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 older cohorts simply do not. In the UK, 94% of 15 to 24-year-olds use social media services every month, according to Ofcom’s Media Nations 2025 report, well above the rate for older age groups. For SMEs in Northern Ireland, Ireland, and across the UK, understanding where Gen Z spends its time online and what it does there is the foundation of any serious content marketing or platform strategy, not optional background reading.

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. Knowing what to do with it, and which of your own channels need to change first, 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 global report. That figure is considerably higher than that of Millennials and sits well above the global average across all age groups. A Morning Consult study found that 35% of Gen Z spend more than four hours daily on social platforms, and over 60% report they can’t go more than an hour without checking their phone, according to YPulse.

The UK picture confirms the same pattern with more current, local detail. 98% of Gen Z in the UK were using social media as of September 2024, according to Statista, with Millennials close behind at 97%, Gen X at 92%, and Baby Boomers at 86%. Adoption differences between generations have narrowed. What hasn’t narrowed is the percentage of Gen Z on social media relative to time spent and purpose, which is where the real gap between generations lives.

The time-spent data is also split by activity type. Gen Z is not only consuming; it’s watching, creating, commenting, and searching. The same platforms that serve as entertainment hubs now function as discovery engines. Ofcom’s Adults’ Media Use and Attitudes Report found that 43% of UK consumers use social media platforms to search online at least once a day, and 34% use video-sharing platforms like TikTok to search daily, with younger UK users more likely than average to do this. When a Gen Z user wants to find a restaurant, a product, or a service provider, a growing number of users start their search on TikTok or YouTube rather than Google. For any SME investing in SEO and content, that behavioural shift has direct implications for where and how you publish, and it’s exactly the kind of signal that should feed into a proper digital marketing strategy audit rather than a one-off social post.

Which Social Media Platforms Does Gen Z Actually Use?

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

The UK figures tell a slightly different but related story. YouTube is the most-used platform among users aged 18 to 34 in the UK, with an average of 88 minutes spent daily, ahead of TikTok at 49 minutes and Instagram at 35 minutes. WhatsApp actually has the highest overall reach across all UK age groups when messaging apps are included, but that’s a different metric from time spent on content platforms, and it doesn’t change where younger users’ attention and buying decisions happen.

YouTube’s dominance is not purely entertainment-driven. Pew Research Centre found that 69% of Gen Z use YouTube specifically for learning, which 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. This is squarely video production territory, and it’s worth watching how a UK agency approaches short-form and long-form video output side by side.

TikTok’s position is interesting for a different reason. Among UK and Irish businesses, it’s often dismissed as a platform for teenagers. The data doesn’t support that dismissal. Gen Z now uses TikTok as a search engine, entering queries they would previously have typed into Google, and Sprout Social’s Q2 2025 Pulse Survey found that Gen Z users were more likely to use social search over traditional search engines, with 41% saying social is the first place they turn to when looking for information online, whether that’s product reviews or how-to tutorials. 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 haven’t taken seriously yet. They’re a natural extension of a YouTube marketing plan rather than a separate channel to manage from scratch.

Instagram retains a strong position among Gen Z, particularly for product discovery and influencer-driven purchases. Its strength lies in visual brand building rather than search, making it a better fit for businesses with high-quality imagery or a strong aesthetic identity. If your own site still runs on templates that weren’t built with mobile-first video embeds and fast load times in mind, that’s worth fixing before you put budget into platforms your web design hasn’t caught up with; a slow, desktop-first site undermines every click a Gen Z shopper sends it from TikTok or Instagram. Website development work on speed and mobile layout should sit alongside, not after, any social content push.

ProfileTree’s content marketing service helps SMEs identify which platforms align with their audience and build a publishing strategy that doesn’t 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 and Online Communities

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, 53% create content to connect with others who share their interests, and 52% create content for entertainment and humour, all according to YPulse research. Gen Z online communities matter here too. Discord’s growth among this age group isn’t just about gaming; interest-based communities on Discord, subreddits, and niche Facebook Groups are increasingly where product opinions form before they ever reach a public feed. That’s a slower, harder channel for a brand to enter, but it’s worth understanding if your audience skews younger; our piece on online community statistics covers this in more depth for SME marketing teams building a community strategy from scratch.

For businesses, this has two direct applications. First, Gen Z employees and customers are potential content collaborators. User-generated content, 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 suggests the format you need to produce. Static imagery and text-based posts haven’t 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 this shift, helping SMEs produce short-form content that stands out in a feed dominated by amateur footage, without the overhead of a full broadcast production. For services or products that are genuinely difficult to film, whether that’s a B2B software workflow or a manufacturing process, animation is often a better fit than live footage, and it solves the same “show, don’t tell” problem Gen Z content demands.

“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

Purchasing data on Gen Z is among 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 operates differently here than it does with older cohorts.

The pattern is consistent: Gen Z trusts people over brands, specific, relatable voices over celebrity endorsements, and content that looks like it was made by a real person over content that looks like an advert. That trust dynamic also extends to where a business is listed and reviewed; if your listings on Google Business Profile and other directories are thin or inconsistent, you’re undercutting the very trust signals Gen Z looks for before they’ll even click. Our guide to free business listing sites for the UK and Ireland covers the basics you should get right first.

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 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, including getting basics like video dimensions and aspect ratios right across platforms; our Twitter dimensions guide is a useful quick reference if you’re repurposing the same video across multiple channels.

Gen Z, LinkedIn and the Workplace

Most discussion of Gen Z and social media focuses on lifestyle and shopping, but this generation is also entering the workforce, and its professional habits are underrepresented in much of the coverage. LinkedIn use among Gen Z is growing, particularly for career content and B2B discovery. It isn’t their primary platform, but it’s increasingly relevant for professional services businesses recruiting or marketing to a younger workforce.

The practical implication for SMEs is twofold. First, if you’re recruiting Gen Z talent, a stale or inactive LinkedIn presence sends the wrong signal before a candidate even applies; the same authenticity standards that apply to TikTok apply here too. Second, marketing managers who built their skills on Facebook ads and email campaigns often haven’t been trained on how Gen Z search and discovery actually work across platforms. That’s less a budget problem than a knowledge gap, and it’s the specific gap ProfileTree’s digital marketing training programme is built to close, covering social strategy, short-form video, and content marketing for teams who need to catch up quickly. If you’re weighing up whether to build this skill in-house or bring in outside support, our piece on social media jobs, UK costs and when to outsource walks through that decision in more detail.

What This Means for Your SME Marketing Strategy

The statistics above indicate several practical shifts for any SME seeking to reach Gen Z audiences.

Prioritise video, especially short-form. YouTube and TikTok dominate Gen Z attention, and the UK-specific viewing figures back this up. 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, and the Ofcom data above confirms this isn’t a niche behaviour in the UK. 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 isn’t 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, and this is exactly the kind of prioritisation decision a proper digital marketing strategy audit is designed to answer, rather than guessing.

Use AI tools to keep pace with content volume, not to replace judgement. Short-form video demands a volume of output that stretches most small marketing teams. AI-assisted tools can help repurpose long-form footage into clips, draft caption variations, and speed up editing, but they don’t replace a clear content strategy or a real understanding of your audience. This is where AI implementation and training for existing teams tends to pay off faster than hiring for a brand-new role.

Invest in digital training for your team. The biggest gap for most SMEs isn’t budget; it’s knowledge. Once your video and platform strategy is in place, the next question is usually how you measure whether it’s actually working; our guide to what a KPI is and how to measure digital marketing performance is a useful next step for teams setting up reporting for the first time. It’s also worth looking at how community-first brands outside the typical SME sector approach this; the UGC and community-engagement principles covered in our social media strategy guide for non-profits translate directly to small businesses operating on limited budgets.

The transition from a broadcast marketing mindset to a community-participation mindset isn’t straightforward, and it doesn’t happen overnight. But the data trend is clear: it points in the same direction whether you’re looking at UK-specific figures from Ofcom and Statista or broader global research. For a wider view of where these platform habits are heading next, our Social Media 2026 Trends guide for Irish and UK businesses picks up where this article leaves off.

Where This Leaves UK and Irish SMEs

Gen Z watches more video, trusts peers over adverts, and searches on TikTok instead of Google. That quietly rules out a Facebook-first content plan, a desktop-first website, or a marketing team still judging success by likes.

The SMEs that benefit most won’t necessarily have the biggest budgets. A small team posting real, consistent video often earns more trust with this audience than a bigger brand’s polished ads. The gap that matters is knowledge and consistency, not spending.

The practical next step: pick one platform where your audience already is, commit to it properly, and measure results before spreading effort across three or four channels at once.
