Earlier this week a webmaster using Google Spain discovered, what is thought to be either a Google Test or Bug, where the descriptions that are usually placed underneath the link on search results were removed; perhaps Google is testing how searchers will react to seeing search results, absent a description, or perhaps it was just a tiny mistake that was spotted by a few webmasters, we are not sure yet!
During this test/bug period, when you conducted a search, all you saw were clickable links to websites; usually you see a small summary of a line or two describing what the web page you’re about to click on is about.

So the question still stands: is this a test, or a bug? If it is a test will it stick? Who knows! We will keep you updated!
