Key Takeaways

• Think vertical: full-screen grabs attention

• Tap-friendly CTAs boost engagement

• Lightweight assets ensure speedy loads

Desktop’s passé—over 90% of Facebook time is on mobile. Nail these three design tweaks to win on small screens.

1. Go Vertical or Go Home

• Why it works: Full-screen vertical videos and images stop the thumb scroll.

• How to do it: Create 9:16 assets and preview them in Facebook Stories and Reels placements. Use QuickAds.ai’s creative hub to auto-format your horizontal videos to vertical in seconds.

2. Optimize for the Thumb Zone

• Why it works: Buttons in the center-lower third are easy to tap—anywhere else frustrates users.

• How to do it: Position your CTA and key text centrally and avoid placing clickable areas in the screen corners. You can preview safe zones with QuickAds.ai’s ad simulator before you launch.

3. Keep File Sizes Tiny

• Why it works: Slow-loading ads lose 20% of viewers in the first two seconds.

• How to do it: Compress images and trim videos to under 10 MB. Leverage QuickAds.ai’s asset optimizer to automatically reduce file size without killing quality.
