What is the W3C Validation? how it can effect my website?

[RH-Calvin]

The Markup Validation Service is a validator by the World Wide Web Consortium (W3C) that allows Internet users to check HTML and XHTML documents for well-formed markup. Markup validation is an important step towards ensuring the technical quality of web pages. However, it is not a complete measure of web standards conformance. Though W3C validation is important for browser compatibility and site usability, it has not been confirmed what effect it has on search engine optimization.

W3C stands for Wide Web Consortium, a company that develops standards for code on the web. Validation works to check the HTML code for proper markup; thus making sure that all pages of a website are built in accordance with Web standards. If your website follows these standards, you have a better chance that your website will be able to work on different browsers and different operating systems.

The biggest reason that many SEOs do not put much emphasis on W3C validation is because Matt Cutts, head engineer of Google search, says himself that W3C validation has no affect on SEO. Cutts gave a few different reasons to support this claim:

Still Great Content*****– The biggest reason that Cutts has for supporting this argument is that many browsers do a good job working with broken code. Users can usually understand broken code just fine, even if it is not perfect, so it wouldn’t make sense for these tiny mistakes to affect a website’s position on a SERP. Danny Sullivan of Search Engine Land who helped Cutts answer this question compared this to a grammatical error. Every once and a while you read an article with a grammatical error, but you can usually still understand the article, right?

Google Doesn’t Validate*****– Another reason that many SEOs do not put a large emphasis on W3C validation is the idea that many major sites don’t validate. These sites include Google, Amazon, and Twitter. It is clear that these sites believe in great content (as do Google algorithms) more so than perfect code.

Hello,

The Markup Validation Service is just a validator by the World Wide Web Consortium (W3C) which enables users to assess HTML and XHTML files for Indices mark up. Investigation is a significant step towards ensuring that the quality of website pages. It is perhaps not a measure of web standards conformance. Though W3C investigation is essential for browser compatibility and site usability, so it's not yet been affirmed what effect it's on search engine optimisation.

W3C Validator doesn't have much to do with SEO.

The Validator checks the HTML or CSS code of a site and returns a report of mistakes in the code, where the code doesn't follow the standard of HTML or CSS.

It doesn't give any ranking of the search engine optimization (SEO). Valid code is always better than code with mistakes, but I doubt that code validity has any significant impact on SERP.
