What Is Marketing Efficiency Ratio, and How to Improve It

If you've spent any time in the digital marketing trenches, you've probably encountered a dizzying array of acronyms: ROAS, ROI, CAC, LTV, and the list goes on. Just when you thought you had them all figured out, along comes another one – MER.

MER, or Marketing Efficiency Ratio, is one of those metrics that sounds intimidating but is quite straightforward once you break it down. And more importantly, it's a crucial number that could make or break your marketing strategy.

In this comprehensive guide, I'll demystify MER, walk you through its calculation, compare it with ROAS, and share actionable strategies to improve your marketing efficiency ratio. Let's jump right in, shall we?

What is a marketing efficiency ratio?

Marketing Efficiency Ratio is a holistic metric that measures how efficiently your total marketing spend generates revenue across all channels and campaigns. In simpler terms, it tells you how many dollars you make for every dollar you spend on marketing.

Unlike more focused metrics that evaluate individual campaign performance, MER takes a bird's-eye view of your entire marketing ecosystem. It factors in all your marketing activities – from paid ads and email campaigns to content marketing and SEO efforts – and compares them against your total revenue.

Think of MER as the financial health check-up for your marketing strategy. If your MER is high, your marketing dollars are working hard for you. If it's low, it might be time to reassess where your budget is going.

Different ways to present the marketing efficiency ratio

While the basic concept remains the same, you can express your marketing efficiency ratio in different ways depending on your business context:

1. As a ratio (e.g., 3:1): You generate $3 in revenue for every $1 spent on marketing.
2. As a percentage (e.g., 300%): Similar to the ratio approach, this indicates that your revenue is 300% of your marketing spend.
3. As a multiplier (e.g., 3x): This format highlights how often your marketing spend generates revenue.

Each presentation has merits, but the essence remains the same: higher numbers indicate more efficient marketing efforts.

What is the formula for the marketing efficiency ratio?

The formula for calculating MER is refreshingly straightforward:

For example, if your business generated $500,000 in total revenue over a quarter and spent $100,000 on all marketing activities during the same period, your MER would be:

MER = $500,000 / $100,000 = 5

That means for every dollar you spent on marketing, you generated $5 in revenue – not too shabby!

However, ensure that your revenue and marketing spend figures cover the same period to make this metric genuinely insightful. Comparing last month's revenue with this month's ad spend will give you a distorted view of your efficiency.

Also, be comprehensive in what you include in 'Total Marketing Spend.' It's not just your ad spend; it encompasses all costs associated with marketing efforts, including agency fees, software subscriptions, content creation, email marketing, social media management, and more.

What is a good marketing efficiency ratio?

Now that we know how to calculate MER, the million-dollar question is: what number should we aim for? What constitutes a "good" marketing efficiency ratio?

As with many things in marketing, the answer is that it depends. Different industries, business models, and growth stages come with varying benchmarks. However, here are some general guidelines:

• MER < 1: You're spending more on marketing than you're generating in revenue. While this may be acceptable for startups in aggressive growth phases (think of it as investing in future growth), it is not sustainable in the long run.
• MER = 1: You're breaking even. Every dollar spent on marketing returns one dollar in revenue. While not dire, there's definitely room for improvement.
• MER ≥ 3: Experts suggest that a MER of 3 or higher is healthy for many businesses. You're generating $3 or more for every marketing dollar, which provides a good cushion for other operational costs.
• MER ≥ 5: Other sources consider a MER of 5 or above excellent, as your marketing efforts are yielding significant returns. However, if your MER is exceptionally high (say, 10 or above), it may be worth considering whether you are underinvesting in marketing and potentially missing out on growth opportunities.

Remember, these are just guidelines. Your industry, gross margin, and business objectives are key factors in determining the right MER for you.

For instance, e-commerce businesses with high product costs might aim for an MER of 5 or higher, ensuring that marketing costs consume no more than 20% of their total revenue. On the other hand, SaaS companies often operate using a subscription model, where customer lifetime value (LTV) is a key metric. If retention is strong, they may accept a lower MER upfront, knowing they'll recover marketing costs over time through recurring revenue.

The key is to benchmark against your industry peers and your historical performance to set realistic MER targets.

What is MER vs. ROAS?

MER and ROAS (Return on Ad Spend) are two peas in the marketing metrics pod, but they serve different purposes. Let's break down the key differences.

Scope of measurement:

• MER: Evaluates all marketing efforts against total revenue. It's a holistic view of your marketing efficiency.
• ROAS: Specifically measures the return from advertising spent on a specific campaign.

Formula:

• MER: Total Revenue / Total Marketing Spend
• ROAS: Total Ad Revenue / Ad Spend

Example: 

Let’s break it down with a scenario you might actually face.

Your business pulled in $500,000 in revenue last month. You spent $100,000 across all marketing activities—paid ads, email tools, agencies, branding work, influencers, everything.

Of that $100K:

• $60,000 went to ad campaigns
• Those campaigns generated $276,000 in tracked revenue

Now, what do these numbers tell us?

• MER = $500K ÷ $100K = 5.0
  You made $5 for every $1 you spent on overall marketing activities
• ROAS = $276K ÷ $60K = 4.6
  You made $4.60 for every $1 spent on paid ads alone.

Seems solid, right? But let’s zoom in a little with a case point.

How that $60K ad spend actually breaks down:

• Campaign A:
  Spent $30K and made $240K → ROAS = 8.0 🚀
  Crushing it.
• Campaign B:
  Spent $30K and made just $36K → ROAS = 1.2 😬
  That’s a loss once you factor in margins, fulfillment, and overhead.

The average ROAS across both campaigns is 4.6, which may seem decent at first glance. But if you only look at the high-level ROAS, you could miss the fact that half your ad budget is barely breaking even or is actually losing money after costs. 

That’s where understanding MER alongside ROAS really matters.

If ROAS is high but MER is low, your ads are doing fine, but bloated overhead or non-performing channels might be dragging you down.

If MER is high but ROAS is weak, your other efforts, such as email or organic, might be doing the heavy lifting.

When to use MER vs. ROAS

We’ve already established that MER and ROAS are both robust metrics; however, knowing when to use each can significantly impact your marketing analytics strategy.

Use MER when:

✔️ You want to assess the overall efficiency of your marketing strategy, not just specific campaigns

✔️ You're making high-level budget allocation decisions across marketing channels

✔️ You're reporting to C-suite executives or stakeholders interested in the big picture

Use ROAS when:

✔️ You're optimizing specific ad campaigns or channels

✔️ You want to compare the performance of different ad sets or creative variations

✔️ You're making day-to-day tactical decisions about ad spend

✔️ You're working with agencies or teams focusing on specific advertising platforms

In short, MER gives you the forest view, while ROAS shows you the trees.

7 best practices to increase your marketing efficiency ratio

Now that we understand MER and how it differs from ROAS, let's get to the exciting part: how to improve it. Here are seven proven strategies to achieve a higher MER:

1. Focus on high-ROI channels

Not all marketing channels are created equal. Some might deliver stellar results for your business, while others might be money pits.

Analyze your marketing analytics data to identify which channels yield the highest returns. Then, reallocate your budget to prioritize these high performers. That doesn't mean abandoning other channels entirely but being more selective with where you invest heavily.

For example, if your Facebook ads consistently outperform your Google ads, shifting a portion of your Google budget to Facebook might make sense. Similarly, if email marketing delivers a better ROI than social media, consider ramping up your email campaigns.

The key is to let data-driven marketing insights guide your channel strategy rather than following generic best practices or industry trends.

2. Optimize your conversion funnel

Your marketing efficiency isn't just about getting people to your website; it's about converting them into paying customers. A leaky conversion funnel can significantly hamper your MER, regardless of how brilliant your acquisition strategies are.

Audit each stage of your customer journey:

• Is your website loading quickly?
• Is your value proposition clear?
• Is your checkout process frictionless?
• Are there any unnecessary steps that might cause drop-offs?

Even minor improvements in conversion rates can have a dramatic impact on your marketing efficiency ratio. A 20% increase in conversion rate means you're getting 20% more revenue from the same marketing spend – that's a direct 20% boost to your MER!

Heatmaps and user session recordings can provide valuable insights into how visitors interact with your site, helping you identify areas for improvement.

3. Leverage remarketing and retention strategies

Acquiring a new customer can cost up to five times as much as retaining an existing one. Customer retention is a powerful, often underutilized lever for improving your marketing efficiency ratio.

Start with remarketing: re-engage visitors who’ve shown interest but didn’t convert. These campaigns typically have lower costs and higher conversion rates than cold acquisition efforts, meaning more revenue with less spend.

Then double down on retention. By increasing the lifetime value of each customer, you grow your total revenue without inflating your marketing budget. Some tried-and-true tactics:

• Email nurture sequences
• Loyalty or referral programs
• Post-purchase follow-ups
• Cross-selling and upselling campaigns

The more value you extract from your existing audience, the better your MER will be because you're boosting revenue without spending more to get it.

4. Adopt a multi-touch attribution model

Many businesses still rely on basic attribution models, such as last-click, which overlook a customer's entire journey leading up to conversion. This overlook can lead to poor budget decisions and a distorted view of what drives results.

To improve your marketing efficiency ratio, adopt a multi-touch attribution model. This approach gives credit to all the touchpoints that influence a conversion not just the final click, helping you see which channels contribute to success across the entire funnel.

For example, your social ads might not drive direct purchases but could consistently spark interest, leading to eventual conversions. Without multi-touch attribution, you might cut spend on those ads, thinking they don’t work—when, in reality, they’re doing heavy lifting early on.

Smarter attribution = smarter spend = stronger MER. 

Marketing analytics tools that offer advanced attribution capabilities can be invaluable for this analysis.

5. Refine your targeting strategy

Casting too wide a net can waste ad spend and reduce your marketing efficiency ratio. Instead, focus on reaching the audiences most likely to convert—and bring the highest value.

Use your customer data to create detailed buyer personas, and then build lookalike audiences based on your most profitable customers. Regularly audit your personas and audience segments to ensure they still align with evolving customer behaviors and preferences. For e-commerce brands, prioritize promoting products with higher profit margins to maximize the effectiveness of your ad dollars.

Platforms like Meta and Google offer advanced targeting tools that let you zero in on high-intent segments based on behavior, interests, demographics, and more. The more precise your targeting, the more efficient your marketing spend, and the higher your MER.

6. Negotiate better rates with vendors and agencies

Your marketing spend isn't just about ad budgets; it also includes agency fees, tool subscriptions, and various service providers. Reducing these costs without compromising quality can directly improve your MER.

Don't be afraid to negotiate with your vendors, especially if you've been a loyal customer. Many agencies and service providers are willing to offer better rates to retain valuable clients.

Additionally, regularly review your marketing tech stack to identify redundant tools or services that can be consolidated or eliminated. The SaaS landscape is constantly evolving, and there might be more cost-effective alternatives to the tools you've used for years.

7. Implement strong A/B testing protocols

Systematic A/B testing across all marketing elements – from ad creative and landing pages to email subject lines and call-to-action buttons – can incrementally improve performance without increasing spend.

The key is to establish a rigorous testing framework:

• Test one element at a time for precise results
• Ensure statistical significance before drawing conclusions
• Document and share learnings across teams
• Continuously iterate based on test results

Even modest improvements in click-through or conversion rates can compound over time, leading to substantial gains in marketing efficiency.

By implementing these seven strategies, you can systematically enhance your marketing efficiency ratio and extract more value from every marketing dollar spent. The beauty of MER improvement is that it doesn't necessarily require increasing your budget – often, it's about making smarter decisions with the resources you already have.

Conclusion

At the end of the day, your marketing efficiency ratio isn’t just another vanity metric—it’s a straight-up gut check for how hard your marketing dollars are working. Whether running lean or scaling fast, keeping a sharp eye on MER alongside your ROAS can help you steer the ship with way more confidence.

And if you're still flipping between five tabs trying to figure out what's working (been there), it’s probably time to level up with a proper digital marketing dashboard. One that gives you a real-time, bird’s-eye view of your performance marketing efforts—without the spreadsheet headaches.
