WordPress tags are the great way to group related posts together and briefly describe a post to the reader. By default, each post comes with a Tag pane.
To add tags to a Post (or Page*), follow these steps:
- In your Post (Page*) screen, type the tag word in the Tags field on the right and click the Add button. You can add as many tags as you want.
- Make sure you’ve clicked Publish/Update button when your Post (Page*) is ready.
More detailed information about WordPress tags you can find here.
*Sometimes, pages and other post types might also come with the tags functionality.
