Key Points

• ● Google’s recent update to Performance Max (PMax) campaigns, showing search terms in Search Terms reports, is a significant change for advertisers, enhancing visibility and control.
• ● Research suggests this update, rolled out in early 2025, allows advertisers to see which search queries trigger ads, their conversion rates, and integrate negative keywords directly, addressing previous criticisms of PMax’s “black box” nature.
• ● The evidence leans toward this being a game-changer for optimizing ad spend, with strategies like auditing brand terms, cleaning irrelevant traffic, and reviewing competitor terms being key for advertisers across all industries.

Why This Update Matters

First spotted by Hana Kobzová in March 2025 and still rolling out as of April 2025, this update integrates search term data directly into the standard Search Terms report, bringing much-needed clarity to PMax campaigns.

Detailed Insights:

• ● Access key metrics like impressions, clicks, and conversion rates across Google’s ecosystem.

Enhanced Transparency:

● Moves beyond AI-driven guesswork by showing exactly which queries trigger your ads.

Greater Control:

● Incorporates negative keyword functionality, aligning PMax with traditional Search campaign controls.

This newfound clarity empowers advertisers to make smart, data-driven adjustments for better budget management and improved campaign performance.

Immediate Optimizations for PMax Campaigns

This update goes beyond visibility – it enables actionable refinements. Here are three ways to optimize your PMax campaigns immediately:

● High-Cost Term Audit: Review search terms driving significant spend, such as branded or generic queries, to determine their value. If they’re not delivering incremental results, exclude them as negative keywords to redirect budget toward higher-impact areas. A free script from smarter-ecommerce.com can assist by tracking impressions and conversions for key terms. 

● Irrelevant Traffic Cleanse: Identify search terms with high impressions or clicks but low or no conversions – think informational queries like “how-to guides” or “images of [product].” Adding these as negatives sharpens focus on intent-driven traffic, potentially cutting wasted spend. One case noted $600/month squandered on irrelevant terms before optimization.

● Competitor Query Review: PMax may automatically target competitor-related terms. Analyze their performance to decide if they’re worth pursuing for market share or should be excluded if they underperform, giving you strategic control over competitive positioning.

This update reflects Google’s push to blend automation with advertiser oversight, offering a timely chance to refine strategies and eliminate inefficient spending.

Survey Note: Detailed Analysis of Google’s PMax Update and Implications

• ● Precise Query Insights: Reveals exact search queries triggering ads.
• ● Efficient Keyword Management: Quickly identify high-performing and non-performing keywords.
• ● Real-Time Optimization: Enables immediate exclusion of irrelevant terms via negative keywords.
• ● Granular Campaign Control: Offers deep insights into campaign dynamics for smarter budget allocation.

This update empowers advertisers to fine-tune their strategies with unprecedented precision and control, ensuring every ad dollar is spent efficiently.

Background and Significance

PMax leverages AI to optimize ad placements across Google’s channels, aiming for maximum conversions. However, its lack of search term transparency has frustrated advertisers needing precise control over budget allocation. Now, with metrics like CVR%, impressions, and clicks available, users can pinpoint what’s working and what’s not. The ability to add negative keywords – expanded from a 100-term limit to 10,000 – further enhances flexibility, moving beyond the clunky process of submitting exclusion requests.

Why It Matters

This update transforms PMax from a leap-of-faith tool into one with actionable insights. Advertisers can now:

See the exact search terms triggering ads and their performance metrics.

Eliminate low-value or irrelevant queries, optimizing budget allocation. For example, one campaign wasted $600/month on terms like “[product] pictures” with no intent. 

Use data to inform broader strategies, aligning with Google’s trend toward transparency in AI-driven tools, as seen in tests like channel reporting. This balance of automation and control responds to user feedback, making PMax more adaptable across industries and goals.

Optimization Strategies

The update unlocks immediate optimization opportunities, backed by industry insights:

High-Cost Term Audit:

What: Assess terms eating up budget, such as branded or broad queries, to ensure they drive value.

How: Use the Search Terms report to pinpoint non-performing queries and add them as negative keywords. Additionally, consider tools like adding custom scripts to monitor key metrics – such as impressions, clicks, and conversions – to guide your optimization decisions. This approach helps ensure your campaigns are always running efficiently and focused on high-value search terms.

Why: Prevents overspending on traffic that doesn’t deliver incremental gains.

Irrelevant Traffic Cleanse:

What: Spot terms with high engagement but no results, like informational or off-target queries.

How: Add these as negatives directly in the report, refining focus on intent-driven searches.

Why: Cuts waste, redirecting budget to terms more likely to convert, as seen in cases saving hundreds monthly.

Competitor Query Review:

What: Evaluate competitor terms PMax may target automatically.

How: Analyze their conversion potential in the report, keeping winners and excluding losers.

Why: Balances opportunity (capturing rival traffic) with efficiency, leveraging tools like Adthena for deeper insights. 

Additional Considerations

Advertisers can enhance PMax further with segmentation strategies, such as using custom labels (e.g., campaign goals, seasonality) and dense data inputs to boost tROAS. Tools like Adthena also recover visibility into terms missing from Google’s report, adding depth to analysis. Meanwhile, 2025 enhancements – like high-value customer modes and improved exclusion controls – complement this update. Note that the rollout is gradual, so access may vary by account.
