Where Should You Focus Your Social Media Marketing in 2025?
Social Media Marketing succeeds when you meet your audience on the platforms they use most. By segmenting users by age, marketers can allocate budget more effectively, choosing Instagram for young adults and Facebook for Boomers. In 2025, 65% of the global population (over 5.31 billion users) engages with social networks across an average of seven platforms monthly. This guide pairs data-backed insights with our downloadable chart, helping you pinpoint which channels to prioritise for each age bracket, from under 18s to 55+. Let’s dive into where your customers really are online.

In 2025, social media isn’t one-size-fits-all. Different age groups gravitate toward different platforms, and knowing where your target audience hangs out is key to a successful marketing strategy. Social media usage is now near-ubiquitous – 5.31 billion people (about 65% of the world’s population) use social media and the typical user juggles around 7 platforms per month. But preferences vary widely by age. Younger audiences overwhelmingly favor Instagram for daily stories and shopping, while older generations spend most time on Facebook and WhatsApp groups.
