A single title element is required in the head element and is used to set the text that most browsers display in their title bar. The value within a title is also used in a browserís history system, recorded when the page is bookmarked, and consulted by search engine robots to help determine page meaning. In short, it is pretty important to have a syntactically correct, descriptive, and appropriate page title. Thus, given
<title>Simple HTML Title Example</title>
When a title is not specified, most browsers display the URL path or filename instead:
Only one title element should appear in every document, and most user agents will ignore subsequent tag instances. You should be quite careful about making sure a title element is well formed because omitting the close tag can cause many browsers to not load the document.
Beyond character set concerns, think twice before using a special character such as a colon (:), slash (/), or backslash (\) in a document title. An operating system might have a problem with such a title if the document is saved to the local system. For example, the colon isnít allowed within Macintosh file-names, and slashes generally arenít allowed within file-names, because they indicate directories. Most modern browsers remove such special characters and reduce them to spaces during the Save process. To be on the safe side, use dashes to delimit items in a page title
For an entity to be displayed properly you need to make sure the appropriate character set is defined and that the browser supports such characters; otherwise, you may see boxes or other odd symbols in your title
To set the appropriate character set, you should include a tag before the page title even though traditionally title is considered the first element.
