Facebook’s “People You May Know” feature suggests potential connections to users, even in the absence of shared friends. These recommendations are based on a variety of factors including, but not limited to, shared networks, workplaces, schools, contact information uploaded to the platform, and activity on the site. For example, an individual might be suggested to a user because they both belong to the same professional association, even if they have no friends in common on Facebook.
The absence of mutual friends in suggested connections can broaden social circles and facilitate networking opportunities beyond existing contacts. This functionality enables users to discover individuals with similar professional interests, educational backgrounds, or geographical locations, which might otherwise remain unknown. The feature has evolved over time, with adjustments made to the algorithm based on user feedback and privacy considerations.
