On September 1, 2026, Google Ads begins automatically converting Search campaigns to AI Max if they currently use Automatically Created Assets or the campaign-level broad match setting. Google sent notice emails to affected advertisers on August 5. No manual action is required to trigger the switch - which is exactly the problem for accounts that have not reviewed these two settings recently.
Google holds roughly 90% search share in Ukraine, and for advertisers running lean budgets in 2026, every percentage point of wasted spend matters more than it would in a market with larger average ad budgets. A change that widens automated search term matching without a corresponding update to negative keywords can quietly erode a tight budget within days.
The Mechanics of the September 1 Change
Search campaigns with Automatically Created Assets enabled will convert to AI Max with both search term matching and text customization turned on. Search campaigns using campaign-level broad match will convert to AI Max with search term matching turned on, but without automatic text customization.
Campaigns that never enabled either setting stay exactly as they are. Google expects the full rollout across eligible accounts to be finished by the end of September 2026.
Why This Matters More for Budget-Constrained Accounts
Many advertisers managing Ukraine-facing campaigns operate with tighter cost-per-acquisition targets than advertisers in larger Western markets, simply because ad budgets are smaller relative to the competitive cost of clicks in categories like e-commerce, services, and B2B software. Automatically Created Assets and campaign-level broad match are often settings inherited from account defaults rather than choices made deliberately - meaning many active campaigns will convert on September 1 without the account manager having recently reviewed whether that is the right call.
Broader search term matching after conversion can pull in clicks adjacent to your product category rather than clicks that convert, and on a constrained budget that shift shows up quickly as a rising cost per conversion.
What Google Claims About Performance
Google reports that AI Max campaigns running the full feature combination - search term matching, text customization, and final URL expansion - see an average 7% increase in conversions or conversion value at a comparable CPA or ROAS, compared to campaigns using search term matching alone. This is internal 2026 data from Google, excluding retail advertisers, and it is an average across a global advertiser base rather than a specific forecast for your account.
For advertisers testing AI Max for the first time through this forced conversion, treat the first month as a monitoring period rather than trusting the aggregate number to apply directly to your account.
A Pre-September 1 Checklist for Ukraine-Focused Accounts
Check every active Search campaign for Automatically Created Assets and campaign-level broad match under campaign settings. Where either is on, decide in advance whether that campaign should convert or whether you want to disable the setting to opt out before the deadline.
Tighten your negative keyword lists now. This step matters even more for accounts with limited daily budgets, since broader matching without solid negative coverage burns through a constrained budget faster than it would for a larger account. The guide to AI Max negative keywords and brand exclusions walks through exactly this setup, including how to protect brand terms from being matched by unrelated queries.
This change is unrelated to the separate Dynamic Search Ads migration to AI Max, which Google pushed back to February 2027. If your account also runs DSA campaigns, track that migration as a distinct item on a different timeline.
Monitoring After the Conversion
Check the search terms report daily for the first two to three weeks after your campaigns convert, not weekly. On a limited budget, a single day of poorly matched traffic can visibly move your weekly cost-per-conversion number, so catching drift early matters more than it would for a larger account with more room to absorb variance.
Also review which AI-generated ad copy variations are being served through the Assets report, and pin approved messaging if the generated text drifts from what you intended.
Part of a Larger Automation Push
This September 1 change is the third stage of AI Max expansion in 2026. Shopping campaigns converted earlier in the year, the Dynamic Search Ads migration was announced and then pushed back to February 2027 after advertiser pushback, and now standard Search campaigns with Automatically Created Assets or broad match are being moved onto the same framework. Treat this as an ongoing trajectory rather than a single deadline to clear and forget.
For accounts managing lean budgets, building a habit of checking automation settings every quarter - not only when Google forces a change through a notification email - reduces the risk of discovering a budget-affecting shift after it has already been running for days.
FAQ
Does the September 1 upgrade apply to accounts running Ukraine-targeted campaigns?
Yes. The rollout applies globally to any Search campaign with Automatically Created Assets or campaign-level broad match enabled, regardless of which market the campaign targets.
Why does this matter more for smaller, tightly budgeted accounts?
Broader search term matching without updated negative keywords tends to increase wasted spend. On a constrained daily budget, that waste is proportionally larger and shows up in performance metrics faster than it would for an account with more budget headroom.
Is this connected to the Dynamic Search Ads migration delayed to February 2027?
No, they are separate. That delay applies only to Dynamic Search Ads campaigns. This September 1 change applies to standard Search campaigns with Automatically Created Assets or broad match enabled, and it is not delayed.
What is the most important step before September 1 for a lean-budget account?
Reviewing and expanding negative keyword lists on every campaign that will convert, since that is the single factor most likely to control wasted spend once matching broadens.
