Want to get
a top ranking in search engines? No problem! All you need to
do is add a few magical "meta
tags" to your web pages, and you'll skyrocket to the top
of the listings.If
only it were so easy. Let's make it clear:
- Meta tags
are not a magic solution.
- Meta tags
are not a magic solution.
- Meta tags
are not a magic solution.
Meta
tags have never been a guaranteed way to gain a top ranking
on crawler-based search engines. Today, the most valuable
feature they offer the web site owner is the ability to
control to some degree how their web pages are described
by some search engines. They also offer the ability to
prevent pages from being indexed at all. This page explores
these and other meta tag-related features in more depth.
Meta
Tag Overview
What
are meta tags? They are information inserted into the "head" area
of your web pages. Other than the title
tag (explained below), information in the head area
of your web pages is not seen by those viewing your pages
in browsers. Instead, meta information in this area is
used to communicate information that a human visitor may
not be concerned with. Meta tags, for example, can tell
a browser what "character set" to use or whether a web
page has self-rated itself in terms of adult content.Let's
see two common types of meta tags, then we'll discuss exactly
how they are used in more depth:

In
the example above, you can see the beginning of the page's "head" area
as noted by the HEAD tag -- it ends at the portion shown
as /HEAD.Meta
tags go in between the "opening" and "closing" HEAD tags.
Shown in the example is a TITLE tag, then a META DESCRIPTION
tag, then a META KEYWORDS tag. Let's talk about what
these do.
The
Title Tag
The
HTML title tag isn't really a meta tag, but it's worth
discussing in relation to them. Whatever text you place
in the title tag (between the TITLE and /TITLE portions
as shown in the example) will appear in the reverse bar
of someone's browser when they view the web page. For instance,
within the title tag of this page that you are reading
is this text:
How
To Use HTML Meta Tags
If
you look at the reverse bar in your browser, then you should
see that text being used, similar to this:
 Some
browsers also supplement whatever you put in the title
tag by adding their own name, as you can see Microsoft's
Internet Explorer doing in the picture above.The
title tag is also used as the words to describe your page
when someone adds it to their "Favorites" or "Bookmarks" lists.
For instance, if you added this page to your Favorites
in Internet Explorer, it would show up like this:

But
what about search engines! The title tag is crucial for
them. The text you use in the title tag is one of the most
important factors in how a search engine may decide to
rank your web page. In
addition, all major crawlers will use the text of your
title tag as the text they use for the title of your page
in your listings. For
example, this is how Teoma lists the page you are reading:

You
can see that the text "How To Use HTML Meta Tags" is used
as the hyperlinked title of this page's listed in Teoma's
results.In
review, think about the key terms you'd like your page
to be found for in crawler-based search engines, then incorporate
those terms into your title tag in a short, descriptive
fashion. That text will then be used as your title in crawler-based
search engines, as well as the title in bookmarks and in
browser reverse bars. The
Meta Description Tag
The
meta description tag allows you to influence the description
of your page in the crawlers that support the tag.
Look
back at the example of
a meta tag. See the first meta tag shown, the one that
says "name=description"? That's the meta description tag.
The text you want to be shown as your description goes
between the quotation marks after the "content=" portion
of the tag (generally, 200 to 250 characters may be indexed,
though only a smaller portion of this amount may be displayed).
For
this page you are reading, I would like it described in
a search engine's listings like this:
Will
this happen? Not with every search engine. For example,
Google ignores the meta description tag and instead will
automatically generate its own description for this page.
Others may support it partially. For instance, let's see
again how this page is listed in Teoma:

You
can see that the first portion of the page's description
comes from the meta description tag, then there's an ellipse
(.), and the remaining portion is drawn from the body copy
of the page itself.
In
review, it is worthwhile to use the meta description tag
for your pages, because it gives you some degree of control
with various crawlers. An easy way to do this often is
to take the first sentence or two of body copy from your
web page and use that for the meta description content.
The
Meta Keywords Tag
The
meta keywords tag allows you to provide additional text
for crawler-based search engines to index along with your
body copy. How does this help you? Well, for most major
crawlers, it doesn't. That's because most crawlers now
ignore the tag.
The
meta keywords tag is sometimes useful as a way to
reinforce the terms you think a page is important for ON
THE FEW CRAWLERS THAT SUPPORT IT. For instance, if you
had a page about stamp collecting -- AND you say the words
stamp collecting at various places in your body copy --
then mentioning the words "stamp collecting" in the meta
keywords tag MIGHT help boost your page a bit higher for
those words.
Remember,
if you don't use the words "stamp collecting" on the page
at all, then just adding them to the meta keywords tag
is extremely unlikely to help the page do well for the
term. The text in the meta keywords tag, FOR THE FEW CRAWLERS
THAT SUPPORT IT, works in conjunction with the text in
your body copy.
The
meta keyword tag is also sometimes useful as a way to help
your page come up for synonyms or unusual words that don't
appear on the page itself. For instance, let's say you
had a page all about the "Penny Black" stamp. You never
actually say the word "collecting" on this page. By having
the word in your meta keywords tag, then you may help increase
the odds of coming up if someone searched for "penny black
stamp collecting." Of course you would greater increase
the odds if you just used the word "collecting" in the
body copy of the page itself.
Here's
another example. Let's say you have a page about horseback
riding, and you've written your page using "horseback" as
a single word. You realize that some people may instead
search for "horse back riding," with "horse back" in their
searches being two separate words. If you listed these
words separately in your meta keywords tag, THEN MAYBE
FOR THE FEW CRAWLERS THAT SUPPORT IT, your page might rank
better for "horse back" riding. Sadly, the best way to
ensure this would be to write your pages using both "horseback
riding" and "horse back riding" in the text -- or perhaps
on some of your pages, use the single word version and
on others, the two word version.
I'm
using all these capital letters on purpose. Far too many
people new to search engine optimization obsess with the
meta keywords tag. FEW crawlers support it. For those that
do, it MIGHT! MAYBE! PERHAPS! POSSIBLY! BUT WITH NO GUARANTEE!
help improve the ranking of your page. It also may very
well do nothing for your page at all. In fact, repeat a
particular word too often in a meta keywords tag and you
could actually harm your page's chances of ranking well.
Because of this, I strongly suggest that those new to search
engine optimization not even worry about the tag at all.
Even
those who are experienced in search engine optimization
may decide it is no longer worth using the tags. Search
Engine Watch doesn't. Any meta keywords tags you find in
the site were written in the past, when the keywords tag
was more important. There's no harm in leaving up existing
tags you may have written, but going forward, writing new
tags probably isn't worth the trouble.
Still
want to use the meta keywords tag? OK. Look back at the
opening example. See the second meta tag shown, the one that
says "name=keywords"? That's the meta keywords tag. The
keywords you want associated with your page go between
the quotation marks after the "content=" portion of the
tag.
Inktomi
says that you should include up to 25 words or phrases,
with each word or phrase separated by commas. More advice
from Inktomi can be found on its Content
Policy FAQ.
FYI,
in the past, when the tag was supported by other search
engines, they generally indexed up to 1,000 characters
of text and commas were not required.
Meta
Robots Tag
One other meta
tag worth mentioning is the robots tag. This lets you specify
that a particular page should NOT be indexed by a search
engine. To keep spiders out, simply add this text between
your head tags on each page you don't want indexed. The format
is shown below (click on the picture if you want to copy
and past the HTML for your own use):

You do NOT need
to use variations of the meta robots tag to help your pages
get indexed. They are unnecessary. By default,
a crawler will try to index all your web pages and will try
to follow links from one page to another.
Most
major search engines support the meta robots tag. However,
the robots.txt convention of blocking indexing is
more efficient, as you don't need to add tags to each and
every page. See the Search
Engines Features page for more about the
robots.txt file. If you use do a
robots.txt file to block indexing,
there is no need to also use meta robots tags.
The
meta robots tag also has some extensions offered by particular
search engines to prevent indexing of multimedia content.
Other
Meta Tags
There
are many other meta tags that exist beyond those explored
in this article. For example, if you were to view the source
code of this web page, you would find "author," "channel" and "date" meta
tags. These mean nothing to web-wide crawlers such as Google.
They are specifically for an internal search engine used
by Search Engine Watch to index its own content.
There
are also "Dublin Core" meta tags. The intent is that these
can be used for both "internal" search engines and web-wide
ones. However, no major web-wide search engine supports
these tags. More about them can be found below:
How
about the meta revisit tag? This tag is not recognized
by the major search engines as a method of telling them
how often to automatically return. They
have never supported it.
In
Conclusion
Overall,
just remember this. Of all the meta tags you may see out
there:
-
Meta
Robots: This tag enjoys full support, but you
only need it if you DO NOT want your pages indexed.
-
Meta
Description: This tag enjoys much support, and
it is well worth using.
-
Meta
Keywords: This tag is only supported by some
major crawlers and probably isn't worth the time
to implement.
-
Meta
Everything Else: Any other meta tag you see is
ignored by the major crawlers, though they may be
used by specialized search engines.
