Validate Your Website’s HTML and xHTML Markup!

With the increasing compliance by browser vendors to adhere to (some) of the W3C document and CSS standards, it is ever-increasingly important to use markup (tags), attributes, and coding practices that adhere to these standards as well.

Specifying document type and character encoding and using supported tags and attributes for the version of HTML (4.01) or xHTML (1.0 or 1.1 Transitional or Strict) not only increases the likelihood of your pages rendering properly and bug-free across multiple browsers and operating platforms, but also aide in your website’s ability to be indexed by spiders and crawlers and is the most important step in organic search engine optimization.
