How is it Different from other Conversion Metrics?

With countless marketing metrics and a dizzying array of acronyms, it’s easy to feel overwhelmed. Let’s clear up the clutter and understand how these metrics differ and complement each other.

Difference Between ROA and ROAS

ROAS (Return on Ad Spend) evaluates the revenue generated specifically from advertising efforts. On the other hand the ROI (Return on Investment) measures overall profitability by comparing net profit against total investment costs.

The ROAS formula in digital marketing is generally: ROI = (Net profit / net investment) x 100

ROAS helps advertisers and marketers assess the efficiency of marketing campaigns by calculating the money earned compared to the ad spend.  

One key distinction is that a campaign can show a negative ROI yet still deliver a positive ROAS. This occurs when the overall investment exceeds profit, but the return from advertising campaigns is positive based on the calculation method.

ROAS vs CAC

Customer Acquisition Cost (CAC) is determined by dividing your overall marketing expenditure by the total number of customers acquired during a specific campaign or time period.

For example, spending $2,000 on a marketing campaign that brings in 200 new customers results in a Customer Acquisition Cost (CAC) of $10 per customer.

While both CAC and ROAS evaluate the effectiveness of your marketing spend, they highlight different outcomes—CAC focuses on the cost to acquire each customer, whereas ROAS measures the total revenue those customers generate.

By analyzing ROAS, you can determine if you’re acquiring valuable customers and allocate your efforts accordingly.

ROAS vs. eCPA

Effective Cost Per Action (eCPA) calculates how much you’re spending to drive a specific user action—like a click, sign-up, or purchase. For example, if a $1,000 advertising campaign generates 200 actions, your eCPA would be $5 per action.

While both ROAS (Return on Ad Spend) and eCPA evaluate campaign performance, they focus on different aspects. While eCPA focuses on how efficiently your campaign drives specific user actions, ROAS evaluates the total revenue those actions generate.

For instance, if 200 clicks from a $1,000 campaign result in $1,500 in sales, your ROAS would be 150%—calculated by dividing revenue by ad spend.

Both ROAS and eCPA are essential metrics for assessing campaign success. By tracking both, you can optimize your campaigns to achieve your desired goals

ROAS vs. CTR

Click-Through Rate (CTR) gauges how well an ad captures audience interest. It’s calculated by dividing total ad clicks by the number of impressions. The calculation reveals how frequently users interact with your advertisement.

While CTR indicates how well an ad performs in generating clicks, it doesn’t provide a complete picture of campaign success. ROAS, or Return on Ad Spend, offers a clear snapshot of advertising efficiency by showing how much revenue is generated for every dollar spent on ads.

In essence, CTR focuses on the ad’s ability to attract clicks, while ROAS assesses the overall profitability of the campaign.

How to Calculate ROAS in Marketing?

Return on Ad Spend (ROAS) is a crucial performance metric used to evaluate the efficiency of your advertising campaigns. It’s calculated with help of a simple formula:

ROAS = revenue attributable to ads/ad spend

For example, a $1,000 ad spend that generates $3,000 in revenue results in a ROAS of 3:1—signifying a $3 return for every dollar invested.

In the scenario above, the ROAS is calculated as 3:1, meaning you earn $3 in revenue for every $1 invested in advertising.

In the given scenario, the ROAS translates to a 3:1 ratio—reflecting that every ₹1 spent on ads yields ₹3 in return. You can also present it as a percentage by multiplying the ratio by 100, resulting in a 300% ROAS.

It must be noted that calculating ROAS isn’t always straightforward. Accurate ROAS measurement relies on clearly identifying and including all relevant advertising expenses in your cost calculations. You’ll need to decide whether to analyze spend on individual platforms or factor in additional expenses.

For example:

• Vendor costs Commissions from agencies or vendors working on the campaign.
• Team Costs: Includes salaries and compensation for in-house marketers or agency professionals responsible for managing and executing the ad campaign.

The definition of ad costs in ROAS calculation depends on the campaign type. Focusing on exact ad costs and creating a separate ROAS for total collateral ad expenditure provides visibility on overall performance and profitability for each campaign where ROAS is a key performance indicator.

I used a free ROAS calculator from AdRoll to estimate my advertising budget. The tool asked about my business, sales, and website traffic. I input conservative numbers for my tech site: 100 orders per month at $2,500 each, with 1,500 monthly visitors.

What Is A Good ROAS?

Although the ideal ROAS benchmark can differ by industry and campaign objectives, a common target is earning $4 for every $1 spent on advertising. However, platforms like Google Ads may yield lower averages depending on competition and ad type. Keep in mind, ROAS is just one piece of the puzzle. Understanding industry-specific ROAS benchmarks¹ and platform-level performance is key to optimizing your campaigns effectively.

ROAS Value	Revenue per ₹1 Spent	Performance Insight	Profitability
1:01	₹1	Break-even point. Just covering ad costs.	No profit or loss
2:01	₹2	Moderate return with limited profit margin.	Low Profit
2.5:1	₹2.50	Good returns showing effective ad spend.	Moderate Profit
3:01	₹3	Strong returns indicating high performance.	High Profit / Scalable

While a 4:1 ROAS is often cited as a general benchmark, it’s important to understand that expectations can vary significantly across industries. For instance, e-commerce businesses typically aim for a 4:1 ROAS, while retail may push for even higher at 5:1 due to thinner margins and high competition. In contrast, SaaS and B2B services often work with a 3:1 benchmark, balancing long sales cycles with recurring revenue models. Real estate campaigns, given their high-ticket value and longer decision-making processes, may consider a 2:1 ROAS acceptable. Always compare your ROAS against relevant industry standards to set realistic KPIs and optimize your ad strategy accordingly.

A lower ROAS—especially for awareness campaigns—doesn’t always signal failure; it may still drive valuable long-term brand growth. Always assess it alongside other key performance indicators.

What Are the Advantages and Limitations of ROAS?

Return on Ad Spend (ROAS) is a powerful metric for evaluating the financial impact of your advertising campaigns. It offers clear insights into how effectively your ad spend converts into revenue. However, while ROAS is valuable for optimizing marketing performance, it’s not without its drawbacks and must be interpreted in context.

Advantages of Using ROAS

ROAS (Return on Ad Spend) is a powerful tool for maximizing the impact of marketing campaigns. By measuring the revenue generated for every dollar spent on advertising, businesses can make data-driven decisions to optimize their efforts.

1️⃣ Channel Optimization

ROAS provides a clear picture of which marketing channels (email, social media, out-of-home, etc.) deliver the highest return. By focusing resources on top-performing channels, businesses can increase efficiency and allocate budget wisely.

2️⃣ Ad Performance Improvement

Comparing ROAS across different ad creatives helps identify the most effective elements (words, images, targeting). These insights enable businesses to refine their advertising strategy and boost overall performance.

3️⃣ Simplified Reporting

ROAS offers a straightforward way to assess advertising effectiveness, making it easy to communicate campaign results to both marketing and non-marketing teams. Its simplicity facilitates quick decision-making and budget allocation.

4️⃣ Data-Driven Decision Making

ROAS provides valuable data to inform future marketing strategies. By understanding which campaigns drive the best results, businesses can make more informed decisions, reduce wasted spending, and achieve faster results.

Limitations of Using ROAS

While ROAS is a valuable metric, it’s essential to recognize its limitations. This performance indicator is not a universal solution and can provide a skewed view of campaign effectiveness if used in isolation.

1️⃣ Short-term Focus 

ROAS primarily measures short-term ad performance by linking specific ad activity to immediate revenue. This perspective can overshadow the long-term value of customers, as represented by metrics like Customer Lifetime Value (LTV).

2️⃣ Limited Perspective 

Advertising is one piece of a broader marketing puzzle. ROAS fails to account for the cumulative impact of various marketing channels and touchpoints that influence customer decisions. Factors such as brand awareness, public relations, and word-of-mouthcan significantly impact sales without being reflected in ROAS.

3️⃣ Volume Overlooked 

A high ROAS might indicate a successful campaign, but it doesn’t necessarily mean a large customer base. A small number of high-value customers can inflate ROAS without providing a comprehensive picture of overall campaign performance.

Why is RoAS an important metric for all PPC campaigns?

Many of the big names among marketers and industry experts would come out loud and clear, telling people that RoAS is one of the most important metrics to get a sense of whether or not advertising efforts are working. Here’s why RoAS holds such importance:

1️⃣ Quantitative Insight into Campaign Effectiveness

ROAS delivers a clear, measurable insight into how much revenue your business earns for every dollar invested in advertising.

By calculating RoAS, marketers can precisely gauge how well their PPC campaigns are translating ad spending into actual revenue. This metric not only validates the efficiency of campaigns but also highlights areas where budget adjustments might be necessary.

2️⃣ Optimization and Budget Allocation

One of the key benefits of RoAS is its role in optimizing campaign performance RoAS indicates a profitable campaign, allowing marketers to invest more in successful strategies, while low RoAS signals the need for reevaluation and optimization. This dynamic approach helps in fine-tuning PPC campaigns to achieve better results and maximize ROI.

3️⃣ Strategic Decision-Making

RoAS serves as a critical tool for strategic decision-making. By analyzing RoAS, marketers can determine which channels and ad creatives are delivering the highest returns and strategically focus efforts on these areas. This data-driven approach ensures that marketing strategies are aligned with business objectives and financial goals.

4️⃣ Performance Benchmarking

Benchmarking performance against RoAS helps in setting realistic goals and expectations. By establishing a baseline RoAS, marketers can evaluate new campaigns against this standard, facilitating a more objective assessment of their effectiveness and potential for scaling.

5️⃣ Alignment with Business Objectives

RoAS is instrumental in ensuring that PPC efforts align with broader business objectives.By focusing on RoAS, marketers can ensure that their advertising spend is not only generating leads but also contributing to the bottom line, thereby supporting long-term business growth.

6️⃣ Enhanced ROI Measurement

Finally, RoAS is pivotal for measuring and enhancing the return on investment (ROI) from PPC campaigns. This metric is important for understanding the profitability of PPC campaigns and making data-driven decisions to improve ROI.

How ROAS Influences Marketing Strategies

Return on Ad Spend (ROAS) plays a pivotal role in shaping marketing strategies. It reveals to marketing professionals, which campaigns truly drive revenue and deserve further investment.

Here is how RoAS influences marketing strategies:

1️⃣ Campaign Optimization

• Identify High-Performing Channels: By comparing the ROAS of different marketing channels, businesses can allocate more budget to channels that yield higher returns.  
• Refine Ad Creative: Analyzing ROAS at the ad level helps determine which creatives resonate best with the target audience, leading to improved ad performance.  
• Adjust Bidding Strategies: ROAS data can inform bidding strategies, ensuring that ad spending is optimized for maximum return.

2️⃣ Budget Allocation

• Shifting Resources: Based on ROAS performance, businesses can reallocate budget from underperforming campaigns to those with higher potential.  
• Diversification: If ROAS is consistently high across multiple channels, it might be prudent to diversify the marketing mix to reduce risk.

3️⃣ Customer Acquisition Cost (CAC) Optimization

• Improving Efficiency: A high ROAS often indicates a lower CAC, meaning businesses are acquiring customers at a lower cost.
• Customer Lifetime Value (CLTV) Analysis: By correlating ROAS with CLTV, businesses can identify customer segments with the highest potential return.

4️⃣ Product or Service Optimization

• Product Performance: Low ROAS for specific products might indicate issues with pricing, product-market fit, or demand.
• Product Bundling: Analyzing ROAS can reveal opportunities for product bundling or cross-selling to increase revenue.

5️⃣ Target Audience Refinement

• Audience Segmentation: Comparing ROAS across different audience segments helps identify high-value customer groups.
• Persona Development: Understanding which customer segments generate the highest ROAS can inform the development of ideal customer personas.

Challenges in Using ROAS

Despite its usefulness, ROAS comes with several challenges. All marketers must navigate these in order to get a complete picture of campaign performance:

1️⃣ Data Accuracy and Completeness

• Attribution Challenges: Assigning credit to the right marketing touchpoints can be complex, especially in multi-channel campaigns.
• Data Gaps: Missing or inaccurate data can distort ROAS calculations.
• Delayed Conversions: Some conversions might occur days or weeks after ad exposure, making attribution difficult.

2️⃣ Short-Term Focus

• Long-Term Goals: Overemphasis on immediate ROAS can hinder long-term investments in brand building or customer loyalty.
• Ignoring Customer Lifetime Value: Focusing solely on initial purchases can undervalue repeat customers and referrals.

3️⃣ External Factors

• Economic Conditions: Fluctuations in the economy can impact sales and, consequently, ROAS.
• Seasonality: Product or service demand can vary seasonally, affecting ROAS.
• Rising competition: in the ad space can inflate bidding costs, ultimately reducing your overall ROAS and campaign profitability.

4️⃣ Complexity of Modern Marketing

• Multiple Channels: Calculating ROAS across various platforms (search, social, email, etc.) can be challenging.
• Cross-Device Behavior: Tracking user journeys across different devices complicates measurement.

5️⃣ Misinterpretation

• Overreliance: Using ROAS as the sole metric can lead to suboptimal decisions.
• Ignoring Other KPIs: Focusing solely on ROAS might neglect other important metrics like customer acquisition cost (CAC) or customer lifetime value (CLTV).

To overcome these challenges, you must use ROAS in conjunction with other metrics, implement robust data management practices, and consider the long-term implications of their campaigns.

What Metrics We Take to Improve Your ROAS?

A low Return on Ad Spend (ROAS) doesn’t necessarily spell disaster for your ad or marketing campaign. It might just mean your campaign—or your site or product—needs some fine-tuning.

Here are some strategies that we use to boost your ROAS:

Experiment with Ad Placement

If your ads are running on media or e-commerce sites, we try varying the placements. We test out banner ads versus landing pages, skins, or pop-ups. On social media, strategic ad placement makes a big difference.

Use Audience Targeting

We refine your target audience or apply hyper-local marketing techniques to increase conversions per dollar spent. Facebook allows us to target ads based on numerous audience parameters like location, age, relationship status, and interests. We customize ad content to resonate with targeted audience segments, ensuring higher relevance and engagement.

For instance, after researching AdRoll for this article, their ad now appears in my Facebook feed, clearly targeting users with relevant interests in hopes of catching potential leads closer to making a purchase.

Increase ROAS by Targeting Audience Interests

Google’s Local Campaigns can help highlight your products to potential customers nearby. Choosing the right platform for your ads is crucial—if your audience is younger, we consider Snapchat or TikTok over Facebook. For B2B brands, LinkedIn might be a better investment.

Refine Your Keywords

Bidding on broad or high-volume keywords often leads to higher costs with lower conversion efficiency, making them less effective for targeted campaigns.

Instead, focus on specific keywords relevant to your brand. For instance, if you own a pizza chain with vegan and gluten-free options,we target keywords like “cauliflower crust pizza” or “best vegan cheese pizza.” We use location-specific keywords for physical location. For example, instead of just “pizza shops in NYC,” we bid on keywords like “pizza shops in Forest Hills” or “pizza shops in Briarwood.”

Lower Your Ad Development Costs

Our process begins by analyzing your ROAS data to identify and cut out low-performing campaigns that drain budget without delivering results.

We focus your efforts and budget on campaigns that are delivering results. Refining your keywords and target audience can also help us save you money by concentrating your budget on more promising areas.

Utilize Target ROAS in Google

When setting up ad campaigns, Google offers the option to choose a target ROAS. Google will predict conversion rates based on your target ROAS and optimize your bids accordingly. We apply this target to individual campaigns or an entire portfolio.

We apply this target to individual campaigns or across a portfolio to maximize returns. According to Google Ads Help², Target ROAS bidding allows advertisers to achieve specific return goals through data-driven automation and campaign-specific adjustments.

By selecting Target ROAS, businesses let Google adjust bids in real-time using historical data and predictive algorithms—ensuring ads are shown where they’re most likely to yield high returns.

Investigate Issues Beyond Your Ads

A low ROAS might not always indicate a failed campaign. It could point to issues outside your ad strategy. If you’re seeing strong conversion rates but a low ROAS, it may indicate that your product pricing is too low to generate profitable returns. Conversely, if click-throughs are high but conversions are low, your pricing might be too high.

If users abandon their shopping carts, we consider whether your UX design is confusing. It could also be that your CTAs on landing pages are unclear, or users aren’t sure how to complete their purchase. In such cases, re-evaluating your UX could help.

A low ROAS is a signal to dig deeper into potential issues and refine your strategy.
