Facebook is looking to offer advertisers more insight around its customer's shopping habits.  


The social network giant will apparently now let advertisers know where a promotion was first viewed and whether it led to a purchase by tracking users across their devices.  


In a blog on its website, Facebook explained that marketers will be able to see the number of users that clicked on an ad and what kind of device they used.  


Facebook already offers targeting, delivery and conversion measurement across devices. With the company's new cross-device report, Facebook said that advertisers will now able to view the devices on which people see ads and the devices on which conversions subsequently occur.  


"For instance, a marketer can view the number of customers that clicked an ad on an iPhone but then later converted on desktop," the company explained, "or the number of people that saw an ad on desktop but then converted on an Android tablet." 


Facebook claims that in early tests of the reports, marketers were able to better understand the role of mobile in their campaigns and explain the differences in reports by third-party analytics tools that do not account for cross device conversions.
