Google+ shares are more valuable to merchants than referrals from Twitter or Facebook, according to an analysis of $5 million worth of online purchases that came through the social commerce platform Addshoppers.com.
While Facebook claims the highest percentage of social revenue overall (38.76 percent), a referral from Google+ is worth an average of $10.78, compared to a Facebook referral at $2.35 and a Twitter referral at $1.62. Email shares were the most valuable at $17.93. Google+ users are most likely to share electronics, the researchers found.
The average order values, however, were highest on Tumblr, where popular categories include apparel and health. This infographic compares sharing statistics for Pinterest, StumbleUpon, Polyvore, and other popular platforms as well.
