YouTube Ad Best Practices (2026)
Shorts Golden Duration
10-30 seconds is the sweet spot for YouTube Shorts ads. Action-oriented content in this range drives the highest conversion rates.
Vertical Beats Square
9:16 vertical video outperforms 1:1 square in the Shorts Feed. Always prioritize vertical for Shorts ad placements.
Sound Boosts Conversions
Shorts ads with music or voiceover see 20%+ higher conversion rates. Audio is a key differentiator on YouTube.
Native Feel Priority
Ads should blend into the Shorts Feed. Overly polished or obviously promotional content gets skipped faster.
