Today we’re talking about ROI in marketing. Not the sexiest acronym, sure, but it’s the one your CFO actually cares about. You can make the prettiest campaign in the world, but if it doesn’t move the revenue needle, well, it’s just a very expensive mood board.
So, what is ROI, really?
Let’s start with the basics. ROI, or Return on Investment, is how marketers measure whether their work is actually worth the money. It’s the ratio of what you got back compared to what you spent. That’s it. Simple in theory, slightly messier in practice.
Here’s the classic formula:
Marketing ROI = (Revenue Attributable to Marketing – Marketing Cost) / Marketing Cost
Say you spent $25,000 on a campaign and it brought in $100,000 in revenue. That’s a 3.0 ROI, or 300 percent. In other words, every dollar spent returned three. Not bad; that’s the kind of math that gets your budget approved next quarter.
But ROI does more than just pat you on the back; it does a few heavy-lifting jobs behind the scenes.
Why marketers keep obsessing over ROI
First up, it keeps your budget honest. When you know which channels are pulling their weight, you can stop throwing money at the ones that aren’t. That’s not just smart; it’s survival, especially when budgets get tight.
Second, it gives you ammo for the next exec meeting. ROI turns marketing from a fuzzy creative cost into a revenue engine. You’re not making content; you’re building value that pays off.
Third, it helps you steer the ship. Looking at ROI across different campaigns shows you what’s working, what’s not, and where to go next. It’s like GPS for decision-making, minus the passive-aggressive “recalculating.”
Still, measuring ROI isn’t always as clean as the formula makes it sound.
Where it gets messy: attribution, timing, and data chaos
Let’s start with attribution. That’s just a fancy word for “who gets credit.” And it’s a minefield. Do you give credit to the first ad someone saw? The last? Every touchpoint equally? Different attribution models give different answers, and none are perfect. According to Gartner, only 54 percent of marketers even trust their own attribution models. That’s… not great.
Then there’s timing. Some marketing efforts, like SEO or brand awareness campaigns, don’t pay off right away. If you only look at short-term ROI, you might kill something that’s quietly building long-term value. McKinsey points out that brand equity often gets ignored in these calculations, even though it’s one of the biggest long-term drivers of growth.
And of course, there’s the data problem. Your CRM says one thing, your ad platform says another, and your analytics tool is just quietly weeping in the corner. When your data is scattered across platforms, it’s hard to get a clear picture. Connecting the dots takes work; without it, ROI becomes more guesswork than metric.
So what do the pros do?
They get smarter about how they measure impact. ROI purists might cling to the basic formula, but advanced marketers layer in a few more tools.
Start with Customer Lifetime Value, or CLV. Instead of just measuring what a customer brings in right now, CLV looks at what they’ll bring in over time. That’s crucial if you’re running a subscription model or selling something people buy again and again. It shifts the focus from quick wins to long-term relationships. Which, let’s be honest, is how actual businesses grow.
Then there’s incrementality testing. This one’s for the nerds, and I say that with admiration. It’s about figuring out what marketing actually caused, not just what happened after it. Meta (yes, Facebook) swears by it. They run A/B tests and geo-lift studies to see what happens when one group sees an ad and another doesn’t. The difference between the two? That’s your true impact.
And finally, Marketing Mix Modeling. This one’s a bit of a mouthful, but it’s basically a statistical way to figure out which inputs (TV, digital, pricing, seasonality) drive sales over time. Google has tools for this, and big brands use it to measure everything from Super Bowl ads to email drip campaigns. It’s not fast, but it’s thorough.
What’s a “good” ROI, anyway?
That depends. According to Nielsen’s 2023 report, digital channels return about 2.6 times their cost, while traditional ones like TV come in around 1.7. So if you’re getting 3x from paid search, you’re doing better than average. If you’re getting 0.5x from print ads, well, maybe it’s time to stop pretending anyone reads those anymore.
Here’s the thing.
ROI isn’t just a spreadsheet number. It’s a story about how your marketing connects to revenue. And sure, telling that story well takes clean data, good attribution, and a little statistical finesse. But the payoff? You get to make smarter decisions, spend money where it matters, and, most importantly, prove that marketing isn’t fluff; it’s fuel.
And if that doesn’t make you want to calculate your ROI, I don’t know what will.
That’s the breakdown.
We’ll be back with more.
Until then, keep building.
