In a predicable yet still interesting move, Facebook has started testing a new feature on its news feed ads and page posts: a native “Buy” button designed for enabling one-click purchase without leaving the site. Diving deeper into e-commerce integration, the social giant is working with some select small business partners in the US to try out this new direct purchase function, aiming for further roll-out if the trial proves successful. With Facebook taking the lead, we expect to see more and more digital platforms joining in the trend of build-in e-commerce infrastructure.
