W3C validation helps you to get better rankings in search engines.World Wide Web Consortium (W3C) allows internet users to check HTML and XHTML documents for well-formatted markup.Markup validation is an important step towards ensuring the technical quality of web pages.Make sure your codes and styles validate across the board.That means they have to meet the "strict" standards set by the W3C Organization and pass a variety of validations for CSS and XHTML. Some only check CSS, others XHTML, and others for accessibility.
The concept of "well formed" is close to what is required here.
Since repair techniques vary among user agents, authors cannot assume that content will be accurately parsed into a data structure or that it will be rendered correctly by specialized user agents, including assistive technologies, unless the content is created according to the rules defined in the formal grammar for that technology.
In markup languages, errors in element and attribute syntax and failure to provide properly nested start/end tags lead to errors that prevent user agents from parsing the content reliably.
If the content cannot be parsed into a data structure, then different user agents may present it differently or be completely unable to parse it.
Some user agents use "repair techniques" to render poorly coded content.
In simple terms, validation ensures that your website complies with the standards accepted by most web designers.
