Top 9 Ideas for Optimizing Performance Max Campaigns

We often discuss specific aspects of optimizing ad campaigns and improving their results. In this article, we have compiled the maximum number of methods we use in different situations, focusing on the specifics of Performance Max campaigns in Google Ads, as these are the ones we use most for e-commerce advertising.

We have grouped possible issues and solutions in the context of these campaigns.

1. Declining Ad Performance (Low CTR, Few Conversions)

Solutions:

  • Negative Keyword Exclusions: While Performance Max doesn’t support traditional negative keywords at the campaign level, you can request Google support to add account-level negative keywords. This helps avoid irrelevant search queries.
  • Editing Asset Group Texts: Since Performance Max automatically creates ad variations based on your assets, it’s essential to update ad texts regularly.
  • Replacing Overlay Images: High-quality visuals are critical in Performance Max. Replace underperforming images or videos with new ones that better capture user attention.

2. Decrease in Sales or Leads

Solutions:

  • Adding New Audiences: Since Performance Max uses automated audience selection, adding audience signals (such as customer lists and remarketing lists) helps the system target high-potential conversion audiences better.
  • Location Adjustments: Performance Max targets audiences across multiple regions, but you can exclude irrelevant geographic locations in campaign settings.
  • Changing Bidding Strategies: If a campaign is underperforming, try switching to a more aggressive bidding strategy (e.g., Maximize Conversions or Target ROAS) to increase leads or sales.
  • Adding New Conversion Actions: Set up additional conversion tracking actions, especially for multi-channel strategies where a significant portion of orders comes via phone calls or website inquiries.

3. High Cost per Conversion (CPA)

Solutions:

  • Bid Adjustments: Performance Max supports automated bid strategies like Maximize Conversions or Target ROAS. If your CPA is too high, adjust your strategy or lower your target CPA.
  • Disabling Underperforming Products: If certain products consume budget without results, exclude them or entire product categories from the campaign.

4. Low Traffic Quality (Low Conversion Rate or CTR)

Solutions:

  • Excluding Underperforming Placements: Remove ineffective sites or mobile apps by adding account-level exclusions.
  • Location Adjustments: If the campaign generates irrelevant traffic in specific regions, exclude or limit those locations.
  • Optimizing Asset Groups: Updating creatives (visuals, ad texts) can help attract more relevant users.
  • Adding New Audiences: Use CRM data and remarketing lists to improve targeting and expand reach.
  • Creating New Remarketing Lists: Build remarketing lists based on previous site visitors and use them for more effective Performance Max retargeting.
  • Updating Audience Signals: Refreshing audience signals allows the system to optimize targeting towards more relevant user segments.

5. Disapproved or Blocked Products in Merchant Center

Solutions:

  • Resolving Product Disapprovals: If products are disapproved, identify the issue and submit them for review in Google Merchant Center.
  • Uploading New Feeds or Configuring Feed Rules: Update feed data and fix technical errors to restore product activity in Performance Max.
  • Adding Additional Feeds: Expand campaign capabilities by uploading supplementary feeds to increase product relevance in ads.

6. Inefficient Budget Usage

Solutions:

  • Excluding Ineffective Placements: Remove sites or apps that don’t generate conversions via account-level exclusions.
  • Budget Adjustments: Reduce budget for underperforming campaigns and reallocate funds to more successful segments.
  • Redistributing Budget: Assign separate product categories to different campaigns for more efficient budget usage. This is useful for products with many clicks but few conversions or those receiving no traffic, giving them a chance to appear in ads.

7. Incorrect Conversion Tracking in Ad Campaigns

Solutions:

  • Adding New Conversions: Setting up additional conversion tracking points in Google Ads enables more precise result measurement.
  • Excluding Irrelevant Conversions: Remove conversions that don’t align with business goals to get more accurate data.
  • Changing Attribution Models: Switching to attribution models that better reflect the multi-channel customer journey helps measure Performance Max effectiveness more accurately.
  • Analyzing Campaign Metrics: Regularly review key metrics to understand how tracking adjustments impact results.
  • Proper Conversion Value Setup: Ensure conversion values match actual purchases. Assigning a nominal value (e.g., $1) to other conversions helps track them without distorting ad performance analysis.

8. Technical or Payment Process Issues

Technical or payment profile problems can disrupt ad campaign continuity.

Solutions:

  • Contacting Support for Payment Profile Changes: If issues arise with your payment profile, reach out to Google support for a quick resolution.
  • Seeking Support for Other Issues: Don’t hesitate to contact Google support for technical or operational inquiries to prevent campaign downtime.
  • Communicating with Third-Party Service Providers: If using external services for call tracking or CRM integrations, maintain regular communication with their support teams to resolve integration issues.

9. Additional Optimization Ideas

Performance Max campaigns require continuous testing and new approaches to maximize results.

Solutions:

  • Campaign Metrics Analysis: Regularly review key performance indicators (conversion value, CPA, ROAS) to identify areas for improvement.
  • Developing Hypotheses and Testing: Create new hypotheses and experiment with different strategies to boost campaign effectiveness.
  • Analyzing Ad Profitability at the Product Level (Including Cross-Sales): Use analytical reports to track which products contribute to cross-sales and optimize product campaigns accordingly.
  • Using Scripts: Automation scripts help monitor ad performance, provide insights into placements and search queries, and assist in budget control within your ad account.

Conclusion

By implementing these optimization techniques, you can significantly enhance the efficiency of your Performance Max campaigns. Continuously analyze data, refine strategies, and leverage Google’s automation tools to achieve sustainable business growth.
