Starting today, September 1, 2026, Google Ads begins automatically moving eligible Search campaigns onto AI Max, and the rollout continues in stages through the rest of the month. If you run Search campaigns for a US brand, your account may be upgraded on any day in September rather than all at once, so the practical task right now is to know which campaigns qualify, what the upgrade touches, and which settings deserve a second look before the change reaches you.
Key takeaways (30-second version)
- Timing: Automatic upgrades to AI Max for eligible Search campaigns begin September 1, 2026, and roll out progressively through the month.
- Not simultaneous: Accounts are migrated in waves, so two brands can see the change land on different days in September.
- DSA sunset: Dynamic Search Ads are entering their sunset this month, with eligible campaigns folding into AI Max.
- Review, don’t panic: The smart move is auditing targeting, URL, and creative settings before the upgrade reaches your account.
- Keep watching after: Migration is a starting point, not a finish line, so post-upgrade monitoring matters as much as prep.
1. What actually changes today
AI Max is Google’s bundle of AI-driven features for Search campaigns, aimed at broadening how ads match to queries and how creative assets are assembled. Until now, moving an existing Search campaign onto it was largely an opt-in decision. As of September 1, 2026, that shifts: Google begins upgrading eligible campaigns on its own, and it plans to work through the eligible population over the course of the month.
The word “progressively” is doing real work here. This is not a single overnight switch for every advertiser. Google is running the migration in waves, which means the day your account changes may not be the day your competitor’s account changes. For agencies and in-house teams managing multiple accounts, that staggering is a scheduling detail worth respecting, because you cannot assume all your properties will move together.
What that means in plain terms: check your accounts more than once this month, not just on the first. An account that looks untouched on September 2 could be upgraded by September 20.
Why this matters: A staggered rollout removes the comfort of a single “migration day.” The accounts you audit early may still be waiting, and the ones you assume are safe may already have changed. Treat all of September as the window.
2. Which campaigns get upgraded, and when
The upgrade applies to eligible Search campaigns. Eligibility is Google’s determination, so the honest answer for any given account is that you should confirm inside the platform rather than assume. The mechanics that Google has stated publicly are straightforward enough: the process starts today and continues through September 2026, campaign by campaign, rather than in one sweep.
For US advertisers, the accounts most worth watching closely are the ones with active, spending Search campaigns where a change in matching behavior could move volume or cost quickly. A dormant campaign shifting to AI Max is low stakes. A high-spend brand or non-brand campaign changing how it matches queries is a different conversation, and that is where your attention belongs.
| What we know | Detail | Confidence |
|---|---|---|
| Start date | September 1, 2026 | Confirmed by Google’s announcement and industry reporting |
| Rollout style | Progressive, across the month of September 2026 | Confirmed |
| Scope | Eligible Search campaigns | Confirmed, with eligibility set by Google per account |
| DSA path | Dynamic Search Ads sunsetting, eligible campaigns upgrading to AI Max | Confirmed for September 2026 |
| Exact default settings on upgrade | Targeting, URL expansion, and creative defaults | Not independently corroborated. Verify in-account. |
That last row is the one to be careful about. There has been discussion about how specific settings, such as URL expansion and text customization, will be configured when a campaign is auto-upgraded. Those specifics are not independently confirmed at the level of a public, cross-checked fact, so the responsible approach is to read them from your own account settings once the upgrade lands rather than to trust a secondhand summary.
3. The Dynamic Search Ads sunset
Alongside the AI Max rollout, Dynamic Search Ads are entering their sunset in September 2026. DSA has been the long-standing way to let Google generate headlines and match to queries based on a site’s content rather than a fixed keyword list. According to Google’s announcement, eligible DSA campaigns are upgrading to AI Max as part of this transition.
If you have leaned on DSA to cover the long tail of search demand, this is the change that likely affects you most. The conceptual overlap is clear: both DSA and AI Max lean on Google’s systems to reach queries you did not explicitly enumerate. The transition is meant to carry that function forward inside AI Max. Still, a feature sunset is a good moment to re-examine whether the coverage DSA gave you is actually being reproduced, and at what cost, once the campaign moves.
Why this pairing makes sense
Folding DSA into AI Max consolidates two AI-assisted matching approaches into one framework. For advertisers, the takeaway is not to mourn DSA but to verify continuity: confirm that the pages, themes, and query space DSA was covering are still covered after the upgrade, and that your negative keyword and brand protections carried over the way you expect.
4. Settings worth reviewing before the upgrade
Because the exact post-upgrade configuration of certain controls is not something we can state as verified fact, the best use of your time is a pre-upgrade audit of the settings you already control. None of this requires guessing what Google will do. It is simply making sure your account is in a known state before the change arrives.
Targeting and match behavior
Document how your current campaigns match today: keyword match types, negative keyword lists, and any brand exclusion lists you rely on. If matching broadens under AI Max, your existing negatives are your first line of defense against irrelevant traffic. Knowing exactly what they contained before the upgrade lets you tell whether anything shifted after.
Final URLs and landing pages
AI-driven features can influence which landing page a query is sent to. Before the upgrade, confirm that the URLs you want to serve are the ones configured, and note whether any URL expansion setting is currently on or off. After the upgrade, check the same setting again. If it changed, you will want to make a deliberate decision rather than inherit a default.
Creative and text assets
Review your headlines, descriptions, and any assets that might be automatically customized. Make sure the copy in your account reflects claims you can stand behind, especially for regulated or sensitive categories. If text customization is applied, you want your source assets to be strong enough that any generated variation stays on-brand and compliant.
Conversion tracking and budgets
A matching change can move volume, and volume moves spend. Confirm conversion tracking is healthy and that budgets and bid strategies are set at levels you are comfortable with if traffic composition shifts. This is basic hygiene, but it is exactly the kind of thing that gets overlooked during a platform transition.
5. A practical playbook for September
Here is a simple sequence that works for a single brand or a portfolio of accounts, built around the fact that the rollout is staggered.
First, baseline before the change. Export or screenshot current settings and recent performance for each active Search campaign now. When an upgrade lands mid-month, a clean before-picture is what lets you separate a real effect from normal week-to-week noise.
Second, check on a schedule, not once. Since accounts migrate in waves through September, build in repeated checks. A quick look every few days across the month beats a single audit that misses a late upgrade.
Third, read the settings the day the upgrade lands. When you see a campaign has moved to AI Max, open its targeting, URL, and creative settings and confirm each one matches your intent. Do not assume the defaults are what you would have chosen.
Fourth, watch the query and search-term data closely for a week or two after. This is where a broadened matching behavior shows up first. Fresh negatives and brand exclusions are your steering wheel if the traffic mix drifts.
Fifth, judge on outcomes, not fear. The goal is efficient, relevant volume. If AI Max delivers that, good. If the search-term report shows waste, tighten with negatives and revisit URL and text settings. Let the data, measured against your baseline, make the call.
6. Frequently asked questions
Q1. When exactly does the AI Max auto-upgrade start?
Google begins automatically upgrading eligible Search campaigns to AI Max on September 1, 2026. The rollout then continues progressively through the rest of September, so not every eligible campaign moves on the first day.
Q2. Will all my campaigns be upgraded at the same time?
No. The migration runs in waves across the month. Different accounts, and different campaigns within an account, may be upgraded on different days in September, which is why checking repeatedly through the month is worthwhile.
Q3. What happens to my Dynamic Search Ads?
Dynamic Search Ads are entering their sunset in September 2026, and according to Google’s announcement, eligible DSA campaigns are upgrading to AI Max. If you relied on DSA for long-tail coverage, confirm that coverage continues after the transition.
Q4. Will my URL expansion and text customization settings change automatically?
The precise configuration of settings like URL expansion and text customization on auto-upgrade is not something we can confirm as an independently verified fact. The reliable approach is to read those settings directly in your account before and after the upgrade and adjust them to match your intent.
Q5. What should I do before my account is upgraded?
Baseline your current settings and performance, review negative keyword and brand exclusion lists, confirm your final URLs, check your creative assets for compliance, and make sure conversion tracking and budgets are in a state you are comfortable with if volume shifts.
Q6. Can I tell whether the upgrade helped or hurt?
Yes, if you captured a baseline first. Compare post-upgrade search-term relevance, cost, and conversion outcomes against your pre-upgrade numbers. Use negatives and setting adjustments to correct any drift, and judge the change on measured results rather than on the switch itself.
7. The bottom line
The change that starts today is real, but it rewards preparation over alarm. Eligible Search campaigns move to AI Max on a rolling basis through September 2026, Dynamic Search Ads sunset into the same framework, and a handful of setting-level specifics are best confirmed inside your own account rather than taken on faith. Baseline now, check often, read your settings when the upgrade lands, and let the search-term data guide your adjustments.
If you would rather have a team watch the rollout across your accounts and tune the settings as each upgrade lands, that is the kind of hands-on account work Calywire handles for the brands we support. Either way, the playbook above will carry you through the month.
