AI-driven web referrals soar 357% in June 2025, boosting digital dynamics

The rapid ascent of artificial intelligence platforms as drivers of digital traffic in 2025 marks a pivotal shift in how online ecosystems function. Recent data indicates that in Q2 2025 (April to June), AI platforms directed over 1.13 billion referrals to the top 1,000 websites globally, reflecting a staggering growth of 357% compared to the same period in 2024. This statistic, highlighted in discussions on platforms like X through accounts such as StockMKTNewz, underscores the growing influence of AI tools in shaping user behaviour and publisher fortunes. Yet, beneath this headline figure lies a more nuanced story of uneven benefits, competitive dynamics, and the persistent challenge of ‘zero-click’ search trends.

Breaking Down the Referral Boom

The surge in referrals from AI platforms, primarily conversational tools like ChatGPT and Microsoft Copilot, represents a significant departure from traditional search engine dynamics. According to SimilarWeb’s latest analysis for Q2 2025, ChatGPT alone accounts for nearly 79.1% of AI-driven referral traffic in North America, with Microsoft Copilot contributing around 10.8%. This concentration suggests that a handful of dominant players are steering the bulk of this new traffic source. Globally, the 1.13 billion referrals in June 2025 to leading websites—encompassing news, finance, and sports content—signal that AI tools are increasingly acting as gatekeepers to information.

However, the raw numbers must be contextualised. While the year-on-year growth is impressive, AI referrals still constitute a small fraction of total web traffic for most publishers. Data from TechCrunch, drawing on SimilarWeb insights for Q2 2025, shows that even top beneficiaries like Reuters (up 8.9% in referral traffic year-on-year) and Business Insider (up 6.5%) are not seeing these gains offset declines in organic search traffic. Google’s AI Overviews, rolled out in mid-2024, have exacerbated this by increasing ‘zero-click’ searches—where users receive answers directly on the search page—from 56% to 69% of total queries by May 2025.

Who Benefits and Who Loses?

The distribution of AI referral traffic is far from equitable. A closer look at Q2 2025 data reveals that websites covering finance, stocks, and sports dominate the recipient pool, as these topics align with the query patterns of AI platform users. For instance, publishers like the New York Post saw a 7.1% year-on-year uptick in ChatGPT referrals. In contrast, other major outlets, particularly those engaged in legal disputes over content usage with AI firms, have seen more modest gains. This disparity hints at algorithmic biases or prioritisation within AI models that publishers must navigate.

The table below illustrates the uneven spread of referral traffic growth among select top publishers for Q2 2025:

These figures, sourced from SimilarWeb via TechCrunch, highlight that while growth exists, it is neither universal nor sufficient to counterbalance broader traffic losses from search engine shifts.

The Bigger Picture: AI as Friend or Foe?

For all the buzz around AI-driven referrals, the technology’s broader impact on digital publishers remains a double-edged sword. The rise of ‘Google Zero’—a term capturing the fear of near-total traffic loss due to AI summaries—looms large. As reported by eWeek in July 2025, Google’s AI summaries are directly linked to sharp declines in website clicks, pushing publishers to rethink revenue models. If AI platforms can answer queries without directing users to external sites, the very notion of referral traffic could become obsolete for many.

On the flip side, the competitive landscape among AI platforms offers some hope. Microsoft’s Bing, bolstered by AI integration, recorded over 1.4 billion visits in May 2025, capturing roughly 4% of global search referrals. This growth, as noted in DataReportal’s July 2025 Statshot, suggests that alternative engines might dilute Google’s dominance over time, potentially redistributing traffic in unforeseen ways.

Looking Ahead: A Balancing Act

The trajectory of AI-driven referrals in 2025 will hinge on several factors: the evolution of user trust in AI responses, the willingness of platforms to prioritise external links over internal summaries, and the adaptability of publishers to this new reality. While 1.13 billion referrals in June 2025 is a figure worth noting, it is not a panacea. Publishers must diversify traffic sources and explore direct engagement models, lest they become overly reliant on the whims of AI algorithms.

In a landscape where technology both giveth and taketh away, a touch of irony emerges: AI platforms, heralded as the future of information access, might just render the very websites they refer to as relics of a bygone era. For now, the numbers tell a story of growth—but one that demands cautious interpretation.
