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. The articles below explore this in more detail:

Meta Tags Revisited

The Search Engine Report, Dec. 5, 2002

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. The article below talks about this in more depth and provides some links to help files. Search Engine Watch members should follow the link from the article to the members-only edition for extended help on the subject.

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.
