Running PMax in 2025? Read THIS first!

Running PMax in 2025? Read THIS first!

Three years ago, Google launched Performance Max with promises of smarter automation and better results.

Instead, we got a half-baked campaign type—a black box filled with blind spots, brand cannibalization, and questionable decision-making.

Fast forward to 2025, and Google has finally started addressing some of PMax’s biggest issues. MORE reporting, BETTER controls, FEWER frustrating unknowns.

Sounds great? Well… kind of.


Google giveth, and Google taketh away.

The new “transparency” comes on Google’s terms. The AI still prioritizes what it wants, not what your business needs. You’re still locked into an opaque system, forced to make decisions with partial visibility at best.

So, what now?

You could trust the machine and let it steer your budget into the void. Or you could take control.

To help, we’ve pulled six of your most pressing PMax Q&As from Mike Ryan latest webinar 'PMax 2025: What's new for your ecommerce strategy'.

If you want to win in the age of AI-driven advertising, here’s what you need to know. ??



1?? Is it time to switch back to Standard Shopping from PMax?

?? PMax no longer automatically overrides Standard Shopping—so should you switch back?

This is not an either-or proposition, but w get why so many advertisers are throwing a ‘Hail Mary’ in light of Standard Shopping’s comeback.

Before October 2024, PMax would always take priority over Standard Shopping, effectively shutting it down in the same account.

Now, they compete based on ad rank, meaning Standard Shopping can serve alongside PMax—but that doesn’t mean it’s the better choice.

? Why we think PMax is still the better choice:

  • Expands beyond Standard Shopping’s Shopping-only placements to YouTube, Display, and Discover for broader reach.
  • Leverages audience signals to guide performance beyond just product feed data.
  • Provides incrementality testing options like geo-split tests and Search Term Insights to improve transparency.

?? But beware: Since PMax and Standard Shopping now compete on ad rank, running both without clear differentiation can cause budget inefficiencies and cannibalization.

While Performance Max might achieve a lower impression share than Standard Shopping, it makes up for it with broader reach across Google's entire ad offering.

2?? Should I still run Search campaigns alongside PMax?

?? Yes—because PMax and Search serve different roles.

Google now promotes PMax + Search as an "Ads Power Pairing," but here’s the catch: PMax doesn’t use keywords like traditional Search campaigns.

Instead, it behaves more like Dynamic Search Ads (DSAs), automatically matching queries to your ads.

This means that if you rely only on PMax, you lose control over search intent and risk higher CPCs on brand terms.

? Best practice:

  • Keep running Search campaigns for high-intent keywords and brand protection.
  • Use PMax to discover new traffic and expand reach.
  • Regularly check Search Term Insights to spot brand cannibalization.

?? Heads-up: If PMax is bidding on your brand terms, it may drive up costs unnecessarily. You can request brand exclusions via a Google rep—but they don’t apply to all placements.



3?? How should I structure PMax campaigns in 2025?

?? One massive PMax campaign = lost control.

Google’s AI prioritizes best-sellers and products with strong historical data, which means newer or strategically important items often get ignored. This is why dumping your entire catalog into a single PMax campaign is a bad idea.

Instead, proper segmentation is key to making sure your budget supports the right products.

? How to structure PMax effectively:

  • Segment campaigns by product type, seasonality, margins, AND performance
  • Use separate campaigns, not just asset groups—they don’t control budget allocation.
  • Feed PMax with audience signals to help guide targeting.

?? Reminder: Google’s automation favors products that already convert well. If you want to boost underperformers, structure your campaigns accordingly.


4?? How do I measure PMax’s true impact?

?? Google’s default reporting won’t tell you if PMax is actually bringing in new customers—or just recycling existing traffic.

One of the biggest frustrations with PMax is the lack of clear incrementality measurement. If you’re not careful, PMax might take credit for sales that would have happened anyway.

To avoid this, you need to run structured tests.

? How to measure true PMax impact:

  • Geo-split tests—run PMax in one region but pause it in another to compare results.
  • Use Google’s New Customer Acquisition (NCA) mode to track fresh conversions.
  • Monitor Marketing Efficiency Ratio (MER) to measure overall revenue lift.

?? Pro tip: Google’s New Customer Matching isn’t perfect. Always cross-check with your CRM data.


5?? Can I still run feed-only PMax campaigns?

?? Yes—but Google is making it harder.

Feed-only PMax campaigns limit PMax to Shopping inventory and avoid wasteful YouTube, Display, and Discovery placements.

Many advertisers prefer this approach to keep tighter control over budget allocation.

However, Google has made it more difficult to set up feed-only PMax. While it’s still possible, it requires workarounds.

? Why feed-only PMax still works:

  • Keeps budget focused on Shopping placements.
  • Prevents spending on low-quality display/video placements.
  • Pairs well with Demand Gen campaigns for better creative control.

?? Heads-up: Google may fully remove this option in the future, so keep an eye on updates.


6?? How can I use audience signals effectively in PMax?

?? Audience signals don’t limit reach, but they help guide Google’s AI.

Many advertisers assume that adding audience signals in PMax is like using strict audience targeting—but it’s not. Instead, Google uses signals as a learning tool, then expands beyond them.

? How to make audience signals work for you:

  • Upload first-party data (e.g., past customers, high-value shoppers).
  • Regularly update signals—Google’s AI can drift over time.
  • Test geo-splits to measure signal effectiveness.

?? Myth-buster: Adding audience signals does NOT restrict PMax targeting. Google will still go beyond your inputs to find additional audiences.


7?? What’s the best way to report on PMax performance?

?? Google has improved PMax reporting—but there are still gaps.

Advertisers now have access to:

  • Enhanced Search Term Insights (more transparency into queries).
  • Unofficial placement reports (using scripts to estimate YouTube & Display reach).
  • Auction Insights (for better Shopping & Search segmentation).

However, some key reporting issues remain:

?? What’s still missing?

  • No overall impression share for PMax—only available for Search & Shopping.
  • Limited brand protection controls—brand exclusions don’t apply everywhere.
  • Lack of clear cross-channel insights—PMax blends traffic sources together.


?? 2025 is PMax's biggest year yet—so make sure you're ahead of the curve!

Performance Max has come a long way, but it’s still not perfect. With big updates dropping fast, the question isn’t if you should adapt—but how.

Mike Ryan’s latest webinar breaks down what’s new, what’s better, and what might just be worse, saving you the headache of figuring it out alone.

?? Would you trust Google with your wallet?

No, seriously.

Because that’s exactly what happens when you advertise with an open budget. Google takes the reins, spends without asking permission, and decides where your money goes.

So, is it a marketing masterstroke or a fast track to losing control?

That’s the question we’re tackling in Episode 1 of ROASted—our brand-new video series where we take the biggest myths in PPC, throw them on the grill, and see if they hold up... or go up in flames.

?? In this episode, we break down:

  • How to stop Google from burning through your ad spend without a safety net.
