AI Traffic Attribution

Determining which AI engine, citation, or summary drove a given visit.

Hard, because referrer headers don't always survive AI surfaces. Some AI engines pass referrers cleanly; others strip them. Attribution requires a combination of UTM tagging in cited URLs (where you control them), bot-log correlation, and panel-based survey data.

Use cases
  • AI Channel Performance MeasurementTracking visits, engagement, and conversions from different AI sources (ChatGPT vs Perplexity vs Bing Copilot) to understand which AI platforms drive the most valuable traffic.
  • GEO ROI CalculationMeasuring traffic and conversion impact of GEO initiatives by accurately attributing AI-influenced visits, enabling proper return on investment analysis for AI optimization efforts.
  • Customer Journey MappingUnderstanding how AI touchpoints fit into multi-channel customer journeys, identifying patterns where AI discovery leads to conversion through various paths.
  • Content Performance AnalysisIdentifying which content pieces drive the most AI-attributed traffic, revealing what types of content AI systems prefer to cite and link to.
  • Competitive IntelligenceComparing AI traffic share against industry benchmarks and competitors to understand relative AI visibility and market positioning.
  • Marketing Attribution ModelingIncorporating AI touchpoints into multi-touch attribution models to properly credit AI's role in conversion paths alongside traditional channels.
