Meta
tags are small pieces of information that can be attached
to a web page. They
are invisible to the user, but visible to the search
engines.
Meta
is the Greek word for “over”, and the “meta-tags”
were initially designed to carry all sort of
meta-information – that is “information-about”.
Using meta-tags for specifying keywords or a description
for a web page is not an HTML standard convention, but it
is a widely accepted use of the meta-tags.
There
are many meta-tag types, but from the search engines’
perspective, the most important are the “keywords”
meta-tag (carrying keywords associated with the content of
the web page) and the “description” meta-tag (that
provides a brief description of the page).
In
the beginning, search engines gave much weight to the
“keyword” and the “description” meta-tags, because
they helped to determine a web page’s relevancy related
to a search query. There was a time when a “smart” use
of meta-tags could make the difference between a good and
a poor positioning in the search engines’ listings.
However, those times are over…
The
misuse of meta-tags was the main reason for which search
engines do not rely on them so heavily any more.
Unscrupulous webmasters used meta-tags to mislead the
search engines in “believing” that a web page’s
content was related to a particular topic just to attract
traffic. Indeed, nobody can guarantee that the keywords
entered are describing the content of a web page, and one
can easily use popular keywords (like “sex”, or
“free pics”) to artificially inflate the number of
visitors.
However,
being one of the few techniques capable of helping search
engines to “understand” human-produced content,
meta-tags are still used by many search engines. It is
necessary to stress that no search engine relies heavily
on them any more, while some search engines ignore them
completely.
In
the past, meta-tag optimization was THE key-point in any
search engine optimization strategy. Nowadays, meta-tags
still matter, but other factors (like link popularity) are
far more important.
