Why Your Best Campaigns are Killing Your Growth: The M.O.P.* Playbook

*Margin Optimised Performance (Yes, we are dubbing it here first)

By Luke Hill, Senior Paid Media Manager, Launch

If you’re a CMO looking at your marketing dashboard today, the data likely looks impeccable. Your ROAS is holding at a healthy 5:1, your cost-per-click is stable, and your team is hitting its efficiency targets. On paper, you’re winning.But in the boardroom, the conversation feels different. Despite the efficient metrics, actual business revenue has hit a plateau.

At Launch, we’ve been asking: “What if ROAS is the wrong KPI altogether?”.

This is what we call the Performance Plateau—a trap many scaling e-commerce brands fall into when they mistake platform efficiency for business growth. As Luke Hill recently shared at HeroConf, if every campaign in your account looks perfectly efficient, you’ve likely stopped growing. You are simply squeezing the same demand harder rather than creating new growth. If you wait until you get closer to Q4 to address this, you will have lost your momentum.

Now is the time to address the plateau and start creating demand. This piece is based on a real (anonymised) example where we helped a client ditch ROAS in favour of a profit-led framework. The outcome? Higher margins, smarter spend, and a more resilient account heading into peak seasonality.

The why: ROAS is easy, but not honest

ROAS = revenue ÷ ad spend. Simple maths. But it doesn’t tell you:

• Whether you’ve made any actual profit
• How different product margins affect your bottom line
• If you’re optimising towards the right success metric
  

In short, ROAS might make your campaigns look good. But it won’t help you scale profitably.

Why efficient campaigns often starve the rest of the ecosystem

To understand why your best campaigns might be killing your growth, stop looking at spreadsheets and start looking at your garden. Scaling a business isn’t a maths problem, it’s an environmental one.

I’ve recently moved house and, inspired by Clarkson’s Farm, started growing small scale crops including a favourite chili I’d dubbed Richard Ham. Poor Rich was struggling, and if I followed typical performance logic I would simply have stopped watering it.

But when I thought about it, there was more at play, just as there is with struggling performance campaigns:

1. Water (Your Budget & Efficiency)
   Water is the resource we all obsess over. In PPC terms, this is your spend, your CPCs, and your ROAS. It’s easy to measure, so most managers optimise for it until their ‘plants’ are drowning. But here is the hard truth: you can keep watering your best plants all you like, but you will eventually kill them if you don’t provide anything else.
2. Sunlight (Your Profit Signals)
   Sunlight represents Profit. In the same way a plant cannot grow without light, a business cannot scale without margin. Growth comes from making sure the right products – the high-margin ‘sun-seekers’ – are getting enough light. If you only focus on water (efficiency), the platform algorithm will naturally gravitate toward what is easy to sell, even if those products are low-margin and losing you money in the long run.
3. Soil (The Environment)
   The soil is the context your products sit in: your channels, your tracking, and your stock levels. If the soil is weak (e.g., broken tracking or stock titans going out of stock), no amount of water will fix it. You have to fix the environment before you can expect the campaign to thrive
   Taking it back to Richard Ham, rather than deserting it, I fixed the environment, stayed patient and gave it the right amount of time and sunlight. Today, Richard Ham is thriving.

DIscovery: asking “why” until it hurts

Our client — a major caravan accessories brand — came to us with a simple brief: “We need to hit a 5x ROAS.”

Our first question: Why 5x? (Thanks, Taiichi Ohno of Toyota Motor Corporation.)

After a few more rounds of “Why?”, the answer emerged: “Because that’s when we’re profitable.”

And there it was. The real KPI wasn’t ROAS — it was net profit.

They weren’t alone. Many brands default to ROAS because it’s easy to track and compare. But ROAS is just a proxy — and often a poor one — for what really matters to the business.

Requirements and challenges

This client had:

• Over 2,600 SKUs in their feed
• Varying margins across product categories
• An overly broad account structure with “catch-all” campaigns
• Internal pressures to show month-on-month improvement

On top of this, they were allocating budget based on surface-level efficiency, not true profitability.

The journey: profit-first restructuring

Here’s what we did:

1. Segmentation by margin
   We worked with the client to group products in tiers according to their profit margin:
   • Low (10–20%)
   • Medium (20–30%)
   • High (30%+)
   This allowed us to set performance expectations based on profitability, not arbitrary ROAS goals.
2. Custom feed labels and exclusions
   We introduced advanced custom label structures, including product status, ROAS, margin and tightly knit categories. These margin-based labels in the product feed allowed us to implement auto-exclusions for low-margin, low-ROAS SKUS. No more wasted spend. Alongside structuring campaigns by margin to allow more room for lower ROAS targets in higher margin campaigns = more profit.
3. New KPI: towing in the green
   We built a custom metric to track average margin and net profit estimates across campaigns — giving us a better picture of real-time account health.
4. Smarter budget allocation
   By shifting to a margin-based build, it allowed us to push budget at high margin campaigns with better net profit, thus improving efficiency without increasing spend.
   

The results: profit over performance

June (old structure):

• ROAS: 4.64

July 24 (New Structure):

• ROAS: 5.1
• Budget increase: just 40%

August 24:

• Budget down 19%
• Net profit barely moved, proving account efficiency had skyrocketed

September:

• Budget down 37%
• Revenue only down 23%
• ROAS jumped to 8.83

Despite spending less, the account kept delivering more bang per buck — the clearest sign that a profit-led approach was working.

Green dashboards can hide red flags

Revenue is a vanity metric; profit is the reality. During our restructuring for the caravan brand, we hit a moment that proved this perfectly.

Between March and April revenue jumped by 21%. Despite the revenue spike, the account actually delivered less profit.

Without the M.O.P. framework in place, we would have celebrated that revenue growth. Instead, because we were tracking margin, we caught the dip, adjusted our bidding, and increased POAS (Profit Over Ad Spend) by 18.6% the following month.

What This Means for CMOs

This isn’t about one brand. This is about a broader industry problem: we’ve been using the wrong metrics to measure success.

ROAS is only useful if your margins are flat and your costs are simple, which they rarely are. Moving to a net profit-based framework gives your team a smarter way to grow accounts, especially in volatile markets.

How to transition to a profit-led performance marketing model

Transitioning to a profit-led model requires the right tools to handle complex data. Here are my recommendations:

1. Feed Management: Use tools like Shoptimise or Data Feedwatch to create automated rules. My preference is Shoptimise for its ability to run performance rules that connect directly to Google Ads.
2. Custom Labels: Map out your Cost of Goods Sold (COGS) to create ‘Margin Buckets’ (Low, Mid, High) within your feed.
3. POAS (Profit Over Ad Spend): Move your reporting toward this metric to align your marketing spend with your P&L.`
   

One key takeaway:

Stop optimising for ROAS. Start optimising for profit.

You’ll not only make better decisions, you’ll build stronger cases for budget increases and long-term investment.

It’s time to grab that M.O.P and clean up that misleading data.

What to work with your performance marketing agency on next:

• Reviewing product feeds — are your campaigns grouped by margin?
• Identify SKUs with high volume but poor profitability — could they be dragging your ROAS down?
• Consider introducing a profit-based KPI like “Towing in the Green” to your reporting dashboard.
