Tags are a keyword or term that helps describe the product so that it can be found by browsing or searching. Unlike categories, tags have no hierarchy and allow for freeform organization.
Tags are used in the tag of the product page, so they have a marketing purpose behind them as well. The most popular tags are collected across your entire catalog to build the Tag Cloud widget.
￼Tags can also be used in your custom WordPress menus, and can be viewed as product collections on the storefront.
Enter tags into the entry field. You can enter multiple tags at one time by separating each tag with a comma (,), then click the Add button.
