Performance Max (PMax) campaigns seem like a dream come true for media buyers—a way to effortlessly run ads across all of Google’s channels. But if you’re serious about scaling businesses and driving real growth, you’ve probably noticed that PMax often doesn’t deliver when it comes to new customer acquisition and profitability.
I’m not here to tell you PMax is bad. It has its place, but if you’re relying on it to drive expansion, you’re likely leaving a lot on the table. In this post, I’ll break down why profitability matters more than platform-reported metrics and how you can educate your clients while reclaiming control of your campaigns.
1. Educate Before You Disrupt: Build Trust by Setting Expectations One thing I’ve learned over the years is that clients don’t always understand what real success looks like. It’s our job to teach them. Before making disruptive changes—like swapping PMax for standard shopping campaigns—you need to set clear expectations and educate them on what really matters.
Metrics like ROAS or in-app attribution often look impressive but can be dangerously misleading. What actually drives business success is topline KPIs like net profit and lifetime customer value (LTV).
Pro Tip: Always establish a shared understanding with your client before launching any test. Make it clear that platform-reported ROAS isn’t the ultimate goal—profitability is.
2. PMax Captures Demand—It Doesn’t Create It PMax is great at demand capture, but when you’re trying to create new demand and expand into untapped markets, it’s not your best bet. I’ve seen this firsthand. We ran a YouTube campaign for a tea infuser company that generated $500,000 in 60 days with just one video. Could PMax have done that? Maybe, but probably not as effectively.
Key Insight: Use PMax to capture demand once it’s been created through top-of-funnel channels like YouTube and Meta Ads. Don’t rely on it for expansion.
3. Measure What Actually Matters: Profitability Over Platform Metrics Here’s a story I love to share because it perfectly illustrates the point. I hired a Meta agency to run ads for one of my companies. I didn’t care about in-app ROAS or how many conversions they reported. I only cared about one thing: did my net profit increase?
Turns out, despite a reported ROAS that looked great on paper, our profitability took a $20,000 hit. So, we fired them. Why? Because I don’t care if an in-app metric says 10x ROAS if my business is losing money.
Actionable Advice:
- Forget vanity metrics—track profitability and cash flow.
- Regularly review your client’s P&L and bank statements.
- Be willing to pivot quickly if something isn’t working.
4. Don’t Let AI Commoditize Your Agency: Add Real Value Let’s face it—if your entire pitch is “We’ll set up PMax for you,” you’re setting yourself up to be replaced by automation. AI is getting better every day, and if all you’re doing is managing automated campaigns, clients will eventually wonder why they need you at all.
The solution? Add value where AI can’t. Be the strategist who understands cross-channel orchestration, creative development, and business metrics. That’s how you stay indispensable.
Key Takeaway: Your job is to deliver measurable business growth, not just manage campaigns. Focus on strategy, creativity, and financial outcomes.
5. Rethink Expansion: Go Back to What Works Sometimes, the best strategy is to go back to basics. Before PMax existed, we grew businesses with targeted YouTube and Meta campaigns. That hasn’t changed. These channels still work—often better than PMax—when it comes to generating new demand and driving profitability.
Final Thought: PMax isn’t a magic bullet. It’s a tool—one that should be used in the right context. When you focus on educating clients, tracking real business metrics, and leveraging the right channels for the right goals, you build campaigns that actually grow businesses.
At the end of the day, we need to be smarter than the platforms we use. Automation is here to stay, but it doesn’t replace good marketing. Focus on what really matters: educating your clients, measuring profitability, and driving real growth.
If you take nothing else from this post, remember this: teach before you disrupt, track actual business health, and never stop thinking like a marketer. That’s how you stay relevant in a world where AI is trying to commoditize everything.
