Mixing UK, EU and US sizesSet a size system and stick to it.

Gender and age group left blankGoogle requires them for clothing. Fill them in.

Fashion taxonomy FAQs

What is product taxonomy in fashion ecommerce?

The way you group and describe products: departments, categories, product types and attributes like size, colour and fabric.

Why does taxonomy matter for fashion stores?

Fashion has huge choice and lots of variants. A clean taxonomy powers filters, Google Shopping and AI recommendations, so shoppers find the right item fast.

Which attributes does Google need for clothing?

For clothing, Google expects colour, size, gender and age group, plus an item group ID for variants. Material and pattern help too.

Should I use Shopify's taxonomy or build my own?

Both. Use Shopify's standard category for every product, then add your own product types and tags for collections and menus.

How does taxonomy help with AI search in 2026?

AI tools match questions like "breathable linen shirt" to product data. Complete attributes make you easier to recommend.

How often should I review my taxonomy?

Check it every season, or whenever you launch a new range or category.
