Summary

At the end of June 2025, we will no longer offer the autobidding type "Enhanced CPC." In Search Ads, 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 plan to take the following actions for the end of enhanced CPC.

End of enhanced CPC setup: mid of June 2025
Migration of bid strategies by system: mid to end of June 2025
End of enhanced CPC: late June 2025

End of enhanced CPC setup

Schedule

Mid of June 2025
*Wait for further announcements with detailed schedules.

Summary

When creating new campaigns or modifying existing campaigns you will no longer be able to set up enhanced CPC. For existing campaigns with enhanced CPC, we recommend changing to a different autobidding type according to your goals. 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.
