Why it works
The core before-state is not knowing: GA4 was hiding up to 60% of conversions from users who declined cookies, so Movember was making budget decisions on a structurally incomplete picture. The 'fascinating discovery' section earns its place because it reframes the gap not as a technical nuisance but as a strategic distortion of campaign performance in the charity's most important markets. The explicit numeric comparisons between GA4 and Mixpanel capture rates give the Clarity story concrete teeth that most visibility-shift case studies lack.
Steal this
The side-by-side capture-rate comparison (GA4 vs. Mixpanel vs. backend ground truth) gives the reader an unambiguous before/after that is impossible to dismiss as vendor spin. Anchoring data quality claims to an independent backend system rather than to Mixpanel's own numbers is the structural move worth copying.
