The Problem

The company could not determine which marketing channels were driving qualified buyers and revenue. Without reliable data, it was impossible to identify wasted spend, compare campaign performance, or reallocate the budget to the channels delivering the highest return.

My Approach

  1. Audit of the existing analytics setup
  2. Data quality assessment and issue identification
  3. Implementation of accurate tracking in GA4 and GTM
  4. Implementation of e-commerce events and parameters
  5. Testing, validation, and documentation

Conclusions

The business was able to stop spending on channels that did not generate sales and reallocate its budget to the most profitable campaigns. The team gained a clear understanding of where qualified buyers came from, which products and advertising activities generated revenue, and where potential orders were being lost. This helped improve marketing returns, reduce customer acquisition costs, and scale sales based on actual business outcomes rather than clicks and visits.

  • Accurate data for decision-making
  • Growth in conversions and revenue
  • Transparent analytics across all channels
  • A scalable and maintainable system
We now know exactly what is happening on the website and which channels bring in customers. This has helped us increase revenue and optimize our marketing budget.
