HTML Checking for Large Sites

Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.

Element “title” must not be empty.

The <title> element, used to define the document’s title, is required and must not be empty.

Example:

<html>
  <head>
    <title>Automated Website Validator</title>
  </head>
  <body>
    <p>...</p>
  </body>
</html>
