Reddit Overtakes TikTok as UK’s Fourth Largest Social Platform

Platform's 88% growth in UK reach, combined with Google algorithm changes and AI deals, creates significant opportunities for performance marketers

Reddit has overtaken TikTok to become Britain's fourth most visited social media platform, according to new data from Ofcom. The shift represents a fundamental change in how UK consumers discover products and seek recommendations, with major implications for affiliate marketing strategy.

The platform has experienced 88% growth in UK reach over the past two years. Three in five British internet users now encounter Reddit, up from just one third in 2023. For affiliate marketers who have been treating Reddit as a secondary channel, these numbers demand a strategic reassessment.

The Numbers Behind the Surge

Reddit's growth is particularly pronounced among younger demographics. The platform now ranks as the sixth most visited site of any kind by UK users aged 18 to 24, up from tenth place a year earlier. More than three quarters of that age group now visit the platform regularly.

The UK represents Reddit's second largest market globally, trailing only the United States. This concentration of engaged users in a major affiliate market creates opportunities that did not exist even 18 months ago.

Several factors have driven this expansion, but changes to Google's search algorithms appear to be the primary catalyst. Google's pivot toward prioritising “helpful content” from discussion forums has sent significantly more traffic to Reddit's community discussions. For affiliates who understand how Google's outsourcing of long-tail search to Reddit affects their strategies, this shift creates clear tactical opportunities.

Reddit's deals with both Google and OpenAI have amplified this effect. The platform is now the most frequently cited source in Google's AI Overviews, meaning Reddit discussions increasingly appear at the top of search results for product research queries. A similar arrangement with OpenAI ensures Reddit content surfaces in ChatGPT responses.

A Platform Transformed

The Reddit of 2026 bears little resemblance to its reputation from even a few years ago. The platform was long perceived as hostile territory dominated by anonymous users in male-oriented technology and gaming communities. That characterisation is now outdated.

More than half of Reddit's UK users are women. Internal company research indicates that 71% of women on the platform in the UK have a personal interest in skincare, beauty and cosmetics. These are precisely the product categories where affiliate marketing thrives.

“Reddit has become very diverse,” said Jen Wong, Reddit's Chief Operating Officer, in a recent interview. “It is gender-balanced in the UK now. What's interesting is that one in three are Gen Z women on the platform.”

This demographic shift opens affiliate opportunities in verticals that are rewriting industry economics. Health, wellness and beauty categories that command premium commissions now have substantial, engaged audiences on a platform where authentic recommendations carry significant weight.

Why Younger Users Are Choosing Reddit

Wong pointed to a specific behavioural pattern driving growth: younger users actively seeking human-generated opinions rather than algorithmically curated content or AI-generated summaries.

“Gen Z are very open to looking online for advice around these life stage moments, like leaving home and renting for the first time,” Wong explained. “It's a very safe place to ask questions about balancing a cheque book, or how to pay for a wedding.”

This insight aligns with broader trends around user-generated content becoming central to digital marketing. When consumers actively seek out authentic human perspectives, affiliate marketers who can provide genuine value within community discussions gain a significant advantage over those relying purely on paid placement.

UK subreddits focused on pregnancy and parenting have doubled in size over the past year. The Premier League subreddit has grown by more than a billion views annually. Women's football communities covering Arsenal's women's team and the Lionesses have seen viewership double.

These growth patterns indicate that Reddit is capturing attention during high-intent research moments, exactly when affiliate recommendations convert best.

The “Anti-AI” Positioning

Wong's comments on AI-generated content are particularly relevant for affiliate marketers navigating the current landscape. She positioned Reddit explicitly as an antidote to the AI content flooding other platforms.

This positioning matters because it suggests Reddit will continue attracting users specifically seeking authentic human perspectives. In a separate interview with EMARKETER, Wong expanded on this theme: “What Reddit has is this humanness and connection,” she said, contrasting it with the increasingly synthetic web. “In an AI-dominated media environment, Reddit's real voices, opinions, and communities may only grow more valuable.“

For affiliates, this creates an environment where genuine expertise and honest recommendations can outperform polished but impersonal content.

The emphasis on authenticity also explains why Reddit requires a fundamentally different marketing approach than other social platforms. Users who arrive specifically seeking real opinions will reject obvious promotional content more aggressively than audiences on platforms where advertising is expected.

Strategic Implications for Affiliate Marketers

Reddit's rise creates both opportunities and challenges for performance marketers. The platform's unique culture demands approaches that differ significantly from standard social media tactics.

Community participation becomes essential. Reddit's structure means affiliates cannot simply broadcast promotional content. Success requires genuine engagement within relevant subreddits, building credibility over time before any commercial activity.

Organic reach gains importance. Recent changes to Reddit's ad settings that allow premium users to hide all advertising mean organic content and community credibility matter more than paid placement. Affiliates who build genuine authority within communities will maintain reach even as paid options become less effective.

New advertising tools lower barriers. For those who do want to invest in paid promotion, Reddit's new advertising infrastructure now allows direct import of campaigns from Meta platforms. Nielsen research indicates Reddit ads deliver £1.97 return on ad spend for retail advertisers, outperforming many competing channels.

Community intelligence provides research value. Reddit's recently launched Community Intelligence platform offers tools for understanding genuine consumer discussions about products and services. Even affiliates not actively marketing on Reddit can use these insights to inform content strategy across all channels.

The Broader Platform Landscape

Reddit's growth should be viewed within the context of shifting social media dynamics affecting affiliate marketing. While overall social media usage has declined, with consumers spending 11% less time on platforms, Reddit has grown against this trend.

This suggests Reddit is capturing attention that previously went elsewhere, rather than simply benefiting from overall social media growth. For affiliates evaluating platform investment, Reddit's counter-trend growth indicates genuine user preference rather than temporary algorithmic favour.

The platform's emphasis on community as a core value also aligns with broader shifts in how affiliate marketing works. Transactional approaches are giving way to relationship-based strategies, and Reddit's structure naturally rewards those who invest in genuine community participation.

Practical Next Steps

For affiliate marketers considering Reddit as a strategic channel, several actions make sense given this data:

Audit relevant subreddits. Identify communities where your target audience discusses products in your niche. Observe the culture, understand what content gets upvoted, and note which types of recommendations gain traction.

Start building presence now. Reddit rewards account age and karma. Beginning authentic participation today positions you for commercial opportunities months from now. Waiting until you need the channel means starting from zero credibility.

Consider the UK specifically. With the UK as Reddit's second largest market and the platform's fastest growth occurring there, UK-focused affiliate programmes may find particularly strong opportunities. The gender balance and demographic shifts mean categories previously underrepresented on Reddit now have substantial audiences.

Monitor Google integration. Reddit's position as the most cited source in AI Overviews means optimising for Reddit visibility has downstream SEO benefits. Content that performs well on Reddit increasingly appears in search results, creating compound returns on community investment.

Reddit's rise past TikTok in the UK market is not a temporary fluctuation. The platform's integration with Google search, its positioning against AI-generated content, and its demographic transformation all suggest sustained relevance for affiliate marketers willing to adapt their approach.

The affiliates who invested in Reddit community building over the past two years are now positioned to capture significant value. Those starting now face more competition but enter a larger, more diverse market than existed previously.
