Track AI-driven search traffic

Track AI-driven search traffic separately

Growth marketers trying to understand the new AI-driven referral channel and separate it from traditional organic/referral attribution.

• · GA4 Session Source dimension data
• · GSC query data with AI search sources

• · AI traffic Exploration report in GA4
• · Custom channel group separating AI from referral
• · Traffic metrics for ChatGPT, Perplexity, Copilot, Gemini, Claude sources

• · GA4 (Exploration reports, custom channel groups)
• · Google Search Console optional (for AI Overviews filtering)

• · GA4 configured with Session Source dimension
• · AI traffic already arriving (baseline not zero)

• · AI sources may be grouped as Referral or Organic in GA4 defaults; manual config required
• · New AI sources emerge; regex must be updated periodically (ChatGPT variants, emerging LLM chat UIs)
• · AI Overview clicks in GSC hard to isolate; URL fragment tracking incomplete
• · Small traffic volumes may not reach statistical significance for action

• · Three implementation options: Exploration (recommended), Custom Channel Group, Custom Report
• · Regex for common AI sources (ChatGPT, Perplexity, Copilot, Gemini, Claude, etc.)
• · Table of common AI source domains by platform
• · Channel group placement guidance (AI above Referral so it matches first)
• · Related skill references (GEO, traffic-analysis, google-search-console)
