AI Max migration is now an active operations task, not a future note. Google said on April 15, 2026 that Dynamic Search Ads, automatically created assets, and campaign-level broad match settings will auto-upgrade to AI Max in September. For D2C and growth teams, the practical implication is simple: audit legacy Search campaign setup now, because URL controls, asset behavior, and testing discipline will matter more once the upgrade window closes.
AI Max migration matters because Google is removing the option to keep certain legacy Search behaviors running indefinitely. The company says remaining eligible setups will be upgraded automatically in September, and new Dynamic Search Ads creation will end across Google Ads, Ads Editor, and the Ads API. That means teams still using DSA as a catch-all traffic layer need to understand how AI Max will decide search term matching, text customization, and final URL expansion before the change is forced.
Google reports an average 7% gain in conversions or conversion value at similar CPA or ROAS when advertisers use the full AI Max feature suite instead of search term matching alone. That is useful, but it is not a reason to migrate blindly. The real operator question is whether your account structure, landing pages, exclusions, and pinned assets are ready for the new behavior.
- AI Max Migration (Definition)
- AI Max migration is the shift from legacy Search campaign controls into Google’s AI Max system for search term matching, text customization, and final URL expansion. In practice, it changes how Google expands reach, builds ad text, and selects landing pages inside Search campaigns.
- Key Attributes:
-
- Legacy sunset: Dynamic Search Ads and related legacy controls are being phased into AI Max.
- More automation: Google will use broader signals from ads, URLs, and site content.
- More governance work: URL exclusions, brand settings, and experiments become more important.
What Google changed in the AI Max migration
Google’s update is not just a feature launch. It is an upgrade path with deadlines. The company says AI Max is moving out of beta, upgrade tools are rolling out now for DSA users, and automatic upgrades begin in September. Google also says new DSA campaign creation will stop once that automatic upgrade phase begins.
The Help Center makes the operating model clearer. AI Max can now be enabled on new or existing Search campaigns, with controls for search term matching, text customization, final URL expansion, URL inclusions, URL exclusions, and brand settings. That means AI Max migration is not just a media buying change. It is a campaign-governance change.
| Legacy setup | What Google says will happen | Operator risk | What to check now |
|---|---|---|---|
| Dynamic Search Ads | Upgrades to AI Max with standard ad groups and legacy URL controls preserved | Unexpected landing-page behavior | URL exclusions, page intent, feed hygiene |
| Automatically created assets | Upgrades to AI Max with search term matching and text customization on by default | Off-brand or weak ad copy | Text guidelines, asset review process |
| Campaign-level broad match | Upgrades to AI Max with search term matching enabled | Query drift and poor traffic quality | Brand controls, experiment design, exclusion logic |
Why AI Max migration matters for D2C search teams
Many Indian D2C teams still use Search as a blend of exact control and broad recovery. DSA often fills coverage gaps when keyword maps lag behind changing inventory, offers, or product titles. AI Max migration changes that fallback model. The system can now use broader relevance signals and more flexible asset generation, which can help scale, but it also increases the need for cleaner site structure and tighter landing-page governance.
This is where the migration becomes commercially relevant. If your category pages are messy, if your product pages are thin, or if your URLs map poorly to intent, automation will surface those weaknesses faster. Google’s own help pages note that pinned RSA assets may not be respected when Final URL expansion chooses a more relevant page. That is not a small creative detail. It affects message consistency, offer control, and compliance.
For brands that already struggle to align campaign structure, feed logic, landing pages, and lead capture, this is a strong reason to tighten systems before September. That is the same operational problem OG Marka addresses in digital transformation work: fewer disconnected layers, tighter data flow, and less manual patching after the fact.
What to audit before September in an AI Max migration
Start with the parts of the account that automation will stress first. Review URL exclusions, category-page quality, outdated or thin landing pages, pinned asset reliance, brand settings, and where legacy DSA ad groups are still doing most of the discovery work. If those areas are weak, the migration can widen inconsistency instead of improving performance.
- Pull every campaign still using DSA, automatically created assets, or campaign-level broad match settings and rank them by spend and business importance.
- Map each campaign to the URLs you actually want AI Max to use, then define URL exclusions and any brand guardrails before testing.
- Review asset logic, especially where pinned headlines or strict offer language matter, because Final URL expansion can change how ads are assembled.
- Run controlled experiments instead of switching everything at once, then judge the result on conversion quality, query fit, and landing-page relevance, not only top-line volume.
If your team lacks clean experimentation discipline, use the migration window to build it. That is more valuable than chasing AI messaging. AI Max migration is fundamentally a systems-readiness issue.
How to test the transition without hurting performance
Google recommends switching early rather than waiting for the auto-upgrade. That is the right call, but only if you preserve a baseline. Create side-by-side tests where possible, document exclusions, and track whether gains come from better query coverage or just broader traffic. If you see spend growth without stronger conversion quality, the setup still needs work.
Google says all eligible upgrades should conclude by the end of September 2026. That creates a practical deadline for account cleanup, experiment design, and stakeholder education. Teams that wait until August will be testing under time pressure.
If your Search setup depends on manual campaign workarounds, scattered landing pages, or weak catalog logic, that is usually a sign the media problem is actually a systems problem. OG Marka can help fix that through digital transformation and connected growth operations that reduce friction between ads, site structure, and conversion tracking.
