While most companies won’t tell you the exact science behind their search engines, Facebook has decided to take a different route.
As part of their recent push to be more transparent about how the site uses content from users across its platform, Facebook has released a short video explaining how its search results work.
How Facebook Search Works
According to the video, Facebook relies almost entirely on users’ activity on the platform to evaluate its search engines. Users’ activity outside of Facebook has no influence on the search results.
Specifically, Facebook ranks results based on recent activity on Facebook and the activity of the overall community related to that search.
The types of activity that can influence search results include:
- What your friends share with you
- Pages you follow
- Groups you’ve joined
- Events you’ve liked or followed
- Things you’ve interacted with in your News Feed
- Information you’ve listed on your profile
- Places where you’ve been tagged
- Previous searches you’ve done
Facebook’s search results also consider the overall activity it is seeing across Facebook, including how popular the search topic is and the medium of the content. For example, videos hosted on Facebook’s platform may be prioritized over links to blog posts that are hosted off-site.
