The book market is similar to the music industry, except that it is far behind from a digital marketing perspective. Few publishing houses have real SMO strategies in place to launch and defend their authors’ projects in the short, medium and long term. Apart from PR campaigns, their strategy most often boils down to waiting for a book to stand out from the pack of annual volumes published, thanks to the writers’ greater or lesser notoriety at the time of their books’ release (social networks, media relays, etc.), whose viral effect quickly fades due to the lack of SEO/SEA/SMO actions, in the age of digital.
