Digital marketing is an ever-evolving landscape, with players like Meta leading the pack. The social media giant, boasting billions of users, continues to adapt its algorithms to stay at the forefront of the industry. As a performance marketer in 2023, mastering the ins and outs of Meta’s dynamic ad ecosystem is more than just beneficial—it’s crucial to optimizing your brand’s CPA (cost per acquisition) or ROAS (return on ad spend).
But let’s be honest. Even seasoned marketers can grapple with understanding the essential components influencing CPA or ROAS. Is it all about having a mind-boggling budget? Is it the frequency of the ads? Or is it the timing?
Well, here’s some good news—it’s not as complex as it may seem. By mastering three straightforward formulas, you can streamline your approach, save money, and get a competitive edge on Meta’s platform.
And today, we are diving right into it. Let’s demystify these formulas together and unveil their impact on your marketing strategy.
The Holy Trinity of Meta Advertising: APM, CPA, and ROAS
Years ago, when I was a newbie in user acquisition, I was floundering. Navigating through countless metrics, trying to make sense of all the jargon—it was overwhelming. I remember wishing someone would break it down for me, shed light on how these elements intertwine.
Understanding these three formulas—APM , CPA, and ROAS—can clear the fog, improve your testing plans, and ultimately propel your marketing success.
Formula 1: APM—The Groundwork of a Campaign’s Effectiveness
Let’s start with APM. It’s essentially about getting a holistic view of your campaign’s effectiveness.
When you’re running a campaign, you want to know how many users not only viewed your ad but also took the desired action—clicked on it, signed up, or made a purchase. This is where APM comes into play. It’s calculated by multiplying the click-through rate (CTR) by the conversion rate (CVR):
Action Rate = Click-Thru Rate (CTR) * Conversion Rate (CVR)APM = (Conversions/Impressions) * 1000
So, why does APM matter to Meta’s algorithm? Because it’s a critical measure of your ad’s relevancy. How this metric stacks up against others in the auction can make or break your campaign.
In Meta’s auction, the winning ad isn’t simply the one with the highest bid—it’s the one with the highest total value, a measure of how relevant the ad is to the end-user. This total value is calculated as:
Total Value = Advertiser Bid * Action Rate + Ad Quality
Here, ad quality encapsulates feedback from users—likes, comments, shares, x-outs, and so on.
Scaling action rate into APM provides a standard measure, helping compare campaigns of different scales. As APM is directly tied to the action rate, optimizing APM is your golden ticket to winning Meta’s auction.
Formula 2: CPA—The Art of Cost Efficiency
The next part of the trilogy is CPA. Remember, efficient marketing isn’t about spraying and praying—it’s about making every penny count.
Turning the action rate into APM, we get:
CPA (cost per acquisition) = CPM (cost per mille)/APM
Sounds simple, right? Yet, many marketers overlook this relationship. Understanding it opens up a whole new world of performance marketing evaluation.
In brand audits, we don’t merely identify underperformance and devise broad action plans. We get specific. Instead of vaguely saying, “We need to improve CPA,” we strategize, “We’ll enhance CPA by increasing the conversion rate while maintaining CPM and CTR.”
To optimize your CPA, you need to either decrease your CPM while holding APM steady, increase APM while keeping CPM stable, or skillfully perform a balancing act—decreasing CPM while increasing APM. It’s a nuanced dance of numbers that, when choreographed well, leads to excellent results.
This is where Meta’s strategies come into play. They’re working on increasing the volume of ads on the platform to decrease CPM while simultaneously improving the efficiency of the ad delivery environment, thereby enhancing APM.
By setting up internal monitoring to reflect CPM and its relationship with the components that build APM, you can quickly diagnose and act on how to improve your performance marketing.
Formula 3: ROAS—The Ultimate Performance Indicator
The final part of our trinity is ROAS. If APM is about the effectiveness of your campaign, and CPA about its cost-efficiency, ROAS is about its profitability. ROAS (return on ad spend) is the metric most often used by advertisers to measure the financial success of their campaigns.
You might be surprised to know that our trusty APM is also key to calculating ROAS:
ROAS = (APM * AOV) / CPM
Here, AOV is the average order value, or how much a customer purchases on average. The formula demonstrates that ROAS is directly influenced by how efficient your advertising is at closing a sale (APM), the size of a customer’s purchase (AOV), and the cost of displaying your ad (CPM).
Like the other formulas, this might appear complicated at first glance. However, as a marketer, you already know you can boost ROAS by increasing someone’s purchasing frequency when they see your ad (APM), elevating how much they buy (AOV), and/or lowering your ad cost (CPM).
Again, Meta’s focus on ad volume and ad efficiency can drive an increase in ROAS for advertisers on its platform. It’s essential to understand that CPA and ROAS are not two distinct concepts—they’re constructed from the same component parts. Consequently, plans that decrease CPM, increase APM, or do both simultaneously are beneficial for all performance marketing organizations.
Harnessing the Power of Meta’s Advertising Formulas
So, the next time you’re strategizing for a marketing campaign on Meta’s platforms, remember these three formulas. They’re not just numbers and symbols—they’re your roadmap to efficient and effective advertising.
APM, CPA, and ROAS—these are the tools you need to navigate Meta’s ad landscape, improve your strategies, and achieve marketing success. They help you understand what’s working and what’s not, pinpoint areas of improvement, and make data-driven decisions.
As marketers, our ultimate goal is not just to reach audiences but to engage them, inspire them, and convert them into loyal customers. With these formulas in your arsenal, you’re well-equipped to do just that.
