Last month (see The Importance of Sharing) a few online publishers announced that social-media sharing platforms have become bigger sources than Google for referral traffic — those site visitors who click on links rather than typing a site’s URL into a browser from memory. Web 2.0 and VC blogger Fred Wilson says he gets more traffic from Twitter than from Google. One PC Mag writer published server logs that indicate Digg drives much more traffic to their tech stories than Google. And Twitter itself gets more traffic from Facebook than from search (Compete data here).
So it’s no surprise that social-media optimization — including integrated buttons and widgets that make sharing easier — is a growth activity across the online publishing sector. Earlier this week Adweek reported on Time.com’s experience with Digg optimization. (Disclosure: I work for Digg.). Time replaced its generic “share” button with a widget that pulls together recent Time stories that have been Dugg, ranked in order of most to least Diggs.

According to Time.com’s general manager, John Cantarella, the integrated approach increased traffic from Digg to Time by 164%. Time stories now end up on Digg’s homepage more than 100 times a month, up from 55 before the widget integration. The article cites other publishers (such as Newsweek and Wired) taking the same approach, with similar results. Telegraph UK experienced an eleven-fold increase in traffic from Digg after deploying the widget.
Ben Straley, CEO of Meteor Solutions, piled on yesterday in his Mediapost column, Sharing Is the New Advertising. First he added a few more names to the list of publishers for whom “sharing sites” are rivaling or beating out search for referral traffic: “Etsy recently reported that Twitter is the third-highest source of traffic to their site, and according to a Hitwise study, PerezHilton receives more of his traffic from Facebook than any other source.”
Brands such as Microsoft and Alaska Airlines (both Meteor clients, apparently) are jumping in, too.
“After working with lots of companies to do this type of measurement and analysis, we’ve uncovered some surprising results: namely that sharing drives significantly more traffic than search in some cases. On average, we’ve found that between 15-20% of unique visitors to the sites we’re tracking come by way of shared links, and there is a consistent left in conversion rates among visitors from this source….”
In one case he references, “the visitors that came to the site via shared links were1.5x more likely to convert than visitors that came from other sources including search.” Impressive data.
