Google Plans “unavailable_after” Tag
By Kai Blum
Search engine marketing expert Jill Whalen summarized on her blog a presentation by Dan Crow, director of crawl systems at Google, at the Search Engine Marketing New England conference. There’s lots of valuable advice in her blog entry, but one piece of information is particularly interesting:
- 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.
Anyone who publishes seasonal pages and online promotions that expire on a certain date as well as pages that announce specific events should include this tag, because it will prevent search engine user frustration that comes along with too much clutter in organic search results and with accessing expired information.
This new tag makes so much sense that it’s surprising that it wasn’t introduced years ago.
