Death Of A Meta Tag
The Rise & Fall Of The Meta Keywords Tag

For those unaware, the meta keyword tag is a way to insert text into an HTML page that is not visible when the page is viewed through a browser. Some search engines have read the content of the tag and associated the words within it along with the page's regular body copy.

The first major crawler-based search engines to use the meta keywords tag were Infoseek and AltaVista. It's unclear which one provided support first, but both were offering it in early 1996. When Inktomi launched in mid-1996 through the HotBot search engine, it also provided support for the tag. Lycos did the same in mid-1997, taking support up to four out of the seven major crawlers at the time (Excite, WebCrawler and Northern Light did not provide support).

The ascendancy of the tag did not last after 1997. Experience with the tag has showed it to be a spam magnet. Some web site owners would insert misleading words about their pages or use excessive repetition of words in hopes of tricking the crawlers about relevancy. For this reason, Excite (which also owned WebCrawler) resisted added support. Lycos quietly dropped its support of the tag in 1998, and newer search engines such as Google and FAST never added support at all.

After Infoseek (Go.com) closed in 2000, the meta keywords tag was left with only two major supporters: AltaVista and Inktomi. Now Inktomi remains the only one, with AltaVista having dropped its support in July, the company says.

"In the past we have indexed the meta keywords tag but have found that the high incidence of keyword repetition and spam made it an unreliable indication of site content and quality. We do continue to look at this issue, and may re-include them if the perceived quality improves over time," said Jon Glick, AltaVista's director of internet search.
