W3C Link Checker
» Check for broken links on any website.The World Wide Web Consortium (W3C® ) was created in October 1994, and is the chief standards body for HTML. When a new HTML specification (which defines how Web pages should be displayed by Web browsers) is approved by W3C, it is assigned a unique document type definition (DTD) and is called a DOCTYPE. To ensure your Webpage complies with HTML standards, you need to validate (test) each page according to the specific rules that apply to the HTML standard used to create it.
