In the first day of release, Twitter lead the traffic drivers to the Jimmy Eat World site, with more than 22% of all traffic coming straight outta Twitterland. Twitter was third as a driver of revenue, though, driving just over 20% of all sales. Still, with the large number of people reached, and email a smaller percentage of total sales in this campaign than we see on average, it’s very reasonable to conclude that Twitter was a meaningful driver of incremental revenue.
