Facebook is finally giving advertisers 2 things they've been asking after for ages

Secondly, Facebook has announced a partnership with analytics firm Moat, which will act as an independent third-party to provide marketers with data on how their Facebook video ads are performing.
Moat will verify video ad views, as well as the length of time users spend watching Facebook video ads.
The partnership will begin with video ad measurement, but in the coming months the two companies plan to extend the deal to include all other news feed ads and Instagram ads. The announcement comes three months after Twitter announced it had enlisted Moat to measure video viewability on its platform.
