Maximizing Your Use of WordPress Tags
WordPress tags are very important and are similar to your categories, only they’re not necessarily there for navigation purposes. They’re more for sorting posts according to topics and identifying your content for search engines and visitors with keywords and phrases.
Using the tags makes it possible to have a list of “Tags” in your sidebar where people can click the different Tags to bring up all the Pages and Posts that have those particular tags. If you have a Search box, then the Tags are also used to retrieve results for the users specific search.
Tags are more specific than their category counterparts. Categories are broader, but tags dig down deeper to tell you specifically what’s inside a particular blog post. Whenever you add a new post, on the right side, you’ll see a box with the title “Tags“.
