What is a Tag?
A Tag is one of the pre-defined metadata classifications in WordPress. Blog article creators can add tags to their WordPress posts in coordination with categories and menus to organize and provide internal site search capabilities.
In many ways meta tags are like categories, they both help visitors and search engines to find the content they are looking for. But where categories divide your articles into hierarchical groups, meta tags have no hierarchy. They describe your content on a micro level, where categories describe it on a macro level.
Tags:
- Are not keywords
- Are narrower in scope and more focused on specific blog article topics than Categories
- Are nonhierarchical
- Are ‘Focus Words’ or ‘Topic Words’ used to identify blog article topics
- Are also used by certain WordPress themes and widgets to provide the ‘Posted In’ topic list and ‘Word Cloud’
- Are not automatically added to a blog article unlessa user adds them
