How does Facebook know who I know

Facebook: Suggestions for friends - where do they come from and how do you deactivate them?

If you scroll through your Facebook feed, you will be shown not only posts and advertisements, but also friend suggestions from time to time. Among the “people you may know” there are often plausible suggestions, but sometimes also uncanny representatives who ask how Facebook comes up with this contact suggestion.

We explain to you how Facebook determines these friendship suggestions, how you can prevent individual suggestions or completely switch off the fact that Facebook contacts who are not yet friends are displayed to you. You will not only see the suggestions in your feed, but also on the overview page for your friends.

  • Be ahead of all Compare lists with friends that have already been added. If there is an overlap in friend lists, there is a high probability that other friends of the relevant contact will be shown. As a rule, it is stated with whom the unknown contact is friends. If the friend in question hides his friend list, the information is not displayed.
  • Also from the Information that you store in your profile, data are determined. Facebook prefers to show you profiles of people who went to the same school or university as you or who stated the same employer.
