Meta says 1,610 sales. GA4 says 812. Your store says 1,240.
Which one is lying? 🤔 Usually... all of them.
Here's what I find in almost every tracking audit 👇
❌ Purchase event firing twice (thank-you page reloads)
❌ Pixel + CAPI running without event_id, so Meta double-counts
❌ GA4 losing sales to ad blockers and Safari ITP
❌ Consent Mode v2 blocking tags instead of modeling
The fix isn't another plugin. It's this 👇
✅ One clean dataLayer as the single source of truth
✅ Deduplicated browser + server events
✅ Server-side GTM on a first-party subdomain
Result? Your ad platforms match your real orders, and the algorithms optimize on real data instead of guesses.
