HTML Checking for Large Sites

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

Element “head” is missing a required instance of child element “title”.

The <head> section of an HTML document contains metadata about the document, and as a minimum it must include a <title> tag defining the document title.

Common causes for this issue are forgetting to define the <title>, or duplicated <head> sections where one of them does not include the title.

Here’s an example of a minimal HTML document including the title:

<!DOCTYPE html>
<html>
  <head>
    <title>Don't panic! This is the title</title>
  </head>
  <body>
    <p></p>
  </body>
</html>
