The US Media Rating Council (MRC) has warned Facebook it could lose its accreditation since it has failed to address advertisers concerns as there are "deficiencies in how its reports on the effectiveness of advertising on its products, especially video ads.
If Facebook loses this "key seal of approval that gives companies confidence they are getting what they pay for when it comes to advertising with the social networking giant", it would be troublesome for the company which collected more than $17 billion in ad revenue in the first quarter of 2020.
"The Committee felt strongly that the lack of response and detailed action plans by Facebook within 60 days would lead them to take negative action," according to a MRC letter to facebook.
"This feedback should be considered a strong message to Facebook,' the letter read.
The ad measurement watchdog has warned Facebook that it could be denied accreditation based on how it reports on the effectiveness of advertising on its products, specifically its video ads.
A Facebook spokesperson said: "These exchanges are part of the audit process. We will continue working with MRC on accreditation, as we have since 2016".
The MRC "is looking for a proper accounting for video in a compliant manner," the letter read.
Accreditation from the US agency is a signal to advertisers of its trustworthiness.
