FAQ

UGC (User Generated Content) refers to any authentic content (video, photo, review) created by real users or specialized creators to present a product naturally.

Why is it the #1 format in 2025?
Brands use it massively because it combines 3 decisive marketing forces:

1. Absolute Trust: 79% of consumers state that UGC directly influences their purchasing decisions (Source: Stackla).
2. Advertising Impact: UGC is perceived as 9.8x more impactful than classic influencer content because it is deemed more sincere.
3. Media Performance: In Social Ads, it generates 4x higher CTRs (click-through rates) and reduces acquisition costs (CPA).

It is the essential lever for e-commerce and reassurance (Social Proof).
These 3 formats meet complementary objectives in the marketing funnel:

1. Brand Content (Studio)
Objective: Brand Image & Premiumization
Production: Pro teams, polished aesthetic
Limit: Often perceived as 'too commercial'

2. Influencer Marketing
Objective: Awareness & Endorsement (Social Proof)
Lever: The creator's audience and community
Cost: High (media fee included)

3. UGC (User Generated Content)
Objective: Conversion & Authenticity
Lever: Realism and identification ('anonymous' faces)
Strength: The best-performing format for Social Ads (Meta/TikTok).
Our 'Data-Match UGC' casting methodology relies on 6 demanding criteria:

1. Product Affinity: The creator must match your target (age, lifestyle) for total credibility.
2. Technical Quality: Lighting, stability, sound. UGC must be authentic BUT not amateur.
3. Narrative Capacity (Hook): Talent to stop the scroll in 0.8 seconds (Stop-Scroll effect).
4. Acting Skills: Fluid diction and absolute naturalness to avoid the 'infomercial' tone.
5. Reliability: History of on-time delivery and creative brief compliance.
6. Diversity: Inclusive panel to test multiple customer avatars.

Out of 400,000 profiles analyzed, we retain only the top 1% of performing creators.
We produce the 6 'Winner Creative' formats essential for performing on TikTok and Meta:

1. Testimonial: The creator shares their authentic experience (before/after, benefits). It is the king format for trust and conversion.
2. Unboxing & Reaction: Sensory product discovery (ASMR, packaging). Perfect for e-commerce and the 'novelty' effect.
3. Tutorial / Demo: Educational 'How-to' showing concrete usage. Ideal for complex products, tech, or cosmetics.
4. POV (Point of View): Product staging in a real daily life context (Lifestyle) to encourage projection.
5. Comparison: Your product vs competitor to visually argue your superiority.
6. Haul: Dynamic presentation of several products from the same collection (Fashion/Beauty).
2024 performance data is unequivocal. By integrating UGC into your Social Ads campaigns, you obtain:

1. More clicks (CTR)
• Native format generates a 4x higher click-through rate than a classic banner.

2. More conversions
• UGC ads record a +43% higher conversion rate (Source: TikTok Business).

3. Lower costs (CPA)
• Cost per acquisition drops by -37% on average thanks to better Platform Quality Score.

4. Better retention
• Watch time is +20% higher because content looks like a friend's, not a brand's.
