A social algorithm is the set of signals a platform uses to rank content in feeds, stories, search and recommendations.
Why it matters
Most of your reach is decided by it. Understanding what it rewards helps you make content people actually want to see, rather than chasing tricks.
Signals that usually matter
Early engagement, watch time and completion, saves and shares, replies and DMs, and how often a person interacts with your account. The common thread: posts that people stop for, finish and act on get shown to more people.
