The September 1 AI Max Auto-Upgrade: Your Creative Setting Just Became a Targeting Setting
The short version
Google emailed advertisers on August 5: Search campaigns using automatically created assets or the campaign-level broad match setting are automatically upgraded to AI Max starting September 1, 2026. The two groups do not get the same thing. Broad match campaigns get search term matching and nothing else, which is close to a relabel. Automatically created assets campaigns get search term matching and text customization, and that is a real change: automatically created assets only ever governed creative generation, while search term matching governs which queries you are eligible for. Google describes the upgrade as mirroring your current setup. For the ACA group it adds a targeting system that setting never had. High signal if you run ACA on Search, medium if you run campaign-level broad match, nothing to do if you run neither.
What Google announced
The notice arrived on August 5, 2026 as an email signed by "the Google Ads Team," with no accompanying blog post. Subject line: automatically created assets and campaign-level broad match setting will be upgraded to AI Max. Campaigns using either feature, or both, are automatically converted to AI Max for Search campaigns from September 1. Accounts running neither setting are unaffected.
The configurations differ by group. Per PPC Land's reporting and Search Engine Land's coverage:
- Automatically created assets campaigns upgrade with search term matching and text customization switched on.
- Campaign-level broad match campaigns upgrade with search term matching only. No text customization, and no final URL expansion, because final URL expansion depends on text customization being active.
Google's framing is that AI Max will be configured "to closely mirror the legacy setup." The email points advertisers to a pop-up banner in the interface for voluntary early upgrade, and states that the automatic upgrade can be avoided by turning the legacy features off or by enabling AI Max yourself: "We recommend transitioning to AI Max now to maintain full control over your campaign setup." There is no option that keeps automatically created assets or the campaign-level broad match setting in their current form.
One correction worth making loudly, because the trades keep merging two separate deadlines. On June 11, 2026, Google moved the Dynamic Search Ads automigration from September 2026 to February 2027, and restored DSA campaign creation on June 15. That five-month extension applied to DSA only. September 1 still stands for these two settings, and the help pages for both were never revised when the DSA date moved.
What it actually means
The broad match group is the easy call, and the honest answer is that it barely matters. Those campaigns already ran automated query expansion; the setting is being relocated into the AI Max panel rather than changed. Pinned assets in responsive search ads stay respected, because neither text customization nor final URL expansion is switched on. If you are a regulated advertiser holding compliance language in pinned positions, that is the sentence you needed. One commenter in the r/PPC thread on the email called it "basically just a rebrand and a shove into a new bucket," and for this group that reading is correct.
The automatically created assets group is a different story, and it turns on a distinction Google's "mirror" language quietly erases. Automatically created assets governed creative generation. Search term matching governs query eligibility. Those are separate layers of the account. An advertiser who ticked a box years ago to let Google write extra headlines from their landing pages did not consent to automated query expansion, because that box never offered it. On September 1 they inherit it anyway, switched on by default, unless they turn it off at ad group level. Mirroring a setup does not usually involve adding a system the setup never contained.
Two operational conditions in Google's own AI Max documentation deserve to be read together with this month's other deadline. First, Google states plainly that AI Max will not be effective if a campaign is limited by budget, and surfaces an in-interface alert when a budget-limited campaign has AI Max enabled. Search term matching widens the pool of queries you are eligible for without widening the budget that funds it. Second, as of the August 17 bid target change, budget-limited campaigns on target-based bidding now deliver to the target you typed rather than the better number you were getting. So a budget-limited ACA campaign is about to receive wider query eligibility and a stricter target inside three weeks of each other. That is the interaction to catch before September, and nobody is going to flag it for you.
There is also a trap on the way out. If you decide to switch the campaign-level broad match setting off rather than migrate, know that reverting is untidy: turning it off restores match types, but keywords that were converted while it was enabled land in a removed status and have to be reinstated at their original match types by hand. Historical statistics stay visible. If there is any chance you will revert, export your keyword list with match types now, while the original state still exists somewhere other than your memory.
On what to expect once it lands: independent measurement of AI Max has consistently run below Google's own figures. Google's April 2026 general availability claim was an average of 7% more conversions or conversion value at similar CPA or ROAS for the full feature suite versus search term matching alone, sourced to internal 2026 data excluding retail, revised down from the 14% claimed at beta launch in May 2025. Against that, an analysis of more than 250 retail campaigns in November 2025 reported conversions at roughly 35% lower ROAS than traditional match types. Neither number tells you what your account will do. Both tell you to hold a baseline rather than trust the first two weeks of dashboard.
Which is harder than it sounds, because the reporting changes shape at the same time the traffic does. The search terms report gains AI Max as a match type plus a source column distinguishing broad match expansion from keywordless matching. The keywords report adds AI Max summary rows. The landing pages report adds a "selected by" column. Those changes arrive with the upgrade regardless of which components you keep. A baseline frozen on September 2 is a baseline taken in different units than the one you needed.
Automatically created assets decided what your ads said. Search term matching decides who sees them. Google is calling the second one a mirror of the first.
Signal or noise: split by cohort
High signal if you run automatically created assets on Search. You are getting a targeting change bundled into what was a creative setting, on a default, with 25 days notice and no blog post. That is structural, and the decision about search term matching should be made deliberately rather than inherited. Medium signal if you run the campaign-level broad match setting. The behavior is largely preserved and pinning still holds; the real work is knowing the revert path is messy and exporting your match types before you need them. Noise if you run neither. The email went out broadly and confused plenty of people whose accounts have neither setting enabled. Check once, confirm, and move on.
The Monday-morning playbook
You have until September 1. The useful window is now, because a baseline taken after the upgrade is taken in different units.
- Find out which cohort each campaign is in, or whether it is in either. Check Search campaigns for the campaign-level broad match setting and for automatically created assets, now surfaced as text customization. Google Ads Editor is faster than the interface across a book of accounts. Plenty of advertisers who got the email have neither setting on; confirming that is a legitimate outcome.
- Freeze the baseline before September 1. Export search terms, keyword performance, ad and asset performance, landing pages, and CPA or ROAS by campaign. Do this now: the search terms, keywords and landing pages reports all change structure with the upgrade, so a post-hoc comparison is not comparing like with like.
- ACA cohort: make the search term matching call deliberately. It arrives on by default. It can be toggled off at ad group level, but it must be on at campaign level to be available at ad group level at all. Decide per campaign, and treat brand campaigns as a separate decision rather than a default.
- ACA cohort: decide on text customization. To turn it off, go to Campaigns, select the Settings tab, tick the campaigns you want to edit, choose AI Max, open the Asset optimization panel, and deselect the Text customization checkbox.
- Check budget-limited status on every affected campaign. Google says AI Max is not effective on budget-limited campaigns. With the August 17 target change already in force, a budget-limited campaign is getting wider eligibility and a stricter target within three weeks. Either fund it or keep search term matching off.
- Compliance and regulated accounts: audit your pins. The broad match cohort keeps pinned assets respected. The ACA cohort gets text customization, which generates headlines and descriptions from landing page content and refreshes them at least every 48 hours. If pinned copy is carrying required disclosure language, verify behavior before September 1 and look at the text guidelines pilot, which allows term exclusions up to a 25-term cap.
- Before reverting anything, export keywords with match types. Turning the campaign-level broad match setting off pushes converted keywords into a removed status; they must be reinstated at their original match types manually. The export is your only clean record of what those were.
- Agency ops. Inventory which clients sit in which cohort and put a name against each. Template the client note now: which setting they have, what switches on, what you are turning off and why, and the date you will review it. Send it before September 1, not after the first weird search term shows up.
September 1 is one of five dated Google changes landing between now and February 2027. The rest are in the deadline calendar.
The bottom line
If you run the campaign-level broad match setting, this is housekeeping: confirm, export your match types, move on. If you run automatically created assets, do not let the word "mirror" do your thinking. A creative automation setting is being used as the entry point for a targeting automation setting, on a default, announced by unsigned email with no blog post, 25 days out. That may still be the right configuration for your account. It should be a decision you make before September 1, with a baseline already frozen, rather than one you discover in the search terms report in October. The wider strategic question, what it means when the reports you would audit this with are themselves changing shape, is the subject of the companion essay on Uncommon Move: The Sealed Auction: Google Search Goes Opaque in Q3 2026.
Frequently asked
What happens to automatically created assets on September 1, 2026?
Search campaigns using automatically created assets are automatically upgraded to AI Max for Search campaigns starting September 1, 2026, with search term matching and text customization enabled by default. Automatically created assets has been renamed text customization and now requires AI Max to run at all, which is the technical reason for the migration. The addition to watch is search term matching: automatically created assets governed creative generation only, while search term matching governs which queries your ads are eligible for. Campaigns using the campaign-level broad match setting are treated differently and receive search term matching alone, without text customization or final URL expansion.
How do I opt out of the AI Max auto-upgrade?
There is no setting that declines the upgrade while keeping the legacy features. Google states that automatic upgrades can be avoided in two ways: turn the legacy features off entirely before September 1, 2026, or turn AI Max on yourself so you control the configuration. If you accept the upgrade, individual components can still be disabled afterwards. Search term matching can be toggled off at ad group level, and text customization is turned off under Campaigns, Settings, then AI Max, then the Asset optimization panel, by deselecting the Text customization checkbox.
Does the September 2026 AI Max upgrade apply to Dynamic Search Ads?
No. Google moved the Dynamic Search Ads automigration from September 2026 to February 2027 on June 11, 2026, and DSA campaign creation was restored on June 15, 2026. That five-month extension applied to Dynamic Search Ads only. The September 1, 2026 date still stands for automatically created assets and the campaign-level broad match setting, and the help pages for both settings were never revised when the DSA date moved. Two AI Max deadlines are now running in parallel and they are frequently conflated.
