## The Power of the Algorithmic Interest Graph
Social platforms have transitioned from friend networks to interest discovery engines. Even a brand account with zero initial followers can reach hundreds of thousands of high-intent buyers if the first 3 seconds hold attention.
3 Rules for 80%+ Video Retention:
1. **Never introduce yourself**: Jump immediately into the core problem or insight within 1.5 seconds.
2. **Pacing transitions every 2.5 seconds**: Use dynamic B-roll cuts, kinetic typography overlays, and sound design accents.
3. **In-video debate triggers**: Frame polarizing questions that encourage viewers to leave comments, which signals algorithmic quality.
