Learn MoreWhy Performance Max is so hard to control
Performance Max campaigns are designed for broad reach and automated optimization, which can sometimes feel like a black box. Understanding its inner workings is the first step to effective management.
The black box problem: what PMax hides from you
PMax operates with a high degree of automation, meaning Google's AI makes many decisions regarding targeting, bidding, and ad serving. This "black box" nature can make it difficult to pinpoint exactly why certain ads are showing or why budget is being allocated in unexpected ways. Without transparency, advertisers often feel a loss of control.
How broad match and PMax interact
PMax heavily relies on broad match keywords and audience signals to find converting customers. While this can uncover new opportunities, it also means your ads can appear for a very wide range of search queries, many of which might be irrelevant to your business. This interaction is a primary driver of uncontrolled ad spend.
Where budget actually goes inside a PMax campaign
Without granular controls, it's easy for your budget to be funneled into placements or search queries that yield low ROI. Understanding the potential drain points is crucial for optimizing your overall ad spend. This is where strategic use of negatives and exclusions becomes paramount.
Negative keywords in Performance Max: the 2026 update
Google has significantly evolved its approach to negative keywords within Performance Max, offering more control than ever before.
The history: from 100 to 10,000 keywords (January–March 2026)
Initially, PMax offered very limited options for negative keywords. However, recent updates have expanded this capability dramatically. As of early 2026, advertisers can now add up to 10,000 campaign-level negative keywords, providing a powerful tool to refine targeting. This is a significant leap from earlier limitations.
How to add campaign-level negatives in the new interface
Adding campaign-level negatives is now more straightforward. Navigate to your PMax campaign, then go to "Settings." You'll find a dedicated section for "Negative keywords." Here, you can either add individual keywords or upload a list. It’s essential to leverage shared negative keyword lists for efficiency.
[!TIP] Use shared negative keyword lists to apply the same set of negatives across multiple PMax campaigns, saving significant time and ensuring consistency.
What negative keywords do (and don't) block in PMax
Campaign-level negative keywords primarily impact the Search network within PMax. They prevent your ads from appearing for specific search queries on Google Search. However, they typically do not block your ads from showing on other networks like YouTube or Display, where placement exclusions are the more effective tool. Understanding this distinction is key to a comprehensive strategy. Mastering the negative keyword fundamentals is crucial for any Google Ads professional.

The Search Terms report is invaluable for understanding what users are actually searching for when your PMax ads appear.
How to access it (Insights & Reports tab)
To access the PMax Search Terms report, navigate to your PMax campaign. Click on the "Insights & Reports" tab in the left-hand menu, then select "Search terms." This section provides a detailed look at the queries that triggered your ads.
What data you can and cannot see
While the Search Terms report is powerful, it's not fully transparent. You can see the search queries, the associated campaign, ad group (if applicable), and performance metrics like clicks, impressions, and conversions. However, PMax's automation means you won't see specific targeting signals or the exact channel (e.g., Search, YouTube) where the impression occurred for every query.
How to use it to find new negatives weekly
Regularly reviewing this report is vital. Look for irrelevant or low-performing search terms. These are prime candidates for adding to your negative keyword list. Performing a weekly search terms audit can help you quickly identify and mitigate wasted ad spend.
| Report Data Point | Visibility in PMax |
|---|---|
| Search Query | Yes |
| Clicks | Yes |
| Impressions | Yes |
| Conversions | Yes |
| Network Type | Limited |
| Targeting Signal | No |
Placement exclusions in Performance Max
Beyond search queries, controlling where your ads appear on Google's network is crucial, especially for Display and YouTube.
Why Display placements drain budget silently
Display and YouTube placements can be significant budget drains if not managed carefully. Irrelevant websites, apps, or videos can lead to impressions and clicks that have zero conversion potential, silently eroding your ad spend without contributing to your goals.
How to identify toxic placements
Within the "Insights & Reports" tab of your PMax campaign, look for the "Placements" report. This section lists the websites, apps, and YouTube channels where your ads have appeared. Analyze these for low performance, high spend with no conversions, or simply irrelevant content.
Step-by-step: excluding placements in PMax
- Navigate to your PMax campaign.
- Go to "Settings."
- Find the "Placements" section.
- Click "Add placement exclusions."
- You can exclude specific URLs, domains, or mobile apps.
- Add the identified toxic placements to the exclusion list.
[!IMPORTANT] Placement exclusions in PMax are applied at the account level for Display and YouTube, but not for Search.
Brand exclusions vs negative keywords
Google offers specific brand exclusions within PMax, which function differently from standard negative keywords.
What brand exclusions cover that negatives don't
Brand exclusions allow you to prevent your PMax campaigns from appearing on searches for specific brands (including your own). This is particularly useful if you want to maintain brand purity or avoid competing with your own branded search campaigns running elsewhere. Negative keywords block specific search terms, while brand exclusions block brand searches.
How to set up brand exclusions correctly
Brand exclusions are found within the PMax campaign settings. You'll see an option to exclude specific brands. Enter the brand names you wish to exclude. This is a powerful way to refine your PMax targeting and ensure it doesn't cannibalize other, more specific campaigns.
PMax negative keyword strategy for agencies
Agencies managing multiple PMax accounts need robust strategies for efficiency and scalability.
Shared lists: what works and what doesn't
Shared negative keyword lists are a lifesaver for agencies. Creating master lists of commonly irrelevant terms (e.g., "jobs," "free," competitor names if not desired) and applying them across all PMax campaigns is highly effective. What doesn't work is relying solely on campaign-specific lists, which leads to duplication of effort and inconsistencies. This is a core part of managing PMax across accounts.
Building a scalable review workflow
A scalable workflow involves regular audits of the Search Terms report and placement data across all managed accounts. Implementing a structured process for identifying new negatives, updating shared lists, and applying exclusions ensures that auditing PMax at scale is efficient. Leveraging AI tools can significantly enhance this process, allowing for faster identification of trends and anomalies. The 3 types of AI automation in Google Ads can be instrumental here.
