Google Is Changing Your Ad Campaigns This Month Whether You Log In or Not
Between September 1 and September 30, Google is automatically moving Search campaigns that used campaign-level broad match or automatically created assets into a system called AI Max. If your campaigns used automatically created assets, the upgrade also switches on text customization, which lets Google rewrite parts of your ad copy. Nobody is going to call you about it. Google's own advice is to review your settings after the upgrade, and the public reporting does not describe a way to refuse it, so the useful move this month is to log in and look at what changed.
The change that is happening right now
On August 3, Google stopped letting advertisers create new campaign-level broad match settings and new standalone legacy automatically created assets. Those were two older ways of giving Google room to expand who saw your ads and what those ads said.
Campaigns that already used either one are now being upgraded automatically. Search Engine Land reported the timeline on August 14: the migration runs from September 1 to September 30 and rolls out gradually, which means some accounts may already have moved and others will move before the month is out.
The destination is AI Max, Google's current bundle of machine learning features for Search campaigns. Two things about your account can change in the process: which searches your ads match to, and, for one group of advertisers, the words the ad actually shows.
| Date | What happens |
|---|---|
| August 3, 2026 | No new campaign-level broad match settings or new standalone legacy automatically created assets can be created |
| September 1 to 30, 2026 | Existing campaigns using either are auto-upgraded to AI Max, gradually across the month |
| September 2026 | Creation of new Dynamic Search Ads campaigns ends |
| February 1 to 28, 2027 | Dynamic Search Ads are auto-upgraded, pushed back from an original date of around September 2026 |

The two groups, and why one should pay closer attention
Reporting from August 6 splits the migration in two, and the split is the part that matters.
| If your campaign used | It is upgraded with |
|---|---|
| Automatically created assets | Search term matching and text customization, enabled by default |
| Campaign-level broad match | Search term matching, enabled |
Google says campaigns are migrated in place using equivalent AI Max settings, and that existing brand inclusions and exclusions carry over automatically.
Text customization is the one to look at first, because it is the feature that touches your words. For a local service business, the headline in a search ad is often the first thing a customer ever reads about you. If a generated version of that line overpromises, or simply does not sound like your business, your name is still the one attached to it, and you are the one taking the call from a customer who expected something else.
The other group has the lighter change. Ad text stays as written, and what shifts is the matching behaviour that decides which searches can trigger the ad.
One word in Google's description deserves attention. Campaigns are migrated using equivalent settings. Equivalent is not identical. It means Google chose the nearest thing it has to what you were running, and the nearest thing can behave differently once it is live on your budget.
The public reporting on this migration does not describe an opt-out or a revert path, and I am not going to invent one. Google's stated recommendation is that advertisers review campaign settings after the upgrade to understand which AI features have been enabled. Treat this as something to inspect and respond to, not something to decline.
What is in the bundle, and how to read Google's number
AI Max is not a single switch. Google names three parts: search term matching, text customization, and final URL expansion. The migration reporting names only the first two as switched on by the upgrade.
Google publishes a figure for running all three. Its claim is that AI Max for Search campaigns see an average of 7 percent more conversions or conversion value at a similar CPA or ROAS when using the full feature suite, compared to using search term matching alone. The attribution on that number is Google internal data from 2026, for non-Retail advertisers.
That is a vendor measuring its own product on a subset of advertisers, which does not make it wrong. It makes it the same kind of number as any figure in a sales deck: useful as a direction, not as a forecast for your account. If you run a Retail account, note that the figure was not measured on accounts like yours.
The check to run on your account this month
If you have a Google Ads account and have not opened it since August, this is under an hour of work on a small account.
Start by working out whether your campaigns were migrated at all. Open the settings on each Search campaign and look for the AI Max features by name. If search term matching or text customization are listed there, the upgrade has reached you.
Then note which of those features are switched on, campaign by campaign. Text customization is the one to write down. If it is enabled and you never chose it, look at the ad copy actually being served before you decide how you feel about it.
After that, verify the protections you already had. Google says brand inclusions and exclusions carry over, and the sensible response to any vendor saying something carried over is to open the list and confirm it. Check your negative keywords are still present. Check any brand exclusions survived. A brand exclusion that quietly went missing is how an account starts paying for competitor-brand searches, and that gets expensive faster than most owners expect.
Dynamic Search Ads bought you time
One piece of this got easier. Dynamic Search Ads were originally lined up to migrate around September 2026, and Google pushed that back. Automatic DSA upgrades now begin in February 2027, with a migration window of February 1 to 28. Creating new DSA campaigns still ends in September 2026.
That is roughly five months of runway on the DSA side, and it is better spent than banked. If one of the campaigns Google migrates this month is low stakes, a secondary service line or something with modest spend, use that one as your test case: watch what changes in its settings and in the copy it serves, and carry that list into February when your DSA campaigns come up.
On the organic side, a new report with one big gap
The advertiser tools were not the only thing that moved. On August 31, Google finished rolling out Search Console's generative AI performance reports and its generative AI control to every site worldwide, reported the same day.
The report gives you impressions, pages, countries, devices and dates for your site's appearances in Google's generative AI surfaces, covering AI Overviews and AI Mode along with generative AI features in Discover. You can see which of your pages are being surfaced inside AI answers and where those appearances come from.
What it does not give you is clicks. The report has no click data at all, which sets a firm limit on what you can conclude from it. It tells you that Google showed your page inside an AI answer. It cannot tell you whether that turned into a visit.
Keep that in mind before reading a rising line as good news. If generative AI impressions climb while your site traffic stays flat, the report is doing its job: it counts appearances, and only your analytics counts visits.
The control that lets you leave AI answers
Shipping alongside the report is a control that lets site owners decide whether their site should appear in and help ground responses in Google's generative AI Search features.
Google states that this control will not be used as a ranking signal for search results outside of these generative AI Search features, so it should not negatively impact a site on core web search.
My read for most small local businesses is to leave it alone. Being cited in an AI Overview is one of the ways a customer finds you now, and opting out removes you from those answers while doing nothing for the rest of your search presence. There are publishers with a genuine argument for using it. A plumber in Bedford County is not usually one of them.
A smaller change, for anyone hosting other people's content
One more landed at the end of August, and it is narrow. Google updated its site reputation abuse policy and now enforces it differently depending on region, following discussion with the European Commission.
From August 30, outside the European Economic Area, manual actions affect the violating section of a site. Inside the EEA no manual action affects rankings, and Google may instead separate the affected section from the rest of the site in its systems so that it eventually ranks on its own merits.
Google also replaced its previous examples with four factors it now weighs, covering how the content is presented, its quality relative to the main domain, and its stated authorship. For most small businesses this is background. It becomes relevant the moment you rent a section of your domain to somebody else or run sponsored content that lives on your site, and the factor that catches people out is presentation: a section that looks nothing like the rest of the site is now something Google explicitly weighs.
What to do before October
Open Google Ads. Find out whether your campaigns moved. Note which AI features are switched on, and give text customization a closer look than the rest. Confirm your negatives and brand exclusions came through intact.
Then open Search Console and look at the generative AI report, remembering that the impressions in it are not visits.
Google set the date for all of this months ago and is keeping to it. The only person who finds out what changed on your account is the one who goes and looks.
