South Korea’s digital landscape is one of the most dynamic in the world. With near-total internet penetration and some of the fastest connection speeds globally, it’s no surprise that the way Koreans search online tells us a lot about their culture, preferences, and even values.

But behind every search lies a deeper story about lifestyle, intent, and culture—and those stories shift significantly across age groups.

At Charlesworth, we’re constantly exploring how digital behaviours shape the way people interact with content, platforms, and brands. Whether you’re a marketer, business owner, or just someone curious about Korean digital behavior, understanding these patterns could be your golden ticket to better engagement.

The Big Three: Naver, YouTube, and Instagram

Before diving into generational insights, let’s talk about Korea’s most-used platforms:

• Naver is Korea’s homegrown search engine. More than just a search tool, it’s a comprehensive content ecosystem combining blogs, forums, news, shopping, and real-time trends. With a 70%+ search engine market share, it remains a trusted resource across age groups.
• YouTube has become much more than an entertainment platform. It’s where Koreans go to learn, laugh, and research. Over 90% of Koreans aged 16–59 use it regularly.
• Instagram serves as a discovery platform—especially for food, fashion, beauty, and travel. For younger generations, it’s where search begins visually.

While these platforms are used by all generations, how they’re used varies widely.

20s: Trend-Driven and Visually Oriented

Koreans in their 20s—Gen Z and younger millennials—are digital natives. For them, search is about discovery and expression.

• YouTube is their go-to platform, with top searches around gaming, beauty reviews, and travel content.
• Instagram functions as a visual search engine. According to data from OpenSurvey, 40% of women in their 20s search IG for food content, while men are split between travel, fashion, and celebrity culture.
• Naver still has a presence, especially for more structured searches like movie reviews or travel planning.

Key takeaway: To reach this group, brands should invest in short-form video, authentic influencer collaborations, and visually-driven content across IG and YouTube Shorts.

30s: Purposeful, Practical, and Lifestyle-Oriented

In their 30s, most Koreans are navigating career growth, financial stability, and major life decisions. Their search habits reflect these priorities.

• Naver becomes a hub for information—covering everything from investment advice and real estate to travel planning and cooking.
• YouTube serves dual purposes: part entertainment, part research. Product comparisons, financial tutorials, and family-oriented content perform well in this demographic.
• Instagram is used more selectively, with 38% of women in this age group searching for fashion and travel inspiration. Male users tend to engage with entertainment and celebrity accounts.

Key takeaway: This audience values trustworthy, useful content. Brands should focus on Naver blog SEO, in-depth product reviews, and thoughtful Instagram content that adds real value.

40s: Trust-Oriented and Community-Focused

For Koreans in their 40s, digital platforms serve as a source of both information and entertainment. But unlike younger users, this generation favours familiarity and credibility.

• Naver is the preferred platform, with searches focused on news, politics, online shopping, and lifestyle content. A 2024 study found that 40% of men in this group prioritise political and social issue content.
• YouTube sees strong engagement—especially with dramas, music performances, and food-related content. Women in their 40s are particularly drawn to cooking channels and celebrity family vlogs.
• Instagram plays a smaller role, but it’s still relevant. Males follow celebrity content (52%) while females explore food (41%) and beauty (37%).

Key takeaway: For older audiences, trust is everything. Long-form blog content on Naver, consistent YouTube programming, and credible voices will resonate far more than fast-moving trends.
