Barnes & Noble publicly credited BookTok with driving a surge in fiction sales — particularly romantasy and dark romance — and the association between BookTok and fiction is strong. If you are building a Shopify bookstore around non-fiction categories, it is reasonable to ask whether BookTok is even a relevant channel for your audience.
The answer is more nuanced than "BookTok is only for fiction." Non-fiction is present on the platform, but it operates differently — different creators, different hashtags, different emotional hooks.
The Fiction Dominance Is Real
The #BookTok hashtag ecosystem with 200 billion+ views is overwhelmingly fiction-driven. Romantasy series like A Court of Thorns and Roses by Sarah J. Maas and dark romance titles dominate the most viral content. Emotional reactions, shipping characters, and aesthetically pleasing cover shots drive engagement in ways that work naturally for fiction narratives and far less naturally for a business book or a history text.
If your store specializes in literary fiction, fantasy, romance, or thriller, BookTok is one of your most powerful channels. If your store is primarily non-fiction, the picture is more complicated.
Non-Fiction Categories That Do Perform on BookTok
True crime: True crime content on TikTok has its own thriving community entirely distinct from #BookTok. Creators who summarize cases, review true crime books, and discuss forensic details reach audiences of highly engaged readers. Titles from this genre regularly see BookTok-driven spikes.
Self-help and personal development: The self-help market is approximately $11 billion globally, and TikTok has a robust "self-improvement" creator community. Videos structured around takeaways from productivity or mindset books ("three things I learned from [book]") perform well. Hashtags like #SelfHelpBooks, #PersonalDevelopment, and #BookRecommendations (broader than #BookTok) are the relevant discovery surfaces.
Memoir and narrative non-fiction: Books that read like stories — memoirs, narrative non-fiction, immersive journalism — cross over into the fiction-reading audience well. These titles get reviewed on #BookTok almost as frequently as novels when the storytelling is compelling.
Categories that largely miss: Dense academic non-fiction, textbooks, technical reference works, and business strategy books have minimal organic BookTok presence. Those audiences are on LinkedIn, in professional newsletters, and on Reddit — not scrolling TikTok for book recommendations.
The Practical Takeaway
If your Shopify bookstore carries self-help, true crime, memoir, or narrative non-fiction, BookTok is worth pursuing — but with different hashtags and creator partnerships than a fiction store would use. Focus on creators in those specific communities rather than generic #BookTok accounts, which skew their content toward fiction regardless of what you pitch them.
