--- title: "Facets" weight: 1 --- # Facets Facets are the primary means to attach structured data to your Products & ProductVariants. Typical uses of Facets include: * Enabling faceted search & filtering in the storefront * Organizing Products into Collections * Labelling Products for inclusion in Promotions {{< figure src="../screen-facet-list.webp" >}} A Facet has one or more FacetValues, for example: * Facet: "Brand" * Values: "Apple", "Logitech", "Sony", "LG" ... ## Assigning to Products & Variants In the Product detail page, you can assign FacetValues by clicking the _ADD FACETS_ button toward the bottom of the Product or ProductVariant views. {{< figure src="../screen-facet-add.webp" >}} ## Public vs Private Facets The visibility of a Facet can be set to either _public_ or _private_. * **Public** facets are visible via the Shop API, meaning they can be listed in the storefront and used for faceted searches. * **Private** facets are only visible to Administrators, and cannot be used in storefront faceted searches. Private facets can be useful for labelling Products for internal use. For example, you could create a "profit margin" Facet with "high" and "low" values. You wouldn't want to display these in the storefront, but you may want to use them e.g. in Promotion logic.
