Retailers are exploring a new frontier in social commerce as they go beyond simply offering Facebook pages and Twitter profiles for their customers to follow.

Fueling this trend is web retailers’ quick adoption of social sign-on, which allows consumers to log in to their Facebook account instead of registering on an e-commerce site. Social sign-on gives retailers access to rich profile information for targeting customers.

＂Bringing Facebook profile data into retail sites makes sense because it influences consumers,＂ said Jeffrey Grau, e-marketer principal analyst and author of the new report ＂Social Commerce: Personalized and Collaborative(合作的) Shopping Experiences＂. ＂In contrast, many consumers on Facebook are mainly socializing with friends and further removed from making purchase decisions.＂

Over half of online retailers who responded to an August 2016 survey by Gigya, a provider of social sign-on applications, had either implemented the feature or planned to add it in the near future.

The Gigya study highlighted the benefits that online retailers and media-entertainment publishers get from offering social sign-on. At the top of the list were increased reservation (84%) and richer profile information for targeting product recommendations, emails, promotions and coupons(优惠券)(80%).

＂Social networks like Facebook are a center of information about people’s likes and interests,＂said Grau.＂When consumers give a retailer permission to access their personal data on Facebook, the retailers see not only what those people have written in their profiles but also the content they have ‘liked’ on other sites.＂

A separate study outlined just some of the data available from various sites — not counting other information, like which products, news articles and content on third-party sites they link to in status updates.

Retailers must also be careful about delivering personalized recommendations and targeted ads. These could make consumers feel that their online privacy is being invaded and create a backlash, which is already a perennial(反复的) problem for social networks like Facebook.
