Example Output

Analysis Summary for [VIDEO_TOPIC]

Color Palette: Recommend shifting from muted blues to high-contrast red/yellow based on top 10 competitors in [NICHE]. Red creates 18% higher CTR in educational content.

Text Optimization:

  • Current: White sans-serif at 12% of canvas → too small on mobile
  • Recommended: Bold sans-serif (Impact/Montserrat) at 18% of canvas with black outline
  • Placement: Rule-of-thirds lower-third to showcase face expression

Facial Expression and Engagement Signals:

  • Top performers use shocked/curious expressions (87% of top 100)
  • Current setup: serious/neutral → recommend slight surprise
  • Eye direction should guide viewer toward text overlay

A/B Test Plan (Weeks 1-4): Control: Current thumbnail. Variant A: Add red border and increase text size. Variant B: Replace background and adjust color. Track CTR, watch time, and first-30-second audience retention.

Predicted CTR Improvement: 12-18% if recommendations implemented (based on similar channels in [NICHE])
