Facebook has just announced they’ll now automatically remove the third-party attribution from feed stories.
Previously when a Page used a third party to post a story (for example, Hootsuite), the story would say “-via Hootsuite”.
They’re removing that attribution from feed stories (both paid and organic) from Pages, starting today. Attribution will still show up on user stories.
This will happen automatically for posts made to Pages by apps. There is nothing you’ll need to do. Also, there will be no way to opt-out.
The functionality is not live yet but will tomorrow.
