Gen Z Social Media Statistics: What Every SME Marketer Needs to Know

Gen Z social media statistics tell a clear story for any business trying to reach an audience under 27: this generation does not just scroll, it shops, searches, and makes purchasing decisions through social platforms in ways that older cohorts simply do not. For SMEs in Northern Ireland, Ireland, and across the UK, understanding where Gen Z spends its time online and what it does there is no longer optional background reading; it’s the foundation of any serious content or paid social strategy.

ProfileTree, a Belfast-based digital marketing agency, works with SMEs across the UK and Ireland who are grappling with exactly this shift. The data is clear, but knowing what to do with it is where most businesses fall short.

How Much Time Does Gen Z Spend on Social Media?

The average Gen Z user spends 3 hours and 19 minutes on social media every day, according to We Are Social and Hootsuite’s 2022 global report. That figure is considerably higher than that of Millennials and sits well above the global average across all age groups.

It doesn’t stop there. A Morning Consult study found that 35% of Gen Z spend more than four hours daily on social platforms. Over 60% report they can’t go more than an hour without checking their phone, according to YPulse. For marketers, this volume of daily exposure means the question is never whether Gen Z will see social content; it’s whether they will stop on yours.

The time spent data is also split by activity type. Gen Z is not only consuming; it is watching, creating, commenting, and searching. The same platforms that serve as entertainment hubs now function as discovery engines. When a Gen Z user wants to find a restaurant, a product, or a service provider, a growing number start the search on TikTok or YouTube rather than Google. For any SME investing in SEO and content marketing, that behavioural shift has direct implications for where and how you publish.

Which Platforms Does Gen Z Actually Use?

Understanding platform preferences by generation is one of the most actionable pieces of data available to any marketing team. The numbers below, drawn from comScore and Morning Consult research, show where Gen Z’s attention actually sits.

YouTube sits at the top, and its dominance is not purely entertainment-driven. Pew Research Centre found that 69% of Gen Z use YouTube specifically for learning. That makes it the most valuable platform for any business producing educational content: tutorials, explainer videos, product walkthroughs, or behind-the-scenes content showing how a service works.

TikTok’s position is interesting for a different reason. Among UK and Irish businesses, it’s often dismissed as a teenage platform. The data does not support that dismissal. Gen Z now uses TikTok as a search engine, entering queries they would previously have typed into Google. For SMEs with strong visual or demonstrable products and services, TikTok and YouTube Shorts represent a significant organic discovery opportunity that most competitors in their sector have not yet taken seriously.

Instagram retains a strong position among Gen Z, particularly for product discovery and influencer-driven purchases. Its strength is in visual brand building rather than search, which makes it a better fit for businesses with high-quality imagery or a strong aesthetic identity.

ProfileTree’s content marketing service helps SMEs identify which platforms align with their audience and build a publishing strategy that does not spread limited resources across every channel. The right choice for a Belfast hospitality business differs from the right choice for a Derry-based professional services firm.

Gen Z as Content Creators

One of the most significant findings in Gen Z social media statistics is that this generation doesn’t draw a clean line between consuming and creating. According to YPulse, 63% of Gen Z create and share content online. Sprout Social found that 54% specifically create video content, while 47% regularly share photos.

Their motivations are worth understanding:

• 61% use social media for creative self-expression (YPulse)
• 53% create content to connect with others who share their interests (YPulse)
• 52% create content for entertainment and humour (YPulse)

For businesses, this has two direct applications. First, Gen Z employees and customers are potential content collaborators. User-generated content (UGC), meaning real customers posting about real experiences, carries significantly more weight with a Gen Z audience than polished brand advertising. A Belfast restaurant that encourages customers to post their food on TikTok is building social proof in a format that actually converts with this demographic.

Second, the dominance of video creation tells you something about the format you need to produce. Static imagery and text-based posts have not disappeared, but for Gen Z-facing brands, short-form video is the baseline, not the premium option. ProfileTree’s video production service is built around exactly this shift, helping SMEs produce short-form content at a quality level that stands out in a feed dominated by amateur footage, without the overhead of a full broadcast production.

“As Gen Z increasingly turns to platforms like TikTok and YouTube as their primary discovery tools, businesses that invest in genuine, high-quality video content will reach audiences that traditional advertising simply cannot access,” says Ciaran Connolly, founder of ProfileTree.

How Gen Z Uses Social Media to Shop

The purchasing data on Gen Z is one of the most commercially significant findings in this space. According to The Harris Poll, 87% of Gen Z say social media directly influences their purchasing decisions. McKinsey found that over 60% have discovered new products through social platforms, with TikTok and Instagram cited as the primary discovery channels.

Trust is the deciding factor in the Gen Z purchase journey, and it works differently here than it does with older cohorts:

The pattern is consistent: Gen Z trusts people over brands. It trusts specific, relatable voices over celebrity endorsements. And it trusts content that looks like it was made by a real person more than content that looks like an advert.

For SMEs, this is both a challenge and an opportunity. The challenge is that traditional paid advertising formats perform poorly with this audience. The opportunity is that authentic, community-driven content (the kind that most large brands struggle to produce credibly) is exactly what smaller businesses can do well.

An SME in Northern Ireland that builds a genuine following on TikTok, responds to comments, posts content showing the real people behind the business, and encourages customers to share their experiences is executing a strategy that aligns directly with how Gen Z makes decisions. That doesn’t require a large budget. It requires consistency and the right content approach.

What This Means for Your Marketing Strategy

The statistics above point to five practical shifts for any SME trying to reach Gen Z audiences.

Prioritise video, especially short-form.YouTube and TikTok dominate Gen Z attention. If your business has no video presence, you’re invisible to a significant portion of the under-27 demographic. Start with one platform, produce content consistently, and build from there.

Treat social platforms as search engines. Gen Z uses TikTok and YouTube to search for recommendations, reviews, and how-to content. Optimising your video titles, descriptions, and captions for the terms your audience searches matters as much as Google SEO now.

Build UGC into your strategy. Encouraging customers to post about their experience is not a nice-to-have. For Gen Z audiences, peer content is more persuasive than anything you produce yourself. Make it easy: create a branded hashtag, feature customer posts in your own content, and respond to every comment.

Match the platform to the product. YouTube works for educational and longer-consideration purchases. TikTok works for discovery and impulse buys. Instagram works for visual brand building. Spreading thin across all three is worse than going deep on one.

Invest in digital training for your team. The biggest gap for most SMEs is not budget; it’s knowledge. Marketing managers who built their skills on Facebook ads and email campaigns need to understand how Gen Z search and discovery actually work. ProfileTree’s digital training programme covers social strategy, short-form video, and content marketing for exactly this purpose.

The transition from a broadcast marketing mindset to a community-participation mindset is not straightforward, and it doesn’t happen overnight. But the data on Gen Z social media usage makes the direction clear.
