When you click on the "New Post" button on your Blogger dashboard, you are sent to a page with a large text box for composing your post. Scroll down to the bottom of this text box to see a section titled "Labels for this post" with a smaller text box next to it. You can place single words or longer phases in this box; whatever you choose to write here, it should reflect what your post is about. While labels are an optional, added feature to your blog -- one that benefits both you, the author, and your readers -- tags are a standard part of your website. This is because they are a part of the HTML, the computer language used to build your website. In fact, HTML tags are even used to build and give labels their functionality on your website.
