GLOSSARY · P
Pixels
Shopify’s sandboxed way of running tracking scripts for Meta, Google and others.
WHY IT MATTERS
Why it matters for a Shopify store.
Marketing platforms need conversion data, but tracking scripts slow pages and break checkout. Shopify's pixels run tracking code in a sandbox and receive standard customer events.
With Checkout Extensibility, pixels replace scripts that were added to checkout's additional scripts box, so tracking setup changes during the upgrade.
HOW CREATIVE LABS HANDLES IT
What we do about it on every project.
01
Use app pixels where possible
Official apps from ad platforms subscribe to events with no custom code.
02
Write custom pixels carefully
Custom pixels map Shopify's customer events to the platform's needs and are tested end to end.
EXAMPLE
A typical example.
A Plus store upgrades to Checkout Extensibility and its old purchase tracking script stops firing.
Conversion tracking moves to app pixels and a custom pixel for one platform, and purchases are compared before and after to confirm nothing is missing.
COMMON MISTAKES
What usually goes wrong.
Duplicate tracking
An app pixel plus old theme code double-counts conversions.
Not testing consent
Pixels respect customer privacy settings; check events with consent given and refused.
Forgetting the thank-you page
Old order status scripts must be moved to pixels or extensions.

What's the difference between app pixels and custom pixels?
App pixels are installed by apps such as ad platforms; custom pixels are code you add in Settings → Customer events.
Do pixels work on checkout?
Yes. Pixels receive checkout events, which is why they replace checkout scripts.
