How To Use Trending Hashtags For BookTok To Increase Book Sales?

I'm kinda skeptical of the whole 'use trends to sell' mentality, honestly. Feels exploitative if not done right. What works, from what I've watched, is when the trend serves the book, not the other way around. You can't just slap any book onto a popular sound and expect magic. The connection has to be real, even if it's loose or humorous. Like, that 'Oh no, oh no no no' sound was huge for books with disastrous plots or characters making terrible decisions. That makes sense. But forcing a serene literary novel into a hyper dance trend? It looks desperate. The best practitioners treat trends like a language – they use them to say something true about the reading experience. It's less about the immediate click and more about building a recognizable, relatable brand around your taste. That's what builds lasting reader trust, and that's what sells books over time, not just one hot video.

Okay so this might sound a bit counter-intuitive, but I feel like chasing every single trending sound or dance is actually a great way to burn out without moving copies. The hashtags that usually connect for books aren't the super broad ones everyone's using, but the niche ones that speak to a specific reader vibe. Like, '#cottagecorebooks' did way more for my buddy's self-pub fantasy than '#booktok' ever did. It's about matching the aesthetic of the trend to the aesthetic of your book. You see a cozy, autumn-themed trend popping off? That's your signal to push your mystery set in a small town with lots of bakeries and knitwear. You gotta be a translator, turning visual/audio trends into reading moods.

Also, authenticity gets rewarded way more than slick ads. I've seen authors try to force their book into a trend with a super polished clip and it just... flops. The videos that work feel like someone genuinely sharing a hyper-specific thought. 'Books that feel like this trend' is a stronger angle than 'buy my book.' Show a stack with your cover in it, do a 'blinded by the trend' pick where you judge books by vibes alone, use the trend to ask a question ('would this character survive this scenario?'). It creates a conversation instead of a sales pitch. My most successful reel ever was just me using a 'tell me without telling me' audio while holding up my book next to objects that matched the core themes – it was silly, but it got people guessing in the comments, and that algorithm boost is everything.

The real sales bump often comes later, not from the viral hit itself, but from the sustained, slower content that follows. That initial spike gets eyes on your profile, and then your next ten videos that are more straightforward reviews or read-alongs have a bigger built-in audience. It's a funnel, honestly. You use the big, flashy trend bucket to catch attention, but you need the steady drip of solid book-focused content to actually guide people to the 'buy' link.
