Google’s Unavailable_After META Tag has Arrived
July 28th, 2007
Google’s Dan Crow announced today that the Unavailable_After META tag is now live:
“We have introduced a new META tag that allows you to tell us when a page should be removed from the main Google web search results: the aptly named unavailable_after tag. This one follows a similar syntax to other REP META tags. For example, to specify that an HTML page should be removed from the search results after 3pm Eastern Standard Time on 25th August 2007, simply add the following tag to the first section of the page:
<META NAME=”GOOGLEBOT” CONTENT=”unavailable_after: 25-Aug-2007 15:00:00 EST”>
The date and time is specified in the RFC 850 format.
This information is treated as a removal request: it will take about a day after the removal date passes for the page to disappear from the search results. We currently only support unavailable_after for Google web search results. After the removal, the page stops showing in Google search results but it is not removed from our system.”
