Hey...
Here i am mentioning some tips to promote local business......
1) If your has business related website, post it. otherwise post your business phone number and/or email.....
2). Start a Twitter account with your business name as the "username" and your first and last names as the "name".
3)Find Twitter users in your area. How do you do this? One way is by clicking on the "Find People" tab at the top of any Twitter page. Enter the name of your city or area in the "Who are you looking for" box. You should get a ton of responses with users in your area.. "follow" these people and a good number of them will follow you back.
4)Another way to find followers in your area is to click on the username of some of the people you follow and see if any of their "followers" also live in your area.
5)The best way to find potential customers in your area is to use the search bar in the middle of the Twitter page. You can enter your city name and click the search button.
6)Advertise your business! After you've acquired a few hundred or so followers (this should only take a few days) start sending tweets about your business. Offer specials and incentives. If you have a website - promote that. To keep track of how well Twitter is working for you, you may want to offer a special discount to any customer who found you on Twitter.
