Q. What is the function of Categories and Tags within WordPress and how have you utilised these?
Both categories and tags are known as taxonomies (a scheme of classification – dictionary.com), they exist to sort your content into groups and therefore improve the usability of your site. Users can easily browse through your content by topic, finding the correct content by viewing the listed categories and tags. A users experience can be vastly improved by these well-constructed navigational elements (categories and tags).
