Yelp.com is a website where customers can search for local businesses and leave reviews of their experiences, and it also offers a number of free tools for small business owners. If you haven’t already, check Yelp to see if your business is listed; if it isn’t, you can list it for free. If it is listed, claim your page to take advantage of all that Yelp.com offers small business owners: communicate with your customers by responding to their reviews, promote discounts and special events, check the amount of traffic your Yelp business page receives, recommend other businesses, and provide detailed information about your business–including your website address. With more than 26 million visitors in December 2009, Yelp.com is a great way to connect with local traffic.

Google’s Local Business Center offers small business owners the opportunity to customize their listing on Google and Google Maps, with options like adding pictures, coupons, business hours, and more. You can also see behind-the-scenes information to find out things like who’s searching for you and what search terms they’re using to find you. You can even see where driving directions requests originate, so you will know where your visitors are coming from and whether you’re targeting local traffic.

The social networking phenomenon Twitter is another way to stay connected with your local customers, and Twitter is beginning to cater to small business owners. It’s a quick and immediate way to communicate with customers, see what people are saying about your business, and build relationships with customers and other businesses. Put a Twitter badge on your website and begin following local individuals and businesses, and before you know it you’ll have followers of your own. One of the really cool things about Twitter is that your conversations with customers are publicly visible and searchable, meaning they often attract attention from other Twitterers in the same locale or with similar interests.

Facebook, which began as a social networking site exclusively for college students, has expanded dramatically and now offers great opportunities for small businesses. When you create a free business page on Facebook, anyone can become a fan of your page and suggest that others do the same. You can provide detailed information on your profile (including your website address), post business updates, make photo albums, and converse with your fans. Facebook users can search business pages by location, and many are thrilled when they can become fans of their favorite local businesses. And since their friends can see what businesses they’re fans of, your local exposure increases exponentially with every fan you acquire.

These are four great websites that offer free ways to connect with local customers. They will help you target local traffic, learn about your customers, and provide your small business with a strong local presence even on the global Internet.
