Microsoft Advertising is Phasing Out Manual Bidding Strategies with Enhanced CPC by 30th April 2021

Starting in March 2021 and continuing through April 2021, all existing search, shopping, and Dynamic Search Ads campaigns without any automated bidding strategies in place will be automatically migrated to Enhanced CPC. All ad groups and keywords will also be set to inherit bidding from their parent campaign.

To make this migration seamless, starting on April 5, 2021, any new campaigns created will no longer have the option of Manual CPC.

By April 30, 2021 any campaigns not yet using eCPC will be automatically migrated.
