what are featured viewers on facebook

On Facebook, "Featured Viewers" are friends who have looked at your featured photos or stories. They are prominently displayed on your profile and are meant to showcase your most active and engaged followers, including friends, fans, and followers who regularly interact with your page or profile. The "Viewers" are the total number of friends and non-friends that have looked at your featured photo or story, while "Others" are people who have viewed your featured collection but are not your Facebook friends. The data of the viewers appears to be anonymous, and it is currently not possible to view a list of the friends who have looked at your featured story
