I just want to ask experts what is W3C validation in SEO? What is the role of W3C validation in SEO?

Hi Melissa Feeney,
W3C validation stands for World Wide Web Consortium.It's functionality is to check the validity of Web documents like HTML, XHTML etc. However, in layman terms we can say that it's the process of checking a Web document against Document Type Definition.
Website that are W3C have better friendliness and accessibility,easy to edit and maintain.Also it's important to use W3C conventions as much as possible and ensures that website work on other browsers like FireFox, Chrome, IE etc.
Any suggestions would be appreciated
Thanks !![]()
