If you’ve already learned about categorizing your posts, tags should be an easy step. “Tags are similar to categories, but they are generally used to describe your post in more detail.” – WordPress.com. If you are writing a blog post under the category “Horses” and your post is about brands of horse feed, some of your tags might include Nutrena, Max-E-Glo and etc.
You can add tags directly from the post you are working on. You will see a Tags box on the right side. Type your tags of choice into the box and click the “Add” button.
TIP: Add multiple tags at a time by placing commas between each tag.
To save your changes, click the “Publish” button.
