Tag is used to label or give an identification to your post. It gives your visitors an idea of what your post is about. Another benefit of using a tag is to help your visitors explore your blog content:
Example: If you add a tag “Sports” to the posts that are about sports. When a visitor who is interested in sports comes to your blog, he or she can click on the tag “Sports” and all the posts that have this tag would display instantly.
To add tags to your blog posts, you can follow these steps:
Go to the blog post you wish to edit and then click on Edit this Page.
Find the Settings section in your blog post panel.
Click on the Add a Tag text box at the bottom of your blog post settings panel.
Write a tag name for your post then press Enter on your keyboard to save.
NB! A tag should contain words only, the symbol # is not required.
