Metafields
Custom fields on products, collections, customers and orders — the way you extend Shopify’s data model.
WHY IT MATTERS
Why it matters for a Shopify store.
Out of the box, a Shopify product has a title, description, price and a few standard fields. Metafields add the rest — materials, care instructions, specs, size charts — as structured data.
Structured data can be filtered, shown in the right place on the page and reused in schema markup, instead of living in one long description.
HOW CREATIVE LABS HANDLES IT
What we do about it on every project.
01
Define, don't improvise
Metafield definitions with types and validation, so data stays consistent.
02
Connect to the theme
Dynamic sources show metafields in sections without code changes.
EXAMPLE
A typical example.
A footwear brand keeps materials and fit notes inside each product description.
They move into metafields, appear as consistent spec rows on every product page and power a filter by material on collection pages.
COMMON MISTAKES
What usually goes wrong.
Untyped metafields
Without definitions, data drifts and can't power filters.
Everything in the description
Long descriptions hide facts shoppers and search engines need.
Too many one-off fields
Plan the model; dozens of rarely used fields confuse editors.
METAFIELDS
2 questions
What's the difference between metafields and metaobjects?
Metafields add fields to existing objects like products; metaobjects are new content types with their own entries.
Can metafields be used in filters?
Yes. Shopify's Search & Discovery app can filter collections by many metafield types.
