7 Benefits of HTML Validation
Copyright Herman Drost 

You may not bother with html validation or writing simple
and clean code when designing your web site. Later you may
find your site is slow loading, appears incorrectly in the
main browsers and does not rank well for the major search
engines.

Now there are sites that still do rank well even though the
html code has many errors. This is because most of the
current major browsers are still very forgiving of html
mistakes, however future browsers will become more html
compliant as the Internet advances. Sites that have not
bothered with html code validation will then fall by the
wayside or take time and money to be corrected.

That's why you should be take the necessary steps NOW to
make sure that the code on your web site is validated.

What is HTML validation?

This is the process that analyzes an HTML document in
comparison to standard HTML rules, identifying errors and
non-standard codes. Web pages are rendered using HTML
(Hyper Text Markup Language). As with any language there
are rules and standards that should be followed. For
example the HTML 4.01 Specification (rules and standards)
are available at http://www.w3.org/TR/html4/. You can check
the html validation of your web page by entering your url
at: http://validator.w3.org/
