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.

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).

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.

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.

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. If you use do a robots.txt file to block indexing, there is no need to also use meta robots tags.

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.
