The Text and Composition

Drop the asset into Canva or Photoshop. AI is terrible at placing text perfectly.

Keep text under 4 words. The thumbnail should create a 'curiosity gap' that makes the user click to find the answer.

Key takeaways

  • 1Use AI for the background and expressive faces, use humans for the text layout.
  • 2High contrast, high saturation, and extreme emotions drive clicks.
  • 3A/B test your AI thumbnails using YouTube's native testing feature.
