Attribution
AnalyticsDefinition
Attribution is the process of assigning credit for a conversion to the marketing touchpoints that influenced it. It determines which channels, campaigns, and interactions deserve credit for driving a sale, lead, or other goal.
Attribution is one of the hardest problems in digital marketing. A customer may see a Meta ad, click a Google Search ad, open an email, and then convert through a direct visit. Different attribution models give different answers, and none is perfectly accurate.
GA4 uses data-driven attribution by default. Google Ads uses its own data-driven model. Meta uses its own click and view windows. These platform-level models inevitably give more credit to themselves.
Set up conversion tracking across all platforms. Choose an attribution model in GA4 (data-driven recommended). Compare platform-reported conversions against GA4 and CRM data. Use incrementality testing (holdout experiments) to validate true channel contribution.
Without proper attribution, you allocate budget based on misleading data. Last-click overvalues bottom-funnel channels; platform-reported attribution overvalues each platform. Understanding true attribution prevents cutting upper-funnel channels that drive pipeline.
