Google PMax Assets Specifications: Why Missing Data Hurts Campaigns (& How AI Fixes It)

Google PMax Assets Specifications: Why Missing Data Hurts Campaigns (& How AI Fixes It)

Google Performance Max (PMax)

Google Performance Max (PMax) campaigns promise a streamlined approach to digital advertising. They use automation to deliver ads across multiple Google channels, including Search, Display, YouTube, and Gmail. Advertisers upload assets—such as headlines, descriptions, images, and videos—and Google’s machine learning combines them to create ads.

While this automation saves time, it also creates a problem. Google Ads does not provide detailed asset-level reporting. Advertisers see performance data at the campaign level, but they cannot tell which individual images, headlines, or videos are driving results. Without this information, it is difficult to refine creative elements, allocate budgets effectively, or understand what works.

This lack of transparency is a concern, especially for Performance Max campaigns, where creative assets play a key role in success. Advertisers need to know which assets engage users and lead to conversions. Without asset-level insights, they are left guessing.

In this article, we will break down how Google PMax handles assets, why the lack of detailed data is a challenge, and how AI-powered creative analytics can solve this problem.

Understanding Google PMax Assets & Specifications

Google Performance Max (PMax) campaigns rely on a variety of creative assets to generate ads across multiple Google networks. Advertisers upload these assets, and Google’s machine learning system dynamically assembles them into ad variations based on user behavior and campaign goals.

Types of Assets in PMax Campaigns

PMax campaigns require multiple asset types:

• ‍Headlines – Up to 15 headlines, each with a 30-character limit. At least one should be 15 characters or fewer for better adaptability.‍
• Descriptions – Up to 5 descriptions, each with a 90-character limit. At least one should be under 60 characters.‍
• Images – Supports up to 20 images in different aspect ratios:‍
• Landscape (1.91:1) – Recommended size: 1200 x 628 px, minimum: 600 x 314 px.‍
• Square (1:1) – Recommended size: 1200 x 1200 px, minimum: 300 x 300 px.‍
• Portrait (4:5) – Recommended size: 960 x 1200 px, minimum: 480 x 600 px.‍
• Logos – Up to 5 logos in two formats:‍
• Square (1:1) – Recommended size: 1200 x 1200 px, minimum: 128 x 128 px.‍
• Landscape (4:1) – Recommended size: 1200 x 300 px, minimum: 512 x 128 px.‍
• Videos – At least one video is recommended, with a minimum length of 10 seconds. If no video is uploaded, Google may generate one automatically.‍
• Call-to-Action (CTA) – Can be selected from Google’s preset options or set to automated selection.

Google groups these assets into asset groups and rotates them to determine the most effective combinations. However, the reporting system does not provide detailed insights at the individual asset level.

How Google Reports PMax Asset Performance

Google Ads provides basic performance ratings for each asset rather than detailed metrics. Each asset receives one of four labels:

• ‍Best – Performs well compared to other assets in the same group.‍
• Good – Delivers solid performance but not the highest.‍
• Low – Performs worse than other assets.‍
• Learning – Still gathering data.

This reporting system has limitations:

• ‍No detailed metrics – Google does not provide individual asset-level data for click-through rate (CTR), conversions, impressions, or return on ad spend (ROAS).‍
• No context for underperformance – Assets labeled as “Low” may be removed from rotation, but advertisers do not receive an explanation.‍
• Limited optimization control – Without knowing why certain assets perform better, advertisers struggle to refine their creatives effectively.

Because Performance Max relies heavily on creative assets, this lack of asset-level reporting can prevent advertisers from making data-driven creative decisions. In the next section, we will explore why this is a major issue and how it affects ad performance.

The Problem: Why Limited Asset-Level Data in PMax is a Major Issue

Google Performance Max (PMax) campaigns rely on automation to optimize ad delivery. While this can improve efficiency, the lack of detailed asset-level reporting creates serious challenges for advertisers. Without clear data on how individual assets perform, advertisers struggle to make informed decisions.

Key Issues Caused by Limited Asset-Level Insights

• ‍No Visibility into High-Performing or Underperforming Assets‍
  • Google’s rating system (Best, Good, Low, Learning) does not provide actual performance metrics.
  • Advertisers cannot see click-through rate (CTR), conversion rate, or engagement levels for individual headlines, images, or videos.
  • Without precise data, it is difficult to know which assets drive results and which need improvement.

• ‍Reduced Creative Optimization‍
  • Advertisers cannot A/B test individual assets within PMax.
  • Poorly performing assets may be removed from rotation without explanation.
  • There is no way to adjust specific creatives based on performance trends.

• ‍Inefficient Budget Allocation‍
  • Without asset-level insights, advertisers cannot shift budgets toward the best-performing creatives.
  • Brands may waste ad spend on underperforming assets without realizing it.

• ‍Inability to Develop Data-Driven Creative Strategies‍
  • Creative elements like images, videos, and headlines influence conversions, but without detailed data, advertisers cannot identify patterns or trends.
  • Brands miss out on opportunities to repurpose effective creatives across other campaigns.

• ‍Limited Control Over Performance Max Optimization‍
  • PMax’s machine learning system decides which assets to use, but advertisers lack insight into how these decisions are made.
  • Without transparency, it is difficult to align creative strategy with business goals.

Google’s automated system does not replace strategic decision-making. Advertisers need clear asset-level data to refine their creatives and improve campaign performance. In the next section, we will explore why AI-powered creative analytics is essential for Performance Max advertisers.

The Need for Detailed Creative Analytics in Google Ads

Google Ads provides campaign-level insights, but Performance Max (PMax) campaigns rely on creative assets to engage audiences. Without detailed asset-level data, advertisers cannot make informed creative decisions. Creative analytics fills this gap by offering visibility into how individual assets perform, helping advertisers improve their campaigns.

Why Creative Analytics Matters for PMax Campaigns

• ‍Identifies High-Performing Assets‍
  • Creative analytics breaks down performance by asset, showing which headlines, images, and videos drive engagement.
  • Instead of relying on Google’s broad “Best” or “Low” labels, advertisers get precise data on click-through rates (CTR), conversions, and return on ad spend (ROAS) for each asset.

• ‍Enables Data-Driven Creative Decisions‍
  • Advertisers can A/B test different creative elements to refine messaging and visuals.
  • Instead of guessing which assets perform well, brands can adjust creatives based on actual data.

• ‍Improves Budget Allocation‍
  • With asset-level insights, advertisers can allocate more budget to high-performing creatives.
  • This prevents wasted spend on low-performing assets that Google’s automated system may still be using.

• ‍Enhances Creative Strategy Across Channels‍
  • By understanding what works in PMax, advertisers can apply the same insights to other platforms like social media and display ads.
  • High-performing headlines, images, and videos can be repurposed across multiple campaigns.

• ‍Gives Advertisers More Control Over PMax Performance‍
  • Google’s machine learning decides which assets to serve, but creative analytics provides the data needed to guide optimizations.
  • Instead of blindly trusting automation, advertisers can make informed changes that align with their marketing goals.
