Let’s say there is content which must not appear on Google after a certain date. Like an event page, a concert with specific dates etc.

Google, for sure, has a solution for this: unavailable_after.

Google has created a meta-tag named unavailable_after which is just for this specific need.

Here is an example code on how to use it (don’t forget to add this code between the meta-tags of that specific page):

<META NAME="GOOGLEBOT" CONTENT="unavailable_after: 01-Jan-2008 12:00:00 EST">

That’s all.
