Categories and tags in WordPress are always located on the right sidebar when writing a blog post, However, they can help to organise the content on your site, as well as help with SEO. They are also the two primary ways of grouping content on a WordPress site, with categories being general labels, while tags describe your posts in more detail. A category represents a subject matter or a group of subjects that are connected to each other in a particular way. The main contrast between categories and tags is the way in which you use them.  Tags are a great tool to identify a piece of content by several specified keywords best to describe your post. Tags are much more in-depth and indicate the individual topics the posts talk about.  I have used tags and categories in my posts to describe the current posts for the website.
