No matter which platform you're using, your first 3 seconds must grab attention. Try these hooks:
  • Ask an interesting question
  • Share a surprising fact
  • Show an unexpected image
  • Make a bold statement
  • Start with the end result

2. The 80/20 Rule

  • 80% of your message should be in the first 20% of your video
  • Don't save the best for last - show it early!

3. The Loop Factor

Make your videos rewatchable by:
  • Adding subtle details viewers might miss first time
  • Creating satisfying transitions
  • Using cliffhangers that connect to the start
  • Including text that's worth reading twice

How to Test Your Video Length

Step 1: Create Three Versions

  • Super short (7-15 seconds)
  • Medium (15-30 seconds)
  • Longer (45-60 seconds)

Step 2: Post at Similar Times

  • Post on the same days of the week
  • Keep other variables constant

Step 3: Track These Metrics

  • Watch time
  • Engagement rate
  • Number of replays
  • Share count
  • Comment quality

2. Slow Starts

  • Cut the long intros
  • Get to the point quickly
  • Show your best stuff first

3. Not Optimizing for Each Platform

  • Don't post the same length everywhere
  • Adjust your style for each platform
  • Use platform-specific features
