The Challenge
Taxfix faced growing uncertainty in where to invest marketing spend; combined with difficulty in scaling performance and a lack of clarity across upper-funnel activities. These challenges were rooted in measurement limitations; while previous methodologies provided data, the existing approach over-credited baseline demand rather than isolating the true drivers of incremental growth. Taxfix set out to gain a more sophisticated understanding of their marketing activity, seeking the strategic direction and execution required to transform measurement into a tangible engine for growth.
The Approach
Taxfix reframed measurement as a tangible driver of growth by enabling a forward-looking, outcome-driven approach that produces better investment decisions and long-term performance. This approach was rooted in solving specific stakeholder pain points through an iterative, context-driven strategy that mirrored the nuances of the Taxfix market reality.
- Distinguishing Between Organic Market Demand and True Media-Driven Impact
Google’s Meridian was deployed to establish a precise baseline. By integrating Google Query Volume and return frequency data, the model was designed to separate organic market demand from media-driven impact and address historical channel over-crediting. To ensure accuracy, a bespoke dynamic model was developed to account for brand equity, macro-economic conditions, and legislative-driven demand. Critically, layers of seasonality data were integrated, allowing the system to distinguish between organic seasonal surges and true media-driven growth. - Connecting Channels, Data, and Experimentation
Previously siloed data was unified across channels, integrating YouTube reach, Geo Lift experimentation, and search behavior signals. This approach aimed to create a centralized view of incrementality, designed to isolate the specific drivers of growth across the entire digital ecosystem. - Testing, Learning, and Scaling
Measurement was identified as a structured test-and-learn roadmap rather than a one-off project. Taxfix required a strategic bridge between raw outputs and execution, providing the data-backed recommendations necessary to justify budget shifts. “Investment thresholds” were highlighted for Taxfix, demonstrating where spend increases were necessary for channels to achieve statistical significance and measurable impact within the model.
The Outcome
This transformed measurement from a reporting function into a learning system that informs ongoing growth decisions giving Taxfix the clarity, confidence, and control to scale investment more effectively and drive stronger returns.
- More Accurate, Actionable Insights
Channel-level inflation was reduced by 54%, and the understanding of true baseline demand improved by 10 percentage points creating a far more reliable and actionable foundation for investment decisions. The model also revealed structural investment inefficiencies, prompting targeted budget reallocation to improve data variation and strengthen future measurement accuracy.
- More Confident Investment Decisions
With a clearer view of incrementality, Taxfix was able to reallocate budget toward high-impact upper-funnel channels with confidence, including CTV and YouTube. - Scalable, Sustainable Growth
Taxfix achieved a doubled YOY increase in upper-funnel investment, building a more balanced, future-facing growth strategy focused on long-term impact rather than short-term signals.
“We have transitioned from using measurement as a tool for static output to leveraging it as a dynamic engine for growth. Deploying Meridian, our revised approach interconnects rigorous modeling with real-world experimentation, providing the strategic clarity needed to confidently reallocate investment toward the high-impact channels that drive true incremental value.”
