Last November, Google has started testing a new design for its search, highlighting relevant verticals in a left-hand side column (à-la Bing). It seems Google has updated its design in the recent days. At first glance, this update features some aesthetic changes towards a more bland design(typical of Google products). More interesting: the most relevant search tools for the given query are now displayed just below the list of verticals.
For a shopping-oriented query, the “shopping” link, redirecting to Product Search, is displayed along with the “fewer shopping sites” / “more shopping sites” search options. Nice.
