Finding someone on Facebook is a very common problem for a lot of internet users, especially if one doesn’t have an account. Another issue is privacy concerns: not all searches should be tracked by Facebook and visible in your search suggestions due to privacy reasons. Here are some tips to safely find person on Facebook:
Use input above and directly search by one’s Name or Surname.
Try to extend search query by relevant keywords, which person could use in the Facebook profile section description, for example, education places, current city or favourites.
Check up Images tab for a quick preview of the possible matches.
Searching for mutual friends or colleagues is one of the best alternatives: follow the above mentioned steps, but for the former co-workers and school alumni.
