First of all, analyze the competititors’ citations and try to get the same ones as they have. To do this, enter the localized search query that you want to show up for. Upon entering the Google Places page of your competitors and scroll to the bottom of the profile to the more about this place section. Here you will see the citations that are helping your competitors rank number 1 for this local search query.
