AI Referral Traffic Intelligence in North America - 07/14/2025
We believe in optimizing for the retrieval layer. But we got curious about who's actually sending the most clicks and how often that shifts.
So we're tracking it. Following the data wherever it leads us. We're not entirely sure what we've built or where it's headed. But here's what we're seeing so far:
AI platforms are already sending traffic to your website. We track this referral behavior to help businesses try to understand where their undefined traffic might be coming from and which platforms seem to be driving the most outbound clicks.
Unlike usage or adoption metrics, our data measures click-out behavior, when users actually leave AI platforms to visit external websites. This reveals patterns that suggest commercial intent and helps businesses think about how to prioritize their AI optimization efforts.
Updated weekly with North American data and full source transparency.

ChatGPT Analysis
Maintains overwhelming dominance with 79.1% AI referral traffic share. Strong across all platforms: #2 on iOS, #1 on Android, with 485M monthly users and 34% penetration among US adults. The clear referral traffic leader across every measured metric.
Microsoft Copilot Analysis
Solid #2 position with 10.77% referral traffic share, driven by enterprise integration. Notable absence from mobile app rankings suggests usage primarily through Microsoft 365 ecosystem. Developer AI tool usage remains strong across enterprise environments.
Perplexity Analysis
Claims 5.5% referral traffic share but limited presence in other metrics. Positioning as AI-powered search engine creates distinct niche, though mobile app presence remains minimal. Growth dependent on search-focused use cases and differentiation.
Google Gemini Analysis
Despite low 2.74% referral traffic share, claims impressive 400M monthly users through Google app integration. Mobile presence via Google app (#5 iOS) suggests significant usage not captured in referral metrics. Integration strategy creates hidden scale.
Google Gemini's low referral traffic (2.74%) despite 400M users likely reflects Google's ecosystem integration strategy.
Unlike standalone AI platforms, Gemini users can seamlessly transition to traditional Google Search within the same session, making those clicks appear as Google Search referrals rather than Gemini referrals. Additionally, Gemini's integration with Google's AI Overviews feature is designed to provide comprehensive answers that reduce the need for external clicks.
Claude Analysis
Smallest referral traffic share at 1.89% but strong reputation for quality responses. Social sentiment shows preference for writing and detailed analysis tasks. Limited mobile presence suggests primarily desktop/web-based professional usage patterns.
