Google Is About to Auto-Upgrade Your Search Campaigns to AI Max. Here Is What Actually Changes.

On August 5, Google emailed advertisers a quiet but consequential notice: starting September 1, Search campaigns using automatically created assets or the campaign-level broad match setting get converted to AI Max, whether anyone logs in to approve it or not. If you don't recognize either setting by name, you might still be affected without knowing it, and what actually changes depends on which one your account has switched on.

What Actually Triggers the Upgrade

This isn't a blanket upgrade of every Search campaign in existence. It specifically targets two legacy settings: automatically created assets, where Google generates additional headlines and descriptions on your behalf, and the campaign-level broad match setting, an older way of applying broad match across an entire campaign at once. If neither setting is switched on in your account, nothing changes on September 1. If either one is, the campaign gets folded into AI Max automatically, and the outcome depends on which setting it was.

The Outcome Isn't the Same for Everyone

The practical difference is significant. A campaign built on automatically created assets ends up with the fuller AI Max feature set, including Google rewriting landing page destinations and generating new ad copy on its own. A campaign running on the older campaign-level broad match setting gets a narrower version, matching alone, without the more aggressive creative and URL changes. Advertisers who assume "AI Max" means the same thing everywhere are likely to be surprised by which campaigns behave differently after September 1.

How to Stay in Control of the Timing

1. Check whether either legacy setting is actually on before assuming you're affected. Plenty of accounts have neither switched on and won't see any change at all.
2. Turn off the legacy setting if you want to delay the migration and evaluate AI Max on your own schedule instead of Google's.
3. Or opt in manually now, on a campaign you're comfortable testing with, so you control which account is first to feel the transition rather than having it apply everywhere at once on September 1.
4. Review pinned assets and landing pages beforehand if your account uses automatically created assets, since that's the group getting the fuller set of AI-driven changes.

Google has been steadily consolidating its automated campaign types under the AI Max and Performance Max umbrellas for over a year now, and this auto-upgrade is a continuation of that pattern rather than a one-off change. If your account structure hasn't had a proper review since before these settings existed, it's worth having someone confirm what will actually change on your account before September 1 rather than after. Our Google Ads management team audits exactly this kind of setting drift as a standard part of taking over an account.
