ChatGPT Dominates AI Referral Traffic with 92.4% Share, Study Reveals

A recent study by Previsible, analyzing 6.77 million LLM-driven sessions, indicates that ChatGPT accounts for a staggering 92.4% of all trackable AI referral traffic. This data, covering November 2024 through May 2026, highlights a significant consolidation in the AI referral landscape, with monthly LLM sessions growing 9.9 times over the period. For businesses and marketers in India focusing on digital presence and AI-driven strategies, this dominance underscores the critical importance of optimizing for ChatGPT visibility.

The study provides a detailed look at the evolving dynamics of AI referrals, revealing not only ChatGPT’s lead but also the surprising rise of Claude and the decline of platforms like Perplexity and Copilot in terms of traffic generation. This shift demands a re-evaluation of how companies approach their AI visibility and content distribution strategies.

Market Consolidation and Growth

The past 19 months have seen dramatic changes in AI referral patterns. While overall LLM sessions have surged, reaching 644,478 in May 2026, the market has largely converged around a single leader. ChatGPT’s share has grown to 92.4%, an increase from approximately 84% just six months prior in December 2025. This indicates that while many platforms initially competed for discovery, only ChatGPT has managed to sustain and significantly grow its referral volume at scale. The data also shows significant volatility, with sudden drops in traffic, as experienced in November 2025, often linked to product tweaks by the dominant AI models.

Key facts:

• ChatGPT’s market share: 92.4% of LLM referral traffic
• Total sessions analyzed: 6.77 million
• Monthly LLM session growth: 9.9x (November 2024 to May 2026)
• Claude’s growth: 64x increase in sessions

The Rise of Claude

Beneath ChatGPT’s overarching dominance, the study points to Claude as a significant mover. Claude’s referral traffic grew 64-fold, from 133 sessions in November 2024 to 8,528 in May 2026. It surpassed Perplexity in March 2026 and has maintained its lead. This acceleration is attributed to the adoption of its agentic tools and enterprise integrations. For Indian enterprises, developers, and technical buyers, this signals that Claude is becoming a material platform for visibility, opening a window for early positioning and content optimization.

Challenges for Other Platforms

While Gemini has shown quiet but steady growth, increasing 3.2 times, its actual discovery footprint is likely undercounted due to its deep integration with Google Workspace and Android. In contrast, Perplexity and Copilot, once considered strong contenders, have seen substantial declines in referral traffic. Perplexity’s monthly sessions dropped by 61% from its peak in March 2025, and Copilot experienced a 96% collapse from its August 2025 peak. The study suggests these platforms are shifting towards retaining users within their own ecosystems rather than driving external traffic.

The Internal Search Conundrum

Perhaps the most actionable insight for digital marketers and SEO professionals is the role of internal search pages. The study found that 28.8% of ChatGPT’s referrals, and roughly 25% of all AI-referred traffic across industries, land on internal search results pages. This indicates that while AI models are adept at identifying relevant domains, they often struggle to pinpoint the exact landing page. Consequently, users are directed to a site’s internal search, leaving the conversion-or-bounce decision to the quality of the internal search user experience. For Indian businesses, this highlights an often-neglected area that can significantly impact the effectiveness of AI-driven traffic. Optimizing internal search functionality becomes as crucial as optimizing for external visibility.

Implications for Indian Digital Marketing and SEO

For digital marketers and SEO specialists in India, these findings are critical. ChatGPT’s overwhelming share means that any strategy aimed at “AI visibility” must prioritize optimization for this platform. Furthermore, the volatility observed in referral traffic due to model changes emphasizes the need for continuous monitoring and agile adaptation of SEO strategies. The rise of Claude, particularly for technical audiences, suggests new avenues for targeted content and engagement. Crucially, improving internal search functionality is no longer a mere UX enhancement but a direct acquisition lever to convert high-intent AI-referred visitors.
