Social Media Definition

Algorithm (Social Media)

The system each social platform uses to decide which content to show to which users.

Full definition

Social media algorithms are proprietary systems that determine what content appears in users' feeds and in what order — replacing strict chronological feeds. Each platform's algorithm weighs different signals: engagement rate, watch time, shares, saves, account relationship (frequency of interaction), content type preferences, and recency. Understanding the algorithm of each platform you use is essential for organic content strategy. General principles across platforms: high engagement signals increase reach, native content (posted directly, not linked from elsewhere) performs better, consistent posting rewards accounts with broader reach, and content that generates meaningful interactions (comments, shares) outperforms passive engagement (likes).

Real-world example

Instagram's algorithm shows a Reel to a small test audience first. If engagement is high (watch time, saves, shares), it progressively shows it to larger audiences — including non-followers via Explore.
