Best Book Promotion Sites for Kindle Authors (2026)
Choosing the right book promotion site can make or break a Kindle launch or free promotion. With dozens of options available, it's hard to know where your money is best spent. We've compared the most popular platforms side by side — covering features, pricing, strengths, and limitations — to help you make an informed decision.
Quick Tips for Authors
- •Stack promotions — booking 2-4 sites within a day or two of each other often outperforms a single expensive promotion.
- •Match the platform to your price — some sites specialise in free books, others in discounted. Check before booking.
- •Genre matters — platforms perform differently by genre. Romance and Mystery tend to have the largest audiences everywhere.
