By 2026, Sierra Leone’s digital advertising market is expected to reach USD 15 million, reflecting steady growth driven by increasing internet adoption and mobile phone usage. The mobile advertising segment dominates, accounting for approximately 70% of total ad spend, as mobile devices remain the primary access point for online content. Social media platforms continue to expand their reach, with around 2.5 million active users fueling targeted advertising opportunities.
Despite the growth, internet penetration remains at about 35%, indicating significant room for expansion. As digital infrastructure improves and smartphone adoption accelerates, digital ad spending per capita will likely increase, supporting broader economic development and digital literacy. The evolving landscape presents opportunities for both local and international advertisers to engage Sierra Leone’s expanding online audience.
