What we check

Red flag

GA4 ↔ Shopify gap

5–10% is normal. Over 20% usually means a configuration bug quietly losing data.

Watch

Pixel + CAPI dedup

Double-counted purchases inflate your ROAS and mislead ad platforms — the most common cause.

Healthy

Event Match Quality

6 is Meta's own floor; 8+ is the working target for Purchase. Email-only setups typically stall at 4–6 and leave attribution on the table.

How you fix it

1
Diagnose
You reconcile a closed week across Shopify, GA4 and Meta to see exactly where your numbers break.
2
Fix
You deduplicate your pixel and CAPI, repair the purchase event, raise match quality and move server-side — step by step in the guides.
3
Verify
You prove it with a test order — DebugView, Test Events and a fresh reconciliation, not a green checkmark.

Why you can trust these numbers

Evidence-based

Every benchmark comes from primary Google, Meta and Shopify documentation and specialist practitioners — and we cite the sources on every guide.

Diagnostic-first

Shopify's server-side record is your source of truth; everything reconciles against it. No inflated claims, no invented case studies.

Independent

No affiliate commissions from the tools we compare. When we recommend a vendor, it's because it fits — not because it pays.
