Meta Revisit Tag.
Historically, the Meta Revisit Tag was believed to specify how often a search engine should visit a site for re-indexing. Although not proven, webmasters could indicate the frequency of how often their content changes and is ready for a re-index by search engines. These days, much as one would like to, one cannot command the re-visit frequency of any search engine, unless you go the PFI route.
this is the command though.
<HEAD> <META name="Revisit-After" content="X Days"> </HEAD> Note: X indicates the number
