Why Paid Media Is the Backbone of Modern Digital Marketing

Paid media is now the core engine behind fast growth and visibility for brands. Whether your business is new or already established, digital marketing is too competitive to rely on organic progress alone. Paid media lets you put your brand in front of the right people, on the right platforms, at the right time.

Here’s the simple truth: Companies investing in paid media see faster results. You can target specific audiences, test and scale creative ideas, and get new customers—all with measurable results. As a digital marketing agency, we’ve watched businesses double or triple their revenue after launching campaigns built on data and performance. No guesswork. Just proof that paid media works.

What Makes an Agency One of the Best Paid Media Agencies

Top paid media agencies do more than run ads. They combine technology, creativity, and proven strategy to build lasting growth for their clients. The best agencies know how to match digital marketing tactics to each client’s goals and industry.

Why does that matter? Because not every campaign or client is alike. An eCommerce clothing brand needs something different from a B2B SaaS company. The best paid media agencies understand this—they customize everything, from ad copy to budget splits, based on your business.

From my experience at Hunter Digital, successful paid media comes down to six main strengths:

  • Integrated creative and media buying—so your ads not only look good, they actually convert.
  • Access to beta ad features and exclusive partnerships with Google, Meta, TikTok, Pinterest, and more.
  • Proprietary analytics platforms for real-time insights and quick pivots when results change.
  • A proven track record of real, measurable ROI.
  • Custom strategies for each industry.
  • Transparent reporting and reliable communication.

Agencies praised on industry lists—like these top-rated paid media shops—all share those traits.

Categories of Paid Media Agencies and Why Specialization Matters

Answer first: Not all paid media agencies offer the same thing, & choosing one with experience in your industry can cut your learning curve in half.

Specializations you’ll find in the market:

  • Enterprise and Fortune 500: Focus on complex, cross-channel buys and advanced analytics. Key for big budgets and global brands.
  • SaaS and Performance Marketing: Optimize long sales cycles, lead generation, and audience nurturing with laser-targeted search engine marketing and multi-step retargeting.
  • eCommerce and Direct Response: Maximize every ad dollar to boost sales, lower CPA, and unlock paid social and Google Shopping tactics.
  • Creator Campaigns: Pair brands with trusted influencers, perfect for Gen Z and those who want authenticity at scale.

At Hunter Digital, we’ve worked with clients across these categories. But no matter the industry, our approach is always data-first and growth-focused. If the numbers aren’t moving up, we’re not finished.

The estimated digital ad spending in the US will be around $190 billion in 2021, a 25% growth from last year. Although ecommerce brands are diversifying their acquisition channels, ads (mainly on FB, IG, TikTok, and Snapchat) remain the top channel.

And, the best metrics to figure out whether an ad is working? Return on ad spend.

That’s right – ROAS can help you figure out answers to burning questions like

  • How do you find out the cost of paid traffic?
  • How much revenue is generated from every penny that you shell out to get shoppers to your website?
  • What is the first metric that marketers measure to define the success of an ecommerce ad campaign?
  • Goes without saying, you need to keep a close eye on your return on ad spend, but that’s only a part of the larger picture.

Digital ad spending is rising at a steady pace. As a result of this heightened competition, few retailers witnessed an increase in their online ad costs by 89%. If you notice that your ROAS is dropping, this could be one of the contributing factors.

When it comes to budget planning and ecommerce strategy, ROAS is often viewed as a north star metric (a myth we later debunk). That shouldn’t be the case as ROAS is not equipped to handle these areas.

As a marketer, you are always looking to positively influence the behavior of consumers. ROAS falls short here and does not help you gauge if consumer behavior has changed in the first place.

In this blog, we are going to take a closer look at

  • what ROAS is,
  • what is a good ROAS,
  • how it is different from ROI,
  • why ROAS isn’t the ultimate metric
  • and how to accurately measure ecom success

Unfolding the concept of ROAS for ecommerce stores

Return on Ad Spend (or as we lovingly called ROAS) is a marketing metric that evaluates how effective an advertising campaign or strategy is. ROAS is a key metric that lets you know if your marketing channels are worth the investment or not.

The metric can also be used to compare one marketing campaign with another to help you identify which one of them is performing better.

The ROAS calculation is fairly simple. All you have to do is divide your ad campaign’s total revenue by the total cost incurred on it.

ROAS = Revenue/Cost
For example, if a clothing line spends $ 20,000 on a Facebook Ad campaign and generates $80,000 in revenue.

ROAS = 80,000 / 20,000 = 4:1, which simply means that for every dollar spent on the campaign, $4 was generated as revenue.

The ROAS calculated for a single channel like a Facebook Ad campaign is known as single channel ROAS.

But, if you want to know how all of your paid channels have performed you will need to calculate the blended ROAS.

In this ROAS calculation, you take into account total revenue earned from all your paid channels like Facebook, Google, or Snapchat and divide it by the total ad spends incurred on those channels.

The formula for blended ROAS is pretty straightforward.

Blended ROAS = Total paid revenue / Total ad spend

What counts as a good ROAS?

It is not easy to define what a good ROAS is. For some a ratio of 4:1 is brilliant, for others, it might indicate failure.

There are a few factors to consider to determine what a good ROAS is. They are:

  • Your profit margins
  • The industry you belong to
  • The average cost per click


Most companies aim to achieve a ratio of 4:1. However, the average ROAS is around 2:1 which means you make $2 in revenue earned for every $1 spent in Ad costs.

While startups may need a higher ROAS to cover costs and achieve financial growth, established companies can survive if the ROAS is low.

ROAS vs ROI

There are quite a few ways in which ROAS differs from ROI. Before we take a look at the differences, let’s understand what ROI is. ROI stands for return on investment. It is a metric used to determine the total profits made from investments.

A business needs to track both these metrics. The ROAS lets you know if a campaign has been successful in creating clicks, impressions, and revenue. What the ROAS fails to reveal is whether your paid ads department is profitable for the company. This is where ROI steps into the picture.

The importance of ROAS for ecommerce


Not sold on how ROAS can be an important metric for your online business? Here is why you need to keep track of this metric:

  • It monitors the average performance and returns on your ad campaigns
  • You will obtain accurate data to support changes in the campaign budget or an increase in ad spends
  • It will help you identify which campaigns are performing well and which are not
  • Advertising is often the most expensive component of an ecommerce strategy. If a campaign isn’t doing well, your marketing team needs to know that quickly and ROAS gives you that information

ROAS isn’t the ultimate metric (and why)

Here’s the thing: I know multiple agencies and in-house marketers reported on ROAS as their primary metric. Now, this was fine as long as attribution was alright.

However, now the variations in reporting are so large that the metrics are causing a misdiagnosis of true channel health. This leads to the inefficient deployment of spending, causing even further performance degradation to the ecosystem.

Attribution is broken (and will be so in the foreseeable future).

Also, ROAS cannot be used for fixing budgets either; especially when you have promotional events or a sale underway. During a sale, most of the people you target will find your product affordable and will click through your ads. ROAS calculation done in this case will be inaccurate.

ROAS is important but if it is the only metric you calculate, the results will be misleading. The ROAS calculation only takes into account the advertising costs but there are many other expenses that a business incurs like shipping, storage, production & maintenance. You need to optimize every area of your business to make a profit.

That is why you need to calculate it alongside other important ecommerce metrics like cost per click, ROI, and AOV.

The (new) three types of ROAS and why you should care

Once Triple Whale went through inordinate amounts of data from a kaleidoscope of Shopify stores and millions of dollars of ad spend, we identified a new growth formula:

Ecom Success = ncROAS x eROAS x POAS
Let’s look at each of these ROAS types and understand why they’re the right choice in 2022 to measure ecom success.

eROAS or MER

eROAS or Ecosystem ROAS is more popularly known as MER (marketing efficiency ratio). It gives you an indication of how successful your marketing ecosystem is. It shows you how effective your ad dollars are.

eROAS = Total revenue / Total ad spends
With eROAS you can approach the head of finance or the CFO of your company to understand how much money can be spent to earn X amount in revenue.

If they say you can spend up to $50,000 a month and earn a revenue of $250,000, you will know that your eROAS target is 5 [eROAS = Total revenue ÷ Total ad spends = 250,000 ÷ 50,000 = 5]. If your eROAS dips below 5, you have overspent, above 5 and you are underspent.

ncROAS

New customer ROAS shows you how efficient your marketing efforts are in generating revenue from new customers.

ncROAS = New customer revenue / Total ad spend
If your new customer ROAS is diminishing you are not successfully adding customers to your business.

Profit on Ad Spend or POAS

POAS indicates the total profits generated from the existing marketing efforts.

POAS = Gross profit / Total Ad spends
This ROAS calculation is going to tell you if you are driving the right products. It helps you understand if you are allotting ad spending for the right products to drive profitability for you or your clients’ business.

Tools to track the ROAS on your store

Let’s get to the most important part now. We are going to give you the two best possible ways to track the ROAS. Here they are

  1. The old-school way of using a spreadsheet
    This is the standard way of computing the ROAS where you add all the figures to a spreadsheet and obtain the result using formulae in a spreadsheet.
  2. Using Triple Whale
    Triple Whale is the #1 ecommerce analytics platform that centralizes important metrics like all three types of ROAS, net profit, AOV, email marketing sales, and a lot more.

That’s not all – you get to see all the metrics in one clean dashboard, send daily reports to your email/slack channel, or simply check out the health of your store right from your mobile app.

ROAS all the way!

There are a lot of strategies to improve this metric. Lowering your ad spend and reviewing your ad campaigns are ways to improve the ROAS. Optimizing landing pages, using the right keywords, and including a strong CTA are other tactics known to improve ROAS

Once you start tracking this metric you will know how effective your marketing efforts are. Take time to look at how you can get the best return on your investment through the ROAS calculation.
