If you have a Facebook Page for your business, you should strongly consider running a social, interactive promotion on your Page. According to Jupiter Research: 80% of all internet users have entered at least one sweepstakes or contest within the past year, and 50% enter them at least once a month. And, companies that run contests or sweepstakes have twice as many fans on their sponsored social network pages as those who don’t. Pretty powerful metrics for any type of business. Running a social promotion on Facebook is easier than you might think.
