As an author, I am always looking for new places to promote my books. I have asked other authors on various social media platforms and created a list that I regularly use. I would like to share this list with you. Most of these are free for a limited time, unless otherwise stated.
Awesome Gang
They offer a free promotion, as well as a paid one. The paid option offers a guaranteed spot on the homepage and various social media promotional boosts as well.
Pretty Hot Books
They offer a free promotion as well as a paid one. The paid option guarantees a featured spot on their homepage for 7 days, and your book is sent out to their social media platforms as well.
Free & Discounted Books
They offer options to list your books that are discounted for a limited time, available on Kindle Unlimited, and permanently free. Both free and paid promotion options are available.
Discount Book Man
This site offers both a free and paid promotion option. The paid option offers a front page listing for 5 days.
Content Mo
They offer two free listings per month. Paid options are also available.
eBookasaurus
This site offers both a free and premium promotional listing. For $10, premium book listings include author bios, social links, additional store links and are featured on the sidebars through out the site.
Snick's List
This site allows you to run ads for all of your books free for three months, six months for $2 per book, and a year for $4 per book. They promote your books across multiple social media platforms and by email. Your book does not have to be free or discounted to be listed here.
I hope that at least one of these helps you in your book promotion endeavors. If you have any others that you use and have had success with, please leave a link in the comments.
