In the last several years we have witnessed one of the most significant trends in book publishing: #BookTok. What began with a small group of book enthusiasts exchanging tips and recommendations grew into a marketing behemoth with the potential to make overnight bestsellers out of books nobody ever heard of. As 2025 begins, the influence of #BookTok continues to shape, altering the way books become discovered, marketed, and sold.
Before #BookTok, word of mouth played a significant role, but at a slow pace. Conventional book marketing relied predominantly on book reviews, careful store placement, and feature articles in big-media sources. With the launch of TikTok’s algorithm-powered content discovery, all of that changed, however. Today, a single trending video featuring an emotional reaction to a book can make it a bestseller in a matter of hours.
The change democratized book publishing, providing an even platform for indies to promote books in competition with traditionally published books. With ongoing expansion for TikTok and AI-powered book recommendations added in 2025, the platform is becoming ever more skilled at connecting books with their ideal readers.

With each passing year, #BookTok evolves, bringing new trends to the forefront. Here are some of the key trends dominating in 2025:
TikTok thrives on emotional connection, and no less is #BookTok an exception. Readers become obsessed with books that evoke powerful feelings—be it heartbreak, happiness, or a jaw-dropping plot reveal. Instead of using traditional plot summaries, the most effective book recommendations in TikTok rely on the powerful emotional impact a book can have on its readers. Writers who effectively use this trend, positioning books as “must-experience” reads, are seeing sales go through unprecedented volumes.
As TikTok continues to drive its immersive content, book authors and book publishers have been finding new and innovative ways to hook readers. Some of the newest and most trending approaches include augmented reality (AR) lenses that enable one to “step into” one’s favorite book worlds, Q&A sessions with characters, and AI-created book trailer videos.
While fantasy and romance have long dominated #BookTok, 2025 saw a growing rise in new, niche sub-genres that have developed passionate followings. Dark academia, ecotopian fiction, and cozy fantasy have all seen tremendous spikes in popularity, fueled by concentrated book discussion on #BookTok.
One of the latest trends is the #ReadWithMe challenge, where TikTok users read books together in real-time, sharing live reactions and discussions. This movement has turned reading into a social experience, making books go viral even faster. If you’re not part of it, I highly recommend it.
As #BookTok keeps growing, both traditional book publishers and self-published authors must adapt their approaches. Publishers increasingly prefer to seek out authors with a strong presence on TikTok, and many marketing budgets have begun to move towards partnering with influencers.
But independent authors have one big edge: they can respond in a timely manner to new trends and speak directly with readers, unencumbered by gatekeepers. Many of them are intentionally creating books with #BookTok in mind, expertly weaving in trending buzz and current trends into their work.
As we move into the future, TikTok’s influence over book sales continues to have no sign of waning. Instead, we can expect to see:
In the era of 2025, BookTok is a powerful presence in book society. Its unparalleled ability to bridge books with passionate readers at a real and emotional level changed book sales and book marketing forever. TikTok influencers continue to play a key role in driving trends in book society, and TikTok Shop continues to change the manner in which book writers can monetize their work. For book writers, connecting with TikTok is no longer an option but a necessity for success in the competitive book economy of today.
