YouSwim Rebuilding for Scale:
How We Engineered
+36% Growth in 2025

Rebuilt.
Refocused.
+36% Growth YTD.
When YouSwim joined Social Nucleus at the start of 2025, the brand had everything you could want creatively — a premium product, strong community, and global recognition.
What it didn’t yet have was a performance system to match.
Within months, we rebuilt the ad account from the ground up — correcting inefficiencies, implementing cost controls, and introducing structured scaling across Meta and Google.
YTD, YouSwim had achieved +36% growth in US sales, +11% higher AOV, and a huge increase in site sessions — all while establishing a sustainable foundation for future scale.
Brands that we increased profits for:
The Brand
YouSwim is an industry-shaping fashion brand celebrated for its adaptive, inclusive swimwear — pieces that stretch to fit seven sizes in one, designed for every stage of life.
With a deeply loyal audience and a product built on self-confidence and longevity, YouSwim entered 2025 with incredible brand equity — but an ad account that wasn’t performing at the same level.
The creative foundation was exceptional.
The operational layer needed rebuilding.
That’s where Social Nucleus stepped in.
The Challenge
When we took over the account, it was clear the fundamentals weren’t aligned to best practice for scale:
- Campaigns were fragmented by audience rather than intent, limiting data volume and stability.
- Bidding was fully automated, with no cost controls or efficiency safeguards.
- Attribution relied on 7-day click, 1-day view, inflating data and clouding true performance.
- Collection and product-level structure didn’t exist, meaning high-performing SKUs were buried in broad campaigns.
The Result?
Strong creative potential, but inefficient spend, unstable delivery, and limited room for algorithmic optimisation.
Our objective was simple but ambitious:
Rebuild YouSwim’s performance system from the ground up — and make it scale.
The Strategy
The first step was a full structural overhaul — creating a cleaner, more scalable foundation that could actually let Meta’s automation work properly.
- Consolidated campaign architecture: We replaced multiple small-scale audience splits with collection-based campaigns, grouping products by category and intent rather than demographics.
- Learning stability: Fewer campaigns with higher data volume meant faster learning and steadier delivery.
- Simplified targeting: We used broad and Advantage+ audiences to fuel Meta’s discovery systems, eliminating overlap and wasted frequency.
This restructured architecture became the foundation for all subsequent growth — simple, scalable, and perfectly aligned with Meta’s machine learning framework .
Previously, YouSwim was running on AutoBid, giving the algorithm full freedom to spend — and consequently driving up CAC during high-demand periods.
We introduced cost caps and bid controls to manage efficiency and enforce profitability thresholds.
- Controlled volatility: Cost caps stabilised CAC during volatile auction windows.
- Selective pacing: We scaled spend based on real-time performance feedback, ensuring incremental efficiency gains without margin erosion.
- Structured growth: As we expanded budgets, cost caps allowed Meta to find profitable conversions first before exploring higher-cost segments .
The result was consistent daily spend efficiency and scalable account performance — a marked shift from reactive to controlled growth.
YouSwim’s attribution model was a major blind spot.
The account was previously running on 7-day click, 1-day view, which over-attributed sales and misled optimisation signals.
We shifted to 7-day click only, giving the algorithm cleaner conversion feedback and aligning reported performance with true incremental sales .
That change instantly improved decision accuracy.
It allowed us to make bidding, scaling, and creative decisions based on real performance — not inflated data.
We rebuilt the campaign architecture around collections and product intent.
Instead of one-size-fits-all ad sets, each campaign was structured to match specific buying motivations.
For example:
- “Core Swim” campaigns targeting proven hero SKUs.
- “New Season” campaigns focused on awareness and product discovery.
- “Bundle & Gift” campaigns optimised for multi-unit purchasing.
This structure created clarity. Each ad set served a clear purpose in the funnel, and budget could be shifted dynamically based on real contribution margin.
Once the structure was sound, we fully embraced Meta’s Andromeda delivery system — automation done right.
- Algorithmic delivery: Broader campaigns with diverse creative inputs gave Andromeda the signal density needed to optimise faster.
- Creative diversity: We introduced a high-volume pipeline of short-form videos, product showcases, and lifestyle imagery to combat fatigue and enhance delivery.
Automation synergy: Letting the algorithm work within a clean, cost-controlled environment delivered compounding efficiency gains over time .
The Execution
The rebuild touched every layer of performance:
- Account simplification: Fewer, broader campaigns aligned to collections, not audiences.
- Attribution reset: Switched from 7d click / 1d view to 7d click only, cleaning signal noise.
- Bidding structure: Introduced cost caps and phased scaling to protect CAC as spend increased.
- Creative cadence: Refreshed ad library weekly to align with Andromeda’s learning rhythm.
- Geographic focus: Doubled down on the US market, YouSwim’s most responsive and high-margin region.
- Measurement alignment: Implemented blended performance reporting across Meta and backend sales to ensure every scaling decision was ROI-positive.
Within 60 days, the account’s performance curve inverted — from fluctuating inefficiency to smooth, scalable growth.
The Results (2025)
- 🛒 36% More US Sales
- 📈 11% Higher AOV
- 🚛 30% More Orders
Performance Highlights:
- US market became YouSwim’s key growth driver.
- Traffic growth fuelled by algorithmic efficiency, not higher spend.
- Conversion efficiency improved across all ad sets following attribution and bidding optimisation.
- Meta account now operates at full best-practice alignment- simplified, stable, scalable.
The Outcome
YTD, YouSwim wasn’t just performing better — it was operating smarter.
A fragmented, over-automated account was rebuilt into a high-efficiency growth system:
- Structural simplicity.
- Controlled bidding.
- Clean data.
- Intent-driven campaigns.
- Sustainable scale.
The brand’s creative strength finally had the system it deserved behind it.
This rebuild didn’t just fix inefficiencies — it unlocked scalability that’s now driving consistent, compounding performance across 2025 and beyond.
Why It Worked
- Structure Before Scale: Clean, collection-based architecture stabilised learning and improved delivery quality.
- Data Integrity: Moving to 7-day click-only attribution restored accuracy and improved decision quality.
- Smart Cost Controls: Cost caps transformed volatility into predictable growth.
- Creative Breadth: Consistent ad variety kept Meta’s delivery system learning and reduced fatigue.
- Automation Mastery: Andromeda was allowed to perform within disciplined parameters — automation with control, not chaos.
The Takeaway
YouSwim’s 2025 turnaround shows the power of structure, control, and precision.
When creative excellence meets data integrity and disciplined execution, performance stops fluctuating — and starts compounding.
In just one year, we turned a high-potential brand into a scalable, profitable machine.
