Understanding Performance Max Asset Groups
Performance max asset groups are the fundamental building blocks of your Performance Max campaigns. Each asset group contains a collection of text, image, video, and other creative assets that Google’s machine learning algorithms combine and test across all available Google channels including Search, Display, YouTube, Gmail, and Discover.
We build performance max asset groups to give Google’s automation the raw materials it needs to create relevant ad combinations for different placements and audiences. Rather than creating individual ads for each channel, you provide a library of assets that Google dynamically assembles based on where and to whom it serves the ad.
Each campaign can contain up to 100 asset groups, though most accounts perform better with fewer, more focused groups. The key is to organise your asset groups around distinct product categories, service lines, or audience segments rather than creating one massive group with unrelated assets.
Important: Asset groups are not the same as ad groups in traditional Search campaigns. They function more like self-contained mini-campaigns with their own creative library and audience targeting signals.
How to Structure Your Asset Groups for Maximum Performance
The way you structure performance max asset groups directly impacts campaign performance. Poor structure forces Google’s algorithms to show irrelevant combinations, wasting budget and reducing conversion rates.
We recommend organising asset groups by product category or service type. If you sell both shoes and handbags, create separate asset groups for each category. This ensures that headlines about running shoes never appear alongside images of handbags, maintaining message consistency across all placements.
Product-Based Structure
For e-commerce businesses, structure your asset groups around product categories that share similar characteristics and appeal to similar audiences. A clothing retailer might create separate groups for:
- Men’s formal wear
- Men’s casual wear
- Women’s formal wear
- Women’s casual wear
- Children’s clothing
- Accessories and footwear
Service-Based Structure
Service businesses should create asset groups for distinct service offerings. A digital marketing agency might separate:
- SEO services
- PPC management
- Social media marketing
- Content creation
- Web design and development
Audience-Based Structure
You can also structure asset groups around different customer segments when the same product appeals to different audiences with different messaging. A project management software company might create separate groups for:
- Small business owners
- Enterprise IT managers
- Marketing teams
- Construction companies
Pro Tip: Start with 3-5 asset groups per campaign. You can always add more once you identify which structures perform best for your business.
Asset Requirements and Specifications for Performance Max
Understanding google ads performance max assets requirements ensures you provide everything the system needs to create effective ad combinations. Missing asset types limits where your ads can appear and reduces overall campaign reach.
Required Assets
Every asset group must include these minimum requirements:
| Asset Type | Minimum Required | Maximum Allowed | Specifications |
|---|---|---|---|
| Headlines | 3 | 5 | 30 characters maximum |
| Long Headlines | 1 | 5 | 90 characters maximum |
| Descriptions | 2 | 4 | 60 or 90 characters |
| Images | 1 | 20 | Multiple aspect ratios |
| Logos | 1 | 5 | Square and landscape |
| Videos | 0 | 5 | YouTube hosted |
Image Requirements
Google requires images in multiple aspect ratios to accommodate different placements. We recommend uploading the maximum number of high-quality images in each ratio:
- Landscape (1.91:1): 1200 x 628 pixels minimum
- Square (1:1): 1200 x 1200 pixels minimum
- Portrait (4:5): 960 x 1200 pixels minimum
All images must be clear, properly lit, and free from excessive text overlay. Google’s automated systems may disapprove images with more than 20% text coverage.
Video Assets
While videos are optional, including them significantly expands your reach to YouTube placements. Videos must be hosted on YouTube and linked to your Google Ads account. We recommend creating videos in both horizontal (16:9) and vertical (9:16) formats.
Note: If you do not provide videos, Google will automatically generate simple video assets from your images and text. These auto-generated videos rarely perform as well as professionally created content.
Step-by-Step: Creating Your First Performance Max Asset Group
Follow this process to build your asset groups correctly from the start. Proper setup prevents performance issues and reduces the need for extensive revisions later.
Create or Select Your Campaign
Navigate to your Google Ads account and either create a new Performance Max campaign or select an existing one. If creating a new campaign, complete the initial setup including conversion goals, budget, and location targeting before building your asset groups.
Name Your Asset Group Strategically
Click the plus button to create a new asset group. Give it a descriptive name that clearly identifies the products or services it contains. Use naming conventions like “Product-Category-Audience” for consistency across multiple groups.
Add Your Product Feed
If you run an e-commerce business with a Merchant Center feed, link it to your asset group. You can select all products or use filters to show only specific categories. This automatically provides product images, prices, and availability information.
Upload Text Assets
Write and upload all required text assets. Create diverse headlines that highlight different benefits, features, and calls to action. Your descriptions should expand on the headlines and provide additional context about your offer.
Upload Images and Logos
Add high-quality images in all required aspect ratios. Upload your logo in both square and landscape versions. Ensure all images are relevant to the specific products or services in this asset group.
Add Video Assets
Link relevant YouTube videos if available. Select videos that demonstrate your products, explain your services, or showcase customer testimonials. Videos should match the theme and messaging of your other assets.
Set Final URLs
Enter the landing page URL where you want to send traffic from this asset group. For best results, the landing page should closely match the products or services featured in your assets.
Configure Audience Signals
Add audience signals to guide Google’s machine learning during the initial learning phase. We cover this in detail in the next section.
After completing these steps, review your asset group for completeness. Google displays an asset strength rating (Poor, Average, Good, Excellent) based on the quantity and quality of assets provided. We aim for “Excellent” ratings on all asset groups.
If you need help setting up your campaigns properly, our Google Ads management service includes complete Performance Max setup and optimisation.
Setting Up Audience Signals for Asset Groups
Audience signals are suggestions you provide to guide Google’s algorithms towards your most valuable customers. Unlike traditional targeting, these signals do not restrict who sees your ads, but they influence who sees them during the critical learning phase.
We include audience signals in our pmax asset group best practices because they significantly reduce the time needed for campaigns to reach optimal performance. Without signals, Google must experiment more broadly to identify converting audiences.
Types of Audience Signals
You can add several types of audience signals to each asset group:
- Custom segments based on keywords, URLs, and apps
- Your data segments including website visitors and customer lists
- Interest and demographic audiences
- Life event audiences
- In-market audiences
Best Practices for Audience Signals
Add 2-5 audience signals per asset group. Too many signals dilute the guidance you provide, while too few limit the algorithm’s understanding of your target market.
We prioritise your data segments first because they represent people who have already interacted with your business. Website visitors who viewed specific product categories make excellent signals for asset groups focused on those products.
Custom segments built around relevant keywords work well for asset groups targeting specific search intent. If your asset group promotes running shoes, create a custom segment with keywords like “running shoes”, “marathon training”, and “trail running”.
Pro Tip: Create tighter audience signals for higher-value asset groups and broader signals for top-of-funnel awareness groups. This balances efficient spending on qualified audiences with sufficient reach to find new customers.
How to Optimise Asset Groups After Launch
Learning how to optimize asset groups is essential for long-term campaign success. Initial setup is just the beginning. Regular optimisation based on performance data drives continuous improvement.
Asset Performance Review
Google provides performance ratings for each individual asset within your groups: Low, Good, or Best. Review these ratings weekly during the first month and monthly thereafter.
Replace “Low” performing assets with new variations that test different messaging, imagery, or calls to action. Keep “Best” performing assets unchanged unless performance declines over time.
We replace one or two underperforming assets at a time rather than making wholesale changes. This allows you to identify which specific changes improve results.
Testing New Asset Combinations
Add new assets to test different approaches:
- Benefit-focused headlines versus feature-focused headlines
- Product images versus lifestyle images
- Direct calls to action versus softer language
- Price-focused messaging versus quality-focused messaging
Allow at least two weeks of data collection before evaluating new assets. Google needs time to test new assets across different placements and audiences.
Audience Signal Refinement
After the initial learning phase, analyse which audience signals correlate with better performance. The audience insights report shows which signals generated the most conversions.
Remove audience signals that show poor conversion rates or high cost per conversion. Add new signals based on converting customer characteristics you identify in the data.
Budget Allocation Between Asset Groups
If you run multiple asset groups within one campaign, they share the same budget. Google automatically allocates more budget to better-performing groups, but you can influence this by pausing underperforming groups or splitting them into separate campaigns.
Note: Asset groups need at least 30-50 conversions before you can accurately assess their performance. Give new groups sufficient time and budget to exit the learning phase before making major changes.
Landing Page Alignment
We regularly review the relationship between asset messaging and landing page content. If your assets promise free shipping, your landing page must prominently display that offer. Misalignment between assets and landing pages increases bounce rates and reduces conversion rates.
Update your landing pages to match your best-performing asset messages, or update your assets to better match proven landing page elements. This alignment improves quality scores and conversion rates simultaneously.
Monitoring and Analysing Asset Group Performance
Regular performance monitoring helps you identify optimisation opportunities and address issues before they waste significant budget.
Key Metrics to Track
We monitor these metrics for each asset group:
| Metric | What It Tells You | Action Threshold |
|---|---|---|
| Conversion Rate | How well assets and landing pages convert traffic | Below account average |
| Cost Per Conversion | Efficiency of ad spend | Above target CPA |
| Impression Share | Potential reach being captured | Below 50% |
| Click-Through Rate | Asset relevance and appeal | Below 2% |
| Asset Strength | Completeness of asset library | Below “Good” |
Analysing Search Term Reports
Review the search terms report to understand what queries trigger your asset groups. This reveals whether Google correctly interprets your assets and audience signals.
Add irrelevant search terms as negative keywords at the campaign level. If you see consistent patterns of irrelevant terms, it may indicate that your assets or audience signals need refinement.
Placement Performance
Check which placements drive your conversions. Navigate to the placements report to see performance across Search, Display, YouTube, Discover, and Gmail.
If specific placements consistently underperform, you cannot exclude them in Performance Max, but you can adjust your assets to better suit high-performing placements. For example, if YouTube drives most conversions, invest more in video asset quality.
Time-Based Analysis
We analyse performance by day of week and hour of day to identify patterns. If certain days or times generate better results, you can adjust budgets accordingly or create ad scheduling rules at the campaign level.
Proper tracking setup is essential for accurate performance analysis. Our GTM setup service ensures your conversion tracking captures all relevant data for optimisation decisions.
Troubleshooting Common Asset Group Issues
Even well-structured campaigns encounter issues. We have documented the most common problems and their solutions based on managing hundreds of Performance Max campaigns.
When you identify an issue, first check the asset group settings and approval status. Many problems stem from disapproved assets or incomplete configuration. Review Google’s policy notifications carefully.
If your asset group shows low impression share, this typically indicates either budget constraints or low asset strength. Increase your daily budget or add more diverse assets to improve reach.
Asset groups with high impressions but low clicks suggest that your creative assets do not resonate with the audiences seeing them. Test new imagery and headlines with stronger calls to action.
When you see good click-through rates but poor conversion rates, the problem usually lies in landing page experience or audience relevance. Review your audience signals and ensure your landing page matches asset promises.
Important: If you make changes to address an issue, allow at least one week before evaluating results. Immediate changes can disrupt the learning process and make problems worse.
Building Effective Performance Max Asset Groups
Success with performance max asset groups requires careful planning, thorough execution, and ongoing optimisation. We structure asset groups around distinct product categories or audience segments, provide diverse high-quality assets in all required formats, and guide machine learning with relevant audience signals.
The most successful campaigns start with excellent asset quality. Invest time in creating compelling headlines, professional imagery, and engaging videos rather than rushing to launch with minimum requirements. Google’s algorithms can only work with the materials you provide.
Regular monitoring and testing drive continuous improvement. Replace underperforming assets, refine audience signals based on conversion data, and ensure landing pages align with your messaging. Performance Max rewards accounts that actively optimise rather than those that set and forget.

Frequently Asked Questions
How many asset groups should I create in one Performance Max campaign?
Start with 3-5 asset groups per campaign, each focused on a distinct product category or audience segment. You can add more groups once you understand which structures work best for your business. Creating too many groups initially spreads your budget too thin and extends the learning phase. Each group needs sufficient conversion volume to optimise effectively.
Can I use the same assets across multiple asset groups?
Yes, you can reuse assets across different groups, but we recommend against it for best results. Each asset group should contain assets specifically tailored to its products, services, or target audience. Unique assets for each group allow Google to create more relevant ad combinations and provide clearer performance insights about which messages resonate with which audiences.
How long does it take for a new asset group to complete the learning phase?
Asset groups typically need 2-4 weeks to complete the learning phase, depending on your conversion volume and budget. Google requires approximately 30-50 conversions to optimise effectively. Higher budgets and conversion rates speed up this process. Avoid making changes during the learning phase as this resets the algorithm’s progress.
What is the difference between asset groups and ad groups?
Asset groups in Performance Max contain collections of creative assets that Google combines dynamically across all channels. Traditional ad groups in Search campaigns contain specific ads with fixed text that appear only on Search results. Asset groups give Google more flexibility to create relevant combinations, while ad groups provide you with more control over exact messaging.
Should I add audience signals to every asset group?
Yes, we recommend adding 2-5 audience signals to every asset group. These signals guide Google’s machine learning during the initial learning phase towards audiences most likely to convert. Signals do not restrict who sees your ads but influence early delivery. Use your first-party data audiences, custom segments based on relevant keywords, and in-market audiences that match your products or services.
Why does my asset group have low impression share?
Low impression share usually indicates either insufficient budget or low asset strength. If your daily budget runs out early, increase it to capture more opportunities. If budget is not the issue, add more assets to improve your asset strength rating. Groups with “Excellent” asset strength receive priority in the auction. Also check that your bids are competitive for your target audience.
How do I know which assets are performing best in my asset group?
Navigate to the asset group view and click on “View asset details” to see performance ratings for each individual asset. Google rates assets as Low, Good, or Best based on their contribution to campaign performance. Focus your optimisation efforts on replacing Low-performing assets with new variations while keeping Best-performing assets unchanged. Review these ratings weekly initially, then monthly once campaigns stabilise.
