GA4 SEO Configuration Audit

Audit a GA4 implementation to ensure organic traffic attribution, conversion tracking, and AI referral traffic measurement are accurate and actionable.

Context

Use this when onboarding a new SEO client or when analytics data doesn't match GSC observations. GA4 is the primary tool for understanding what organic and AI-referred visitors do after landing. Proper configuration ensures SEO work is measurable and attributable, and that AI referral traffic from ChatGPT, Perplexity, and Gemini is tracked separately.

Procedure

  1. Verify GA4 tag installation: correct property, all pages tagged, no duplicate tags.
  2. Audit channel groupings: confirm "Organic Search" captures all search engine traffic correctly.
  3. Configure AI referral tracking: add ChatGPT (chat.openai.com), Perplexity (perplexity.ai), Gemini (gemini.google.com), and Claude (claude.ai) as recognized referral sources in a custom channel group.
  4. Map conversion events: identify which GA4 events correspond to SEO-relevant business goals (form submissions, calls, purchases, sign-ups).
  5. Verify landing page reporting: ensure URL parameters are handled correctly and not creating false page variations.
  6. Check consent mode and data collection settings for privacy compliance.
  7. Build or recommend a reporting dashboard for organic + AI traffic with conversion attribution.

QA Rubric (scored)

  • Installation accuracy (0-5): tag verified on all pages, no duplicates, correct property.
  • AI tracking coverage (0-5): all major AI referral sources configured and grouped.
  • Conversion mapping (0-5): events match real business goals and are firing correctly.
  • Reporting utility (0-5): dashboard template provides actionable organic and AI traffic insights.

Examples (good/bad)

  • Good: "AI referral traffic from chat.openai.com currently grouped under 'Referral' along with 200 other sources. Fix: create custom 'AI Referral' channel group capturing ChatGPT, Perplexity, Gemini, and Claude domains. This separates AI-driven visits for GEO reporting."
  • Bad: "Set up Google Analytics on your site." (no audit, no specific configuration, no AI tracking)

Variants

  • Setup variant: fresh GA4 configuration for a new site with SEO and GEO tracking from day one.
  • Audit variant: review existing GA4 implementation, fix issues, and add AI referral tracking.
