It checks whether your site works with the W3C internet standard for HTML/XHTML. The process of verifying whether a document actually follows the rules for the language(s) it uses is called validation. If your site passes the validation, it will help you to become a higher Google pagerank (page rating given by Google) and to become higher in the search results (SEO).
