“The World Wide Web Consortium (W3C), along with other groups and standards bodies, has established technologies for creating and interpreting web-based content. These technologies, which we call “web standards,” are carefully designed to deliver the greatest benefits to the greatest number of web users while ensuring the long-term viability of any document published on the web.”
— The Web Standards Project

Making your web site in conjunction with W3C Compliance serves the following benefits:

1. Increased cross-browser reliability – ensuring your website delivers the information correctly to all users.
2. Increased ‘Crawlability’ by Search Engine Bots.
3. Good working practice.
4. Easier to manage updates/changes.

If your web site is written in well formatted, complaint coding, the bots will have a much easier time crawling your website, and will the regard the content as more valuable than if had been bloated with unnecessary code.
