Social Media Marketing

Facebook remains central for readers who organize their lives around family, work, and community. Globally, the platform now serves roughly three billion monthly active users. In the United States, about seven in ten adults use Facebook, and it is one of the only networks where a clear majority of adults in every band from thirty through the late sixties are still active.

X no longer functions as a primary sales engine for most books, but it remains unusually dense where media power sits. Global estimates in late 2025 place X in the range of roughly six hundred million monthly active users, which keeps it among the largest social platforms despite a smaller footprint than Facebook, Instagram, TikTok, or YouTube.

LinkedIn serves a specific segment of authors better than any other platform, specifically business, professional, and academic writers, as well as authors of prescriptive nonfiction in leadership, health, education, finance, and adjacent fields. The network now reaches well over a billion registered members, with most active users concentrated in the twenty-five to thirty-four age band and a significant share in early and mid-career roles.
