When I get married, I came to know my wife alter her dresses to one specific tailor in her parents area. That tailor was little far from my area then also even after she moved to area, she always go to him only. I drop her there always so I also started loving his service.
But one little problem was he was not on the main road of area. so was not able to get nice business. When I asked him, how people come to know you are giving this service? He had no answer. Whenever I visited him, I always feel he want more business. So I decided to up and run his business more nicely.
Firstly, I ask his firm name if any, he said my name is my firm only. I said ok. So I grabbed my phone, opened google map & locate his shop. Entered all required details which can grow his business like phone number & timings. I told him in few days you will start getting more contacts and work for sure. He smiled & we left.
Google approved after few days, I could see his place on map. After few months, we still go there to alter cloths. But the person who was returning cloths on the same day with alternation, start giving timings to come to take cloths like after two days, three days. 
On that day I realized this seems a magic of google map only. I do know he realized that or not. Today he has few more people to give services, his smiles, his behaviors everything is making me realize that to grow local business, we should use google maps and guides.
From that day I really start feeling proud & I get myself involved more and more into it. My motto of being local guide is to SAVE TIME & MONEY of people. I review most places so people can decide where to spend money. I locate missing places as well so people can get easy and fast access of those places, which simply saves their time.
