The Plain English Guide to Return on Ad Spend (ROAS)
As a marketer, one of your key responsibilities is to ensure that the money you invest in advertising ultimately pays off in revenue and profit. But with so many different metrics and acronyms floating around, it can be tricky to know exactly how to quantify your ads‘ financial impact.
That‘s where ROAS comes in. Return on ad spend is one of the most important profitability metrics for marketers to understand and track. In this comprehensive guide, we‘ll break down everything you need to know about ROAS in plain English – what it is, how to calculate it, what‘s considered a "good" ROAS, and proven strategies to boost yours.
By the end of this post, you‘ll be armed with the knowledge and tactics you need to make every advertising dollar work harder for your business. Let‘s dive in.
What Is Return on Ad Spend (ROAS)?
Return on ad spend (ROAS) is a marketing metric that measures the amount of revenue generated for every dollar spent on advertising. Essentially, it tells you the effectiveness of your advertising efforts in driving sales.
ROAS is expressed as a ratio. For example:
- A ROAS of 7:1 means that for every $1 spent on ads, $7 in revenue was generated.
- A ROAS of 2.5:1 means that for every $1 spent on ads, $2.50 in revenue was generated.
Calculating your ROAS allows you to compare the performance of different ad campaigns, channels, and creative assets to see which ones are delivering the best bang for your buck. This data empowers you to make informed decisions about where to invest your ad budget for maximum impact.
ROAS vs. ROI: What‘s the Difference?
If ROAS sounds familiar, you may be thinking of another "return" metric: return on investment, or ROI. While ROI and ROAS are similar, there are a few key differences marketers need to understand.
ROI measures the profitability of an investment relative to its total cost. It takes into account all expenses associated with the investment – not just the money spent, but also factors like employee salaries, vendor costs, and overhead.
In contrast, ROAS only measures the revenue generated in relation to a specific advertising investment. It doesn‘t factor in costs outside of the money spent on the ads themselves.
Here‘s a side-by-side comparison:
| Metric | Formula | Costs Included | Used For |
|---|---|---|---|
| Return on Investment (ROI) | (Revenue – Total Cost of Investment) / Total Cost of Investment | Ad spend, salaries, software, rent, etc. | Evaluating the overall profitability of a business, product, or initiative |
| Return on Ad Spend (ROAS) | Revenue / Cost of Ads | Money spent to buy ads | Measuring the effectiveness of specific advertising campaigns or channels |
So while ROI helps you assess the big-picture financial health of your marketing efforts, ROAS allows you to zero in on the performance of your advertising dollars.
Why Measuring ROAS Matters
Digital advertising budgets are ballooning. Worldwide digital ad spending hit $521 billion in 2023 and is forecasted to surpass $800 billion by 2026, according to eMarketer.
As more dollars flow into online advertising, it‘s never been more critical for marketers to understand their return on that investment. Tracking ROAS allows you to:
- Make data-driven decisions about budget allocation
- Identify top-performing campaigns, channels, and audiences
- Turn off underperforming ads before they waste spend
- Prove the tangible impact of your marketing efforts to leadership
- Improve the efficiency and profitability of your ad campaigns over time
Without insight into ROAS, you‘re essentially flying blind. Even if an ad campaign is generating a high volume of clicks or conversions, it‘s not truly successful unless the resulting revenue significantly outweighs the cost.
How to Calculate ROAS
On the surface, the formula for calculating ROAS is quite simple:
ROAS = Revenue / Cost of Ads
However, to ensure you‘re getting an accurate ROAS measurement, it‘s important to properly account for all the components of your "cost of ads." This should include:
- Media spend (the actual dollars spent to buy ad placements)
- Ad creative and production costs
- Affiliate commissions or revenue shares
- Advertising software/platform fees
- Agency costs
On the revenue side, tracking which sales originated from a specific ad campaign can be trickier – especially for businesses with longer sales cycles or offline conversions.
To connect the dots between a digital ad interaction and an eventual purchase, you‘ll likely need to lean on tools like Google Analytics and a CRM platform. Ecommerce companies can use trackable links with UTM parameters to monitor which website purchases came from a particular ad campaign.
For businesses with brick-and-mortar locations, tying digital ads to in-store sales requires additional strategies like unique promo codes, coupons, or surveys that ask customers where they heard about your brand.
Let‘s look at an example ROAS calculation:
Imagine your company spent $20,000 on a Google Search Ads campaign last month. That $20,000 includes $15,000 in media spend, $2,000 in ad creative and copywriting costs, and $3,000 in agency management fees.
The campaign drove $100,000 in directly attributable revenue. To calculate ROAS, you‘d divide $100,000 by $20,000 to get a 5:1 ratio. In other words, for every $1 you spent, you generated $5 in revenue.
One thing to keep in mind is that a customer‘s initial purchase doesn‘t represent their entire revenue potential. To get a true sense of your ads‘ long-term impact, it‘s wise to also calculate ROAS using customer lifetime value (CLV).
CLV is the total amount of money a customer is expected to spend on your products over the course of their relationship with you. Incorporating this metric into your ROAS equation gives you a more complete picture of advertising success.
What‘s a "Good" ROAS? Industry Benchmarks to Know
According to HubSpot‘s 2023 Marketing Industry Trends Report, the average return on ad spend varied significantly by channel:
| Channel | Average ROAS |
|---|---|
| Google Search | $7.95 |
| Google Display Network | $6.70 |
| $6.50 | |
| $5.50 | |
| $5.74 |
As a general rule of thumb, a ROAS higher than 4:1 is considered strong for most businesses. A 10:1 ratio is considered exceptional.
However, what constitutes a "good" ROAS will vary based on your profit margins, operating expenses, and overall business model. For instance, a company with low production costs and high markup may be very profitable with a 3:1 ROAS, while a business with tight margins may need a ROAS of 7:1 or more to stay in the black.
The key is to establish a baseline ROAS for your unique business, and then implement strategies to improve on that baseline over time. Even a small lift in ROAS – say from 4:1 to 5:1 – can translate to tens of thousands of dollars in additional profit.
5 Ways to Improve Your ROAS
So, what can you do to boost your ROAS and squeeze more revenue out of every ad dollar? Here are five expert strategies to try:
-
Get surgical with audience targeting. The more precisely you can target high-value prospects, the better your ROAS will be. Use tools like Facebook Ads Manager and Google Ads to build detailed buyer personas based on demographics, interests, behaviors and past purchases.
-
Embrace testing and experimentation. Constantly A/B test different ad copy, visuals, and offers to see which combinations generate the most bang for your buck. Just be sure to test one element at a time so you can link improvements to specific variables.
-
Optimize post-click landing pages. Getting a user to click your ad is only half the battle – the web page they land on plays a huge role in conversion rates. Ensure that your landing pages are mobile-friendly, aligned with the messaging of your ads, and designed to drive a singular conversion goal.
-
Leverage AI-powered ad tools. Many ad platforms now offer smart bidding algorithms that automatically adjust your bids in real-time based on the likelihood of conversion. By leaning on machine learning to optimize for the lowest cost per acquisition, you can significantly improve ROAS without constant hands-on management.
-
Reallocate budget to top performers. Perhaps the biggest benefit of tracking ROAS is the ability to quickly identify which campaigns and ad sets are outperforming the rest. Be nimble and proactive about shifting spend to these high-ROI opportunities, rather than sticking with an even allocation.
To see how these strategies play out in real life, let‘s look at an example from grill manufacturer Weber. By leveraging Facebook‘s value-based lookalike audiences and campaign budget optimization tools, Weber was able to increase its ROAS by 31% while lowering cost per acquisition by 68% – resulting in 2.7x more revenue compared to the prior year.
Advanced ROAS Analysis & Optimization
For marketers looking to take their ROAS tracking and optimization to the next level, cohort analysis and multi-touch attribution are two powerful techniques to explore.
Cohort Analysis
Cohort analysis involves breaking your customers out into groups based on shared characteristics, such as when they made their first purchase or which acquisition channel they came through. You can then track the ROAS and CLV of these groups over time.
This allows you to identify trends and opportunities that may not be apparent in your topline ROAS data. For instance, you may find that customers acquired through Instagram ads tend to have a higher lifetime value than those from the Google Display Network, even if the initial ROAS is similar.
Multi-Touch Attribution
The customer journey is rarely a straight line from ad click to purchase. A user may interact with multiple ads across multiple devices before converting.
Multi-touch attribution models aim to assign revenue credit to each of these touchpoints to paint a more holistic picture of your ads‘ influence. Common models include:
- Linear: Assigns equal credit to each touchpoint along the path to conversion
- Time Decay: Assigns more credit to touchpoints that occurred closer in time to the conversion
- Position-Based: Assigns 40% credit each to the first and last interaction, and 20% to the touchpoints in between
Tools like Google Analytics, Nielsen, and Adobe offer multi-touch attribution capabilities to help you understand the complex interplay between your advertising channels and campaigns.
Balancing ROAS With Other Key Metrics
While ROAS is undoubtedly a crucial advertising metric, it shouldn‘t be evaluated in isolation. To get a truly comprehensive view of your ads‘ performance, it‘s important to analyze ROAS alongside other indicators like:
- Cost Per Acquisition (CPA): How much are you spending to acquire a new customer?
- Click-Through Rate (CTR): What percentage of people who see your ad click on it?
- Conversion Rate: What percentage of ad clicks convert into a sale or lead?
- Average Order Value (AOV): How much is the average customer spending per transaction?
Looking at these metrics in tandem helps you pinpoint areas for improvement at each stage of the advertising funnel.
For instance, let‘s say your Facebook ads have an impressive 8:1 ROAS, but your CTR is well below benchmarks. That suggests that while the people who do click your ads are highly likely to buy, your ad creative may not be attention-grabbing enough to maximize your audience reach. You‘d want to focus on testing new ad formats and visuals to boost that CTR.
On the flip side, if your CTRs and conversion rates are strong but your ROAS is coming in under target, the issue may be with your audience targeting rather than the ads themselves. In that case, you‘d want to concentrate your efforts on narrowing in on that ideal customer persona.
The Future of Ad Measurement & Attribution
As consumer privacy regulations evolve and third-party cookies sunset, tracking the connection between ad interactions and conversions is becoming increasingly complex. Marketers need to stay ahead of the curve by prioritizing first-party data collection and exploring privacy-friendly measurement solutions.
Some key strategies to future-proof your ROAS tracking include:
- Building out robust customer profiles in your CRM to enable effective first-party audience targeting
- Leveraging server-side tracking solutions to capture conversion data without relying on browser cookies
- Investing in data clean rooms to enable secure data sharing and campaign measurement across platforms
- Testing cookieless attribution solutions like Google‘s Enhanced Conversions and Ads Data Hub
The marketers who can adapt their measurement approaches to keep pace with these industry shifts will be well-positioned to maximize their ROAS in the years to come.
Conclusion
Return on ad spend is a powerful metric for quantifying and optimizing the performance of your advertising efforts. By tracking and improving your ROAS, you can lower your customer acquisition costs, boost profitability, and make every marketing dollar work harder.
However, ROAS mastery doesn‘t happen overnight. It requires continuous monitoring, experimentation, and refinement to keep driving better results over time.
The most successful marketers are those who stay hungry and agile – constantly testing new strategies, adopting new technologies, and pivoting based on performance. They recognize that in the fast-paced world of digital advertising, stagnation is the enemy of growth.
So start tracking your ROAS, set ambitious goals, and don‘t be afraid to shake things up in pursuit of better returns. Your bottom line will thank you.
