The Video Crossposting feature lets you share your videos on all Pages that belong to the same Business Manager. A video uploaded on one Page can be crossposted to any of the other Pages that meet the requirements. You are also provided with video metrics (in Page Insights) across all Pages that used the same video – this feature works also for live videos and 360 videos.
This feature lets you avoid constantly sending and uploading videos to measure the effects on other target groups and Pages.
