Google has given the “people also search for” query refinement box a brand new look and feel. The company has been testing numerous designs of the feature for quite a long time now, and even includes dynamic loading versions.
A box has been placed around an organic result with “people also searched for” suggestions below, and separated by a line. The suggestions will either load on delay or if a user clicks on a result and clicks back to the search results.
This is a feature that Google has tested since last November.
Despite it being supposedly rolled out fully, I was unable to get the same results when I tried it.
