Joy Hawkins noticed that her local listing now has stars to convey her local businesses reviews within the Google My Business center.
But previously, the stars only showed for those who used AdWords Express. Now Joy says they show for anyone who uses location extensions.

Great news for small businesses! You can now get gold stars in Google AdWords via Location Extensions that show your Google Plus reviews. No more need to use AdWords Express!
The picture above is an example of stars showing on a local ad with location extensions.
