In today’s fast-paced and saturated digital landscape, a book’s success increasingly relies on the support of online communities. While traditional marketing still holds value, the viral momentum generated by content creators and their followers has the ability to propel a book to stardom. Though it’s reminiscent of early digital spaces such as Bookgram and BookTube, the impact of #BookTok is unprecedented and transformative. Since its emergence in early 2020, BookTok has amassed over 370 billion views across approximately 52 million videos. This huge reach has sparked a global surge in sales, and has altered the publishing ecosystem, changing the way readers consume and engage with literature. So, what is its socio-cultural impact, what makes a book resonate with its audience – and what are the downsides to this phenomenon? 

BookTok helped to sell over 20 million books in 2021 alone, accounting for 2.4% of annual sales. BookTok’s influence is far-reaching, with bookshops dedicating shopfront displays to the books currently trending on the app, often adding ‘TikTok Viral Sensation’ stickers. Major booksellers such as Amazon have even formed a category called #TikTokMadeMeBuyIt. BookTok fever is fervent, and has proved extremely profitable. For publishers, there is enormous appeal. Authors with a BookTok following come with a built-in readership, meaning the risk of investment is much lower. There are thousands of sub-communities within BookTok, speaking to the fact that it operates as a market rife with competition for visibility, followers and potential brand deals. As a result, publishers are increasingly factoring in BookTok visibility in their marketing strategies. So how does an author go about reaching viral status? 

BookTok content is vast, ranging from reviews to skits, POV videos and Q&As. As with multi-modal platforms, the possibilities are endless and enable creativity. Short-form content often mirrors the books’ tone with TikTok aesthetics. Authors looking to build a following can employ a number of effective techniques to gain traction. TikTok works through algorithmic trend systems and recognises frequent posting, high engagement and extensive hashtags using key trending phrases. These hashtags often reflect the ‘tropes’ of the text and the ever-evolving dictionary of digital language – think #EnemiesToLovers or #Bookish. Creatively edited and high-quality videos perform well. Viral formats include unboxing videos, bookshop sightings and celebrity casting speculation. Engagement, through comments, duets and community interaction, builds strong reader–author relationships and helps to foster literary discussions.

BookTok has reversed low-readership trends in younger people. A 2022 study reported that 48% of TikTok users read more books as a direct result of BookTok. With emphasis placed on community, readers are able to find inclusive, interactive spaces in a digital landscape that is increasingly volatile. Through light-hearted and judgement-free discussions, readers can share their views and recommendations in a non-academic environment, challenging hierarchical structures and ‘genre elitism’ by celebrating genres such as romance and fantasy, which have historically been labelled as ‘unintellectual’. By encouraging participation, BookTok has been credited for demystifying reading and allowing readers to branch out. Independent bookshops and libraries have adapted to the platform’s influence by putting on themed events and organising reading challenges based on trending titles, reinforcing reading as a communal, social act. Sub-communities additionally help to spotlight marginalised authors and pave the way for niche genres. 

Crucially, its impact is not limited to just contemporary fiction. BookTok is reviving publishing backlists, and giving previously unsung novels their time in the spotlight. Colleen Hoover’s It Ends With Us, originally published in 2016, was relatively unknown until BookTok catapulted it to become the best-selling adult fiction book of 2021. As of 2024 the novel had sold over 10 million copies, and it’s even listed on Amazon as ‘It Ends With Us: TikTok made me buy it!’ A resurgence of a ‘ark academia’ trope led to renewed interest in literary fiction such as Jane Austen’s Pride and Prejudice (which won TikTok’s ‘Best BookTok Revival’ award in 2023), Donna Tartt’s The Secret History and Mary Shelley’s Frankenstein. Publishers have capitalised on this by launching re-editions of classic texts and creating collectible sets. Where the revival of older literature may be discussed in TikTok jargon, algospeak, and perhaps lack a critical rigour, it nonetheless serves as a meaningful entryway for new readers to engage in historically important literature.

Despite its many positives, BookTok is not without criticism. The platform’s preference for formulaic, trope-driven narratives often compromises literary quality. Genres like romance and fantasy dominate, meaning that diverse voices can be marginalised. And as publishers chase marketability, some worry that there is a risk of authors writing accordingly, with consumption and digestibility in mind. Additionally, there are concerns regarding transparency, with content creators not disclosing paid partnerships, leading to an ethical debate about authentic promotion and how to ensure the emergence of niche voices and unconventional narratives. 

BookTok is, however, more than just a passing trend, and it has shifted the way in which people are reading, talking about and sharing book recommendations. It has significantly helped make reading more accessible and has fostered emotional relationships for those seeking community. Whether it is new novels or backlisted works, its impact has been immeasurable, for both readers’ enjoyment and authors’ success. If there are ways to redress issues with a lack of representation and diversity, and ensure that literary creativity and innovation is celebrated, BookTok can keep transforming the literary sphere in fiery and meaningful ways and ensure the space remains inclusive and enjoyable.
