Hello! I have a domain example.com and have several locations with shops. So in my opinion it would be best to register all locations in Google places with the subdirectories like: www.example.com/city-1/ www.example.com/city-2/ www.example.com/city-3/ and so on.
My problem is that this is exactly what I tried, but even I verified the locations by telephone, all of them rank very poor in Google places (on page 6 and beyond), while the subdirectory itself ranks without problem (for example on "keyword city-1" on position 8 - but after the places-results).
Could this be a problem of using subdirectories in Google places? Other domains I use which I registered the main-domain www.example2.com on Google places rank fine in Google AND Google places.
Yes that is a problem, based on the research I have done, via news articles and Youtube videos, Google does not like duplicate sites registered. An another thing is customer reviews from sites like, Yelp, Insiderpages and merchant circle will add to your page ratings.
