Google Introducing New Meta Tag for Webmasters

SMS Text

Google will be coming out with a new meta tag for webmasters which identifies pages that have a time restriction or are time sensitive.

The ‘unavailable_after’ meta tag will soon be recognized by Google according to Dan Crow, Director of Crawl Systems at Google and Jill Whalen of High Rankings.

Google is coming out with a new tag called “unavailable_after” which will allow people to tell Google when a particular page will no longer be available for crawling. For instance, if you have a special offer on your site that expires on a particular date, you might want to use the unavailable_after tag to let Google know when to stop indexing it. Or perhaps you write articles that are free for a particular amount of time, but then get moved to a paid-subscription area of your site.

  • Thanks for the heads up this will be really useful on several of my sites and I really hope eBay utilizes this as I land on excessive amounts of closed auction pages from google.

    What has been the norm with yahoo and msn following suit when google introduces a new meta tag?

  • Will there be an option to redirect after xx/xx/xxxx? Just being removed from the index sounds like a loss in potential exposure to me.

  • Thanks for the advance notice. Would be good way to remove old content from index faster than waiting for the old page to be picked up as a redirect hopefully.

  • it will be usefull for some webmasters that design a website for example for a Fair or an exhibitaion that thay do not need their website for a long time.
    tnx google.!

  • Good info. Thanks.


  • HI

    Thanks for sharing the news !


  • Really it is a nice information. This helps webmasters a lot.

  • We have to keep in mind that any web page may be revisited or searchable even if it is out of dated or for any reasonable matter, and even if this web page is an offer or an auction….

    so i think this tag is not important.
    if you contradict with me, please clarify and note me

  • Thanks for that information.
    I think this tag would be useful to only a small minority of webmasters.

    Google’s blog says that the page will be removed from it’s index roughly one day after the date given by this tag.
    But it says nothing about re-indexing, I doubt that they will place any priority on the re-indexing of such pages as any such policy would lead to wide-spread abuse.

    So, I can see how this tag would be important for special pages that contain information thats of use only for a certain time (special offers, traffic data, etc).

    But I think it would only be useful if the page itself would also cease to exist after that time. Great if you create a new Christmas Special offer page every year and delete it come January, for example.

    But it’d probably quite harmful to your rankings if you regularly change the content on a page that stays all-year round.

    Mis-use this tag at your peril it seems!

  • This is nice. This meta tags is useful for webmasters

  • This sounds like an excellent Idea we will certainly make us of it when available.
