Tag, Tagging:
Tags are basically
very much the same thing as keyword
s. The
minor difference could be said to lie in the respective
usage.
-
Keywords are
part of the standard website content
, the text, the headlines
, image descriptions,
etc.
-
A Tag rather
would refer to labelling things with descriptive words
that groups them in a certain category so they can be
easily found when needed. For a website the author
could chose one or more of the keywords that he thinks
would best describe and classify his website’s
content. It’s like sorting bills in different
category folders and tagging each folder with “tax
bills”, “car bills”, “recreation bills” etc. If you
then want to find an earlier tax bill you could find it
more easily because you had only to look in the tax
bill folder instead of search through all
bills.
In Internet marketing
Tags are used when entering a website to one’s private or
public bookmarks on
social bookmarking
sites. The sites
are bookmarked together with one or more descriptive tags
which sort them in specific categories and make it easier
to find them at a later point.

This is the homepage of
del.icio.us
, a popular social bookmarking site. You can see
the 4 most popular bookmarks for this day. Underlined in
red are the tags which are supposed to represent the
site’s content. The Tags in line 1 and 3 (#105 and #111)
are enhanced for better
readability.
The same holds true
for blog
entries which can
be assigned to certain categories. Those categories can serve
as tags as well.

One post of Charles Heflin’s
SEO 20/20
Blog. The tags
describe the categories to which the entry would
fit.
[Tag is
of unclear origin, probably comes from Norwegian
tagge
and Swedish
tagg
= pointed, protruding
part]
