FAQ

Outsourcing your social media management isn't an expense, it's a strategic investment that activates 5 measurable growth levers:

1. Algorithmic Expertise: Our teams monitor daily Instagram and TikTok updates to adapt formats in real-time.
2. Productivity Gain: You save approximately 20h/week of content production and management.
3. Studio Quality: Immediate access to rare skills (Dynamic Editing, Copywriting, Motion Design).
4. Proven Performance: Our strategies generate on average +40% engagement vs generalist internal management.
5. Operational Flexibility: Scale your needs without recruitment or training constraints.

At Gust, we are stop-scroll specialists.
Platform choice isn't random, it follows your demographic target and commercial objectives. Here's our 2025 audience mapping:


  • TikTok & Instagram (Reels): Essential for B2C and reaching 18-35 year-olds via visual virality and recommendation algorithms.

  • LinkedIn: The sovereign B2B channel. Targets decision-makers (high-income) with high average basket and long sales cycles.

  • Facebook: Still powerful for local audiences and 35-65 year-olds with confirmed purchasing power.

  • YouTube: World's 2nd largest video search engine. Ideal for tutorials, product demonstrations, and video SEO.

  • Pinterest: Visual discovery engine for inspiration (Decor, Fashion, Food, Weddings).



Our recommendation: Concentrate 80% of your efforts on the 2 platforms where your paying audience actually is.
Stop-Scroll content refers to a creative methodology designed to capture user attention in less than 0.8 seconds to interrupt scrolling behavior.

At Gust, our proprietary framework relies on 5 technical pillars:

1. The Visual Hook (0-3s): Using fast movements or pattern interrupts to ensure an initial retention rate >40%.
2. Native Format: Strict adherence to platform codes (9:16 Reels, trending audio, Safe Zones).
3. Emotional Storytelling: Triggering an immediate reaction (surprise, laughter, relatability).
4. Human Embodiment: Authentic faces generate 2x more engagement than graphic content.
5. Data-Driven Iteration: Analyzing drop-off curves to optimize every second.

This approach allows us to transform a simple impression into a qualified interaction.
Social Ads refers to targeted advertising on social networks. Unlike organic (free but slow), Social Ads is an immediate business accelerator.

It enables:

1. Laser-Precise Targeting: By age, interests, purchase behavior, or professional position (LinkedIn).
2. Retarget Your Visitors: Re-display your products to people who visited your site (Conversion rate x3).
3. Scale Sales: Once a profitable ad is identified (ROAS >3), increase budget to mathematically increase revenue.
4. Test Quickly: Launch multiple creatives in parallel with test budgets (<$100/day) to identify winners.
5. Measure ROI: Pixel tracking and Conversion API to calculate real acquisition cost.

It's the essential lever to move from awareness to measurable customer acquisition.
Platform choice depends on your primary conversion objective. Here's our 2025 decision matrix:

1. Meta Ads (Facebook/Instagram): Most versatile. Ideal for E-commerce and B2C Lead Gen. Average CPC: $0.50 to $2. Ultra-mature interest targeting.
2. LinkedIn Ads: The B2B sniper. High CPC (>$5) but unbeatable lead quality for targeting decision-makers (CEOs, HR Directors).
3. TikTok Ads: Volume at low cost. Perfect for brand awareness and impulse buying among Gen Z / Millennials. Very competitive CPM.
4. YouTube Ads: Web's TV format. Ideal for explaining complex products or long-form storytelling (>30s).

Our recommendation: Never launch more than 2 channels simultaneously in startup phase (Budget <$5k/month). Master one platform first before diversifying.
ROI measurement at Gust isn't limited to likes. We follow a precise performance equation based on 3 KPI levels:

For Paid (Social Ads):

  • ROAS (Return on Ad Spend): We target x4 to x8 (€4 generated for €1 invested).

  • CPA (Cost per Acquisition): Precise tracking via Meta Pixel and Conversion API to optimize cost per lead.

  • LTV/CAC Ratio: We analyze if long-term customer value justifies acquisition cost (Target: >3).



For Organic:

  • Average engagement rate (Target: >3% on Instagram, >5% on TikTok).

  • Earned Media Value (EMV) of your free reach.

  • Website clicks and indirect conversions tracked via UTM.



Our monthly reports integrate these metrics via certified connectors for total transparency on profitability.
The optimal frequency to trigger algorithmic virality in 2025 is precise. Here's our 'Minimum Viable' grid validated on our client accounts:


  • TikTok & YouTube Shorts: 5 to 7 videos / week (Volume is the key to virality – each video is an algorithmic lottery).

  • Instagram Reels: 3 to 4 Reels / week (To maximize non-follower reach and suggestions).

  • Instagram Carousels: 2 to 3 posts / week (Excellent save rate, good for engagement).

  • LinkedIn: 2 to 3 expert posts / week (Tuesday and Thursday morning 8am-10am preferred for max visibility).

  • Instagram Stories: Daily (To maintain proximity and stay top of feed).



Caution: Regularity beats intensity. Better 3 excellent contents per week for 12 months than 10 contents for 1 month then silence (Algorithm penalizes irregularity).
Community Management isn't just moderation, it's your frontline customer service and sales on social networks.

An effective CM at Gust ensures 4 vital functions:

1. Responsiveness (Customer Service): Answer questions within 24h maximum to maximize satisfaction and algorithmic engagement.
2. Closing (Sales): Transform DM (Direct Message) questions into qualified business opportunities.
3. Brand Protection: Proactive moderation of toxic comments, spam, or fake reviews to preserve your e-reputation.
4. Animation & Engagement: Create conversations (questions, polls, UGC) to boost your account's algorithmic 'Relevance Score'.

An active community is an asset that reduces your advertising costs: it generates free word-of-mouth, spontaneously defends your brand, and improves your conversion rate through social proof.
