DSA to AI Max Migration: What to Do Before Feb 2027
Luke Costley-White

二刀流
Two-Sword Style
Google is retiring Dynamic Search Ads. No new DSA campaigns can be created after the reopened creation window closes in January 2027, and all eligible DSA, ACA, and broad-match campaigns migrate automatically to AI Max by February 2027 (ACA and campaign-level broad match migrate sooner, by September 2026). Google claims a 7% conversion lift from the switch; independent tests show results ranging from strong gains to a 35% ROAS drop. Test before you're forced to.
If you're tracking the dynamic search ads to AI Max migration against a single date on your calendar, you're tracking the wrong one. Google has set two separate deadlines for two separate sets of campaigns, and most advertisers only know about the one that doesn't apply to them.
This isn't a one-time compliance task you clear off your list before a deadline and forget. It's a standing decision that arrives twice, with performance data that disagrees with itself depending on who ran the test. This guide covers what's actually changing, what the real numbers say, and what to do about it before either clock runs out.
What's Actually Changing, and When (The Two-Clock Problem)
Google announced the retirement of Dynamic Search Ads on April 15, 2026, with an update published June 11, 2026 (blog.google, "We're upgrading Dynamic Search Ads to AI Max"). The announcement bundles three separate campaign types into one migration, and they don't move on the same schedule.
Deadline | Applies to | Status |
|---|---|---|
September 1, 2026 | Automatically Created Assets (ACA) and campaign-level broad match | Unchanged since the original announcement |
February 2027 | Dynamic Search Ads (DSA) campaigns | Delayed once; creation window reopened June 15, 2026 through January 2027 |
The Sept 2026 Clock: ACA and Campaign-Level Broad Match
If you run standard Search campaigns with Automatically Created Assets turned on, or with broad match set at the campaign level rather than the keyword level, that migration date has not moved. It lands September 1, 2026 (Search Engine Land, Apr 15, 2026; PPC Land, Apr 15 and May 20, 2026).
The Feb 2027 Clock: Dynamic Search Ads
DSA campaigns run on a separate, later timeline, and it's already shifted once. Google originally set a September 2026 deadline for DSA too, then delayed it to February 2027 and reopened DSA campaign creation from June 15, 2026 through January 2027 (blog.google; PPC Land, Jun 13 and Jun 26, 2026). Google frames the reopened window as a deliberate side-by-side testing period before the forced migration.
Most advertisers only track one deadline and get blindsided by the other. An account running DSA in one campaign and campaign-level broad match in another is exposed to both clocks, on different dates, with different urgency.
What AI Max Actually Replaces, and What It Doesn't
AI Max bundles three features into existing Search campaigns: keywordless search term matching, AI-generated text customization, and final URL expansion. DSA only ever did one of those three jobs.
The Feature That Replaces DSA
Final URL expansion is the direct successor to DSA. It lets Google route traffic to whichever page on your site it judges most relevant, the same core mechanic DSA used to crawl your site and match queries to landing pages. Search term matching and text customization are new capability layered on top, not a replacement for anything DSA did.
Why Side-by-Side Testing Doesn't Work the Way You'd Expect
Google's own reopened creation window implies you can run DSA and AI Max side by side to compare them. In practice, that comparison breaks down inside a single account.
SavvyRevenue tested this directly and found AI Max generated just 72 clicks out of more than 3,000 total, while a DSA campaign was still active in the same account. Once DSA was paused, AI Max activity increased sharply, effectively "taking over" the volume DSA had been driving (savvyrevenue.com, "DSA to AI Max: A Pragmatic Guide to Migrating Without Breaking Your Account," Jun 5, 2026).
The two systems appear to compete for the same auctions, and Google's own account logic suppresses AI Max while DSA is live. A meaningful test means pausing DSA first, not running both at once.
Google's Performance Claim vs. What Independent Testing Shows
The 7% Figure, and What It Actually Measures
Google's headline number has already moved once. At AI Max's May 6, 2025 launch, Google claimed a 14% lift in conversions or conversion value. In the April 15, 2026 retirement announcement, that figure was revised down to 7%.
The 7% claim carries three qualifiers worth knowing before you cite it internally:
It excludes retail advertisers.
It compares the full AI Max feature suite against search-term-matching alone, not against DSA as a whole.
It's footnoted as "Google internal data, 2026," with no published methodology.
The Independent Data
Four separate independent tests, run by different practitioners in different accounts, tell a less tidy story than Google's single figure:
Ezra Sackett, Director of Paid Search at Monks, found 99% of roughly 30,000 AI Max-expanded search terms generated zero conversions (ppc.land, Aug 17, 2025).
An independent study across 250+ retail campaigns found AI Max delivered roughly 35% lower ROAS than traditional match types (ppc.land, Nov 8, 2025).
Xavier Mantica's four-month test in a single account found AI Max cost $100.37 per conversion against $43.97 for phrase match, in the same account, over the same period (ppc.land, cited Apr 15, 2026).
A separate study from Smarter Ecommerce (Mike Ryan) found a median +13% revenue lift paired with +16% higher CPA, and ROAS swinging from +42% to -35% depending on the account (digitalapplied.com, "Google Delays the DSA-to-AI-Max Migration to Feb 2027," Jun 14, 2026).
None of this makes Google's 7% figure wrong. It makes it one data point among several, with the largest independent samples showing far more variance than a single average implies. Treat both Google's number and the independent numbers as directional, not decision-grade, until you've run your own test in your own account.
What to Actually Do Before Your Deadline Hits
Before September 2026, If You Run ACA or Broad Match
Run a brand exclusion audit. Keywordless matching under AI Max can surface queries you'd never manually target, including competitor and brand-adjacent terms.
Refresh your negative keyword list. This is your primary lever once matching broadens beyond your keyword set.
Decide on final URL expansion explicitly. It's on by default. If your site has thin pages or inconsistent messaging, set URL exclusions before the switch, not after.
Set text customization guidelines now. Expanded text controls give you more structured input on brand voice and what the AI avoids generating, but only if you configure them before the migration runs.
Before February 2027, If You Run DSA
Pull a 90-day performance baseline from your current DSA campaigns: cost per conversion, conversion rate, and which landing pages actually convert.
Audit your conversion tracking. Any test you run against that baseline is only as good as the tracking underneath it.
Run an isolated test, not a side-by-side one. Based on the SavvyRevenue finding above, pause DSA in a controlled test account or ad group before turning on AI Max. A concurrent test will understate AI Max's actual behavior.
Use the reopened creation window deliberately. It closes in January 2027. Treat it as your last window to compare a real DSA campaign against a real AI Max campaign, not as extra runway to delay.
If You're Exposed to Both Deadlines
Sequence September first. The brand exclusion and negative keyword work you do for ACA and broad match carries directly into your DSA test, since both run on the same keywordless matching engine underneath.
The Open Questions Google Hasn't Answered
Two practical questions remain genuinely unresolved, and Google has not addressed either directly.
Mixed campaigns. Many accounts run standard keyword ad groups alongside DSA ad groups in the same campaign. Whether the forced migration touches the entire campaign or only the dynamic ad groups within it is an open question raised by practitioners, including Joao de Braganca in a LinkedIn discussion covered by ppc.land. Until Google clarifies this, don't assume either outcome.
Historical DSA reporting. What happens to your existing DSA performance history once a campaign migrates, whether it stays queryable in the same reports or gets siloed, is also unclear. If year-over-year DSA reporting matters to your team, flag this now rather than discovering a gap after the migration runs.
Why This Needs Monitoring, Not Just a One-Time Checklist
Treating this migration as a pre-deadline scramble misses the actual shape of the problem. Google has already moved the DSA deadline once. The feature set changes underneath advertisers with little warning, and the independent data above shows performance swinging from +42% to -35% ROAS across otherwise comparable accounts.
That's not a one-time audit problem. It's a continuous account-hygiene problem: search-term drift as keywordless matching expands, CPA against your baseline as Google's models keep training, and negative-keyword coverage as new query patterns surface. A quarterly check misses the account that drifted 20% off baseline in week three.
This is exactly the kind of standing problem an AI marketing intelligence system like DOJO is built to sit on top of: continuous cross-account tracking of search-term drift and CPA against baseline, catching the erosion before it shows up in a monthly report instead of after.
FAQ
Do I need to do anything before September 2026 if I only run Dynamic Search Ads? No. DSA's deadline is February 2027, not September. But check whether you also run ACA or broad-match settings elsewhere in the account, since those follow the earlier deadline and are easy to miss if DSA is your main focus.
Can I still create new DSA campaigns right now? Yes. Google reopened DSA campaign creation from June 15, 2026 through January 2027, specifically to give advertisers a testing window before the forced February 2027 migration.
Will my negative keywords still work once AI Max is active? Yes. Google confirms negative keywords are respected under AI Max, but they carry more relative weight than before, because AI Max's broader keywordless matching means negatives are one of the few direct controls left on what your ads match to.
Does AI Max actually perform better than DSA? Google claims a 7% lift. Independent data is mixed, ranging from real gains to double-digit ROAS declines depending on the account and vertical. Treat it as untested in your account until you run your own isolated comparison.
If your account is exposed to either deadline, the dynamic search ads to AI Max migration is worth testing on your own terms now, while the reopened creation window is still open, rather than finding out what changed after Google migrates it for you.
