What is a Title Tag?
In html code, the title tag specifies the title of your Web page. It is code which is inserted into the header of your web page and looks like this:
< head > < title > Creating Title Tags for Search Engine Optimization & Web Usability < / title > < / head >
The World Wide Web Consortium describes the title as a required element in an HTML document:
The global structure of an HTML document - 7.4.2 The TITLE element
"Every HTML document must have a TITLE element in the HEAD section."
"Authors should use the TITLE element to identify the contents of a document. Since users often consult documents out of context, authors should provide context-rich titles. Thus, instead of a title such as "Introduction", which doesn't provide much contextual background, authors should supply a title such as "Introduction to Medieval Bee-Keeping" instead."
Many other tags can be placed within the header tag as well, including meta tags.
