Saneo France Meta Pixel Tracking Recovery: conversions started counting again

Saneo France, a health product e-commerce website, faced restricted Meta Pixel tracking due to HIPAA compliance issues. Over a multi-week engagement, we implemented server-side tracking via Custom Server, configured Meta Conversion API, and added Shopify webhooks to achieve 98.74% tracking accuracy, recovering 23.72% of events from ITP and 3.85% from ad blockers, while improving ROAS to 1.03.

“I can't say enough good things about Shahzada. Some of the nuances of our project were over my head, but he understood them completely and executed everything smoothly and quickly. Would 10000% recommend working with Shahzada.”
