Reporting for a multi-device world

Facebook has introduced cross-device reporting for its ads, allowing advertisers to track how users interact with ads across multiple devices, such as mobile phones, tablets, and desktop computers, before making a purchase.
This new feature addresses the common scenario where users see an ad on one device (e.g., mobile) but convert on another (e.g., desktop).
The report uses data from the Facebook Conversion Pixel and SDK, providing insights into the role of mobile ads in driving conversions.
Early testers, like One Kings Lane and TellApart, have found it valuable for understanding cross-device behavior and justifying mobile ad investments.
Advertisers can access the report via Facebook Ad Reports by selecting Cross-Device columns.
