I had a shocking revelation the other day when I checked (by accident) our Google Places (Now Google+ for Business Local) listing. I added all of the cities we served such as Burke, Alexandria, Woodbridge, etc about 2 months ago. This is better from an SEO standpoint than just adding in your zip code such as 22015 (Burke) and hoping for the best. Well, much to my surprise (NOT) our new Google+ for Business Local listing has dropped all of these areas! I suggest that if you have or had a Google Places listing that you check it and make sure that all of the data is correct and not dropped or deleted. See my video below on what I found and how to correct your local areas.
