15s-vs-30s-reels-which-wins-for-conversions

Quick take: Both formats work in the UAE — 15s for speed and product desire, 30s for story and objections. Here’s how to pick.

15s: when speed wins

• Great for launches, offers, and single-point messages.
• Front-loaded value; one macro hero; one CTA.
• Pairs well with performance campaigns and A/B hooks.

30s: when story wins

• Use for multi-benefit stories or higher-ticket items.
• Add proof beats (demo, testimonial, note pyramid).
• Keep one CTA; avoid drifting CTAs mid-reel.

Captions, pacing & specs

• AR/EN captions improve retention for both lengths.
• 9:16 master, optional 1:1/16:9; ad-manager-ready exports.
• Internal links: AI Promo Videos · AI Promo Hub

Next steps

Cut one 15s and one 30s version from the same footage, then test two hooks in a small spend. Keep the winner and iterate weekly.

FAQ

Which performs best? It depends on offer and audience; start with 15s for speed, keep a 30s variant for story.
