How Google’s new "AI Max" affects automotive dealership ads (and the DSA sunset).
The latest AI Max updates are set to change how dealerships manage both Search and Shopping campaigns.

From replacing Dynamic Search Ads to introducing stronger AI messaging controls, these updates reflect Google’s growing focus on automation, conversational search behavior, and AI-driven targeting.
For dealerships, these changes are important because shoppers are searching differently than they were even a year ago.
Customers are using longer, more detailed searches, and Google’s AI systems are becoming more responsible for matching ads to shopper intent.
Key takeaways:
- By September, if you’re using Dynamic Search Ads, you will need to switch to AI Max which allows for new keyword matching and automatically generated headlines and descriptions.
- As AI continues to improve and evolve in search, Dealerships should focus on improving inventory feeds, creating website content that is informative as well as customer-focused, refining campaign messaging, and maintaining accurate Merchant Center data. The better the inputs, the better Google’s AI systems can perform.
- AI is not removing the need for strategy. It is changing how strategy is applied. Dealers that adapt early and provide strong campaign guidance will be better positioned as AI-driven search continues to grow.
AI Brief gives dealers more control over AI-generated messaging.
One of the biggest updates from Google is the launch of AI Briefs within AI Max.
Previously Google allowed text guidelines around restrictions, but AI Brief will help advertisers guide how Google’s AI creates messaging and matches searches. Instead of relying entirely on automation, advertisers will now be able to review sample headlines, search queries, and audience previews before campaigns go live.
This is especially important for dealerships that need tighter control over compliance, branding, inventory messaging, and offer language.
Google also confirmed that the current text guidelines will transition into messaging guidelines inside AI Brief. This gives advertisers more influence over how AI-generated content aligns with dealership standards while still benefiting from automation.
For dealers already using AI-powered campaign types, this update creates a stronger balance between efficiency and control.
Performance Max gains Shopping text customization.
Another update includes expanded text customization for Shopping ads within Performance Max campaigns.
This creates greater alignment between AI Max for Shopping and Performance Max while maintaining access across all Google inventory, including Search, YouTube, Display, Discover, and Gmail.
For dealerships, this means more flexibility to customize messaging while still benefiting from Google’s automated campaign reach. Dealers can better tailor messaging around incentives, inventory priorities, and brand positioning without sacrificing scale.
Dynamic Search Ads are officially being sunset.
Google also confirmed that Dynamic Search Ads will officially sunset by September 2026 and transition into AI Max.
For years, Dynamic Search Ads helped dealerships capture additional traffic by automatically matching searches to website content. AI Max is now becoming the next generation of that strategy, combining automated targeting with AI-generated messaging and audience expansion.
What should dealerships do next?
All of these updates have one important thing in common. Automation is becoming more powerful, but advertiser guidance is still needed.
- Audit your inventory feeds and maintain accurate Merchant Center data. The better the inputs, the better Google’s AI systems can perform.
- Review your campaign messaging, start testing AI Max now, and provide strong campaign guidance to better position your campaign as AI-driven search continues to grow.
- Create website content that is informative and customer-focused.
