What Is Booktok?

Basically, BookTok is the part of TikTok where book lovers hang out. It’s a massive community of readers (and some authors) who post short videos recommending, reviewing, or just fangirling/fanboying over books. Most of the time, these videos use the hashtag #BookTok.

It all started when someone casually shared their favorite books, and it just exploded from there. Now, it’s huge — mostly dominated by teens and women, with a focus on genres like romance, young adult fiction, fantasy, and the like.

Why is it a big deal? Because it actually sells books. Like, a lot. If a book goes viral on BookTok, you can bet it’ll end up on bestseller lists — even if it was published years ago. Colleen Hoover’s It Ends With Us is a perfect example. The book came out in 2016, but thanks to BookTok, it sold over 770k copies in 2021 alone. Same with They Both Die at the End and The Song of Achilles — both older books that blew up because of TikTok.

Publishers and bookstores have caught on, too. They watch what’s trending on BookTok to know what people are into. Since 2020, YA and adult fiction have seen huge spikes in sales, with overall print book sales in the U.S. growing by around 9%, largely thanks to BookTok.

As a reader, it’s a goldmine. You get quick, relatable recs, short summaries, and tons of "If you liked X, read Y" style videos. Super helpful if you're building your TBR list or just looking for your next obsession.

BookTok is changing the way books get discovered and hyped — and it’s not slowing down anytime soon.

BookTok is a community on TikTok where people share short videos about books — everything from emotional reactions and spicy takes to recommendations, aesthetics, and reviews. It’s not polished or formal like traditional book reviews; it’s chaotic, personal, and often hilarious. Most of it lives under the hashtag #BookTok, and if you’ve ever seen a video of someone crying over a fictional character or clutching a book like their life depends on it — that’s probably BookTok.

It started pretty organically. A few users just began posting videos about their favorite books, and other readers started joining in. Then certain titles began to blow up — like *It Ends With Us* by Colleen Hoover, which got a second life years after it was published, purely because people kept talking about it on TikTok. The same thing happened with *The Song of Achilles* and *They Both Die at the End*. These weren’t new releases, but BookTok sent them rocketing back up bestseller lists.

The reason BookTok works so well is because it feels authentic. It’s not publishers pushing ads — it’s real readers reacting to books they genuinely love (or hate, which can also be entertaining). The content is super snackable, and TikTok’s algorithm is great at delivering niche content to the exact right audience. So if you're into fantasy with morally gray characters, or heartbreaking queer romances, chances are TikTok will serve that to you — with dramatic music and crying.

BookTok’s influence has only gotten stronger. Publishers are paying attention, bookstores now have “TikTok made me buy it” sections, and some authors are literally launching their careers through the platform. The community has helped spike book sales across genres, especially romance, young adult, and fantasy. Even adult fiction saw a big boost because of viral videos.

Looking ahead, it doesn’t seem like BookTok is going anywhere. If anything, it’s becoming a bigger part of how books are marketed and discovered. More authors are creating content, more books are being written with the “BookTok vibe” in mind, and more readers are finding their next obsession through it. It's messy and unpredictable — but it's also kind of amazing to see a platform like TikTok getting people genuinely excited about reading again.

BookTok is a part of TikTok where people talk about books — sharing reviews, reactions, and recommendations in fun, emotional, and super relatable videos.

Now, even bookstores and publishers follow BookTok trends. It’s especially big for romance, YA, and fantasy. More and more authors are joining too. Basically, BookTok makes reading feel cool and personal — and it’s not slowing down anytime soon.
