What is Social Media Algorithm?

Each platform has its own recommendation algorithm. TikTok's For You Page algorithm weighs watch time, rewatches, shares, and comments. YouTube's algorithm prioritizes click-through rate, average view duration, and session time. Instagram Reels uses similar signals plus follower engagement rate. Understanding these algorithms is critical for content strategy: creators optimize hook timing (first 1-3 seconds), video length, posting frequency, and engagement prompts based on algorithmic preferences. Key signals across all platforms include retention rate (what percentage of the video viewers watch) and engagement rate (likes, comments, shares relative to views). BlitzReels helps creators optimize for algorithms through caption timing, hook placement, and platform-specific export presets.
