Every social media platform — Facebook, Instagram, YouTube, TikTok — uses an algorithm to decide what content appears in your feed. These algorithms analyze engagement signals like likes, comments, shares, and watch time to determine what's relevant and interesting to each user.
For example, Facebook's algorithm prioritizes posts with high engagement, while Instagram pushes Reels that get quick interaction to the Explore page. These algorithms change frequently, so what worked last year might not work today. The key for marketers: create content that drives genuine engagement, because that's what every algorithm rewards. If Reels are getting 3x the reach of static posts, pivot to Reels.
