How to Work with Tags
Tags are useful in grouping related posts together. It is more specific compared with Categories.
Like categories, tags help to organize the post on your site as well as provide searchable keywords that make it easier for users to find your content. Tags are more descriptive than categories and are completely optional to your post. To add a tag, simply go to the tag box on the edit post screen. You can type the name and hit add, or by hitting enter on your keyboard. You can add multiple tags at a time by putting commas in between each word that you want to be a tag. When you are done hit publish on your post. Depending on your theme and widgets, your tags can be shown on your posts or in the side bar which will lead to any other posts that you have used these tags in.
