With the rollout of AI Max, advertisers will notice changes in their Search campaigns in Microsoft Advertising.

Also, AI Max settings can now be imported from Google Ads, allowing campaigns using scheduled imports to maintain their settings for future syncs.
Additionally, new Search campaigns created in Microsoft Advertising will have AI Max enabled by default but can be turned off at any point.
While Google has begun phasing out Dynamic Search Ads (DSA), Microsoft Advertising continues to support DSA campaigns for now. Any upgraded DSA campaigns imported from Google Ads will be reverted to standard DSA campaigns in Microsoft Advertising.
This article shares more details about the recent announcement that AI Max is now available globally.
