A while back I wrote about UCLA Happenings implementation of Facebook's Social Widgets using the 'Like' button, and how it can lead to higher click-through rates, traffic referrals and more engagement for websites. To quickly recap, "The 'Like' button lets a user share your content with friends on Facebook. When the user clicks the 'Like' button on your website, a story appears in the user's friends' News Feed with a link back to your website."
A recent article by CNN talks about the impact of the 'Like' button and the results are impressive: "ABC News reported a 190 percent increase; Gawker's traffic shot up by 200 percent; Sporting News said their site traffic was up by a shocking 500 percent; and NBA.com said that Facebook had become their second-largest referral source."
Since implementing in April of 2010, UCLA Happenings has also seen a large referral of traffic from Facebook. Facebook has become one of our top ten referral sites for traffic and continues to be an important factor in keeping users enagaged on the site.
