Facebook’s search suggestions are determined by a few key factors. When you start typing a name, page, group, or other search term into the Facebook search bar, their algorithms look at several things to generate relevant suggestions.
Your own previous searches
One of the main factors is your own previous searches. Facebook’s algorithms remember the people, pages, groups, locations, hashtags etc. that you have searched for in the past. As you start typing a new search, it will suggest terms you’ve searched before that match.
So if you’ve searched for “John Smith” in the past, when you start typing “joh”, Facebook may suggest “John Smith” again because it knows it’s relevant to you specifically based on your search history.
Trending searches
Facebook also looks at recent popular or trending searches to provide suggestions. If a certain term is being searched for frequently across Facebook, it will likely show up in the suggestions for many users even if they haven’t searched for it before.
For example, if #WorldCup is a trending hashtag, “WorldCup” may show up in search suggestions for many users when they start typing even vaguely relevant terms like “soccer” or “football”.
Your friends and connections
Facebook’s algorithms also factor in your friends, followers, groups and pages you’ve liked etc. If you start typing a name, it will suggest friends of friends or people linked to your connections in some way.
So if your friend Jane Smith recently got married and changed her name to Jane Thompson, “Jane Thompson” may show up as a suggestion even if you haven’t searched for her before, because Facebook knows she’s now connected to you somehow.
Demographics
Demographic factors like your age, location, gender, interests etc. also influence search suggestions. Facebook may tailor suggestions based on what is popular among people with similar demographics.
For instance, if you are a 28 year old female living in New York City who has liked Taylor Swift and Lady Gaga pages, you may see more suggestions for other pop singers when searching compared to a 45 year old male liking sports teams.
Pages and content you’ve interacted with
Facebook also looks at the pages, profiles, groups and posts you’ve liked, commented on, and otherwise interacted with. Terms and names related to that content you’ve engaged with before will likely show up as suggestions.
So if you’ve liked or commented on your favorite band’s page in the past, their name may autocomplete when you start typing even if you haven’t explicitly searched for them previously.
Context of what you’re typing
The context of what you are currently typing also influences the search suggestions. Facebook’s algorithms try to predict relevant people, places, or topics related to the words you’ve started typing so far.
If you’ve typed “My friends John and”, the suggestions may include friends of yours named John for you to select from, since that matches the context.
Privacy settings
Your own privacy settings as well as those of your friends and connections impact what shows up as a suggestion. If you or a friend have restricted profile visibility, those names may not populate for other users.
For example, if you have a friend named Emily Smith but Emily’s profile is set to private, “Emily Smith” may not show up in your searches or your other friends’ searches for Emily since her profile is not visible to them.
Pages you’ve hidden or reported
Pages, groups or people you’ve purposefully hidden or reported will not show up as suggestions. So if you hid your ex’s profile from your view, their name will not autocomplete even if you have mutual friends.
This helps prevent you from seeing names and terms you don’t want to surface in your search bar.
Advertisers
Facebook search suggestions are also influenced by advertisers who pay for better placement. Pages and terms that are sponsored may show up higher in search even if you haven’t searched for them before.
So a brand like Nike may appear as a suggestion as you type even if you haven’t interacted with their page previously, because they paid for the visibility.
Conclusion
In summary, Facebook uses a complex, personalized algorithm to generate relevant search suggestions based on factors like your previous activity, connections, demographics, context, privacy settings, and sponsored results. The autocomplete is tailored to each user to surface the most useful people, pages, groups, events and keywords as you type your search terms.
