Here's a confession: I've sat in boardrooms where everyone high-fived over a 6x ROAS, only to watch the same company flatline on revenue six months later. It's the marketing equivalent of celebrating your heart rate monitor while losing the marathon.
Look, I get it. ROAS is seductive. It's clean, it's quantifiable, and it makes CFOs nod approvingly during quarterly reviews. But after two decades of watching brands chase this metric like it's the Holy Grail, I've got to tell you something that might sting: ROAS is a measurement, not a strategy. And if you're treating it like one, you're probably leaving serious money on the table.
The Dashboard Delusion
Let me paint you a picture. You're running a B2B SaaS campaign. Your Google Ads dashboard shows a beautiful 5x ROAS. You spend $1, you make $5. Time to scale, right?
Not so fast.
As Permutive's Tom Shapland points out, ROAS is often used as a proxy for growth, but hitting a ROAS target isn't the same as actually driving growth. The metric tells you what happened in a narrow window – it doesn't tell you whether those conversions would have happened anyway, whether those customers will stick around, or whether you're actually expanding your market.
Here's the uncomfortable math: if your best-performing campaigns are all branded search and retargeting, you might be celebrating efficiency while your pipeline slowly starves. You're essentially paying to capture people who were already looking for you. That's not growth – that's an expensive toll booth on a road your customers were already driving down.
The 70% Problem Nobody Talks About
Want to know what really keeps me up at night? According to recent industry analysis, at least 70% of the open web is already operating without third-party cookies and IDs. That means when you're looking at your ROAS dashboard, you're potentially missing the vast majority of your prospective customers.
Think about that for a second. You're optimizing for a metric that only captures a fraction of your actual market opportunity. It's like judging a restaurant's success by only counting the customers who came in through the front door while ignoring the ones who walked in through the side entrance.
This isn't just a measurement challenge – it's a growth problem. Those invisible audiences represent your next wave of customers, the ones who could unlock real expansion. But if your entire strategy is built around optimizing ROAS on the audiences you can see, you're essentially playing defense while calling it offense.
The Triangulation Imperative
So what's the alternative? As QRY's strategic framework suggests, the smartest marketers are moving away from single-metric obsession toward what I'd call "triangulation" – using multiple lenses to understand what's actually happening.
Here's how I think about it:
Business Impact: What's your Marketing Efficiency Ratio (MER)? That's total revenue divided by total marketing spend. Unlike ROAS, MER doesn't care about attribution squabbles – it just tells you whether your overall marketing engine is sustainable.
Incrementality: How many of those conversions happened because of your ads versus with your ads? This is the question that separates sophisticated marketers from dashboard watchers. As Search Engine Land notes, if someone searches your exact brand name and clicks your ad instead of the organic result, you haven't gained anything – you've just paid for a conversion that was already on its way.
Efficiency: Yes, ROAS still matters here. But it's one input among many, not the final verdict.
The Lifetime Value Blind Spot
Here's where B2B marketers especially need to pay attention. As marketing strategist Drew Sanocki puts it, "ROAS is a lagging indicator of whether your strategy is working. It's not the strategy itself."
Consider two leads:
- Lead A comes through a branded search campaign with a 6x ROAS and churns after three months.
- Lead B comes through a cold prospecting campaign with a 2x ROAS but stays for three years.
If you're only looking at ROAS, you'll optimize for more Lead As. But Lead B might be worth ten times more to your business over their lifetime. The metric that looks efficient in the short term is actively sabotaging your long-term growth.
This is why I've started asking clients a different question: "What's your ROAS on customer lifetime value?" It's a harder calculation, but it's the one that actually matters.
The Full-Funnel Reality Check
One pattern I see constantly: brands only running bottom-funnel conversion campaigns because they deliver the highest immediate ROAS. It's like a restaurant that only serves people who walk in already hungry and ready to order. Sure, your conversion rate looks great, but you're ignoring everyone who doesn't know you exist yet.
Research from Marpipe confirms what I've observed anecdotally: the most effective teams don't choose between ROAS and broader metrics. They use ROAS for tactical decisions – pausing, scaling, optimizing campaigns day to day – while tracking MER to keep the company aligned on overall profitability.
Top-of-funnel awareness campaigns might show terrible immediate ROAS. But they build your audience and make all your other campaigns work better. When you run full-funnel campaigns, your blended ROAS might actually decrease in the short term. But your overall revenue, profit, and business value? Those tend to skyrocket.
The MER Lever
Here's the mental model I use with my team: think of MER as a growth lever, not a target.
- Higher MER = greater efficiency and profitability, but slower growth
- Lower MER = more aggressive investment, faster top-line growth, lower short-term profit
Neither is inherently better. The key is knowing which direction to lean based on your business goals, market conditions, and cash flow strategy. As QRY's framework suggests, adjusting MER lets you control how quickly you scale while maintaining healthy margins.
The Bottom Line
Look, I'm not saying throw your ROAS dashboards in the trash. The metric still has a place in your reporting stack. But it shouldn't be the only metric guiding your decisions – and it definitely shouldn't be confused with a strategy.
The brands I see winning in 2026 aren't chasing higher ROAS numbers. They're building smarter, more sustainable strategies focused on incrementality, lifetime value, and full-funnel thinking. They're asking harder questions: "Would this conversion have happened anyway? What's this customer worth over three years? Are we actually expanding our market or just harvesting existing demand?"
Data tells you the what, but brand tells you the why. And right now, too many marketers are drowning in the what while completely ignoring the why.
So the next time someone celebrates a record ROAS in your marketing meeting, ask the uncomfortable question: "That's great – but are we actually growing?" The answer might surprise you.
