7 Benefits of HTML validation
by Herman Drost
1. Web Site Accessibility - validating your html
code helps to pinpoint areas of potential blockage that could prevent
search engine spiders or visitors from accessing your website. When
you run your site through a code validator it may produce many errors
that need to be corrected so your pages will render well. i.e. include
text with your "alt" tags for every < img > tag.
Why should you do this?
-Allows your site to be accessible to a larger audience (vision
impaired, motor skill impaired, cognitive impaired)
-Allows your site to be accessed by wider range of devices (hand
helds, screen readers, text browsers, search engines)
-Is a requirement for Federal and State Government sites
2. Search engine friendly pages - clean and simple
code
enables search engines to spider your pages more quickly and
completely.
Here's an example:
What's wrong with this code?
< p keyword1 sentence, well written copy, etc.
< p > keyword2 paragraph with more choice content.
This code is missing a ">" The issue is not that the
page will necessarily get skipped altogether but that the
"keyword1" sentence looks like part of the tag - like a tag
attribute. So the words in the "keyword1" sentence probably
won't be included in the search engines computations, even though
the page itself will be indexed.
Once a spider sees a correct tag further along in the page, then
it's back on course. So, the keyword2 paragraph would make it.
3. Faster Loading - if your web page contains html
errors it will take a longer time for the search engines to spider it,
therefore slowing the loading time. If your page doesn't load in
under 10 seconds your visitors will click away to your
competitors' sites.
4. Less load on servers - clean and simple code
won't tax your server as much as a site which has complicated code
or contain many nested tables. Cascading style sheets (CSS) will
greatly reduce the amount of code within your web pages. This will
also cut down on the amount of web space and bandwidth used thus
saving you money for hosting your site.
5. Easier to update and maintain web site - with no
mistakes in your html code it is easier and faster to make changes to
your web pages. For web site designers, this means you will save time
and money when maintaining clients' sites.
6. Browser compatibility - validated code ensures
your site is compatible with the current browsers and future browsers.
You might say "well, it looks fine in Internet Explorer, so why
bother with any other browsers?" Current browsers will continue
to update their rules and future browsers will make sure they are html
compliant.
7. Access more visitors - if you ensure your web
pages appear correctly in all the major browsers you will be able to
reach a larger audience which then increases the potential of your
site to make more sales.
