Google has begun automatically upgrading eligible Search campaigns to AI Max, its AI-driven search advertising format, marking one of the most consequential changes to Google Ads in 2026. Advertisers who have not migrated on their own are now seeing campaigns shifted over automatically, following a mandatory rollout timeline Google confirmed for Search campaigns this month.
According to reporting from Search Engine Land, Google has set a firm migration timeline compelling advertisers running standard Search campaigns to move to AI Max, its expanded AI-powered targeting and creative format that broadens keyword matching and automates elements of ad creation. Broad match Search campaigns faced an automatic upgrade to AI Max on September 1, 2026, according to trade publication ppc.land, meaning advertisers who took no action were migrated by default rather than being given an indefinite opt-out window.
Separately, Google confirmed on its own advertising blog that Dynamic Search Ads (DSA) — a format that automatically generates ads from a website's content — are also being upgraded to AI Max, though that migration deadline has been pushed back to February 2027 after Google previously delayed the DSA-specific timeline in response to advertiser feedback.
AI Max represents the latest step in Google's multi-year push to automate more of the search advertising workflow, following earlier shifts like Performance Max and broad-match-by-default recommendations. Google has increasingly moved advertisers toward AI-managed campaign formats that reduce manual keyword-level control in exchange for automated optimization across a wider set of search queries and ad variations. The DSA migration delay — Google's second publicly acknowledged postponement in this rollout — reflects pushback from agencies and advertisers who said they needed more time to adapt reporting, negative-keyword governance, and budget controls to the new format.
For the digital advertising industry, mandatory migrations of this scale affect how thousands of businesses manage search budgets, measure performance, and structure campaigns. Because AI Max broadens keyword matching automatically, agencies have flagged the need for updated negative-keyword strategies to prevent ad spend from being directed toward irrelevant search queries. The shift also continues a broader industry trend: advertisers are ceding more granular control to AI systems in exchange for automation, a trade-off that has generated ongoing debate in the performance-marketing community over transparency and control.
Advertisers still running unmigrated Dynamic Search Ads campaigns have until February 2027 to transition, giving agencies additional runway to adjust reporting dashboards and internal workflows. Marketing teams are expected to spend the coming months auditing auto-upgraded broad match campaigns for keyword drift and reworking negative-keyword lists to match AI Max's wider matching behavior. Further guidance and reporting-tool updates from Google are expected as the migration proceeds through the rest of 2026.
What is Google AI Max for Search?
It is an AI-driven format for Google Search campaigns that broadens keyword matching and automates parts of ad creative generation, replacing more manually controlled elements of traditional Search campaigns.
Do advertisers have to migrate, or is it optional?
For eligible broad match Search campaigns, migration became automatic starting September 1, 2026, rather than remaining fully optional. Dynamic Search Ads campaigns have a later, but still mandatory, deadline of February 2027.
Why did Google delay the Dynamic Search Ads migration?
Google extended the DSA migration timeline after advertiser and agency feedback indicated more time was needed to adapt campaign structures, reporting, and keyword governance to the new format.
How does this affect campaign reporting?
Marketing analytics providers have noted that AI Max migration changes how performance data is structured and reported, requiring advertisers to update dashboards and attribution tracking accordingly.
Google's move to make AI Max migration mandatory for Search campaigns marks a significant shift in how search advertising is managed, pushing more advertisers toward AI-automated targeting even as some, like Dynamic Search Ads users, get extra time to adjust. The rollout underscores an industry-wide trend of automation displacing manual campaign control, with digital marketing teams now racing to adapt reporting and keyword-governance practices to the new default.
