Google does not use the Keywords Meta Tag for web ranking

Q&A from Google Webmaster Central

Q: Does Google ever use the “keywords” meta tag in its web search ranking?
A: In a word, no. Google does sell a Google Search Appliance, and that product has the ability to match meta tags, which could include the keywords meta tag. But that’s an enterprise search appliance that is completely separate from our main web search. Our web search (the well-known search at Google.com that hundreds of millions of people use each day) disregards keyword meta tags completely. They simply don’t have any effect in our search ranking at present.

Q: Why doesn’t Google use the keywords meta tag?
A: About a decade ago, search engines judged pages only on the content of web pages, not any so-called “off-page” factors such as the links pointing to a web page. In those days, keyword meta tags quickly became an area where someone could stuff often-irrelevant keywords without typical visitors ever seeing those keywords. Because the keywords meta tag was so often abused, many years ago Google began disregarding the keywords meta tag.

Q: Does Google ignore all meta tags?
A: No, Google does support several other meta tags. This meta tags page documents more info on several meta tags that we do use. Even though we sometimes use the description meta tag for the snippets we show, we still don’t use the description meta tag in our ranking.

Q: Does this mean that Google will always ignore the keywords meta tag?
A: It’s possible that Google could use this information in the future, but it’s unlikely. Google has ignored the keywords meta tag for years and currently we see no need to change that policy.
