“What is #BookTok? When someone promotes a title on #BookTok, the impact can be dramatic and long-lasting.

“What is remarkable about the app is the staying power of a book once it is working,” says Shannon DeVito, director of books at Barnes & Noble. “If there is a trending title, it’s likely it will stay trending for months and, in some cases, over a year.”

#BookTok’s influence on book sales rose throughout the fall of 2020 and beyond. Some backlist titles finding popularity there moved from selling about 50 copies per week to close to 9,000, DeVito says.”
