Highlights:

  • Tracks GA4 revenue (filtered for Google CPC) vs. Google Ads-reported revenue

  • Shows GA4-to-GAds revenue ratio over time

  • Highlights disparity percentage to benchmark attribution differences

  • Quickly detect if Google Ads is over-attributing performance

  • Aligns reporting between marketing and finance teams

  • Helps assess true incrementality of ad spend

  • Includes eCommerce summary for cost, GA4 ROAS, and GAds ROAS

  • Clear visual trend lines with day-level granularity

  • Explanatory notes clarify normal vs. concerning gaps

  • Actionable PoP and YoY variance indicators

The Attribution Disparity page helps you see through the fog of marketing attribution.

This report compares Google Ads-reported revenue with Google Analytics 4 revenue, specifically filtered for “google / cpc”.

The results are often striking: in many accounts, GA4 shows only one-third of what Google Ads claims.

That’s not necessarily a mistake — it’s just how attribution models differ.

Google Ads uses last non-direct click (and often inflates via data-driven attribution), while GA4 tends to be pessimistic, especially when using stricter first-party tracking setups.

The dashboard includes:

  • The GA4-to-GAds Revenue Ratio (in %)

  • The GA4 vs GAds Disparity (in % difference)

  • Visual trend graphs for both revenue sources

  • Commentary on normal thresholds and what deviations might mean

This is not just a reporting discrepancy—it’s a strategic signal. If GA4 attributes significantly less revenue to your ads, you should ask:

  • Are we cannibalizing organic or direct traffic?

  • Would these users convert without ads?

  • How much is truly incremental?

This module is especially useful for:

  • CMOs optimizing budgets

  • CFOs validating media spend

  • Marketers making a case for (or against) scaling


Use this report to defend budget decisions, uncover attribution inflation, and align internal teams on what “success” really means.
