Facebook is making it easier to show that an ad displayed on the social network led to a sale.
This new advertise is called conversion tracking.
After years of testing the idea, Facebook rolled it out to all advertisers.
Facebook creates a customized conversion pixel that advertisers place on a page.
This lets Facebook link sales to ad campaigns, showing in aggregate which ads generated the most response.
Google has long had similar features, along with Google Analytics, a dashboard for doing deep analysis of users’ actions on a website.
But Facebook has rolled out something far more powerful that can consistently track users across mobile devices and desktop websites.
Facebook experimented with conversion tracking in 2010, abandoning it and then rolling it back as a service restricted to its biggest advertisers.
