Why ROI is Important for Marketers
- Justify Budget and Spending – Demonstrating a strong ROI helps secure future marketing budgets and ensures resources are allocated effectively.
- Optimise Campaign Performance – By tracking ROI across different marketing channels, you can identify what’s working and adjust strategies accordingly.

- Align with Business Goals – Marketing teams that focus on ROI align their efforts with overall business profitability, making them valuable strategic partners.
Limitations of ROI
While ROI is a powerful metric, it doesn’t always tell the full story.
Factors like brand awareness, customer lifetime value (CLV), and long-term engagement don’t always translate into immediate returns but are still essential for sustainable growth. That’s why ROI should be used alongside other key marketing metrics for a complete picture.
