The âFor Youâ algorithm
The home feed and Exploreâs For You mode use a transparent weighted score. Signed-out viewers and viewers without saved likes, watch history, or follows get a fresh, popular mix with slight variation during each Explore visit. Personal signals shape recommendations as you watch, like, and follow.
Exploreâs Latest mode sorts published vertical videos newest first. For Youâs session variation is temporary and is not saved as a visitor profile.
Follows
Videos from creators you follow and featuring models you follow receive the strongest boost.
Your interests
Tags from videos you like count more than tags from videos you watch.
Freshness
New releases receive a temporary boost so the feed does not become static.
Quality
Views and likes help surface videos that viewers choose and enjoy, using a logarithmic scale so one viral upload cannot dominate.
Discovery
Previously watched videos are pushed down rather than removed, leaving room for new creators and topics.
Trending is separate: it contains only videos published within the last 14 days and ranks them by views. The recommendation score can evolve, but these signal categories remain the public contract.
