Facebook started beta testing an attribution solution for marketers to analyze the impact of their campaigns both on and off Facebook in March 2017. Last week, the company released Facebook Attribution out of beta to all advertisers. It also introduced a new “data-driven attribution model.” The free tool is powered by the Facebook Pixel and can report on campaigns across Facebook, Instagram, Audience Network and Messenger.. The reports are designed to show how Facebook ad campaigns are impacting actions throughout the customer journey and which channels are driving traffic, conversions and purchases.
