Human Discovery Might Be Overtaking the Algorithm
As AI and algorithms increasingly dictate what we read, readers are fighting back and a new culture of digital word-of-mouth is reshaping publishing and proving that human recommendations still carry weight.
For years, algorithmic patterns such as Amazon’s ‘recommended reads’ and curated bestseller lists that have been encoded by popularity data have held an unprecedented grip on how books are being discovered. However, a quiet shift is underway. Readers are beginning to reclaim that power for themselves and the publishing industry is paying attention.
While such a motioning towards human intimacy unfolds, it does so in a way that transforms human interpersonality. Importantly, AI continues to shape such a landscape. I am not talking about conversations held necessarily over a coffee, but word of mouth re-imagined for the digital age. On TikTok emotional reactions, comments, and retellings of books are driving readers to shelves in ways no algorithm predicted. On YouTube, or Booktube longer, more considered discussions are deepening the same impulse. Both platforms speak to something timeless. This is the innate human desire to share a story that moved them, and for those to seek out an encounter with such a reflection.
Some name this shift the ‘democratisation’ of influence in the publishing world. Where gatekeepers, critics and publicists once charted the obvious trends in reading, now readers themselves are shaping the landscape. This appeal to authenticity is reckoning a powerful impact on book sales. Trust and human intimacy has become currency. A genuine, unsponsored recommendation surfaces as a potential reaction to skepticism many feel towards the algorithmic world that drives our lifestyles. Targeted ads, although powerful in leveraging visibility and exposure, are better alongside social recognition. While marketing and advertising has operated a time-old foothold in the publishing world, it is unprecedented the way in which readers are consolidating and aligning their trust in books.
The impact is measurable. In Europe alone, over 50 million BookTok-recommended titles were sold in 2025, generating around €800 million in revenue. More than a third of 16 to 39 year-olds now report discovering books through TikTok. Publishers are responding, monitoring social hashtags to identify emerging trends, partnering with creators for advance reading copies, and investing in influencer relationships over traditional advertising campaigns.
Interpersonal online trust is emerging as an important player for book sales, and even overriding the influence of critics and the determinism of algorithmic curation - that encoded logic ranking what is popular over what may be meaningful. With such an immense wealth of titles available online, readers are turning to their fellow readers, virtually rather than in-person, for recommendations. The impact of such ‘conversational discovery’ online is tangible. For example, such digital social communities of readers have issued a popular return to backlist titles. Vintage books re-‘discovered’ by influencers are surging in ways driven by a hunger for nostalgic, resonant reads. In this way, community- powered discovery is shaping book sales in ways which algorithms simply may not be able to anticipate.
Both TikTok and BookTube complement this overarching orientation towards something personal yet virtual, demonstrating how emotional connection remains the truest currency for how we choose books from the shelves. Alongside AI strategies such as SEO and the emerging field of Generative Engine Optimisation, the role of humans and their love for connection through this digital world remains paramount for book success. These are not competing forces; they are, at their most effective, deeply intertwined.
With flourishing online communities dedicated to every conceivable genre and readership, it is vital that the publishing industry remains sensitive to such an evolving culture of readerships. Automated, encoded popularity data drives online sales, yet risks falling to the backfoot if it is not paired with a meaningful attentiveness to what is stirring on social platforms; the unquantifiable consensus that humans cannot seem to ignore, and are always in the end emotionally captured by.
For the publishing world, this is both a relevant challenge and an invitation. The readers are already talking, but the question is whether we are listening.
