook yet.
Some of these sites offer free listings. Others charge a minimal fee for listing. Good hunting!
Before starting on the listing, here are six ways to make good use of these 235 ebook websites:
Kindle Giveaways — Use your Kindle Select free days to give away your ebooks at sites designed for free Kindle days. There are many such Kindle freebie sites in the following list.
Short Excerpts — Feature short excerpts from your books and novels on freebie websites. You can also use excerpts as an incentive to sign up for your newsletter or fan club email on your website.
Short Ebooks — You can build an even bigger audience by giving away short ebooks that are more substantial than just an excerpt. Again, you can use these short ebooks as newsletter signup incentives.
Older Books — To promote a second novel, give away your first novel to build interest in your upcoming work. You can also promote your first book at a lower cost (99¢ or thereabouts) rather than as a freebie.
Listings for Links — Add your book listings and author websites at any of the following websites that allow you to include links. These links will increase your search engine visibility, encourage more people to visit your website, and help you sell more books.
Author Pages — List your author (or yourself) on any websites below that allow you to create an author page. Many of these websites encourage such listings.

http://blog.booksontheknob.org/subscribe-about-contact/authors-read-this — This blog grew out of an effort to keep my family and friends up to date when books were on sale or free in the Kindle store or an author website. Since then, it’s grown to encompass many ebook platforms and includes free or extremely good bargains on music downloads, games or any other item or promotion that catches my interest. In addition to book sales in the major bookstores, I alert readers as to special coupons available for free or nearly free books, but generally disregard any “free samples”, “free excerpts”, books with advertising or other gimmicks, including those that seem to be mostly intended to get email info for a mailing list (ie, internet only books created just to give away and drive traffic to a web site). I get more books to review than I can possibly read, but do mention them in conjunction with their release or a special pricing. I don’t read all the books that get mentioned on my blog (I don’t have the time, for one thing) and most I find on my own and purchase with my own money, a task eased by their being free, for the most part. Some books are sent to me by the author for review, either in electronic or physical form and I try to mention that when the book comes up in a post.

Unlike other book promotion sites, we like to focus on new releases. Nothing makes a bigger impact on the lifetime sales of your books than a kickass book promotion right at the start.
But please, don’t expect to get accepted for a book promotion if your book isn’t good, your cover isn’t professional, your book description has typos, it’s 23 pages long, and has no reviews. We want our subscribers to always feel like they are getting A LOT of value for the 99 cents they pay for books as well as the time they spend reading them. So go pro or go somewhere else. We don’t want slop or Kindle scammers trying to “hack” a profit churning out unoriginal bleh. We want high-quality authors doing things the right way. You do that and Buck’ll have your back every time you need to launch a book with a bang.
To apply for a promotion, simply fill out the form below and you’ll be contacted within a matter of days with a “yay” or “nay” by the Buck Books gatekeeper. We charge fees based on a rolling average of books sold, and our fees are always fair because of it. We use these fees to put on huge events to build our subscriber base every month, and we aim to grow this thing into a force to be reckoned with in the book promotion world.
To have a chance to be featured at Buck Books, your book must be priced at 99 cents or less during your promotion, its listing on Kindle must show that it is at least 60 pages in length, you must have at least 10 reviews with an average rating of 3.8 stars or higher, your book description must be well-written and free of any major spelling or grammatical errors, and your book cover must be designed by a non-Fiverr professional designer or book cover design service.
