Having valid HTML helps search engines better understand what your web page is about and makes it easier for them to send you qualified traffic. With valid HTML your web pages will load faster and search engines will be able to rank your web pages much easier! In addition to validating your source code, our HTML validation tool will make every attempt possible to comply with current W3C HTML standards to help ensure compatibility with all major search engines and Internet browsers.
The HTML Validator is a HTML/XHTML validation tool that corrects errors no other validation resource we know of is currently correcting. Most validation services only tell you in some "cryptic language" what is wrong with your web page leaving you to figure out what to do to correct those problems.
Not only will this tool validate your web page and report the errors found, but it will also make every attempt possible to automatically correct these errors for you! This said, no other HTML validation tool we know of has considered search engines for their validation process.
The HTML Validator tool below will automatically upgrade older HTML to HTML5 when possible and will correctly install missing HTML DOCTYPE declarations, titles and meta tags into your HTML/XHTML source code for you! Using this tool will NOT alter your live website making this tool 100% safe for anyone to use.
