Title tags play three very important roles as described below
* First and foremost title tags are very important from the search engine point of view. This is because all major and minor search engines place much weightage on these tags (and use these tags to gather information about an website) in comparison to all other aspects
* Secondly many major search engines like google and yahoo! display title tags of a web page as a heading in their SERPs (Search engine results page) followed by a breif description of the content were the keywords appear
* The third most important function of title tags is to help the user in finding out which page he is on. Almost all popular browsers including Microsoft Internet Explorer, display title tags on the top bar as well as the bottom. Firefox 1. 0 uses title tags to describe 'tabs'. This makes title tags extremely important from the web usability point of view as well.
