overlook a very important aspect of web site promotion: the validity
of the HTML code.
valid HTML code?
Most web pages are written in HTML.
As for every language, HTML has its own grammar, vocabulary and
syntax, and every document written in HTML is supposed to follow
these rules. Like any language, HTML is constantly changing.
As HTML has become a relative complex language, it's very easy to
make mistakes. HTML code that is not following the official rules is
called invalid HTML code.
Why is valid HTML code
Search engines have to parse the
HTML code of your web site to find the relevant content. If your
HTML code contains errors, search engines might not be able to find
everything on the page.
Search engine crawler programs obey
the HTML standard. They only can index your web site if it is
compliant to the HTML standard. If there's a mistake in your web
page code, they might stop crawling your web site and they might
lose what they've collected so far because of the error.
Although most major search engines
can deal with minor errors in HTML code, a single missing bracket in
your HTML code can be the reason if your web page cannot be found in
search engines. If you don't close some tags properly, or if
some important tags are missing, search engines might ignore the
complete content of that page.
How do we check the validity of
your HTML code?
The code for
was checked using W3C approved validation processes. Although
not all HTML errors will cause problems for your search engine
rankings, some of them can keep web spiders from indexing your web
pages. Valid HTML code makes it easier for search engine
spiders to index your site so you should make sure that at least the
biggest mistakes in your HTML code are corrected.
In addition to code corrections,
First Webs recommends the use of CSS external files be used when
of <body> section, it should be so moved. Both these processes
help search engines get to the "meat" of the content early, and help
improve the ratio of visibile text to total text in the web page.
Higher ratios are always better.
