Why ROAS is Holding You Back and How MER Can Drive Real Growth

Introduction: The Problem with ROAS‍

For years, Return on Ad Spend (ROAS) has been the go-to metric for marketers. At first glance, it seems like a no-brainer: track how much revenue you generate for every dollar spent on advertising. Simple, right?

But here’s the catch: ROAS is a narrow, outdated metric that doesn’t account for the complexity of today’s omni-channel marketing environment.

The reality is this: optimizing for ROAS can lead to short-term wins but often misses the bigger picture—your overall business growth.

That’s where Media Efficiency Ratio (MER) comes in.

What is MER?

‍Media Efficiency Ratio (MER) = Total Revenue ÷ Total Media Spend.

Unlike ROAS, which focuses on individual campaign performance, MER provides a holistic view of your marketing effectiveness. It connects every dollar spent on media—across all channels—to your total revenue, helping you understand how well your marketing budget is driving growth.

Why ROAS Falls Short

1. ROAS Measures Individual Campaigns, Not Business Success
   ROAS might tell you which campaigns perform best on a specific platform, but it won’t show you if your business is actually growing. It’s like measuring one tree and ignoring the health of the entire forest.
2. ROAS Misses the Multi-Channel Customer Journey
   Customers interact with your brand across multiple touchpoints before converting. ROAS focuses on one channel at a time, leaving gaps in your data.
3. ROAS Can Be Easily Manipulated
   It’s all too easy to inflate ROAS by optimizing for low-value conversions or cutting spending to the bone—at the expense of long-term growth.

Why MER Wins

1. MER Tracks the Full Picture
   By comparing your total revenue to your total media spend, MER provides a complete view of your marketing’s impact across all channels.
2. MER Aligns Marketing with Business Goals
   MER shifts the focus from vanity metrics to what really matters—driving sustainable revenue growth.
3. MER is Harder to Manipulate
   Unlike ROAS, MER forces transparency. It’s an honest reflection of how well your media budget is contributing to your business’s bottom line.

How to Start Using MER

Transitioning from ROAS to MER requires a mindset shift. Here’s how to get started:

1. Audit Your Media Spend and Revenue Streams
   Gather data from all your channels—digital ads, social media, influencer marketing, and content production. Include every dollar spent on media.
2. Calculate Your MER
   Use the formula: Total Revenue ÷ Total Media Spend. This will give you a baseline to measure performance.
3. Set New Benchmarks and Goals
   Shift your team’s focus from ad-specific ROAS to MER as your primary KPI.
4. Optimize for Growth
   Use MER to identify what’s working and allocate your budget more effectively.
