Confidentiality Notice
Due to confidentiality and data protection agreements, the client’s name and internal screenshots cannot be publicly shared.
This case study focuses on the business challenges, technical strategy, and measurable outcomes of the engagement.
Executive Summary
A rapidly growing UK e-commerce company had reached a critical scaling phase.
Marketing budgets were increasing.
New acquisition channels were planned.
Performance reports looked strong.
But leadership had lost trust in the data behind those reports.
Backona delivered a complete rebuild of the company’s marketing data infrastructure — from consent and tracking foundations to server-side architecture and AI-driven insights via Backona AI.
The result:
A transformation from inflated, unreliable reporting to a decision-grade data system that now supports confident scaling, compliant growth, and long-term efficiency.
Business Context
The client had moved beyond early-stage growth and entered a scale-up phase, facing:
- Rising paid media budgets
- Increasing pressure on ROAS and profitability
- Expansion into new channels, including LinkedIn Ads
At this stage, inaccurate data was no longer a reporting inconvenience.
It had become a strategic and financial risk.
Scaling on distorted signals would amplify waste rather than growth.
Before investing further capital, leadership needed certainty.
The Core Problem: Data Existed — But It Could Not Be Trusted
Despite using multiple analytics and advertising platforms, the team could not confidently answer:
- Which channels genuinely drive revenue?
- Are conversion figures accurate or inflated?
- Can ad platforms optimise effectively with this data?
- Is attribution trustworthy across platforms?
A full audit revealed systemic weaknesses throughout the tracking stack.
Key Challenges Identified
1️⃣ Faulty Consent Setup
- GDPR exposure risk
- Inconsistent data collection
- Poor modelling reliability
2️⃣ Duplicate Conversion Events
- Inflated performance metrics
- Artificially boosted ROAS
- Misleading revenue attribution
3️⃣ 10–30% Data Loss
- Ad blockers
- Browser restrictions
- Client-side-only tracking
4️⃣ Weak Ad Platform Learning
- Incomplete signals to Meta, Google, and LinkedIn
- Reduced optimisation efficiency
5️⃣ Upcoming Channel Launch Without Proper Tracking
- Risk of blind spend
- No reliable performance validation
In short:
Spend was scaling faster than insight.
Our Strategy: Building a Future-Proof Data Foundation
Rather than applying temporary fixes, Backona designed a complete transformation based on four principles:
- Accuracy
- Scalability
- Compliance
- Long-term leverage
1️⃣ Audit & Measurement Strategy
We began with a comprehensive technical and strategic audit of:
- GA4 configuration
- Google Tag Manager setup
- Event logic and conversion definitions
- Attribution consistency
- Platform integration architecture
This allowed us to:
- Remove inflated and redundant signals
- Redefine conversions aligned with real business KPIs
- Establish a clean measurement framework
The goal was clarity, not complexity.
2️⃣ Consent & Privacy as Infrastructure
We implemented Google Consent Mode v2 as a structural component of the data architecture — not merely a compliance overlay.
This ensured:
- Proper consent handling across all platforms
- Full GDPR and ICO alignment
- Preserved trend visibility via compliant modelling
Privacy became a stable foundation rather than a constraint.
3️⃣ Server-Side Tracking Implementation
To reduce signal loss and improve reliability, we migrated tracking logic into a server-side architecture.
Business Impact:
- Minimized browser and ad-blocker-related data loss
- Stabilised conversion volumes
- Implemented robust deduplication logic
- Improved signal quality for ad platform optimisation
Trust in reporting was restored.
So was confidence in automated bidding.
4️⃣ Centralised Multi-Platform Event Architecture
We introduced a “collect once, distribute everywhere” model.
Events are captured centrally and consistently sent to:
- Google Analytics 4
- Google Ads
- Meta
This eliminated platform discrepancies and ensured every system operated from the same validated event source.
5️⃣ Privacy-Safe Identity Matching
To improve attribution and match rates without compromising compliance, we applied SHA-256 hashing for user identifiers.
These identifiers are:
- Processed server-side
- Never exposed in browsers
- Fully compliant with platform policies
This significantly enhanced audience matching while maintaining strict privacy standards.
6️⃣ BigQuery Integration & Backona AI Deployment
We connected GA4 to BigQuery, giving the client full ownership of raw historical data.
On top of this foundation, we deployed Backona AI, enabling the team to:
- Ask natural-language performance questions
- Instantly analyse trends
- Identify inefficiencies
- Generate insights without manual report building
Analytics shifted from a bottleneck to an operational advantage.
Results & Impact
Operational Outcomes
- Fully compliant consent management
- Clean, deduplicated conversion tracking
- Stable server-side architecture
- Consistent cross-platform attribution
Strategic Outcomes
- Stronger ad platform learning signals
- Renewed confidence to scale spend
- Unified customer journey visibility
- Faster channel expansion capability
Decision-Level Benefits
- Underperforming segments identified earlier
- Significant reduction in manual reporting time
- Clearer budget allocation decisions
- Reduced reliance on assumptions
Long-Term Business Value
This project delivered far more than cleaner analytics.
It created:
- Lower marginal costs of growth
- Higher signal quality for algorithmic optimisation
- Reduced dependency on manual analysis
- A scalable infrastructure for data-driven decisions
By leveraging accurate signals and eliminating inflation, the client now has a clear path toward:
Up to 50% improvement in marketing cost efficiency over time — achieved through precision, not cuts.
Conclusion
This transformation demonstrates how modern marketing infrastructure directly impacts scalable growth.
By rebuilding the foundation — from consent and tracking to server-side architecture and AI-powered insights — the client moved from unreliable reporting to strategic clarity.
Today, their marketing team can:
- Scale confidently
- Optimise efficiently
- Allocate budget intelligently
- Make decisions grounded in trustworthy data
For Backona, this project reinforces our role as a growth infrastructure partner — helping ambitious companies move from guesswork to scalable, compliant, and profitable growth.
