W3C Compliancy

W3C Compliancy

What does W3C compliance mean and why is W3C compliancy so important? Can you answer in plain English, so a mere mortal can understand?

Hello Stan, thanks for sending the question about W3c compliance in.

The W3 part of the acronym stands for WWW, or World Wide Web and the C part of W3C stands for Consortium, so W3C means “World Wide Web Consortium”.

W3C is a combination of member organisations that work together to develop the standards for the World Wide Web (WWW).

So, if a site is W3C compliant, it passes the compliancy standards set out by the W3 Consortium.

How do I know if my site is W3C compliant?

W3C offer free online compliance checking tools which can be found at:

http://validator.w3.org/ (to ensure HTML or XHTML W3C compliancy) and http://jigsaw.w3.org/css-validator/ (to ensure CSS compliancy).

If your site is not fully compliant for your markup language and/or your CSS,  W3C tell you where you have gone wrong and how to fix the issue, in the case of the Markup Language.

Google take source code compliancy into consideration in their algorithm and although Yahoo and MSN have not yet followed suit, a fully compliant page is easier for a search engine spider to read, so compliancy will give you advantages on all of the top three search engines.

I hope that’s plain enough Stanley, but if you have any more W3C compliance related questions, don’t hesitate to get back in touch.
