“I would love to say that I just had a really good idea and strategy, but Twitter has been pretty essential to my success,” he said. He has quit his day job as a carpenter to keep up with the demand.
Much has been made of how big companies like Dell, Starbucks and Comcast use Twitter to promote their products and answer customers’ questions. But today, small businesses outnumber the big ones on the free microblogging service, and in many ways, Twitter is an even more useful tool for them.
For many mom-and-pop shops with no ad budget, Twitter has become their sole means of marketing. It is far easier to set up and update a Twitter account than to maintain a Web page. And because small-business owners tend to work at the cash register, not in a cubicle in the marketing department, Twitter’s intimacy suits them well.
“We think of these social media tools as being in the realm of the sophisticated, multiplatform marketers like Coca-Cola and McDonald’s, but a lot of these supersmall businesses are gravitating toward them because they are accessible, free and very simple,” said Greg Sterling, an analyst who studies the Internet’s influence on shopping and local businesses.
Small businesses typically get more than half of their customers through word of mouth, he said, and Twitter is the digital manifestation of that. Twitter users broadcast messages of up to 140 characters in length, and the culture of the service encourages people to spread news to friends in their own network.
Umi, a sushi restaurant in San Francisco, sometimes gets five new customers a night who learned about it on Twitter, said Shamus Booth, a co-owner.
He twitters about the fresh fish of the night — “The O-Toro (bluefin tuna belly) tonight is some of the most rich and buttery tuna I’ve had,” he recently wrote — and offers free seaweed salads to people who mention Twitter.
Twitter is not just for businesses that want to lure customers with mouth-watering descriptions of food. For Cynthia Sutton-Stolle, the co-owner of Silver Barn Antiques in tiny Columbus, Tex., Twitter has been a way to find both suppliers and customers nationwide.
Since she joined Twitter in February, she has connected with people making lamps and candles that she subsequently ordered for her shop and has sold a few thousand dollars of merchandise to people outside Columbus, including to a woman in New Jersey shopping for graduation gifts.
“We don’t even have our Web site done, and we weren’t even trying to start an e-commerce business,” Ms. Sutton-Stolle said. “Twitter has been a real valuable tool because it’s made us national instead of a little-bitty store in a little-bitty town.”
Scott Seaman of Blowing Rock, N.C., also uses Twitter to expand his customer base beyond his town of about 1,500 residents. Mr. Seaman is a partner at Christopher’s Wine and Cheese shop and owns a bed and breakfast in town. He sets up searches on TweetDeck, a Web application that helps people manage their Twitter messages, to start conversations with people talking about his town or the mountain nearby. One person he met on Twitter booked a room at his inn, and a woman in Dallas ordered sake from his shop.
The extra traffic has come despite his rarely pitching his own businesses on Twitter. “To me, that’s a turn-off,” he said. Instead of marketing to customers, small-business owners should use the same persona they have offline, he advised. “Be the small shopkeeper down the street that everyone knows by name.”
Chris Mann, the owner of Woodhouse Day Spa in Cincinnati, twitters about discounts for massages and manicures every Tuesday. Twitter beats e-mail promotions because he can send tweets from his phone in a meeting and “every single business sends out an e-mail,” he said.
Even if a shop’s customers are not on Twitter, the service can be useful for entrepreneurs, said Becky McCray, who runs a liquor store and cattle ranch in Oklahoma and publishes a blog called Small Biz Survival.
In towns like hers, with only 5,000 people, small-business owners can feel isolated, she said. But on Twitter, she has learned business tax tips from an accountant, marketing tips from a consultant in Tennessee and start-up tips from the founder of several tech companies.
Anamitra Banerji, who manages commercial products at Twitter, said that when he joined the company from Yahoo in March, “I thought this was a place where large businesses were. What I’m finding more and more, to my surprise every single day, is business of all kinds.”
Twitter, which does not yet make money, is now concentrating on teaching businesses how they can join and use it, Mr. Banerji said, and the company plans to publish case studies. He is also developing products that Twitter can sell to businesses of all sizes this year, including features to verify businesses’ accounts and analyze traffic to their Twitter profiles.
According to Mr. Banerji, small-business owners like Twitter because they can talk directly to customers in a way that they were able to do only in person before. “We’re finding the emotional distance between businesses and their customers is shortening quite a bit,” he said.

As with blogs and forums, Twitter is a great place to ask questions you’re too lazy to find the answers for yourself. And the service is absolutely perfect for asking favors (“Can anyone help me move on Friday?”), gathering opinions (“Do organic bananas taste better?”), or getting advice (“How much RAM should I get for my new MacBook?”) Twitter takes a problem you can solve by spending 5 minutes at a 
Other than entertaining strangers, this is my favorite use of Twitter. One message at a time, knowing who has a cold or who got in a fender bender is dull. But in aggregate, skimming your Twitter feed gives you a sixth sense about what your social circle is up to, what moods they’re in, whether they’re free for a drink that night and whether you’d better offer to pay. Unlike the more intense location-based services, Twitter still has a built-in casualness: You’re not necessarily asking people to meet you right here right now, you’re just asking if anyone’s free for lunch.
