Digital marketers who want to sell books are increasingly turning to the virtual places where readers cluster. This includes marketing through the major social networks (Facebook, Twitter, Pinterest, etc.), using the data mining tools available to target within those networks, as well as marketing in niches and online communities of readers (in some cases publishers are even building vertical communities themselves). Publishers are also increasingly turning to book- and reading-focused social sites to get the word out about their books. These vehicles carry an additional bonus in the digital age: they’re global and give publishers a one-stop opportunity to reach markets beyond their natural national audiences.
