Tags in Joomla are keywords or labels you can assign to any piece of content — articles, contacts, news feeds, and more — to group related items together regardless of where they sit in your site's category structure. Unlike categories, which organize content in a strict hierarchy, tags offer a flexible, cross-cutting way to connect content around topics or themes.

11.1 Content Tags — Create a tag, apply it to articles, then use tags to display related articles.

Thoughtful use of tags can help content managers keep sites organized and help visitors discover related content naturally.
