TikTok expands #BookTok bestseller lists to six European markets after driving €800M in publishing revenue

TikTok is expanding its #BookTok bestseller lists to Germany, the UK, Spain, Italy, Austria, and Switzerland, combining TikTok platform insights with NielsenIQ BookData sales figures to produce a monthly overview of book trends driven by the app's community. The lists, originally launched in Germany in 2023 in partnership with Media Control, build on a year in which more than 50 million books recommended by the #BookTok community were sold across Europe, with TikTok claiming to have generated €800M in revenue for the publishing industry in 2025. Alongside the list expansion, TikTok is also rolling out its in-store #BookTok bestseller sticker program to the UK, Italy, and Spain, giving approved titles a physical retail signal tied to their performance on the platform.
