From 40% signal loss to 99.9% tracking accuracy in 2 weeks.

The challenge

NatureDrip was running aggressive Meta campaigns but iOS 17 had decimated their pixel signal. Reported ROAS was 2.1× but actual revenue didn't match. Their team had no visibility into what was working.

What we did

• Full tracking audit revealing 40% event loss on Purchase and AddToCart events
• Meta CAPI implementation with server-side Purchase event firing
• Pixel and CAPI deduplication via event_id matching
• GA4 server-side setup via GTM server container
• Real-time monitoring dashboard with EMQ alerts

Results

• Event Match Quality jumped from 4.2 to 9.1 within 72 hours of CAPI launch
• Reported ROAS increased from 2.1× to 4.2× — actual revenue unchanged, data was the problem
• Meta campaigns could now optimize on clean Purchase signals, CAC dropped 22%
• GA4 data now matches Shopify revenue within 2% margin
