According to an unofficial source for Google news and tips at Googlesystem.blogspot.com, Google Maps is planning a launch of a new interface for Google Maps. As seen below, the current interface shows the search results in the sidebar to the left of the map:
The new update removes the sidebar to expand the map having the results display as an overlay within the map. An added feature will allow the viewer to restrict local search results to places recommended by top reviewers or from your Google+ circles.
The release date on the updated map and features are unknown at this time. If you haven’t set up a Google+ account for your business, there’s no time like the present. I’m noticing a trend here with Google integrating all of their products around their Google+ network. Get your business page set up and established so future changes from Google won’t negatively impact traffic from their channel!
