Publishers, booksellers and online influencers use a range of marketing techniques to steer readers towards particular books, especially during the competitive autumn sales period. The article argues that buying decisions are shaped well before a customer starts reading, through cover design, shelf placement, blurbs, supermarket buyers and social-media recommendations.
