Episode notes
ROAS is Outdated
- ROAS is no longer the primary metric for evaluating marketing success.
- Focus on metrics that drive long-term growth like Media Efficiency Ratio (MER) and New Customer Acquisition Cost (NCAC).
Client-Centric Approach
- Agencies must adopt a client-centric approach, prioritizing business growth over platform metrics.
- Understand the client's business deeply and work as partners to achieve their goals.
Measuring Business Health
- John Moran’s Google Ads agency measured success based on business health, not just Google Ads metrics.
- This holistic approach was limited by other agencies' focus on in-app metrics like ROAS.
