Measure your blended return on investment by comparing total revenue against total ad spend across all channels.

Marketing Efficiency Score:
Marketing Efficiency Ratio (MER) is commonly known as the "blended" ROAS (Return on Ad Spend). It provides a holistic view of your marketing performance by measuring the total revenue generated against the total advertising spend across all platforms and channels, accounting for the combined impact of your marketing efforts.
MER = Total Revenue / Total Ad Spend
Consider an e-commerce business that generated a Total Revenue of $50,000 while allocating a combined Ad Spend of $10,000 across various digital platforms.
In this scenario, the MER of 5.0 suggests that for every dollar spent on ads, the company generated five dollars in total revenue, indicating efficient customer acquisition and strong organic performance.
A "good" ratio depends on your industry and profit margins. Generally, an MER between 3.0 and 4.0 is considered healthy for most e-commerce brands, though higher is always better for capital efficiency.
ROAS typically tracks specific platform attribution (like Facebook or Google Ads). MER looks at the big picture, including revenue from organic search and direct traffic that may have been influenced by ads but not directly tracked.
When scaling spend, individual platform ROAS often appears to drop due to attribution limitations. MER acts as your "true north," helping you verify if your total business is still growing profitably as you increase investment.
