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.

The W3C provides a validation process that checks website code adheres to the formatting standards designed and implemented by the W3C. When planning a professional website, you need to understand the importance of having it W3C validated. If you fail to validate the pages of your website against W3C standards, your website will be affected by a higher rate of errors or poor traffic caused by poor visual formatting and readability.
