Your Meta Ads report says 340 sales. Your store says 190. Your product isn't broken—your pixel is.
Why Does My Facebook Pixel Show Duplicate Conversions?
Your Browser Pixel and Server-Side CAPI are both firing for the same purchase—with no shared event_id to tell Meta it's one event, not two.
Super common if you're running WooCommerce or a custom checkout.
What it was doing: 📉 Reported conversions way above real orders 📉 CPA looked artificially low 📉 Ad budget kept shifting toward the "wrong" campaigns
How it got fixed: 🔧 Set a matching unique event_id on both Pixel and Conversions API calls 🔧 Verified deduplication in Events Manager → Test Events 🔧 Cross-checked GA4 numbers against Ads Manager
Result: [X]% drop in duplicate events, and CPA numbers you can actually plan a budget around.
No ad spend decision is better than the data it's built on.
Does your reported conversion count match your real order count? If not, this is usually why.
