Getting followers on Twitter can be hard. I don't think it's so much that locals aren't interested in your tweets as much as they just don't know about your account. We encourage teamwork between local businesses to build awareness of local twitter accounts. Cross promote by re-tweeting and tweeting at each other. But remember, your followers can't see a tweet you send to somebody if they don't follow that person as well. For example, if Butcher Shop (you) tweets "@Candystore hi" to Candy Store, and your follower Bob doesn't follow Candy Store, he won't see the post. To avoid this, don't lead the tweet with their tag. If you start the tweet with anything except for their twitter handle, all followers will see the tweet.
So, do this : "Hey @Candystore" or "Hello @Candystore"
Not this: "@candystore hey."
