ChatGPT dominates LLM traffic—by far. But traffic from smaller models is starting to add up too.

Essential Statistics

• ChatGPT drives an average of 43.4 visitors per site per month.
• Gemini sends 1.5 visitors/month.
• Copilot drives 1.3/month, Perplexity 0.9, and Claude 0.5.
• ChatGPT accounts for 90%+ of current LLM traffic.
• The rest of the field is small—but not negligible.
• Sites optimizing for multiple LLMs are seeing incremental gains.
• Traffic is likely underreported due to attribution lag.

Key Takeaways

• ChatGPT is the clear leader in AI-generated traffic.
• Other LLMs are emerging but still have low volume.
• Early adopters of multi-LLM strategies are stacking small wins.
• Most marketers are still underestimating AI-origin traffic.
• AI SEO isn’t just theory—it’s measurable now.
• Attribution may miss the full impact of these visits.
• Even sub-1% traffic adds up over scale.

Actionable Insights

• Start optimizing for LLM discoverability. Use structured content, summaries, and schema to be AI-readable.
• Don’t just focus on ChatGPT—smaller LLMs will grow faster than expected.
• Track LLM-origin traffic in analytics, even if it’s small at first.
• Use early LLM traffic as a signal—optimize what’s already working.
• Repurpose existing high-performing pages for AI-friendly formatting.
• Be proactive—waiting to adopt AI SEO means missing easy early wins.
• Build attribution dashboards that capture LLM referral influence.
