Facebook has provided figures indicating that Likes and its social plugin drive website traffic and conversions.

According to the social giant, media sites integrated with Facebook see 300 percent traffic increases on average. The company shared this and some impressive stats with Search Engine Land that may inspire marketers to boost their Facebook marketing campaigns.

Overall, the Facebook figures suggest that the social shares and referrals within its network are major traffic drivers, and Facebook-integrated sites benefit from convertible visitors. For instance, 40 percent of Levi's traffic from all sources comes from Facebook (compared to just 1 percent derived from the social site prior to adding Facebook buttons).

Once Like-based visitors hit sites, they tend to spend more time (and money) with businesses. Search Engine Land relays that American Eagle added the Facebook button to each of its products, and Facebook-referred visitors spent 57 percent more money than other site visitors.

One way marketers might encourage social sharing after integrating their sites with Facebook is by delivering Like-able news content. As Brafton has reported, Facebook is becoming an increasingly important traffic driver to news content, and Facebook told Search Engine Land that ABCNews.com and The Washington Post doubled their Facebook traffic after adding Like buttons to their content.

In addition to binging traffic directly from Facebook, integrating sites with the social giant is now an important way to catch search clicks among Bing users. As Brafton has reported, Microsoft's search engine recently unveiled a “Friend Effect” search feature for Bing users, using Likes as ranking signals for searchers logged into the social giant's network.
