Google Is Automatically Upgrading Some Search Campaigns to AI Max. Here’s What Businesses Need to Know
Google is taking another step toward making AI the default engine behind paid search.
Starting in September 2026, Google will begin automatically upgrading certain eligible Search campaigns to AI Max for Search, according to a recent report from Search Engine Land.
The change does not affect every Google Ads campaign. But businesses currently using some of Google’s existing automation features should review their accounts before the transition begins.
Key Takeaway
- Google will begin automatically upgrading eligible Search campaigns to AI Max in September 2026.
- Campaigns using automatically created assets, now called text customization, are included.
- Campaigns using Google’s campaign-level broad match setting are also included.
- AI Max can expand which searches trigger ads and use AI to customize ad copy.
- Businesses should review affected campaigns, conversion tracking, search terms, negative keywords and brand controls before the change.
What is Google changing?
As Search Engine Land reported, Google plans to begin migrating eligible Search campaigns to AI Max starting in September.
Google has confirmed that campaigns using text customization, previously called automatically created assets, will be upgraded. Campaigns using the campaign-level broad match setting will also transition to AI Max.
This is not the same as Google automatically converting every Search campaign that happens to contain an individual broad match keyword.
Google is also moving Dynamic Search Ads toward AI Max, but that transition is on a different timeline. Google delayed the automatic DSA migration until February 2027.
What does AI Max actually do?
AI Max adds another layer of Google AI to traditional Search campaigns.
Its search term matching can go beyond an advertiser’s existing keyword list by using signals from keywords, ads and landing pages to identify additional searches Google believes are relevant.
Its text customization feature can create new headlines and descriptions based on existing ads, keywords and website content.
For campaigns currently using automatically created assets, Google says the transition will bring them into AI Max with search term matching and text customization enabled.
This is part of a much larger shift in paid advertising.
We recently wrote about this in The Algorithm Is the Media Buyer Now. Creative Is How You Talk to It. Advertising platforms are increasingly asking businesses to provide strong data, creative, landing pages and conversion signals, while their algorithms handle more of the matching and delivery decisions.
AI Max pushes Google Search further in that direction.
Why this matters for businesses
The potential upside is reach.
Google says AI Max can identify relevant searches that advertisers may not have captured through their existing keyword strategies. Google has also reported performance gains from advertisers using the technology, although individual results will naturally vary.
The tradeoff is that advertisers are giving Google more freedom to decide:
- Which searches are relevant
- Which messaging to show
- How existing campaign signals should be interpreted
That makes the quality of the inputs increasingly important.
Poor conversion tracking gives the system a poor definition of success. Weak landing pages give Google weaker signals about what the business offers. Loose negative keyword management can allow spending to move toward searches the advertiser never intended to target.
In other words, more automation does not remove the need for campaign management. It changes where that management happens.
Google’s broader use of AI across both paid and organic search reflects the same trend we discussed in AI Overviews Are Reshaping Search. Google is becoming less dependent on exact inputs and more focused on interpreting intent.
What businesses should do before the upgrade
The first step is simply identifying whether any Search campaigns are affected.
Businesses should review campaigns currently using automatically created assets/text customization or the campaign-level broad match setting.
From there, we recommend checking:
Conversion tracking. Make sure the conversions Google is optimizing toward actually represent business value.
Search term reports. Understand what traffic your campaigns are attracting now so you have a baseline for comparison after AI Max is enabled.
Negative keywords. Strengthen exclusions around irrelevant services, locations, customer types and search intent.
Ad messaging. Review headlines, descriptions and landing-page copy because AI Max can use those assets as signals.
Brand and compliance requirements. Businesses in regulated industries or those with strict messaging requirements should pay particular attention to automatically generated copy.
Performance after migration. Watch CPA, ROAS, conversion rate and lead quality rather than judging AI Max solely on additional clicks or impressions.
Google Ads is becoming less manual, not less strategic
The direction is increasingly clear.
The platforms are automating more of the technical work that once defined paid media management. The competitive advantage is moving toward better creative, cleaner data, stronger offers, accurate tracking and better decisions about what the algorithms should optimize for.
Businesses should not automatically fear AI Max, nor should they turn it on and assume Google will take care of everything.
The better approach is to understand what is changing, give the system strong inputs and measure whether the resulting traffic produces actual business results.
