Summary
We will no longer offer the autobidding type "Enhanced CPC." We've been expanding and improving autobidding types. As a result, the autobidding types "Maximize conversions" and "Maximize conversion value" are more likely to perform as well as or better than "Enhanced CPC" in their ad performance. Given this situation, we have decided to end the enhanced CPC.
We will implement the discontinuation in stages. Refer to the details of each stage as follows.
End of enhanced CPC setup
Date
June 18, 2025
Summary
We have ended the enhanced CPC setup.
When creating or modifying campaigns, you can't set up enhanced CPC.
For existing campaigns with enhanced CPC, we recommend changing to a different autobidding type according to your goals. Learn more about Bid strategy setting in campaigns.
If you leave it to enhanced CPC, the system will change it to manual bidding "Individual CPC." Refer to the next section, "Migration of bid strategies by system," for more information.
Migration of bid strategies by system
Date
June 18, 2025 to June 30, 2025
Summary
We have started the migration to system-driven bid strategies.
The system will change campaigns set with Enhanced CPC to manual bidding "Individual CPC" by June 30, 2025.
*The migration will run gradually on an account-by-account basis. We can't specify when it will apply to your account.
Even after migrating to system-driven bid strategies, you can still change to other autobidding types. When deciding which bid strategy to select, use the A/B test. Learn more.
End of enhanced CPC
Schedule
June 30, 2025
*This date is subject to change.
Summary
We will end the offering of enhanced CPC.
Along with the system migration, the enhanced CPC items will be removed from the report creation view and existing templates. After the items are removed, even if you create reports for the duration before the migration using existing templates, you won't be able to confirm the enhanced CPC settings.
We will also remove the following items that have already been discontinued:
- Target Position in search results
- Enhanced CPC (previously "Maximize conversions")
If you create a performance report after these items are removed, they will appear as "Other." We recommend creating reports before the discontinuation to check performance that includes these items.
