Web standards serve an important purpose. By building websites and browsers that comply with the standards, we can be assured that the person viewing our website will be able to view and browse as accurately and clearly as possible.

If your site does not comply with these standards, then it is quite possible that some visitors may not be able to view or navigate your site correctly, and some visitors may not be able to view or navigate your site at all.

Many search engine spiders can be very sensitive, and, just like other visitors and browsers, some search engines may not be able to read or navigate your site either.

Remember, the good news is that the standards are pretty clear, which means that by following the web standards, we can rest assured that the maximum number of both visitors and search-engine spiders (bots) will be able to view our sites.

These standards as set by the W3C (World Wide Web Consortium).

In addition to information, guidelines, and specifications, they also provide two tools of great importance to anyone with a website: validators for both CSS and HTML. These validators will check any page on the web for compliance with standards, providing solid information and suggestions regarding any errors they find in your page.
