The Challenge
GrowthBox, a subscription box company, was spending £50,000 per month on Google and Facebook ads but struggling to achieve profitability. Their ROAS had dropped to 2.3x, making customer acquisition unsustainable.
Their main challenges included:
- Rising CPCs in a competitive market
- Poor conversion rates on landing pages
- Inefficient campaign structure
- Limited tracking and attribution
Our Approach
We took a full-funnel approach to PPC optimisation, focusing on efficiency at every stage.
Phase 1: Tracking & Attribution
Before optimising, we needed accurate data. We implemented:
- Enhanced conversion tracking with Google Tag Manager
- Server-side tracking for better attribution
- Custom dashboards for real-time performance visibility
Phase 2: Campaign Restructure
We completely rebuilt their campaign architecture:
- Segmented campaigns by intent and product category
- Implemented SKAGs (Single Keyword Ad Groups) for high-value terms
- Created dedicated remarketing campaigns for cart abandoners
Phase 3: Landing Page Optimisation
We A/B tested landing page variations and improved:
- Page load speed (from 4.1s to 1.4s)
- Trust signals and social proof
- Checkout flow simplicity
- Mobile experience
Phase 4: Creative Testing
We developed a systematic creative testing framework:
- Tested 20+ ad variations per month
- Identified winning emotional triggers
- Optimised for both CTR and conversion rate
The Results
Within 4 months, GrowthBox saw transformative results:
- ROAS improved from 2.3x to 5x
- Cost per acquisition dropped by 32%
- Monthly revenue grew to £250k (from £115k)
- Conversion rate increased by 47%
The improved efficiency allowed them to scale spend confidently, knowing every pound was working hard.
