PPC results in 82% more revenue for Corza Eye

The Problem

When we started working with Corza Eye, their PPC activity wasn’t meeting expectations. Despite strong demand, campaigns weren’t reaching the right decision-makers. Budgets weren’t being used efficiently, and conversion costs were too high.

One key issue was buried in the setup: revenue wasn’t tracking in GA4. A login step mid-funnel was breaking Google’s UTM tracking, so while purchases were recorded, no value was being attributed. This meant campaigns could only be optimised for volume, not value.

The Solution

We carried out a full account audit and delivered both technical and strategic improvements:

• Fixed a key GA4 issue so logins no longer triggered new sessions, allowing revenue to flow back into GA properly.
• Switched top-performing campaigns from Maximise Conversions to Maximise Conversion Value, with a target ROAS to guide spend toward profitability.
• Improved all ad creative to achieve “Excellent” quality scores, boosting visibility and click-through rate.
• Streamlined the campaign structure by removing redundant keywords and replacing them with broader, more efficient terms.
• Consolidated audience lists into one master list to reduce overlap and wasted spend.

The Results

In just three months, these changes unlocked strong, sustainable growth. Conversion rates more than doubled (+130%), and revenue increased by 82%. ROAS rose by 115%, and cost per conversion dropped by 42%.

Fixing what was broken and connecting performance with value allowed us to set the foundation for ongoing optimisation and scale.
