Will w3c clean code help in ranking?

[mikkomiss]

What do you guys think? does cleaning your website's HTML and CSS help search spiders?

I think it does, they read the HTML on your page, and I think it's very important to have consistent and error free HTML/CSS.

It's not always possible to have valid HTML though, especially with dynamically generated content.

There have been many arguments as to whether or not Google search engine ranking factors look for a clean code in a website. The W3C Schools have brought forth a very popular and widely used tool, called the W3C Validation and the CSS Validation. Basically, both these tools look at your HTML and CSS Style Sheet that code your website for any errors that may arise. This free tool will scan all of your code to make sure it is compliant with current web standards and free or any errors.
