Key Takeaways
- Reels delivered 33 % lower CPM on average compared with Stories (Meta internal data, Q1 2025).
- Stories achieved 27 % higher click-through rate, driven by tappable CTA stickers.
- Conversion rates were statistically similar (±0.2 % difference across verticals), making cost-efficiency the tiebreaker.
When to Use Stories
Stories excel for limited-time offers, polls, and sequential narrative ads. Use them when you need daily reach and interactive elements like swipe-ups.
When to Use Reels
Reels can drive efficient awareness at scale thanks to algorithmic discovery. Short UGC-style creatives (under 30 seconds) perform best.
