Something like < META name='unavailable_after' content='Wed, 01 Aug 2007 00:00:01 GMT'>
By specifying this tag, webmasters can tell Google not to index a particular page after the specified date OR consider the given page as stale. This would be appropriate for promotional pages where the promotions expire after a given time. This would help unclog the search engine indexes of irrelevant data.
It would be great to have such tag(s) in use. |
