Carousel vs Video vs Image — The IVF Meta Ad Format Split (2026 Data)

The current IVF format mix (market reality)

Across ~600 IVF ads catalogued in Prism Spy:

• Carousel: ~41% of all active IVF Meta ads
• Video: ~32%
• Image: ~22%
• Reels: ~5%

This represents what brands actually run — not what works best. The performance data tells a different story.

Per-format performance benchmarks

Carousel — the workhorse

Dominant format for cost-explainer ads + process walkthroughs. CPL: median ₹1,580; top quartile ₹820. Hold Rate: ~52% (Hold Rate for Carousel = % completing all slides). Patient mental model: "I want to understand the steps." Best for awareness + research stages.

Video — the conversion engine

When video hits top-quartile Hold Rate (≥55%), it outperforms Carousel on consult attribution by 1.8×. CPL: median ₹1,420; top quartile ₹720. Hold Rate: ~48% (variance higher). Patient mental model: "I want to see + hear the doctor." Best for decision stage + trust building.

Image — the volume player

Cheapest per impression, lowest conversion. CPL: median ₹2,100; top quartile ₹1,180. Effective Hold Rate: not measured directly (static). Patient mental model: glanceable awareness. Best for top-of-funnel awareness + brand recall.

Reels — the rising format

Small share but fastest-growing. CPL: highly variable (median ₹1,850; top quartile ₹680). Best Reels can outperform Video on CPL by 30-50% when content fits format. Patient mental model: discovery + casual browsing. Best for awareness + younger demographic capture.

Format-stage matching

The optimal format depends on patient research stage (per ICG's IVF research cycle):

The recommended format split

For an IVF clinic Meta budget allocated to maximise consult attribution:

• Carousel: 35% (process + cost explainer dominance)
• Video: 35% (doctor authority + decision-stage conversion)
• Image: 15% (awareness + simple CTA reminders)
• Reels: 15% (discovery + younger demographic capture, growing)

The market currently runs Carousel at 41% and Reels at 5%. Brands shifting to 35/35/15/15 see 18-25% Hold Rate improvement on average.

Per-format fatigue

• Image — fastest fatigue (12-18 days peak). Refresh frequently.
• Carousel — moderate (18-24 days). Refresh slide order or key visual to extend.
• Video — slower fatigue (22-32 days). Hook + thumbnail refresh can extend further.
• Reels — surprisingly long-lived (25-40 days) when hook is strong because algorithm feeds to new audiences.

The cross-format remarketing flow

Best-practice IVF Meta campaign uses formats sequentially:

1. Reel awareness → patient first sees brand on Reels feed
2. Image retargeting → "research IVF" landing page visited; Image ad reminds
3. Carousel research → patient clicks; Carousel walks through process + cost
4. Video conversion → doctor-led video for trust + consult CTA
5. WhatsApp BAPI nurture → patient nurtured through 4-6 week cycle
