A social media algorithm is the system a platform uses to decide which content to show each user, and in what order. Rather than displaying posts chronologically, platforms like Instagram, TikTok, and LinkedIn analyse signals - engagement rate, watch time, relationship strength, recency - to surface content each individual is most likely to interact with.
For creators and brands, understanding the algorithm matters because it determines organic reach. Posting at optimal times, encouraging saves and shares (which signal strong engagement), and maintaining a consistent posting cadence are all ways to work with the algorithm rather than against it.
