WordPress: The difference Between Categories and Tags
I wanted to clear up the difference between categories and tags in WordPress, something I find myself explaining very often to clients new to the WordPress publshing platform. WordPress Categories are your table of contents. WordPress Tags are your index words, think of a book metaphor;
WordPress categories are your table of contents, at the front of a book there’s a “Contents” which showcases the main chapters of content for the book. The Categories are the hierarchy of your content.
A blog post normally has one category, though it may fit in one or two categories, or even in sub categories.
Tags are your index words, at the back of a book is an “Index”, a listing of words which you can find specific information. Just like your index in a book your WordPress tags are a link, but, a hyperlink to related information.
A blog post normally has two or three descriptive tags.
