Are Your PMax Ads Showing Up in the Wrong Places?

Performance Max (PMax) is billed as an automated, low-maintenance Google Ads solution. But it comes with challenges. One key issue: Pmax may place ads on sites that have nothing to do with your content. Without careful Google Ads monitoring, your ads will be racking up impressions on kids' lullaby channels, puzzle apps or sleep meditation videos that play in the background while someone’s phone is idle. People on these sites aren’t actively shopping, researching, or paying much attention. You will see impressions pile up, or clicks that never convert. Over time, those placements can drain budget without adding value. Here’s how to take back control.

Where Do PMax Ads Appear?

Most advertisers assume their ads are appearing alongside relevant content, such as industry blogs, news sites, or YouTube videos tied to their audience. However, with Pmax, ads appear across all of Google's advertising channels from a single campaign, including YouTube, Display Network, Search, Discover, Gmail, and Maps. Designed to drive conversions, they use AI to place ads on websites, mobile apps, and video content. Google bills it as a solution that allows you to find more converting customers, across Google's channels.

But unlike traditional campaigns where you pick your targeting, PMax decides autonomously where to serve your ads based on signals and conversion goals. While this can maximize scale, it also means your e-commerce campaign could be reaching users who are actively trying to fall asleep.

Takeaway 

Low-intent placements can inflate your impression and click counts while delivering little to no conversion value. 

Examples of Low Quality Placements

Here are some examples of placements that tend to drain the budget without delivering results: 

Placement Type	What It Looks Like	Why It’s a Problem
Sudoku & Puzzle Sites	Brain games, word searches, casual puzzles	Low intent, frequent accidental clicks
Kids & Lullaby Content	Nursery rhymes, cartoons, children’s YouTube channels	Irrelevant audience, poor conversion rates
Sleep & Meditation Videos	Ambient sounds, white noise, sleep playlists	Passive listening, little to no engagement
Mobile Gaming Apps	Free-to-play games, in-app ads	High volume, low-quality traffic
Clickbait Content Farms	“You won’t believe…” articles, viral-style sites	Low trust, poor user intent

How to See Where Your Ads Are Running?

One place to start is the “Where ads showed” report inside Google Ads. You can find it under Insights and Reports, and it gives you a view into websites, apps, and YouTube placements tied to your campaigns.

Another option is the Report Editor, which allows you to build a simple table with placements and impressions that you sort and scan quickly. Once you export it, you will start to see patterns, especially when you’re looking at a 30- or 90-day window.

How to Exclude Placements?

To exclude a placement, navigate to Campaign Settings, then Brand Safety and Placement Exclusions, or manage them at the account level by going to Tools, Shared Library, and Placement Exclusion Lists.

Pro Tip

Build a shared placement exclusion list at the account level so exclusions apply automatically to all current and future PMax campaigns.

Excluding Mobile Apps

Another proactive option is to exclude mobile apps altogether. Rather than excluding mobile apps one placement at a time, you can exclude mobile apps across your entire account. To do this, go to Campaigns > Content > scroll to Exclusions > Edit exclusions. Here you can choose Account, Campaign or Ad group. We recommend "Account" > Browse > App categories and opt out of at the very least gaming apps.

How Often Should You Check Placement Reports?

Placement data accumulates over time, and new inventory is constantly being added by Google. This means that you need a regular review schedule to spot and address problem placements. 

A monthly review is recommended for most accounts, to allow you to exclude problem placements before then consume your budget. For higher-spending accounts of $5,000 or more per month, a biweekly or weekly review could be appropriate. 

Add placement review to your standard account maintenance checklist alongside search term reviews and asset performance checks, and spend 15-20 minutes on the review. 

The Bottom Line

Performance Max and its automated features are powerful, but require careful monitoring. Regularly auditing your placements and building out exclusion lists is a simple, high-leverage optimization. A quick, regular check of placements can uncover wasted spend, improve traffic quality, and give the algorithm better signals over time.
