Google Automatically Converts Broad Search Campaigns to AI Max Before September 2026

Google has set September 1, 2026 as the deadline for automatically upgrading all Search campaigns using broad match or automatically created assets to the AI Max system, with text customization enabled by default without advertiser intervention.

The AI Max system grants Google's algorithms the authority to rephrase search ads and automatically adapt their text to match user queries, narrowing advertisers' margin of control over messaging reaching their audience and shifting editorial decisions from marketing teams to AI models.

This shift coincides with Google's acceleration in integrating artificial intelligence into its advertising products, even as advertisers express growing concern over losing control over their messaging and brand identity, especially since the upgrade will also affect DSA (Dynamic Search Ads) campaigns.

This announcement represents a fundamental shift in the balance of power between Google and advertisers; whereas advertisers previously had the final say in crafting their ad messaging, algorithms now rewrite it in real time, creating a precedent for a new wave of tensions between ad platforms and clients over who truly controls the marketing voice.

What do these terms mean?

AI Max: An AI-powered advertising system launched by Google that enables algorithms to automatically rephrase and adapt search ads to fit user queries without human intervention.

Broad Match: A targeting option in Google Ads that allows an ad to show for any search query relevant to the keyword, even if the wording differs—expanding reach while reducing precise control.

Text Customization: A feature in AI Max that gives Google the authority to automatically modify ad text to align with each search query, rather than displaying the original text written by the advertiser.
