Helzberg announced the "love"
promotion on its Facebook page, Twitter feed and on select blogs, but the main drivers--word of mouth and search engine marketing--drove up conversion rates from an average.35% to 1.6%. The promotion
generated 3,100 new customers in less than three days, and 140,000 visitors to the Web site, up 87% compared with the prior year. The company said it couldn't keep up with fulfillment and asked
Rosetta to suspend the promotion after three days.
