What You Need to Know
Starting November 17, 2025, Google Ads is changing how automatically created conversion goals are handled at the account level. This update fundamentally shifts the default behavior for customer conversion goals, with significant implications for campaign optimization and bidding strategies.
For data-driven paid advertising campaigns, this change represents an opportunity to exercise more precise control over which conversion signals influence automated bidding systems. Rather than having every new conversion action automatically become eligible for optimization across all campaigns, advertisers will now need to intentionally designate which goals should function as account defaults. This shift aligns with Google's broader commitment to helping advertisers eliminate wasted spend and ensure that machine learning algorithms focus on the metrics that truly matter to business outcomes.
Our AI automation services can help you optimize these automated bidding systems effectively while maintaining clear control over your conversion tracking configuration.
Current Behavior: How Conversion Goals Have Worked
Until this change takes effect, Google Ads has operated under a straightforward automatic process. When advertisers create new conversion actions through the Google Ads API, the platform automatically generates corresponding customer conversion goals and sets them as account defaults by default. This behavior extends to conversion actions created through other methods as well, making it simple for advertisers to get started with conversion tracking without additional configuration steps.
Under the current system, newly created conversion goals become biddable across all campaigns that are configured to optimize toward account-default goals. This means that every campaign using Maximize Conversions, Maximize Conversion Value, or Target CPA bidding strategies will consider these newly created goals alongside existing account defaults when determining how to allocate budget and set bids. While this approach ensures comprehensive tracking coverage, it can also introduce complications for advertisers who maintain sophisticated conversion funnels with both high-priority and lower-priority conversion actions.
Implications of Automatic Default Assignment
The automatic assignment of account-default status has created practical challenges for many advertisers. Consider an e-commerce business that tracks multiple conversion actions: a primary purchase conversion, a secondary add-to-cart action, a newsletter signup, and a page view conversion. Under the current behavior, each new conversion action automatically becomes eligible for bidding optimization, potentially causing campaigns to optimize toward easier-to-achieve secondary conversions at the expense of the primary purchase goal. This scenario is particularly problematic for advertisers running Performance Max campaigns, where the automated systems may not have sufficient guidance to prioritize the most valuable conversion actions.
Additionally, advertisers who frequently create test conversion actions or set up tracking for specific campaigns have found that their optimization algorithms behave unpredictably as new goals are added. The lack of explicit control meant that accidental or test conversion actions could inadvertently influence bidding behavior across the entire account.
What's Changing: The New Default Behavior
Beginning November 17, 2025, Google Ads will implement a conditional approach to account-default assignment for automatically created customer conversion goals. Under the new behavior, a newly created conversion goal will only receive account-default status if all existing goals within the same category are already designated as account defaults. If any goal within that category has been manually set to non-default status, new goals in that category will also be created as non-default by default.
This category-based logic introduces a new level of precision for advertisers managing diverse conversion portfolios. The system evaluates goals based on both their conversion action category (such as PURCHASE, SIGNUP, or LEAD) and their conversion origin (such as WEBSITE, APP, or STORE). When a new conversion action is created, Google Ads checks for existing goals with matching category and origin combinations. The default status of the new goal depends entirely on the default status of those existing goals.
Understanding Conversion Categories and Origins
Conversion categories in Google Ads organize conversion actions by their position in the customer journey. The primary categories include PURCHASE for transactional conversions, SIGNUP for account creation and registration actions, LEAD for form submissions and contact requests, PAGEVIEW for significant page visits, and APP_INSTALL for application downloads. Each category represents a different type of valuable customer action that advertisers may want to track and optimize toward.
Conversion origins indicate where the conversion event occurs. The WEBSITE origin covers conversions happening on web properties, APP covers mobile and tablet application events, STORE covers in-person transactions, and PHONE covers call-based conversions. By considering both category and origin together, Google Ads enables advertisers to maintain separate tracking and optimization configurations for different conversion types across different platforms.
Practical Example of the New Logic
Consider an advertiser who has two existing conversion goals in their account. The first is a purchase conversion from their website, which they have intentionally kept as a non-default goal because they want to manage it separately in specific campaigns. The second is a newsletter signup conversion, also from their website, which they have set as an account default.
When this advertiser creates a new purchase conversion action for tracking a different product category, the new goal will be created as non-default because an existing purchase goal is already non-default. However, if they create a new signup conversion action, that goal will be created as account default because the existing signup goal is default. This behavior ensures consistency within each conversion category while giving advertisers granular control over the entire portfolio.
This example illustrates how the new approach provides category-based consistency, preventing mixed signals within related conversion actions while still allowing advertisers to maintain precise control over their optimization configuration.
Why Google Is Making This Change
Google's decision to modify default conversion goal behavior stems from extensive analysis of advertiser outcomes and campaign performance patterns. The company identified that automatic account-default assignment often led to suboptimal bidding behavior, particularly for advertisers who maintain comprehensive conversion tracking with both primary and secondary goals. By introducing conditional default assignment, Google aims to help advertisers achieve better performance through more intentional goal management.
The Performance Impact of Mixed Signals
Automated bidding systems in Google Ads rely on conversion data to learn and optimize. When campaigns receive conversion signals from multiple goals with different levels of business importance, the algorithms must balance competing objectives. For advertisers who primarily care about purchases but have account-default status applied to lower-funnel actions like page views or add-to-cart events, bidding systems may optimize toward these easier-to-achieve conversions, artificially inflating apparent performance while delivering fewer actual business outcomes. The new default behavior addresses this challenge by encouraging advertisers to be explicit about which goals should influence bidding.
Alignment with Data-Driven Advertising Principles
This change aligns with broader industry trends toward more intentional, data-driven approaches to paid advertising. As third-party cookies deprecate and privacy regulations expand, the quality and relevance of conversion data becomes increasingly important. By encouraging advertisers to consolidate their optimization signals around core business objectives, Google is helping ensure that its automated systems have the clearest possible picture of what success looks like for each advertiser.
Technical Implementation Details
For advertisers and developers working with the Google Ads API, this change introduces new considerations for conversion tracking implementation. Understanding the technical mechanics of customer conversion goals and their relationship to conversion actions is essential for maintaining effective tracking configurations after the November 2025 transition.

Customer Conversion Goals Explained
Customer conversion goals serve as the bridge between conversion actions and campaign optimization. A conversion action defines what is being measured (such as a purchase completion or form submission), while a customer conversion goal determines whether that conversion should be considered in automated bidding calculations. Goals with account-default status--indicated by the biddable field being set to true--participate in optimization for campaigns configured to target account-default goals.
The CustomerConversionGoal object in the Google Ads API includes the biddable field, which controls whether the goal influences bidding behavior. When biddable is true, the goal functions as an account default. When biddable is false, the goal is tracked for reporting purposes but does not affect automated bidding. Prior to the November 2025 change, this field was automatically set to true for newly created goals, but the new behavior changes this default assignment logic.
API Behavior After the Change
After November 17, 2025, newly created customer conversion goals will have their biddable field set to false by default, except in cases where all existing goals with matching category and origin combinations already have biddable set to true. Advertisers who want a new goal to function as an account default must explicitly set the biddable field to true when creating or updating the goal.
For advertisers using the Google Ads user interface, this change manifests as a new checkbox option when creating conversion actions. The interface will clearly indicate whether the new goal will be created as a default based on existing goals in the same category, and advertisers can override this default assignment as needed. For API users, the same logic applies through the CustomerConversionGoal.biddable field.
Integration with Existing Workflows
Advertisers who have built automated workflows around conversion tracking should review their processes to ensure compatibility with the new behavior. Scripts that create conversion actions, automated rules that manage goal configurations, and third-party tools that interact with the Google Ads API may need updates to explicitly set biddable status for goals that should function as account defaults.
This is particularly important for advertisers using performance marketing platforms, call tracking solutions, or CRM integrations that automatically create conversion actions in Google Ads. These integrations should be reviewed to confirm that they will properly handle the new default behavior, either by explicitly setting biddable status for desired goals or by implementing the category-checking logic to determine appropriate default assignment.
Key areas to review:
- Scripts that create conversion actions
- Automated rules managing goal configurations
- Third-party tools and platforms
- Performance marketing platform integrations
- Call tracking and CRM solutions
- E-commerce platform connections
Best Practices for Managing Conversion Goals
Adapting to the new default conversion goal behavior requires a strategic approach to conversion tracking architecture. Advertisers should take this opportunity to audit their existing conversion goals, establish clear naming conventions, and implement governance processes that ensure goals are configured appropriately for their intended purpose.
Conducting a Conversion Goal Audit
Before the November 2025 transition, advertisers should review all existing conversion actions and customer conversion goals in their accounts. For each goal, determine whether it should function as an account default or serve purely as a measurement tool. Goals that directly contribute to business outcomes and should influence bidding should be designated as defaults, while secondary conversion actions used primarily for analytics can remain as non-default goals.
This audit process also provides an opportunity to consolidate redundant conversion actions and remove outdated tracking implementations. Many advertisers have accumulated multiple similar conversion actions over time, particularly when testing different attribution models or tracking implementations. Streamlining the conversion portfolio before the transition will simplify ongoing management and reduce complexity in goal configuration.
Establishing Category-Based Configuration Standards
Given the category-based logic of the new default behavior, advertisers should establish clear standards for how different conversion types should be configured. For most businesses, primary conversion categories like PURCHASE should have account-default status applied to the most important goal in that category, with additional goals in the same category configured as non-default to prevent mixed optimization signals.
Document these standards and share them with any team members or agency partners who manage the Google Ads account. Consistent configuration across the account ensures predictable behavior when new conversion actions are created and reduces the likelihood of accidental misconfiguration.

Implementing Governance Processes
For accounts with multiple users or frequent conversion tracking changes, implement governance processes that ensure appropriate goal configuration. This might include requiring review and approval before creating new conversion actions, establishing naming conventions that indicate intended default status, or implementing automated checks that flag unusual configuration patterns.
The new default behavior reduces the risk of accidental misconfiguration because new goals will not automatically affect bidding, but advertisers should still maintain awareness of how their conversion tracking changes might impact campaign performance. Regular reviews of goal configuration, particularly after creating new conversion actions, help ensure that the account continues to operate according to intended specifications.
Impact on Different Campaign Types
The change to default conversion goal behavior affects all campaign types that use automated bidding strategies, but the practical impact varies depending on how campaigns are configured and what conversion actions they are optimized toward.
Performance Max Campaigns
Performance Max campaigns present unique considerations because they automatically optimize toward account-default conversion goals across all inventory types. Advertisers running Performance Max should pay particular attention to their default goal configuration, ensuring that only the most valuable conversion actions receive account-default status. The new default behavior helps prevent Performance Max campaigns from optimizing toward secondary conversions, but advertisers must still be intentional about which goals they designate as defaults.
If a Performance Max campaign is underperforming or showing signs of optimizing toward the wrong outcomes, review the account-default goals and adjust as needed. Consider creating separate conversion goals specifically for Performance Max campaigns if different optimization signals are required compared to other campaign types.
Search and Shopping Campaigns
Search and Shopping campaigns often have more specific conversion goals compared to Performance Max, but they can still be affected by default goal configuration. Advertisers using Target CPA or Maximize Conversion Value bidding for these campaigns should ensure that their account-default goals align with the specific outcomes these campaigns should drive.
For Shopping campaigns focused on purchase transactions, ensure that purchase conversion goals have default status while excluding lower-funnel actions like add-to-cart from default configuration. This focus helps Shopping campaigns optimize toward actual sales rather than browsing behavior.
Search Campaigns Targeting Leads
For Search campaigns focused on lead generation, the considerations are similar but the relevant conversion categories differ. Ensure that primary lead form submissions have default status while any secondary actions like page views or clicks on contact pages remain as non-default goals. Clear separation between primary and secondary conversion actions helps Search campaigns learn effectively and allocate budget toward the most valuable outcomes.
Preparing for the Transition
Google has scheduled this change for November 17, 2025, providing advertisers with time to review their configurations and make necessary adjustments. Proactive preparation ensures a smooth transition and helps advertisers take full advantage of the new default behavior from day one.
Timeline for Action
Advertisers should begin reviewing their conversion goal configurations as soon as possible, with changes implemented before the November transition date. The review process typically requires coordination between marketing teams, analytics teams, and any external partners who manage conversion tracking implementation.
After the transition, monitor campaign performance closely to identify any unexpected changes in conversion volume or cost metrics. While the new default behavior should improve performance for most advertisers by reducing mixed optimization signals, individual account experiences may vary depending on current goal configurations and bidding strategy setups.
Testing and Validation
Before the transition, consider creating test conversion actions to observe the new default behavior in action. Create goals in categories where existing goals are configured as defaults and in categories where existing goals are non-default. Verify that the new behavior matches expectations based on the category-checking logic described above.
This testing provides confidence in the new behavior and helps identify any issues with API integrations, automated scripts, or third-party tools that may need updates to accommodate the change.
Recommended testing approach:
- Create goals in categories with existing default goals
- Create goals in categories with existing non-default goals
- Verify default assignment logic works as expected
- Test API integrations and automated workflows
