Use clean, controlled taxonomy from Emfas for your reporting in Google Analytics so that they are always accurate and don't become unreliable over time due to category names drifting over time.

Littledata rewrites the item_category parameter using the normalized category metafield from Emfas, replacing Shopify's free-text product type before the event reaches GA4.

Because item_category is a built-in GA4 dimension, your category breakdown works immediately in standard reports and explorations. There is no custom dimension registration and schema change.
Emfas syncs normalized product category data to Shopify as metafields, and Littledata can turn it into a clean analytics signal for your events.
