Google is constantly playing around and testing user interfaces for their search results and other services. Just recently, we captured them testing black instead of blue links in the main search results. Now, we are seeing Google testing two different interfaces, one that has a much more spacious and wider search results page layout, and the other that brings back the card-based styled interface from 2013.
Earlier this month, Google began testing the wider interface, and then earlier last week, the testspiked, and more and more searchers saw it. We asked Google about it, but they would not confirm or deny if it was something they would launch. They basically told us they are always testing things.
The new wider interface brings more space for longer titles, longer descriptions for both the organic results and the AdWords ads. But again, it may just be a test, and although many are seeing it now, Google may not officially launch it.
