Marketing budgets are under greater scrutiny than ever. Amid this pressure, Gain Theory — a global marketing effectiveness consultancy — delivers a timely reminder: advertising isn’t a cost center, it’s a strategic growth engine. Their latest report, “Measure, Thrive, Optimize: How to Demonstrate Advertising’s Value and Boost Growth,” provides rigorous evidence that advertising generates a 2.9x return on investment when executed and measured effectively.
Based on 75 real-world company-market combinations, the study outlines how advertisers can secure budget confidence, achieve consistent growth, and prove their impact to stakeholders.
Insights from the Report
1. Advertising’s True ROI
- On average, companies that invest 3% of revenue in advertising see an 8.7% contribution to total sales.
- This translates into a 2.9x ROI, providing a robust case for continued or increased advertising investment.
2. Data-Driven Budget Confidence
- The report offers marketers concrete proof to validate advertising’s value — especially crucial in today’s volatile market environment.
- Companies that actively measure and optimize advertising see sustained year-on-year growth, reinforcing the importance of consistent performance tracking.
3. Growth Levers: Spend More and Spend Wisely

- The most successful companies combine both strategies — investment and efficiency — to maximize outcomes.
4. Sector-Specific Challenges
- CPG brands face steeper challenges due to lower contribution rates.
- These brands must adopt more sophisticated measurement techniques to remain competitive.
Strategic Pathways for Marketers
1. Establish Robust Measurement Programs
- Marketing Mix Modelling (MMM) is ideal for large enterprises with complex campaigns.
- A/B Testing suits smaller businesses or brands lacking sufficient data access.
- Regardless of method, measurement is essential for linking spend to growth.

- Don’t just increase budgets — improve allocation strategies using channel-specific performance insights.
- Data-driven media planning ensures resources are invested where they generate the most impact.
