Real A/B testing results and UX improvements that doubled conversion rates from 2% to 6.8% in 90 days without increasing ad spend. Learn the exact tests we ran and the results we achieved.
The Challenge
Our client was spending £20,000 monthly on paid ads, generating £40,000 in revenue with a 2% conversion rate. They wanted to scale but couldn't afford to increase ad spend. The solution: improve conversion rate so the same traffic generates more revenue.
Our CRO Process
We followed a data-driven CRO process: analyze, hypothesize, test, measure, iterate.
Phase 1: Analysis & Research (Week 1-2)
We analyzed their store using multiple tools:
- Heatmaps: Identified where users clicked, scrolled, and got stuck
- Session Recordings: Watched real user sessions to identify friction points
- Google Analytics: Analyzed user flow and drop-off points
- Customer Surveys: Asked recent purchasers and non-purchasers why they did/didn't buy
Key findings:
- 78% cart abandonment rate
- Mobile checkout had 5 steps (too many)
- No trust signals on product pages
- Shipping costs revealed too late (at checkout)
- No urgency or scarcity elements
Phase 2: Hypothesis & Testing (Week 3-10)
Test 1: Simplified Checkout Process
Hypothesis: Reducing checkout steps from 5 to 2 will reduce friction and increase conversions.
Changes:
- Combined shipping and billing information
- Removed unnecessary fields
- Added guest checkout option
- Saved progress automatically
Result: +34% conversion rate increase. Cart abandonment dropped from 78% to 62%.
Test 2: Trust Signals on Product Pages
Hypothesis: Adding trust signals will reduce purchase anxiety and increase conversions.
Changes:
- Added customer review count and average rating
- Displayed "X people bought this in the last 24 hours"
- Added security badges (SSL, payment security)
- Showed return policy and money-back guarantee
Result: +18% conversion rate increase on product pages.
Test 3: Shipping Cost Transparency
Hypothesis: Showing shipping costs earlier will reduce checkout abandonment.
Changes:
- Added shipping calculator on product pages
- Showed "Free shipping over £50" prominently
- Added shipping cost to cart summary
Result: +12% conversion rate increase. Cart abandonment dropped another 8%.
Test 4: Urgency & Scarcity Elements
Hypothesis: Creating urgency will motivate faster purchases.
Changes:
- Added "Only 3 left in stock" for low inventory items
- Showed countdown timer for limited-time offers
- Displayed "X people viewing this product"
Result: +15% conversion rate increase. Time to purchase decreased by 23%.
Test 5: Mobile Optimization
Hypothesis: Optimizing mobile experience will improve mobile conversions (60% of traffic).
Changes:
- Larger tap targets for buttons
- Sticky add-to-cart button
- Simplified mobile navigation
- Faster mobile load times
Result: +28% mobile conversion rate increase.
Phase 3: Optimization & Scaling (Week 11-12)
After identifying winning tests, we:
- Implemented all winning changes site-wide
- Continued testing new hypotheses
- Optimized for different traffic sources
- Created personalized experiences for returning customers
The Results
With the same £20,000 ad spend and 2,000 monthly visitors, revenue increased from £40,000 to £136,000 monthly—a 240% increase without spending more on ads.
Key Takeaways
The biggest lesson: small changes compound. No single test doubled the conversion rate, but together, they created a 240% increase. Second, mobile optimization is non-negotiable—60% of traffic was mobile, but mobile conversions were lagging. Finally, trust and transparency matter more than we think—showing shipping costs and trust signals significantly reduced abandonment.
