Google Auto-Upgrades Broad Match Campaigns to AI Max

Google began automatically converting Search campaigns that use campaign-level broad match or automatically created assets into AI Max on September 1.

If you run a high-ticket store and either setting is switched on, Google is changing how your ads get matched to search queries this month and you did not have to approve it. Campaigns that had automatically created assets enabled come out the other side with search term matching and text customization both on by default. That is query expansion plus AI-written headlines, on a store where one order can be worth $3,000.

The migration window closes September 30. Most store owners I have talked to this week did not know their accounts were in scope, and a few found out because their search terms report started filling up with queries they never bid on. Here is what actually changed, what Google promised, what independent testing found, and what I would do about it before the month ends. If you are newer to this model, my guide on what high-ticket dropshipping actually is covers why paid search carries so much weight in this business, and Ecommerce Paradise has the rest of the paid traffic material.

Google can rewrite your campaign settings overnight. Your registered agent should not be the other thing that changes under you.

Google Started Migrating Broad Match and ACA Campaigns Sept. 1

The migration covers two legacy Search settings. Campaigns using the campaign-level broad match setting, and campaigns using automatically created assets, the feature Google now calls text customization. According to Search Engine Land’s timeline, the upgrades roll out gradually across the full month and finish by September 30.

The two groups do not get the same configuration. Per PPC Land’s reporting on the notification email, campaigns with automatically created assets are upgraded with search term matching and text customization enabled by default. Campaigns using the campaign-level broad match setting get search term matching only, without text customization or final URL expansion.

That distinction matters more than it looks. Automatically created assets governed creative generation, meaning headlines and descriptions written from your landing page content. Search term matching governs which queries your ad is eligible for at all. So a store that opted into automated ad copy is now also opted into automated query expansion, which is a different decision entirely and one nobody made on purpose.

Google says the upgrade happens in place. AI Max is a setting on an existing Search campaign rather than a new campaign type, so campaign IDs, names and structure carry through. Existing brand inclusions and exclusions carry over automatically as well.

The dates are firm and they were set weeks ago. On August 3, Google stopped allowing creation of new campaign-level broad match configurations and legacy automatically created assets campaigns across the Google Ads interface, Ads Editor and the API, a freeze Google spelled out for developers on its Ads Developer Blog. On August 5, Google emailed affected account holders confirming the September 1 start, a message signed by the Google Ads Team with no accompanying blog post. Automatic upgrades then began September 1.

Dynamic Search Ads are not in this window. Google moved DSA automigration to February 2027 on June 11 after advertisers raised fourth-quarter planning risk, and that extension applied to DSA only. The help pages for both affected settings kept the original September date.

Opting out is possible and it is per feature. Google’s own setup documentation walks through toggling AI Max off in campaign settings or disabling individual features. One detail worth knowing before you try: search term matching must be on at campaign level before it can be used at ad group level, so an opt-out done only in ad groups leaves the campaign setting live. Text customization and final URL expansion are campaign-level controls.

How the 14% AI Max Promise Became 7% and Excluded Retail

AI Max entered open beta on May 6, 2025 with a claim of 14% more conversions or conversion value at similar cost. When Brandon Ervin, Director of Product Management at Google Ads, declared the product out of beta on April 15, 2026, the announcement carried a smaller number: an average of 7% more conversions or conversion value at a similar CPA or ROAS, measured across the full feature suite compared with search term matching alone.

Read the footnote on that figure. It is Google internal data from 2026, and it excludes retail advertisers. Google published a lift number for AI Max and then carved out the exact category most of my readers sell in.

Independent testing has landed somewhere else. In August 2025, Ezra Sackett, Director of Paid Search at Monks, reported that 99% of AI Max impressions produced zero conversions across roughly 30,000 search terms in client accounts. That same month analysts flagged AI Max expansion onto Search Partner Network placements, where Intelligency Group research had found return on ad spend 37% below Google Search proper. In November 2025, an analysis of more than 250 retail campaigns found AI Max delivering conversions at roughly 35% lower ROAS than traditional match types.

Google’s answer has been controls rather than retreat. Branded search controls arrived inside AI Max in May 2026. AI Brief, a plain-language instruction layer, launched April 30 alongside text disclaimers for final URL expansion. The same day AI Max reached standard Shopping campaigns, which I covered when it happened in this breakdown of AI Max hitting Shopping.

There is a real counterpoint here and it deserves stating. For the broad match cohort, this is close to a relocation. Those campaigns were already running every keyword as broad match under Smart Bidding, and search term matching alone does not add text customization or landing page rerouting. Practitioners in the r/PPC thread that followed the August email described it as a rebrand into a new bucket, and for that group they are mostly right. The ACA cohort is the one taking on genuinely new behavior.

Worth noting the direction of travel is not Google-specific. Microsoft retired Predictive Matching into its own AI Max product in July 2026, absorbing keyword expansion into an automation layer the same way.

What AI Max Search Term Matching Costs a High-Ticket Store

My read is that this change is priced differently depending on your average order value, and high-ticket sits on the wrong end of that.

Run the math. If you sell a $2,800 pellet grill line at a 22% gross margin, you have about $616 of gross profit per order to spend against. At a 15% blended cost of sale you are working with roughly $420 of ad budget per sale and a click cost somewhere between $2 and $6 depending on the vertical. Query expansion that adds 200 wasted clicks a week at $4 costs you $800, which is two orders of gross profit gone before anything converts. On a $40 product that same expansion is an annoyance. On mine it is the month.

The second problem is measurement. Google’s reporting adds a source value to the search terms report distinguishing keyword-driven traffic from AI Max broad match and from keywordless matching, which is traffic matched off page and asset content with no keyword involved at all. That column is not in the default view. You have to add it. Until you do, wasted spend from expansion looks like ordinary campaign spend in every report you already run.

There is also a filter trap. Google warns that filtering the search terms report by match type “AI Max” can show lower numbers because the filter does not count “Other search terms.” So the one number a store owner would naturally pull to size the damage is the number that undercounts it.

Third, final URL expansion can send traffic to a different page than the one configured on the ad. It only applies by default to the ACA cohort if that feature gets switched on later, but when it is active, tracking templates built around fixed destinations can break. Nonstandard URL constructions can produce 404s. If you have ever fought with tracking on this platform, my post on Google turning every Google tag into a GTM container covers the other half of that headache.

Fourth, and this is the one I would flag to any client on a tight budget: Google states plainly that AI Max will not be effective on a campaign that is limited by budget. Search term matching widens the pool of queries you are eligible for without widening the money that funds them. A $60-per-day campaign that suddenly qualifies for three times the query surface does not get better results, it gets thinner ones.

None of this makes AI Max unusable. I have accounts where expanded matching found buyer queries our keyword lists never would have. What it does is move the work. Instead of building keyword lists you are now building negative keyword lists, reading a source column that did not exist last month, and reconciling landing page data that no longer matches what is on the ad. That is more account management, not less, at exactly the moment Google is describing this as a simplification.

If reading that paragraph made you tired, that is the honest reaction. Running Google Shopping and Search properly for a high-ticket store is now a job, not a weekend setup. My team does this build and this ongoing management for store owners who would rather sell than sit in Google Ads all week, and you can see how the turnkey done-for-you store build and management service works if that is where you are at.

How to Audit Your Google Ads Account Before Sept. 30

Five things, in the order I would do them.

Find out which campaigns are actually in scope. Because the creation freeze landed August 3, the affected set is fixed and countable. Open each Search campaign, check whether the campaign-level broad match setting or automatically created assets was enabled, and write the list down somewhere durable. In three months you want to be able to answer whether a change was yours or Google’s.
Add the Source column to your search terms report today. Default views do not show it. Once it is there, segment by source and watch the keywordless bucket. If it starts absorbing meaningful spend inside two weeks, you have your answer on whether to opt out. Pair it with a proper keyword tool like SEMRush so you are comparing Google’s expansion against what real buyer intent looks like in your niche.
Rebuild your negative keyword list before the expansion arrives, not after. Weak negatives get expensive fast under search term matching. Pull 90 days of search terms, strip out every research, parts, repair, used, rental and DIY query, and push those in as phrase-match negatives. KWFinder is cheap and fast for finding the adjacent junk terms you have not seen yet, and if you would rather not spend a day on it, this is exactly the kind of task I hand to a VA hired through OnlineJobs.ph.
Check your budget-limited status on every migrated campaign. Google’s own documentation says AI Max will not perform on a budget-limited campaign, and an alert appears in the interface when that happens. If a campaign is capped, either raise the budget or turn search term matching off. Running both at once is how accounts quietly bleed.
Decide opt-in or opt-out per campaign and record the decision. Do not let September 30 make the choice for you. If you want a second set of eyes on your specific account before you flip anything, that is what my one-on-one coaching is for, and I would rather look at it now than reconcile a bad Q4 in January.

Two more things that are not urgent but are worth doing this month. Make sure your phone number is on every product page, because when paid traffic gets noisier the phone is what saves the sale, and a line through Grasshopper costs less than one wasted click day. And get your email capture working properly, because traffic you paid for once should not cost you twice. I run Omnisend on my own stores for that.

Frequently Asked Questions

Does this apply to my Shopping campaigns?
Not this migration. The September window covers Search campaigns using campaign-level broad match or automatically created assets. AI Max reached standard Shopping campaigns separately back on April 30, 2026.

What if I never turned on either setting?
Nothing happens to your account. The migration only touches campaigns that had one or both legacy features enabled, and you can confirm that in campaign settings in about two minutes.

Can I opt out after September 30?
You can turn AI Max off in campaign settings at any point, and Google says re-enabling later restores the feature-level settings you had before. The reason to act inside the window is that you keep control of the configuration instead of inheriting a default.

Will my Dynamic Search Ads campaigns be migrated too?
Not until February 2027. Google extended that deadline on June 11, 2026, with in-account notices starting this month and reminders on January 15, 2027.

Is AI Max worth running on a high-ticket store?
Test it, do not adopt it blindly. Google’s 7% lift figure excludes retail advertisers and independent tests on retail campaigns have reported roughly 35% lower ROAS, so the honest position is that it depends on your niche and your negative keyword hygiene.

Where do I even start if I am building a store from scratch right now?
Pick a vertical first. My high-ticket niches list is the fastest way to shortlist one, and then work through the supplier sourcing guide before you spend a dollar on ads.

Do I need an LLC before I run paid traffic at this level?
Yes, and it is cheap insurance once you are moving $50,000 a month through a merchant account. Bizee handles the filing inexpensively, and my post on business licenses covers what else your state may want.
