WordPress Dashboard > Posts > Tags
Tags are a flexible way to group related posts together. Unlike categories, tags do not have a hierarchy.

Add New Tag
Name The name as it will appear on your site.
Slug The URL-friendly version of the tag name. Usually lowercase and includes only letters, numbers, and hyphens. Example:
summer-recipesDescription An optional field. Some themes may display the description, though it’s not shown by default.
Tags List
Displays all tags in a sortable table.
Columns include:
Name
Description
Slug
Post Count (number of posts assigned to the tag)
Use the checkboxes and Bulk Action dropdown to:
Delete tags
Edit multiple tags
Note: No tags are displayed until some are created.
Convert Tags to Categories
Use the Tag to Category Converter tool (found under Tools > Import) to convert selected tags into categories.
