Online HTML code validator



The valid code is important for many reasons. If your validation check shows errors, these problems could damage this web page's search engine rankings as well as cause viewing problems for visitors. As a result your website might not display properly on all the machines or in all the browsers. It can as well freeze the page and even crash the visitors browser. Many engines cannot properly catalog or index a site that has serious HTML errors. This can greatly reduce the amount of traffic your web site receives from search engines. Properly written HTML will render better, render on more browsers, and render faster than HTML with errors. This free online HTML validator will check your HTML source code for errors and offer suggestions for correcting the errors.
