MER vs ROAS

MER (Marketing efficiency ratio)

MER, or Marketing Efficiency Ratio, is a critical metric that measures the effectiveness of marketing campaigns by comparing the revenue generated from marketing activities to the total marketing spend.

It is calculated by dividing the revenue generated from marketing activities by the total marketing costs, providing insights into how efficiently marketing dollars are being spent and the return on investment for marketing efforts.

For example, if you make $100 from selling lemonade, but you only spent $20 on signs and ads, your MER would be 5. That means for every dollar you spent on marketing, you made $5 in return.

MER is essential for businesses as it helps in optimizing marketing budgets, identifying profitable channels, making informed decisions about resource allocation, and evaluating the overall impact of marketing campaigns.

By tracking MER over time, businesses can gain valuable insights into their marketing strategy, improve marketing ROI, and optimize marketing spend to drive sustainable growth and profitability.

The Upside of MER:

MER is like having a bird’s eye view of how your marketing game is going. It gives you a quick peek into whether your marketing efforts are paying off or not. And the best part? You don’t need to be a math whiz to figure it out. It’s as simple as adding and dividing without needing fancy tools or confusing formulas.

Another cool thing about MER is that you can keep tabs on it all by yourself. No need to rely on shady data from outside sources. If your MER starts going down, it’s like a red flag telling you that you might be wasting your precious marketing dollars on stuff that’s not bringing in the cash. Plus, it helps you figure out where to put your money for marketing so you don’t throw it away on things that don’t work.

MER is also like a performance report card for your marketing efforts. It lets you see if your campaigns are hitting the mark or if they’re falling flat. And over time, you can use it to spot trends and patterns in how well your marketing is doing. It’s like having your own personal coach nudging you to get better at the marketing game.

The Downside of MER:

But like everything, MER has its limitations. It’s like trying to see the world through a keyhole instead of a wide-open door. While it gives you a general idea of how your marketing is doing, it doesn’t dive deep enough to tell you which specific ads are killing it and which ones are flopping.

Keeping track of all your spending on ads and how much dough they bring in can be a bit of a headache. And for some businesses, it’s like trying to herd cats. Plus, MER might not give you the full scoop on how your ads are impacting your business’s overall growth. It’s like looking at a puzzle with missing pieces. And since it only looks at money spent on ads and the cash they rake in, it might miss out on other important stuff that affects your marketing success.

In brief

MER’s Advantages:

  • Offers a broad overview of marketing performance and ROI.
  • Simple and quick to calculate, no need for complex tools.
  • Allows independent monitoring without relying on external data.
  • Identifies wasted budget and guides resource allocation effectively.
  • Maximizes marketing impact by evaluating ROI.
  • Acts as a performance indicator, aiding campaign assessment.
  • Facilitates long-term performance evaluation and trend identification.
  • Fosters a culture of continuous improvement.

MER’s Drawbacks:

  • Doesn’t delve into specific ad performance.
  • Requires meticulous tracking of expenses and sales.
  • Might not fully capture the impact on overall business growth.
  • Provides a limited view of marketing performance.

Let’s chat about Return on Ad Spend (ROAS) – it’s like the superhero of advertising metrics, but even superheroes have their weaknesses.

ROAS (return on ad spend)

ROAS, or Return on Ad Spend, is a marketing metric that measures the revenue generated for every dollar spent on advertising.
It is calculated by dividing the conversion value (revenue) by the cost of the ad campaign.

A high ROAS indicates that the marketing efforts are generating significant revenue, while a low ROAS suggests that the advertising strategy needs improvement.

ROAS is essential for quantitatively evaluating the performance of ad campaigns and how they contribute to an online store’s bottom line.
Combined with customer lifetime value, insights from ROAS across all campaigns inform future budgets, strategy, and overall marketing direction

ROAS is different from ROI (Return on Investment) and CPA (Cost Per Acquisition). ROAS focuses on revenue earned by ad spending, while ROI generally evaluates the revenue generated by a business expenditure. CPA looks only at the cost involved in acquiring a customer, without evaluating the revenue generated by a conversion

The Bright Side of ROAS

ROAS is your trusty sidekick when it comes to understanding how much cash your ads are bringing in for every dollar you throw their way. It’s like having a magic crystal ball that shows you which ad channels are pulling their weight, so you can focus your efforts where they count. Plus, it helps you fine-tune your ads, making them hit the bullseye with your audience. And the best part? It’s super easy to understand and makes reporting a breeze. Armed with ROAS insights, you can tweak your strategies on the fly, saving money and seeing results faster.

The Not-So-Bright Side

But like any superhero, ROAS has its kryptonite. Sometimes, it’s so focused on short-term wins that it misses the bigger picture of long-term revenue. Ads might be just one piece of the puzzle – other factors like offline ads and brand recognition can muddy the waters. And while ROAS might look impressive with a small customer base, it doesn’t show the full potential of reaching a larger audience. Oh, and don’t forget about those sneaky fees and commissions that can eat into your profits – they need to be factored into your ROAS calculations too.

In brief:

Pros of ROAS:

  • Channel selection
  • Ad optimization
  • Simplicity in reporting
  • Informed decision-making

Cons of ROAS:

  • Short-term focus
  • Incompleteness
  • Volume considerations
  • Partner and vendor costs
  • In-house personnel expenses

Factors that affect ROAS

When calculating Return on Ad Spend (ROAS), several factors come into play that can influence the outcome.

Firstly, operating costs and profit margins play a crucial role. A higher profit margin often translates to a higher ROAS, while lower operating costs can also contribute to a better outcome. Additionally, the size of the market and the level of competition can impact ROAS. In larger markets with less competition, achieving a higher ROAS may be more feasible compared to smaller, more competitive markets.

The quality of the product or service being advertised is another significant factor. Higher-quality offerings tend to lead to higher ROAS due to increased customer satisfaction and repeat business. Pricing strategy is also key, with a well-thought-out approach considering the target audience, competition, and market conditions likely to yield a higher ROAS.

The quality of the ads themselves matters too. Well-designed, relevant, and engaging ads typically result in a higher ROAS. Segmenting the target audience and tailoring ads accordingly can further enhance ROAS by increasing relevance and effectiveness.

Brand popularity plays a role as well. A well-known and trusted brand often leads to a higher ROAS due to increased customer loyalty and recognition. Moreover, the type of advertising used, whether it’s social media, search engine, or influencer marketing, can impact ROAS differently.

Positive customer reviews also contribute positively to ROAS by building trust and confidence in the advertised product or service. Lastly, product pricing can affect ROAS, with lower-priced items often resulting in higher ROAS due to increased affordability and accessibility.

By taking these factors into account, marketers can better calculate ROAS and make informed decisions about their advertising strategies.

In brief, the factors that affect ROAS are:

  • Operating costs and profit margins
  • Market size and competition
  • Product or service quality
  • Pricing strategy
  • Ad quality
  • Audience segmentation
  • Brand popularity
  • Type of advertising
  • Customer reviews
  • Product pricing

ROAS mistakes

When diving into ROAS data, steering clear of common pitfalls can make all the difference.

First off, it’s crucial to grasp what ROAS truly represents. Unlike ROI, which measures total return on investment, ROAS zeroes in on revenue generated per advertising dollar spent. This distinction sets the stage for understanding its role in evaluating ad campaign effectiveness.

Yet, ROAS shouldn’t hog the spotlight alone. While it’s a key metric, sidelining other vital indicators like customer lifetime value (CLV), customer acquisition cost (CAC), and overall ROI paints an incomplete picture. Viewing these metrics holistically provides a deeper understanding of campaign performance and profitability over time.

Furthermore, fixating solely on ROAS risks overlooking broader growth opportunities. Incorporating factors like CLV ensures campaigns remain profitable and sustainable in the long run. Similarly, disregarding attribution models can muddy insights into how revenue aligns with different advertising channels, leading to misinformed decisions.

Budgeting also warrants attention. Insufficient budget allocation can hamstring campaign effectiveness. Adequate funding ensures campaigns have the resources needed to thrive and drive results.

Interpreting the ROAS ratio accurately is paramount. Understanding that a ROAS of 2:1 translates to $2 revenue for every advertising dollar spent offers clarity, while a 1:1 ratio signifies a break-even point.

Yet, context matters. ROAS should be scrutinized within the broader marketing strategy and business objectives. Considering factors like target audience, marketing channels, and product offerings contextualizes ROAS data for informed decision-making.

Quality data underpins reliable ROAS calculations. Ensuring data accuracy, completeness, and timeliness is vital for meaningful insights and actionable decisions.

Lastly, regular data reviews keep campaigns on track. Monitoring performance and adapting strategies based on real-time data optimizes campaigns for maximum ROI and long-term success.

In brief, the most common mistakes are:

  • Misunderstanding ROAS
  • Ignoring other important metrics
  • Focusing solely on ROAS
  • Not considering attribution models
  • Ignoring customer lifetime value (CLV)
  • Inadequate budgeting
  • Misinterpreting the ratio
  • Not considering the context
  • Ignoring data quality
  • Not reviewing data regularly

ROAS and attribution models

Understanding ROAS data isn’t just about crunching numbers—it’s about understanding how customers engage with your business at every step of their journey. That’s where attribution models come into play. These models help paint a clearer picture of which advertising campaigns and channels are making the biggest impact on your revenue.

By diving into attribution models, you can pinpoint exactly which touchpoints are driving conversions and revenue. This insight is invaluable for fine-tuning your marketing strategy and ensuring your budget is allocated effectively.

Now, there are different flavors of attribution models out there. You’ve got single-touch attribution, which gives all the credit to either the first or last interaction a customer had before making a purchase.

Then there’s multi-touch attribution, which spreads the credit across all touchpoints in the customer journey. Many PPC experts prefer multi-touch attribution for ROAS calculations because it provides a more holistic view of how your marketing efforts are paying off.

Which marketing metric is best for you?

In brief, the limitations of both metrics are the following:

  • Lack of actionability
  • Incomplete data
  • Limited focus on paid media
  • Lack of attribution
  • Limited to a single metric
  • Lack of consideration for customer lifetime value
  • Lack of consideration for revenue floor
  • Lack of consideration for costs
  • Lack of consideration for changing business objectives
  • Lack of consideration for the unique customer journey

MER and ROAS are both important metrics in evaluating the effectiveness of marketing campaigns, but they have different focuses and limitations.

MER (Media Efficiency Ratio) is a metric that measures the proportion of a company’s total marketing expenses to its revenue, providing insights into how much a company is spending on marketing relative to its overall revenue. It is calculated by dividing total revenue by total ad spend. MER is a holistic metric that looks at the total revenue for all marketing efforts, rather than a more granular view that can be less forgiving when certain campaigns don’t perform compared to others. It is particularly useful in evaluating the value of brand awareness activity over ROAS, which may not attribute revenue correctly to the initial touchpoint.

ROAS (Return on Ad Spend) is a metric that measures the efficiency of marketing no matter the time horizon. It is calculated by dividing the revenue generated by a specific ad campaign by the cost of that campaign. ROAS is a living, breathing performance metric that incorporates conversion lag and tracks revenue over time. It is particularly useful in evaluating the effectiveness of specific ad campaigns and making decisions about resource allocation.

However, both MER and ROAS have limitations. MER does not take into account all the necessary data points, such as product cost, shipping, taxes, and overhead expenses, which are essential for determining the profitability of a marketing campaign. ROAS does not take into account the revenue floor, which is the amount of revenue a company makes without marketing, and may not accurately reflect the impact of a marketing campaign on overall revenue growth. Additionally, both MER and ROAS lack actionability, meaning they don’t provide enough information for marketers to make meaningful decisions and improvements.

Therefore, it is recommended to use both MER and ROAS in conjunction with other metrics, such as customer lifetime value (LTV), revenue floor, and conversion lag (TTC), to get a more complete picture of marketing effectiveness and make informed decisions about resource allocation.
