Category

Categories can have parent and child terms, can appear in archive URLs and are commonly used for broad content organization. In practical terms, Category belongs to the publishing and site-management layer. Knowing that layer is important because it tells you what the term can change, what it cannot change, and where to look when something behaves unexpectedly.

The common mistake is to use Category as if it also meant Tag. That blurs two separate decisions and usually sends troubleshooting in the wrong direction. A better test is practical: Use categories for meaningful site structure rather than creating a new category for every minor keyword.

In day-to-day work, Category matters when the concept needs to be identified precisely instead of being grouped with a nearby term. The practical value is not the vocabulary itself; it is being able to identify the right control, file, setting or decision when the concept becomes relevant.

A news site might use categories such as Business, Design and Technology to create broad editorial groupings. That example is useful because it turns the definition into something you can recognize, test and discuss with other people working on the same project.

Use these references when you need documentation-level detail, specifications or product-specific behavior beyond the plain-English explanation above.
