Validation is important, and will ensure that your web pages are interpreted in the same way (the way you want it) by various machines, such as search engines, as well as users and visitors to your webpage. Conforming to standards and regulations is one of the many ways you can make your website universally understood. Make sure your codes and styles validate across the board.
Validating your WordPress site means more than just checking the front page for errors. With the modular Themes and template files in WordPress, while you may fix all the errors associated with the index.php and sidebar.php when viewing your front page, errors may still lie within any other template files such as single.php, page.php, archives.php, or category.php. Validate these page views as well to make sure you cover all the template files.
A validator is a software program that can check your web pages against the web standards.When using a validator to check HTML, XHTML or CSS documents, the validator returns a list of errors found, according to your chosen standard.Make sure you make it a habit to validate all your web pages before publishing.
