"When a post is doing well, and it gets a ton of 'likes' and comments, that's extremely valuable from an advertising perspective," says Tom Montgomery, co-owner of the San Francisco-based company.Chubbies sometimes gets thousands of "likes" and comments for a single picture. Photos, including those posted by customers, often show men in shorts in offbeat situations a¿¿ at weddings, diving off cliffs and posing with a stuffed brown bear. But it finds the other services valuable. Chubbies uses Twitter to carry on conversations with individual customers. Its Facebook posts include more detailed content with a longer shelf life than the more fleeting posts of Twitter and Instagram. FOCUS ON PHOTOS Pinterest is a growing resource for Cornerstone Shop & Gallery, a home furnishings and gift shop in Lake Geneva, Wis. The store's customers tend to be women and Pinterest is a good place to find them. Owner Karin Bennett posts hundreds of pictures from the store on Pinterest's "boards," or photo collections. Current boards include holiday decor and gift ideas. "You can get lost in the visuals for hours," Bennett says. But Bennett also uses Facebook because it attracts middle-age and older women. Besides photos of merchandise and news about promotions and events, she posts pictures of customers, who often share the photos on their own Facebook pages. This month, customers are posing in the store with Santa Claus. Bennett uses Twitter to tell customers and other businesses about store events. Instagram isn't yet a fit because its users tend to be younger. "But we are starting to get younger people in the store during the summer, so we kind of dabble in it," Bennett says. TOUCHING ALL BASES The social media strategy at Three Brothers Bakery of Houston includes all four services plus a blog on its website. There's so much to keep track of that the company hired a public relations consultant to manage it all. Co-owner Janice Jucker sends content and photos to staffers at Integrate Public Relations who write the blog, post photos on Pinterest, Facebook and Instagram and start conversations with customers on Twitter. The postings often draw people to the Three Brothers website.
