HTML validation is done mainly to ensure that webpages follow the HTML standards and rules set by W3C (World Wide Web Consortium). A webpage with correct HTML helps

  • to increase the speed of the website
  • search engines to index webpages more easily
  • to increase the traffic of the site by giving access to more visitors to the site
  • to reduce the load on the server
  • in giving similar look and feel to the webpages in all browsers
  • to easily update and maintain the site

Therefore all pages in a website be it drupal or non drupal, should be validated and must be correct according to W3C standards.

HTML validation can be done by giving the URL of the web pages in a validator "http://validator.w3.org." The validator validates and displays whether the webpage contains any HTML errors.
