That’s the subject of a new study by ad network Chitika, who analyzed the browsing habits of 33 million unique users over the course of September.
According to their findings, Facebook provides the most loyal visitors, with 20% of those that originate from the social network in turn visiting the site they landed upon four or more times in a week. Among other social media sites, Digg traffic produced loyal users 16% of the time, while Twitter traffic was only good for 11% loyalty.
In the realm of search engines, Yahoo () provides the most loyal visitors at 15%, followed by Google () and Bing () with around 12% each.
The finding that social sites provide stickier traffic isn’t surprising, but what implications do the loyalty rankings for Facebook (), Digg (), and Twitter () have, if any? Perhaps that in the long-run, encouraging your visitors to share on Facebook might have the most value, even if it doesn’t provide the most short-term traffic.
That said, it’s easy enough to provide sharing options for a multitude of social media sites (case in point, this post!), so you can probably file this under the “nice to know” category of statistics and use your own analytics to gauge what is and isn’t working.
