Digital book sales are growing in the self-publishing market, in most book genres.

We’ve been paying close attention to the book market and sharing the trends on our blog since March 2020. From then, we recorded how indies selling digital books via PublishDrive saw growth by at least 20%. In April 2020, it was another 23% growth. In August 2020, we reported a 69% increase in a one-year time period -- 70% of those sales from global markets. In September 2020, we’re still seeing positive growth rates.

In September 2020, compared to last year in September 2019, there was a 59% increase in sales via PublishDrive. Compared to the previous month in August 2020, there was a 4.5% increase.

In September 2020’s report below, we give an overview of international digital book sales plus bestselling book genres, book categories, markets, and more. We’ll continue to update this study every 20th of the month, so make sure to tune in. Our aim is to help you make the best-informed decisions wherever you are in the publishing process.

By the way! We recently held an open webinar about how to increase book sales with PublishDrive. Here’s the recap.

Price promotions delivered strong results

We analyzed 800 book promotions for online retail stores in September. We discovered that the most successful results came from discounted books originally priced at around $9.99. These price promotion strategies ran for an average of 1.5 weeks before generating an increase in sales. Some of them are still running in October. On average, we’ve seen 10x more growth with effective price promotion strategies. They also achieved an extra 2% growth to overall sales for non-promoted books.

Running a price promotion campaign is a strong sales tactic. With PublishDrive’s price promo tool, publishing authors can set them up wherever their titles are being sold. We also got exclusive partnerships like with Written Word Media. They let indies run various price promos to outside networks with hundred-thousands of readers (see more).


Digital book sales continued to grow

In 2020, people are seeking more at-home entertainment, prioritizing digital means to get them. Movie-streaming services, video games, and of course, books are seeing significant booms.

Since COVID-19, PublishDrive’s digital book sales grew by 20% in March and 23% in April. With the world opening back up, the rates flattened slightly in May and June. In July, there was a monthly bump of 20%. In August, we reported our highest 69% increase in sales in one year’s time.

PublishDrive Digital Book Sales Growth in September 2020

In September 2020 compared to September 2019, there was a 59% increase in sales via PublishDrive. Compared to August 2020, a 4.5% increase. After the Christmas holiday season, summer during July and August is the strongest for book sales. Then we usually see a stagnation during the autumn season. Our current data shows that instead of stagnation, digital book sales continue to grow.

The growing book sales we’re seeing are beneficial for PublishDrive users who keep 100% royalties. Since we don’t take any commission, indies get the same royalties as selling directly to stores. All this growth is 100% theirs.


Nonfiction & fiction like fantasy, science-fiction, & thriller genres did great

In September, both fiction and nonfiction books performed well. Bestselling fiction genres included Action & Adventure, Crime, Fantasy, Historical, Literary, Mystery & Detective, Romance, Science Fiction, and Thriller.

Digital stores funneled the most sales

Book royalties come from different sources. For authors enrolled in KDP Select having to sell only to Amazon, they might miss out on 60% of the market. In PublishDrive, we’re generating sales from more store types:

  • Retail: Major outlets reaching global readers. E.g. Amazon, Apple Books, Barnes & Noble, Google Play Books, and Kobo.
  • Subscription services: Applications or stores that provide unlimited access to books for a monthly subscription fee. E.g. Scribd, Bookmate, and Dreame.
  • Digital library providers: Book borrowing for not just individuals, but institutions like public libraries, schools, universities, or corporate libraries. E.g. OverDrive, Bibliotheca, Mackin, and Odilo.
  • Regional stores: Outlets that cover specific regions serving local communities. E.g. Tolino and Chinese stores.

As reader experience shifts especially In 2020, more people are using online modes like subscription services and digital libraries:
