Google started auto-migrating Broad Match to AI Max

Google began automatically migrating Search campaigns using Campaign-level Broad Match and Automatically Created Assets to AI Max on September 1, with Dynamic Search Ads following in February 2027. Existing brand inclusions and exclusions carry over during migration, but teams with heavily customized legacy setups should review their accounts before the process completes. Given how broadly this affects standard Search campaign structures, it's worth flagging even to teams who haven't actively opted into AI Max features.
