What is the difference between WordPress Categories and Tags?

WordPress categories play a crucial role, serving as a comprehensive guide that assists users in understanding the content of a blog better. While a post can belong to multiple categories, it’s required that each post be associated with at least one category.

In contrast, WordPress tags, though similar to categories, are employed for a more detailed description of a post. Unlike categories, the inclusion of tags in a post isn’t mandatory. However, should the need arise, a single post can feature multiple tags for a more nuanced understanding.
