ROAS is a crucial metric for any online advertiser and is the online advertising equivalent of Return on Investment (ROI).

ROAS is often used to describe the profits attributable to, and made by, advertising campaigns. Ultimately, the goal of this cornerstone metric is simply to measure the effectiveness of your marketing campaign.

In this guide, we'll discuss why ROAS is essential for marketers to track and several strategies to improve it over time.

What is ROAS?

Return on ad spend is a marketing metric that measures the revenue earned by your business for every dollar spent on advertising. For all purposes and intents, ROAS is similar to ROI (Return on Investment). In this case, the money you are spending on digital advertising is an investment of which you're tracking the return.

In simplest terms, ROAS measures the effectiveness and profitability of your advertising efforts. The more effectively your ads connect with prospects, the more revenue you should expect to earn from every dollar invested in advertising.

If you’re so inclined, you could measure Return on Ad Spend at different levels within your Google Ads account: the ad group level, the campaign level, the account level, and so on. Provided you know your ad spend and revenue at every level, you can easily calculate ROAS.

ROAS and ROI are quite similar in that they help evaluate how well a particular campaign is performing. Although digital marketers might often use these terms interchangeably, the truth is that they are different.

ROI typically focuses on the overall success of your digital marketing efforts, and if often tied to an entire strategy. In the perspective of paid search ads, ROI measures the ad profit in relation to the cost. Usually, Return on Investment is a business-centric metric which helps you to better understand how ads contribute to your business’s bottom line.

ROAS, on the other hand, focuses on particular advertising campaigns, groups, or even keywords. The ad-centric metric usually measures the gross revenue generated based on every dollar you spend on ads. It specifically aids in understanding the effectiveness of a PPC or paid search ad campaign.

Why Understanding ROAS is Essential for Marketers

ROAS is arguably the best metric for helping a business understand how their PPC ad campaigns are performing. This metric also gives you the information you need to prioritize your campaign spending across your paid search campaigns.

For instance, let’s assume your business is running 5 different PPC ad campaigns simultaneously. You’re looking to boost your ad spend but aren’t sure which campaigns are offering the best results per dollar. ROAS will provide you with that answer, thereby letting you optimize your PPC budget by increasing your investment in the best performing ads.

Once the ROAS for every ad campaign is ready, you can see which campaigns are giving more value for money. And if you realize that some campaigns greatly outperform others, you might think about reallocating some of your ad campaign budget to campaigns that are performing well.

What’s great about ROAS is that it isn’t only good for ad campaigns. You could also use the metric to evaluate target keywords and ad groups as well. For instance, if you realize that your ROAS is higher for specific keywords that you’re targeting, you might want to create new PPC ad campaigns based on the highest performing keywords.

Calculating ROAS

Now that we’ve defined return on ad spend and why it’s such an important metric, let’s look at how to calculate it. Contrary to other marketing calculations, ROAS is fairly easy to calculate due to the simplicity of the formula. ROAS is simply the total campaign revenue divided by the advertising campaign costs.

ROAS calculation

Before putting the ROAS formula to work, you must first determine the component of your online advertisements you’d like to evaluate. After that, take the total revenue that the ad has generated and subtract the amount spent to run the ad, after which you’ll divide this value by your ad spend.

Many PPC channels like Google Ads or Facebook Ads make it easy for you to track conversions and sales for every ad. With this conversion and sales data at your disposal, you can put it into the ROAS formula in order to understand the return on ad spend.

What is a Good ROAS?

After calculating ROAS, you’ll probably wonder what a good benchmark for ROAS is? Well, the truth is that there isn’t a right answer for what good ROAS is. Usually, a good return on ad spend depends on the type of business, the industry, as well as the products it sells. However, there are a few guidelines for determining whether your business is achieving a good return on advertising spent.

Although ROAS doesn't necessarily try to explain the impact a specific campaign has on your ecommerce business or company, determining a good return on advertising spend for your campaigns requires you to consider several business-related factors.

First, you must think about your overall goals growth-wise, and your timespan for achieving the goals. However, your goal should not be to do “good enough” and an above-average return on advertising spend might not suffice. An acceptable ROAS is typically influenced by operating expenses, profit margins, and the general operating health of a company.

And while there isn’t a conclusively right answer for this question, a common ROAS benchmark is a ratio of 4:1, or $4 in revenue for $1 ad spend. New businesses operating at lower budgets might need higher margins, while ecommerce stores that are committed to growth can afford to spend more on advertising. A company will gauge its ROAS goal once it defines its budget as well as gets a firm idea about its budget margins.

Defining a good return on ad spend depends on whether you mean “good for the advertising campaign” or “good for a company or industry.” That said, a good ROAS should be at least in the range of 400–500% for most ad campaigns.

Tips for Improving Return on Advertising Spend

The only way to improve your ROAS is to increase your overall revenue or reduce ad spending by optimizing your ad performance. Increasing your revenue could require that you significantly increase prices or look for different vendors who will let you reduce your production costs. It could have nothing to do with your PPC campaigns!

And while we won’t be able to provide every detail about optimizing your ads, here’s an overview of what you can do to improve your ROAS.

1. Create Ads for a Mobile Audience

As you think about ROAS for your Google Ads or Facebook Ads, it is important to factor in your mobile audience.

Google research shows that there are currently more searches on mobile devices than desktops. Besides, close to 50% of consumers who perform a local search for a service or product will make a purchase in a day of performing the search. And since most local searches are done on mobile devices, it is crucial to have these users in mind as you create PPC ads.

2. Consider the User Journey

Virtually all aspects of paid search ads come back to your audience. Failure to think about the consumer as well as their position in the buyer’s journey means that you might miss out on profit maximization. And although most PPC ad journeys begin with a single click, you must carefully plan where a user goes next.

For instance, when creating your PPC ads, you want to ensure that you’re giving an offer relevant to the buyer you’re targeting. And this is where buyer personas come into play. Besides, there are chances that you’ll have more than a single buyer so think about how the ads will be perceived by the target audience.

Besides offering relevant offers based on your target buyer and their position in the buyer’s journey, you need to consider the messaging. PPC ad messaging must be consistent across all campaigns when it comes to tone and brand voice. However, the way you capture their attention and convince them to take a step forward depends on their behaviors and motivations as well as where they are in the consumer journey.

3. Watch Your Competitors

Just like any other marketing tactic or strategy, it pays to watch your competition. Are they running successful PPC ads? What is it that they are doing well? By evaluating their mistakes and successes, you can easily look for ways to bolster your own advertising campaigns. Although there isn’t a way to understand how the ads perform without approaching them, you can easily see the kind of ad content they are feeding to search engine users and look for ways to emulate. If you're running Facebook ads, it's easy to find exactly what ads your competitors are using.

4. Work Towards Improving Your Ads Quality Score

When talking about Google Ads, a higher Google quality score often means that your cost per click goes down and, as a result, your ad performance increases. These factors play a crucial role in the chances of search engine users seeing and clicking on your advertisements.

There can also be a correlation between quality score and lower cost per conversion, and lower ad campaign costs mean that you’ll enjoy a higher ROAS. Google often uses quality scores to determine an ad ranking, with a large part of your quality score formula revolving around the ad relevance.

To improve ad relevance, you could begin by structuring the campaigns into smaller, more targeted groups. Instead of a single ad group with all keywords, create ad groups that are specific and directly related to the keywords they have.

ROAS Pitfalls You Should Look Out For

Although focusing on improving ROAS can be helpful, approaching it from the wrong angle can be detrimental to your online advertising campaigns and business at large. Here are a few pitfalls to be aware of to keep your marketing efforts on track.

1. ROAS Doesn’t Apply to All Marketing Efforts

First off, remember that ROAS can’t be applied to all marketing efforts. For you to assess any marketing campaign using ROAS, its true cost needs to be concrete. For instance, since PPC advertisements usually have a well-defined budget, establishing the return on advertising spend for a PPC campaign requires that you simply divide revenue by cost. On the flip side, the actual cost of many marketing campaigns, for example social media marketing, can’t necessarily be determined on a campaign-by-campaign basis.

2. Ad Campaigns Don’t All Contribute Directly to Sales

Here, we will focus on the ROAS formula’s numerator. As you probably know, not every marketing effort will translate to a conversion, and many initiatives are not meant to do so as well. Some initiatives – like newsletters and blog posts – are supposed to capture the attention of the target audience and get them to engage more with a brand. Others, like testimonials and customer reviews are deal-closers.

In simple terms, it wouldn’t make sense to evaluate the return on ad spend of any top-of-the-funnel marketing effort. Although these initiatives can play a crucial role in the customer’s buying decision, since the aim isn’t to make a direct sale, there isn’t sufficient reason to bring in ROAS when assessing the overall campaign’s effectiveness.

The Takeaway

Solely relying on ROAS metrics could be misleading. The value of ROAS to any business often depends on the goals of the advertising campaign, conversion factors, and what’s being spent. Some campaigns can provide a high ROAS but the company might still end up losing money due to other costs aside from advertising.

ROAS is calculated by considering the cost of advertising, so any other factors that could be eating into your profits might not be factored in.

All the same, ROAS can be extremely helpful for a business when used properly. It can help determine whether the ad campaign, ad group, or keyword is profitable, as well as provide key information about which campaigns you should be allocating more budget to.

If you're interested in tracking ROAS for clients, you can largely automate the process with our PPC dashboard or PPC reporting template.
