What changed: Added a format-by-objective table, linked Meta's ads guide, and added the creative brief and hook tools.
Video ads achieve 2x the click-through rate of static images on average. Carousel ads deliver 30% lower CPA for e-commerce product catalogs. The best format depends on your objective: video for awareness, carousel for sales, and lead form ads for lead generation.
Key Takeaways
No single best format — it depends on your objective. For awareness: short-form video (under 15s) dominates with 2x CTR and 50% lower CPM than static. For sales: carousel ads showcase multiple products with 30% lower CPA. For lead gen: native lead forms keep users on-platform and cut CPL by 20% vs landing pages. Reels placement adds 15-25% reach at lower CPMs.
Match the format to the job. Awareness wants 9:16 vertical video under 15 seconds for Reels and Stories plus 1:1 for Feed — video captures 5x more time-on-ad. Lead gen wants Instant Forms, which skip the page load entirely. E-commerce wants a catalog format that can show more than one product.
| Objective | Best format | Why it wins |
|---|---|---|
| Awareness | Vertical video under 15s | 2x CTR and roughly 50% lower CPM than static |
| Lead generation | Instant Form (native lead ad) | Cuts CPL about 20% — no page load, pre-filled fields |
| E-commerce sales | Carousel or Dynamic Product Ads | 30% lower CPA than single-image for catalogs |
| Consideration | Collection (video + product grid) | 2x engagement versus a standard link ad |
AutoAdy analyzes performance by format across your account, identifying which types drive the best cost per result for each objective. It detects creative fatigue by format — video fatigues 40% slower than static images.

FAQ
Not always. Video averages 2x CTR but requires more production. High-quality static with strong copy can outperform mediocre video. Some B2B audiences respond better to clean image ads.
Under 15 seconds for awareness and Reels/Stories. 15-30s for consideration. 30-60s for retargeting. The first 3 seconds determine if people watch — front-load your hook.
Instant Forms reduce CPL by 20% but landing page leads are 15-30% higher quality due to extra friction filtering casual clicks. Test both and compare downstream conversion rates.
