Analytics: AI Traffic

Guides tracking of AI-driven search traffic in Google Analytics 4 and Google Search Console.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Scope

• AI search traffic: Track in GA4 and GSC; separate AI sources from organic referral
• Google AI Overviews: AI summary box in Google search (formerly SGE)
• AI-driven search: Traffic from ChatGPT, Perplexity, Gemini, Claude, Copilot, etc.

Why Track Separately

• AI traffic is growing but GA4 often groups it as Referral, Organic, or Direct
• AI visitors may have stronger intent and higher conversion
• Separating AI Overviews from organic helps assess AI impact

GA4: AI-Driven Search

Option 1: Exploration Report (Recommended)

1. Explore →Free form
2. Dimensions: Session source (or Session source / medium)
3. Metrics: Sessions, Engagement rate, Event count, etc.
4. Filters: Add filter →Session source Matches regex →use regex below
5. Configure table, save report

Regex (common AI sources):

chatgpt\.com|openai\.com|openai|perplexity\.ai|perplexity|doubao\.com|chat\.qwen\.ai|copilot\.microsoft\.com|copilot\.com|(business\.)?gemini\.google|chat\.deepseek\.com|deepseek\.com|poe\.com|anthropic\.com|claude\.ai|bard\.google\.com|edgeservices\.bing\.com

Option 2: Custom Channel Group

1. Admin →Data Display →Channel Groups
2. Copy default group, name e.g. “Default and AI Chatbots”
3. Add channel “AI Chatbots”: Source Matches regex (same regex)
4. Important: Place “AI Chatbots” above “Referral” so it matches first
5. Save and use in Traffic Acquisition

Option 3: Custom Report

1. Reports →Library →Create Detail Report
2. Use Traffic Acquisition template
3. Add filter: Session source Matches regex (same regex)
4. Save and add to menu
