Meta launched three major new ad formats in Q1 2026: Immersive Reels Ads (full-screen vertical video with interactive overlays), AI Creative Hub (on-platform AI image and video generation), and Shop Ads 2.0 (native checkout without leaving the app). We tested all three across 500+ client campaigns. Here's the raw truth.
Immersive Reels Ads: High Engagement, Tricky Attribution
Immersive Reels Ads deliver 2.3x the engagement rate of standard feed placements. The interactive overlay — letting users swipe through product images or answer a quiz — drives dwell time up significantly. The catch: attribution is murkier, as Meta counts overlay interactions as conversions in some reporting views.
- Average engagement rate: 8.7% vs 3.8% for standard feed
- CPM premium: 35–50% higher than feed placements
- Best for: e-commerce, mobile apps, lead gen with visual products
- Watch out for: inflated conversion metrics in native reporting
“Immersive Reels are the most exciting new format we've tested in three years — but verify your attribution before scaling.”
— Karim Naguib, Media Buying Lead”
