Meta remains one of the world’s largest digital advertising ecosystems, with 3.56 billion people using at least one of its platforms daily. Although this figure has declined slightly from the previous quarter due to disruptions in markets such as Iran and Russia, Meta continues to offer unparalleled scale for advertisers. Facebook’s audience broadly mirrors the overall internet population, while Instagram attracts a younger demographic.
Meta’s heavy investment in AI and large language models is to improve its ad targeting. Its strategy centres on developing a deeper understanding of user interests through advanced content analysis and keyword labelling, enabling more personalised advertising without significantly increasing ad volume.
From a content consumption perspective, Facebook’s role as a news platform for younger audiences has declined dramatically. In 2014, 47% of people aged 18–24 accessed news through Facebook; this has since fallen to just 16%. Instagram, however, has become increasingly important for news discovery, with 30% of 18–24-year-olds now consuming news on the platform, ahead of TikTok at 22%
What this means for Irish Advertisers
In Ireland, Meta continues to operate as a mass-reach advertising channel. Facebook and Instagram each provide access to approximately 2.6 million users, while Messenger reaches around 1.55 million. Combined, Meta’s ecosystem offers advertisers access to roughly 3.65 million adults, representing exceptional penetration within a population of approximately 5.3 million.
Audience data challenges the common perception that Instagram is primarily for younger users. The largest audience segments in Ireland are aged 25–44, consisting largely of established professionals, homeowners, parents and consumers with higher disposable incomes. These demographics are particularly valuable for sectors such as fitness, property, financial services, recruitment, business-to-business services and live events.
Meta’s commercial targeting capabilities are especially strong in Ireland. Approximately 1.9 million users fall into the “Engaged Shoppers” category, meaning they regularly interact with product advertisements, browse ecommerce websites and make online purchases.
Advertising performance data shows that the strongest sectors on Meta in Ireland include retail, ecommerce, events and fitness, fashion, beauty, sportswear and homeware brands continue to perform well, while concerts, festivals, gyms, personal trainers, Hyrox events and running clubs benefit from the platform’s visual and community-driven nature.
For 2026, creative quality and content volume are proving more important than complex audience targeting. Overall, Meta remains one of Ireland’s most powerful customer acquisition channels, particularly for ecommerce, fitness, events and lifestyle brands.
