An HTML title is the text that shows on the top blue bar of your browser. The text is usually a description of what your page is about. Some pages do not have anything in the title, so it may just say "Untitled." The title is also used as the words to describe your page when someone adds it to their "Favorites" or "Bookmarks" lists. Titles are a very important component in marketing because search engines use them in calculating page importance.
