Authors often wonder which social media platforms are best to reach their specific reader audience. The various platforms do have different demographics and content expectations, so it's important to explore and do some research to find out which platforms make the most sense for you and your book.For authors of nonfiction faith-based books and memoirs, W Publishing Group Senior Marketing Manager Katherine Hudencial recommends Instagram, Twitter (X), and blogging. Hudencial says that Instagram provides the social proof consumers are looking for through influencers. They trust their book reviews. Blogs are especially important for authors that write about parenting and faith, and Twitter (X) is important in the academic and educational spaces, which are growing areas. While Facebook can still expand an author's reach, many are moving to other platforms to amplify their voices, she says.Hudencial also reminds authors of the importance of email marketing. Your email distribution list is your "owned" audience, she says. They already follow you and are more likely to be converted into buyers. Sending email newsletters can be a great complement to your social media activity.
