Understanding Marginal ROAS and How to Optimize Ad Spend

Cracking the code for profitable ads isn’t hard when you know how to use marginal ROAS.

Return on ad spend (ROAS) is a critical metric in digital advertising. It measures the revenue generated for every dollar spent on advertising. But when businesses are scaling campaigns or making decisions about incremental budget allocation, a more nuanced metric, marginal ROAS, becomes essential. Understanding marginal ROAS can unlock the key to optimizing ad spend and achieving better profitability.

In this blog, we’ll explore what marginal ROAS is, why it matters, and how to use it to make smarter advertising decisions.

Before moving further, let’s first understand how marginal ROAS is different from average ROAS and why it’s so important for smarter ad spending.

What is Marginal ROAS?

Marginal ROAS refers to the additional revenue generated by spending one more dollar (or unit of currency) on advertising. Unlike average ROAS, which looks at the overall efficiency of your ad spend, marginal ROAS zeroes in on the incremental return you get from increasing your budget.

For example:

  • Average ROAS: If you spend $1,000 on ads and generate $5,000 in revenue, your average ROAS is 5:1.
  • Marginal ROAS: If increasing your budget by $100 generates an additional $300 in revenue, the marginal ROAS for that increment is 3:1.

By focusing on marginal ROAS, advertisers can identify the point of diminishing returns, where spending more on ads no longer delivers proportional revenue growth.

Now that we know what marginal ROAS is, let’s explore why it plays a key role in making better budget decisions.

Why Marginal ROAS Matters

Understanding marginal ROAS is vital for making informed budget decisions. Here’s why:

  1. Efficient Budget Allocation
    Marginal ROAS helps determine which campaigns or channels are still driving profitable growth and which are approaching saturation.
  2. Avoiding Overspending
    By monitoring diminishing returns, you can prevent over-investing in campaigns that have hit their efficiency ceiling.
  3. Profit Maximization
    While high average ROAS looks great, businesses ultimately want to maximize profit. Marginal ROAS ensures you allocate your ad spend where it generates the greatest net profit.
  4. Scalable Growth
    Marginal ROAS insights allow you to scale campaigns sustainably, ensuring incremental spending adds real value.

To enhance your marginal ROAS, gaining an understanding of paid media campaigns and their role in your broader marketing strategy is a crucial effort.

Once you understand why marginal ROAS matters, the next step is figuring out how to calculate it in a practical way.

Calculating Marginal ROAS

Calculating marginal ROAS involves assessing the additional revenue generated from an incremental increase in ad spend. The formula is:

Marginal ROAS=(Incremental Revenue/Incremental Ad Spend)

Step-by-Step Guide

  1. Identify Incremental Revenue: Determine the revenue generated from the extra ad spend. This can be tracked through advanced analytics and attribution models.
  2. Determine Incremental Ad Spend: Calculate the additional amount spent on advertising for the specific campaign or channel.
  3. Apply the Marginal ROAS Formula: Divide the incremental revenue by the incremental ad spend to obtain the marginal ROAS.

Example:

  • Incremental Revenue: $5,000
  • Incremental Ad Spend: $1,000
  • Marginal ROAS: 5,000/1,000=5

This means that for every additional dollar spent on advertising, you earn five dollars in return.

To ensure accuracy in your calculations, consider UTM Parameters and Best Practices for Tracking Campaigns to monitor the performance of each ad effectively.

Understanding how to calculate marginal ROAS is crucial, but knowing the factors that influence it helps you take better control of your ad performance.

Factors Influencing Marginal ROAS

Several factors can impact your marginal ROAS, and understanding these can help you optimize your ad spending more effectively.

  1. Audience Saturation: Overexposing your ads to the same audience can lead to diminishing returns. Explore behavioral segmentation in marketing to ensure your ads reach new and engaged audiences.
  2. Ad Quality and Relevance: High-quality, relevant ads are more likely to convert, enhancing your marginal ROAS. Continuously optimize your ad creative to maintain engagement.
  3. Channel Efficiency: Different advertising platforms offer varying levels of effectiveness. Understanding programmatic advertising basics can help you choose the most efficient channels.
  4. Seasonality and Market Trends: Consumer behavior changes with seasons and market trends, affecting your marginal ROAS. Stay updated with real-time data streaming strategies to adapt quickly.
  5. Competitive: Increased competition can drive up costs and reduce your marginal ROAS. Implementing cross-channel attribution models can provide a clearer picture of your competitive standing.

Knowing how to calculate marginal ROAS is helpful, but using strategies to improve it can make a real difference in your ad performance.

Strategies to Optimize Marginal ROAS

Optimizing your marginal ROAS involves a combination of strategic planning, continuous monitoring, and data-driven decision-making. Here are some effective strategies to enhance your marginal ROAS:
