The paid media landscape saw significant shifts this week, moving beyond new tool announcements to focus on underlying changes in platform functionality and advertiser control. Key developments include Google's expansion of Performance Max, Microsoft's firm stance on brand safety with a Clarity mandate, and a viral debate questioning the efficacy of Google's "AI-powered" campaign model. These stories collectively highlight a recurring theme: advertising platforms are actively redefining what control and accountability mean for advertisers.

Performance Max Expands to Waze and Adds Channel Reporting

Google has confirmed two notable updates for Performance Max (PMax) campaigns.

Firstly, PMax campaigns utilizing "Store Visits" as a campaign goal can now display businesses on Waze ad inventory. Businesses will appear as "Promoted Places in Navigation" pins for users. This update is available to all advertisers in the United States and requires no additional setup.

Secondly, Google has rolled out Channel Reporting for all PMax campaigns. While this feature has been gradually implemented over several months, it is now universally accessible to all advertisers.

Why Advertisers Should Pay Attention

The expansion to Waze means local intent now encompasses the navigation moment. For brands reliant on foot traffic, appearing to users driving near a location offers a fresh, real-world touchpoint.

The channel reporting update is equally significant. It helps shift discussions around PMax from simply "trusting the system" to understanding "where the system actually worked." This represents progress in transparency and reach, although it also introduces new variables that advertisers may need to explain. The true benefit lies not just in "more placements," but in the ability to connect ad surfaces to tangible outcomes with greater confidence.

Microsoft Clarity Now Mandatory for Third-Party Publishers

Navah Hopkins, Microsoft Ads Liaison, shared an important announcement for all third-party (3P) publishers on Microsoft Ads.

Her post indicated that all pages receiving Microsoft Ads clicks must have Microsoft Clarity enabled. The announcement garnered significant attention within the PPC industry, with Hopkins clarifying in the comments that an official statement from Microsoft would follow shortly, and that all Microsoft Ads partners had already been notified via email.

The post also raised questions regarding billing, specifically from Andy Hawes, who asked:

Thanks for this Navah Hopkins, but when you say "Any Microsoft Advertising clicks that do not have Clarity will be filtered out and result in nonbillable impressions/clicks." Are you suggesting that if you don't run clarity then you're Microsoft Ads won't cost anything? I'm assuming that is not the case? So could you explain that part please?

Hopkins clarified during the exchange that Microsoft is linking billable media to a verifiable on-site experience.

Why Advertisers Should Pay Attention

Microsoft appears to be prioritizing quality rather than merely adding a tracking footnote. By tying billable media to verifiable on-site experience, the platform aims to reduce questionable placements and provide brands with greater assurance that their ads appear in environments meeting baseline standards. This move suggests Microsoft is trading raw reach for enhanced trust. Advertisers should anticipate fewer ambiguous placements and more robust conversations with brand-safety teams. It also pushes the market towards a new norm where "transparency" includes insight into on-site behavior, not just a placement report.

The Industry Reacts to AI Max Performance Data

AI Max was another prominent topic on LinkedIn this past week, sparking considerable debate.

Xavier Mantica shared four months of comparative results between AI Max and traditional match types. His data indicated AI Max conversions cost $100.37 each, significantly higher than the $43.97-$61.65 range for most non-AI setups, and even above the $97.67 for phrase close variants. Mantica's conclusion was that AI Max behaves similarly to broad match, extending beyond intended relevance and consequently increasing costs. The LinkedIn post garnered substantial engagement, with 991 reactions and over 170 comments from PPC professionals.

How Advertisers Are Reacting

Many PPC professionals commenting on the post seemed to agree that AI Max has not yet lived up to Google's initial hype. Collin Slatterly, Founder of Taikun, expressed "skeptical optimism," suggesting that AI Max might simply not be ready for its full potential:

Give it a year, and it'll probably be ready to deploy. Feels like PMax all over again.

Mike Ryan, another prominent voice, supported Mantica's findings after analyzing 250 of his own campaigns. However, not all reactions were negative. Denis Capko, for instance, replied in the comments with a differing view, indicating positive results with AI Max.

Why Advertisers Should Pay Attention

This ongoing debate transcends individual account performance; it reflects a broader tension between ad volume and control. The claim that "AI increases conversions" is only compelling if cost, relevance, and repeatability withstand scrutiny. While the comments leaned heavily negative towards AI Max, this situation might be better viewed as growing pains rather than outright failure.

Automation continues to evolve rapidly, often outpacing the frameworks used to evaluate it, and advertisers are still learning how to effectively guide these systems. When supported by strong data quality, accurate conversion tracking, and robust negative signals, AI Max can deliver significant scale. However, without clear visibility into how the system interprets intent, results can vary widely. Discussions like Mantica's highlight the critical need for transparency as much as performance. Google also stands to benefit from such openness, as it fosters trust, helps advertisers use automation more responsibly, and ultimately strengthens the technology for everyone.

Theme of the Week: Accountability

The updates and discussions from the past week underscore a unifying theme: accountability in digital advertising. Google is expanding the reach of automation, Microsoft is raising the bar for monetization standards, and advertisers are re-evaluating the trade-off between control and convenience. As platforms increasingly rely on automation, the true competitive advantage will not come from early adoption, but from a deep understanding of how these systems operate. The crucial question for advertisers remains: are you truly confident in what your automation is achieving, or merely comfortable letting it run?
