I learned from a blog post that Google is now accepting a new meta tage called unavailable-after. This new function will essentially list a page of your website until a certain date and then delete it from its index after that date. Perfect if you have a special offer on your site that someone must buy before a specific date. Also good if you are holding workshop registrations online and don’t want to feature the event after a certain date.

But what intrigued me about this particular addition is that meta tags are pretty much bottom of the totem pole when it comes to assisting with positioning your website in the serps. Google is now resorting once again to meta tags. Could this be a reversal in time where it was once meta tags that ruled the earth?
