Key factors include engagement (likes, shares, comments), recency, relevance to your interests, watch time (for videos), relationship to the poster, and post format. Algorithms reward content that keeps users on the platform. Posts that spark conversation or repeated views are favored. Paid promotions increase visibility through targeting options. User behavior—what you pause on, save, or report—also trains the algorithm.
Some platforms prioritize different content types; for example, Instagram favors Reels, while X (Twitter) promotes trending tweets. Creators must understand these metrics to improve reach. Ultimately, content visibility depends on how well it matches platform goals and user behavior.
