Google has launched what they are calling place topics. Place topics use data based on reviews to provide concise information on what customers highlight about your business. In short, it summarizes the reviews left by your customers into tags.
Here is a screen shot of what it looks like in the top of the reviews section, this screen shot is from Joy Hawkins as she posted it in the Local Search Forums:
This can be used by potential customers, where they can see at a glance the main themes of your business. Since Place Topics are based on customer reviews, business owners don't need to manage this feature, it is all automated. Of course, if your place topics say something you do not like, that can be an issue.
All businesses with a "sufficient amount of quality reviews" can benefit from Place Topics, Google said. Finally if your business doesn't have Place Topics, Google can't create them on demand.
