Facebook said it had underreported the number of views on iPhone of content published by some publishers using its Instant Articles platform between 20th September and 30th November.Publishers often make money through ads on their posts.
Facebook said on Friday that a recent update to one of its metrics had led to the issue and affected publishers alot using one of its legacy platforms.They said that traffic numbers for iPad and Android devices were not affected.
The company apologized in September for this error in the way it measured a key measure of video viewership that significantly amplified users ’viewing times on its platform.
Facebook said, “The latest issue has been fixed and updated estimates will be provided”.
Facebook also said it was updating the way it calculates potential audience size for ads as a way to give advertisers a better view of the number of people they can expect to reach there.
