Social Fresh partner, Argyle Social, spoke at Social Fresh EAST about the merge of social media and ecommerce. They have put in a great amount of research, on how the top ecommerce websites are using social media -successfully and otherwise.

We have featured Argyle research in the past on the best time to post to Facebook.
