Optimize your business’s title – Your title in Google Places should be your business name, and possibly include some reference of your location. For instance, if you own a franchised business, including a location keyword is important to distinguish yourself against other area franchisees.
Include keywords in your Places page description – Write a brief and concise description of your business, and be sure to include a keyword or two from the last step (don't go overboard adding keywords, though.)
Choose a few appropriate categories – Choosing the right categories is important, and you can include up to five – but only include categories that are actually relevant to your business.
Make your Places page as complete as possible – It’s generally thought that more complete Places pages have an edge over less complete pages in the eyes of the search engines. Photos, videos, links to your social media profiles, hours and additional information can help to make your Places page more engaging and appealing to users, too
