That meta tag prevents Google from publicly showing their cached version of the page. In practice this means the "Cached" link, within the results, doesn't appear when a given page asks Google to NOARCHIVE -- which I believe can be 'asked for' via either the meta tag or via a special response header. Edit: Yeah, 'noarchive' can be specified via the meta tag or via header. Also available to you are a handful of other directives such as NoIndex, NoFollow, NoArchive, NoSnippet, NoTranslate, etc... See these links for more in-depth info about the directives & which search engines support what: Directives & Usage in Meta tags - http://noarchive.net/meta/ http://noarchive.net/meta/ Usage in Response Headers - http://noarchive.net/xrobots/ http://noarchive.net/xrobots/
