How Do Authors Use TikTok?

TikTok and BookTok in context

BookTok is not an official feature of TikTok; it is simply the name commonly given to the loose community of readers, and some authors, who post and watch short videos about books. It is strongest in certain fiction genres, and less established, or largely absent, in others, so its relevance depends heavily on what you write.

Reader fit

Before investing time in TikTok, it is worth checking whether readers of your specific genre or subject are genuinely active there. Some genres, particularly romance, fantasy, young adult and some crime and thriller fiction, have a visibly active presence; many non-fiction subjects and some fiction genres do not, and time may be better spent elsewhere for those books.

Video ideas

Common approaches include short readings, reactions to reader questions, "books like this" style comparisons, character introductions, behind-the-scenes writing content, and honest commentary on the writing or publishing process. Content that shares something a viewer finds genuinely interesting or entertaining tends to travel further than content that only promotes.

Hooks

Short-form video generally needs to establish interest within the first few seconds, since viewers scroll on quickly if nothing catches their attention. A clear, specific opening line or visual, rather than a slow introduction, tends to keep more viewers watching.

Authenticity

TikTok’s culture generally favours unpolished, direct video over heavily produced content. Authors who present as genuine and a little informal tend to do better on this platform than those who bring a highly produced, promotional style better suited elsewhere.

Trends

Trending sounds, formats and challenges can occasionally help a video reach further, but trends move quickly and a book-specific angle needs to be found for a trend to make sense rather than feeling forced. Chasing every trend is rarely sustainable; using the occasional one that genuinely fits is more realistic.

Search and discovery

TikTok is increasingly used as a search tool by some users, particularly for recommendations and reviews, alongside its algorithm-driven feed. Clear, descriptive captions and on-screen text can help a video surface in relevant searches, though exact mechanics change and are worth checking against TikTok’s current guidance.

Comments

Replying to comments, including with short video replies where the platform supports this, tends to extend a video’s reach and builds a more genuine connection with viewers than posting and moving on without engaging further.

Creator collaboration

Sending a book to an established BookTok creator whose usual content genuinely matches your genre can occasionally lead to a video about your book, though this cannot be guaranteed or bought outright without disclosure, and most creators have their own review policies worth checking first.

Launch

A book launch is a reasonable moment to post more actively, sharing the cover reveal, countdown and early reactions, but relying on TikTok alone around launch is risky given how unpredictable reach on the platform can be; it works best as one part of a wider plan.

Backlist

One notable feature of BookTok activity is that it has sometimes brought renewed attention to older, previously published books, not only new releases. This means ongoing TikTok activity can be worth maintaining for backlist titles, not only around a new launch.

Series

For series authors, TikTok content that helps new readers find where to start, or that builds anticipation for a coming instalment, can support the whole series rather than a single book in isolation.

Analytics

TikTok’s built-in analytics, available to certain account types at the time of writing, show metrics such as views, watch time and engagement, which are more useful for understanding what content resonates than follower count alone. Check the platform’s current analytics tools directly, since availability and presentation change.

Platform volatility

TikTok’s features, algorithm and even its regulatory status in some regions have changed and been contested over time. This is a genuine risk for any author who treats the platform as their only or primary marketing channel, and is a reason to keep building channels you control alongside it.

Why virality is not a plan

A small number of books have received unusually large, largely unplanned attention through BookTok, and these examples tend to be the ones authors hear about. They are not a reliable template, because the same content style and effort applied to another book will not necessarily produce the same result. Treating "going viral" as a strategy sets an author up for disappointment; treating consistent, genuine content as the actual strategy, with occasional wider reach as a possible bonus, is more realistic.

Linking back to an owned audience

Wherever TikTok’s features allow it, pointing interested viewers towards a website, an email list or a specific place to learn more about the book converts fleeting attention on a rented platform into a connection you can maintain independently of TikTok’s own algorithm or future availability.

Common mistakes

• Treating TikTok as a guaranteed sales channel. Expecting a specific video, or the platform generally, to reliably produce sales sets an author up for disappointment; reach and outcomes vary widely.
• Ignoring genre fit. Posting on TikTok without checking whether your specific genre or subject has an active audience there can mean effort spent where readers simply are not.
• Over-producing content. Heavily polished, clearly scripted video often performs less well on this platform than genuine, direct content.
• Chasing every trend. Forcing a book-specific angle onto every trending format, whether or not it fits, tends to feel forced and unsustainable.
• Relying on TikTok alone. Building a presence only on TikTok, without a website or email list, leaves an author exposed if the platform or its algorithm changes.
