The Social Media Industry in 2025: Statistics, Trends and What They Mean for Your Business

The social media industry has moved far beyond its origins as a way to stay in touch with friends. In 2025, it sits at the centre of how people discover brands, consume news, make purchasing decisions, and even build careers. From a modest 4.2 billion users in 2020, the social media industry has grown to serve more than 5 billion people globally, meaning well over half the world’s population interacts with these platforms every single day. For businesses in Northern Ireland, the UK, and Ireland, understanding where the social media industry is heading is no longer optional; it is a practical commercial necessity.

At ProfileTree, a Belfast-based web design and digital marketing agency, we work with businesses across a wide range of sectors to build strategies that turn social media presence into measurable results. The data in this report draws on verified global statistics and is contextualised for the realities of operating in the UK market.

Industry Growth 2020-2025

The scale of growth across the social media industry over the past five years has been significant, reshaping both consumer behaviour and business strategy at every level.

User Growth

The global user base has grown by roughly 20% since 2020. That trajectory is not simply about adding users in emerging markets. Penetration in mature markets like the UK has also deepened, with more older demographics joining platforms and existing users spending more time engaging with content. According to Statista, around 57.1 million people in the UK used social media in 2024, a figure expected to rise steadily through 2026.

This growth has practical consequences for businesses. A larger, more diverse user base means wider reach but also more competition for attention. Organic visibility across most platforms has declined as the user base has grown, putting pressure on businesses to invest in both quality content and paid amplification. A clear digital marketing strategy is now the starting point for any business that wants to cut through the noise rather than simply add to it.

Revenue and Market Size

The global social media industry generated approximately $251 billion in advertising revenue in 2024, up from $219 billion in 2023. That growth rate has been sustained for several consecutive years, demonstrating the depth of advertiser confidence in these platforms as commercial channels.

In the UK specifically, social media advertising spend has consistently outpaced other digital channels. Social video and Stories formats now account for the largest share of social budgets, reflecting shifts in how users consume content. Businesses that invest in structured content marketing alongside their paid spend consistently achieve better organic reach and lower cost-per-click rates over time.

Time Spent

Despite occasional headlines suggesting users are pulling back, average daily time spent on social media platforms has remained broadly stable at around 143 minutes globally. In the UK, that figure sits closer to 110 minutes per day for adults, with younger demographics spending considerably more. These platforms have, in effect, become a significant slice of daily life for a large portion of the population.

Platform Usage Statistics

Not all parts of this industry are growing at the same pace, and the competitive dynamics between platforms have shifted considerably since 2020. Understanding where audiences actually spend their time is essential before allocating any marketing resource. ProfileTree’s social media marketing services are built around this kind of platform-specific insight, matching businesses with the channels where their customers are most active.

The Major Platforms in 2025

The social media industry today is structured around a handful of dominant platforms, each serving distinct user needs.

Facebook retains around 3 billion monthly active users globally, making it the largest single platform across the major networks. In the UK, it remains the most widely used platform among adults over 35, which makes it essential for local service businesses and consumer brands targeting that demographic.

YouTube has approximately 2.5 billion monthly active users and occupies a unique position as both a search engine and a video platform. For businesses, it offers the longest content shelf life of any platform; a well-optimised video can continue generating views and website traffic for years. Our video marketing and production services are designed to help businesses create content that performs on YouTube as well as short-form platforms.

WhatsApp, with around 2 billion users, dominates private and group messaging in the UK. While not a traditional advertising platform, the broader move towards conversational commerce means WhatsApp Business is becoming a more relevant commercial tool.

Instagram has reached 2 billion monthly users and remains the primary platform for visual storytelling, influencer marketing, and product discovery. Reels have driven significant engagement growth, aligning Instagram more directly with TikTok’s strengths.

TikTok has over 1.2 billion monthly active users globally. In the UK, around 23 million people use the platform regularly. It has reshaped expectations across every major platform by establishing short-form video as the default content format for younger audiences.

LinkedIn, with approximately 1 billion members, has evolved from a job board into a B2B content platform. For professional services firms, it is increasingly the most commercially relevant network. Combining a strong LinkedIn presence with SEO services that target commercial search queries gives B2B businesses two complementary routes to qualified traffic.

Pinterest has around 465 million monthly users and retains strong utility for discovery-driven categories such as home design, fashion, and food.

X (formerly Twitter) has approximately 550 million monthly active users. Its position has become more contested since its rebranding, but it remains important for real-time news, public discourse, and reaching journalists and opinion formers.

Multi-Platform Behaviour

The average person actively uses 6.7 social platforms per month. For businesses, this means a single-platform strategy is rarely sufficient and content needs to be adapted for different formats rather than simply republished across channels.

Gen Z and the Next Wave

Gen Z spends between four and five hours daily on social media, significantly above the adult average. More importantly, Gen Z uses the social media industry differently: as a search engine, a shopping channel, and a primary source of news. For businesses trying to reach 18 to 26 year olds, understanding these behaviours is as important as the headline platform numbers. Our digital training programmes cover platform strategy for different audience segments, including how to adapt content for Gen Z versus older demographics.

Social Media Marketing in 2025

The commercial dimension of social platforms has matured considerably. What was once a largely experimental marketing channel has become a structured, measurable part of the marketing mix for businesses of all sizes.

Advertising Spend

Global social media advertising spend is projected to reach $255 billion on mobile alone by 2028. In 2024, the majority of ad investment is concentrated on Meta, YouTube, and TikTok. For UK businesses, Meta remains the dominant platform for paid reach, while TikTok is gaining ground among brands targeting younger consumers.

Cost-per-click rates have risen across most platforms over the past three years, meaning businesses need clearer conversion tracking and more precise audience targeting to maintain efficiency. Working with specialists in paid social media marketing helps avoid common budget inefficiencies and build campaigns around verified audience data.

Social Commerce

One of the most significant developments in recent years is the growth of social commerce, where users discover and purchase products without leaving the platform. Research from GlobalWebIndex found that 76% of social media users have bought something they first saw advertised on a social platform. Instagram Shopping, TikTok Shop, and Pinterest’s buyable pins are all growing rapidly.

For UK retailers and product businesses, social commerce represents both an opportunity and a challenge. The opportunity is access to purchase intent at the point of discovery. The challenge is that the commission structures and data limitations of in-platform purchasing can reduce margins and visibility compared to direct website sales. Combining social commerce with AI marketing and automation allows businesses to personalise follow-up sequences and recover abandoned social shopping journeys more effectively.

The ROI of Video

Video marketing has delivered measurable commercial results for businesses. Research suggests 87% of marketers report increased sales from video, and platforms have consistently prioritised video content in their algorithms. Short-form video, particularly content under 60 seconds, generates the highest engagement rates of any content format.

Video does not need to be expensive to perform well. Authentic content filmed on a smartphone frequently outperforms polished production. What matters more than production quality is relevance and consistency. Our video production and marketing team works with businesses of all sizes to develop strategies that fit their resources and their audience’s expectations.

“The businesses we work with that see the strongest results from social media are the ones that treat it as a genuine communication channel rather than just a broadcast tool,” says Ciaran Connolly, founder of ProfileTree. “Consistent, useful content that actually helps your audience tends to outperform campaigns built purely around promotion.”

Brand Loyalty and Community

Ninety per cent of social media users follow at least one brand. The more meaningful metric for most businesses is not follower count but active community engagement: comments, shares, direct messages, and repeat visits to profile pages.

Content Trends Across the Social Media Industry

Content strategy within the social media industry has undergone a significant shift since 2020. The social media industry now demands a level of planning and consistency that simply did not exist five years ago. Platform algorithm changes, changing user behaviour, and the rise of AI-generated content have all contributed to a more complex landscape for brands and creators alike.

Short-Form Video Dominates

Forty-four per cent of users prefer to learn about new products through short-form video, making it the most effective content format for product discovery across all major platforms. TikTok established this expectation, and every major platform has since introduced short-form video formats in response.

For businesses new to video content, the practical starting point is answering common customer questions on camera. A 30 to 60 second video addressing a specific problem relevant to your audience will consistently outperform a two-minute brand overview in terms of reach and engagement. A structured content marketing plan ensures these videos sit within a broader editorial strategy rather than being produced in isolation.

Authenticity Over Polish

User-generated content and creator partnerships built on genuine recommendation have outperformed traditional brand-produced advertising. Audiences are sceptical of overly produced promotional content, while real customer reviews, behind-the-scenes footage, and honest product demonstrations earn higher trust scores. Brands that show the people behind the business tend to build stronger communities than those relying on polished campaigns.

Ephemeral and Interactive Content

Instagram Stories, Snapchat, and similar formats have become embedded in daily habits. The temporary nature of this content creates urgency; users act more quickly because the content will disappear. Polls and interactive stickers within Stories formats also give businesses a straightforward way to gather audience feedback.

The Rise of Social Search

An important shift within the social media industry is the use of platforms as search engines, particularly among younger users. Research from Adobe found that 40% of Gen Z users prefer TikTok or Instagram as their primary search tool over Google for certain queries, particularly around food, fashion, and local recommendations. For businesses focused on search visibility, this means social content should be written and filmed with search discovery in mind, not just social engagement metrics. A joined-up approach that connects your search engine optimisation strategy with your social content planning ensures both channels reinforce each other rather than operating in silos.

Social Media and Business: What the Data Means in Practice

These statistics matter most when they translate into commercial decisions.

Social Media as a Lead Generation Tool

Seventy-seven per cent of businesses use social media as a tool for reaching customers, but fewer have built clear pathways from social engagement to actual lead generation. The most effective approaches for generating enquiries through social channels combine consistent organic content with targeted paid campaigns, supported by landing pages designed to convert social traffic.

For service businesses in Northern Ireland and the UK, LinkedIn and Facebook tend to offer the clearest paths to lead generation, while Instagram and TikTok are more effective for brand awareness and product discovery. The right combination depends on who your customers are and how they make purchasing decisions.

Digital Training and AI in Social Strategy

The social media industry is increasingly shaped by artificial intelligence, both in how platforms distribute content and in how businesses create it. Platform algorithms are now sophisticated enough to predict individual user preferences with considerable accuracy, which has raised the bar for what content earns organic distribution.

AI tools are also changing how social media content is planned and produced. From AI-generated captions and image descriptions to automated scheduling and audience analysis, the practical toolkit for social media management has expanded significantly. AI chatbots are being deployed within social messaging channels to handle initial customer enquiries and qualify leads around the clock. ProfileTree delivers AI training for business owners and marketing teams through Future Business Academy, helping organisations understand how to use these tools without losing the authenticity that drives real engagement.

Negative Effects and Platform Risks

This sector also carries documented risks that businesses and individuals need to factor into their strategies. Research on the negative effects of social media includes evidence of impacts on mental health, particularly among young people, as well as risks related to misinformation, data privacy, and the amplification of harmful content. In the UK, the Online Safety Act has introduced legal obligations for platforms regarding harmful content, with direct implications for how businesses run paid campaigns and manage community interactions. Building compliance into your digital strategy from the outset is considerably less costly than retrospective adjustments.

Algorithm dependency is a separate but related risk. Organic reach has declined across most platforms as these networks have matured, meaning reliance on a single channel without an owned audience creates real commercial vulnerability.

Measuring What Matters

These platforms have collectively moved away from vanity metrics. Likes and follower counts are no longer the primary measure of commercial effectiveness. Shares, saves, comments, and website referral traffic are stronger indicators. For paid campaigns, cost per lead and conversion rate are the metrics that matter most.

Looking Ahead: The Social Media Industry in 2026 and Beyond

The social media industry is entering a phase defined by two competing forces: consolidation and fragmentation. For any business that depends on the social media industry for lead generation or brand awareness, this tension has direct practical consequences. A small number of large platforms continue to dominate advertising budgets, while users simultaneously migrate towards smaller, niche communities on Discord, WhatsApp Channels, and decentralised networks.

Broad reach and targeted community engagement are not mutually exclusive. The businesses that perform best will maintain a presence on the major platforms while also building direct relationships with their audiences through owned channels. Digital training for teams is increasingly how forward-thinking organisations ensure staff can operate confidently across both.

The social media industry will also continue to be shaped by regulatory change. The UK Online Safety Act, ongoing data privacy legislation, and advertising standards reviews all create compliance obligations that businesses need to factor into their social media planning. Working with an agency that understands both the commercial and regulatory dimensions of the social media industry reduces the risk of costly oversights.
