The company page on Facebook of Junnoon, an Indian restaurant in Palo Alto, Calif., includes basic information such as address, hours, prices, photos and coming events, as well as reviews from local newspapers and Zagat. By opting to become a “fan” on the company page, instead of just a Facebook friend, people can make reservations directly from the page and post ratings and reviews. Although company pages are free, Facebook hopes companies that use them also will buy ad space through its new Social Ads program. Ads can be used to target Indian food enthusiasts in the local area. Companies can either pay per click or per page view. The minimum cost is $5 per day.
