Google confirmed on August 5, 2026 that it will begin converting Search campaigns to AI Max automatically starting September 1. The trigger is not a manual choice by the advertiser - it is based on two existing campaign settings: Automatically Created Assets and campaign-level broad match. Any advertiser worldwide running either setting will see their campaign structure change.
Google expects the rollout to finish by the end of September. Campaigns that never used these two settings stay untouched. Everything else described in this article applies specifically to accounts where at least one of them is currently active.
Two Settings, One Trigger
The upgrade logic is simple but easy to miss. If a campaign has Automatically Created Assets switched on, Google converts it to AI Max with search term matching and text customization enabled by default. If a campaign uses the campaign-level broad match setting instead, Google converts it to AI Max with search term matching enabled, without automatically turning on text customization.
Both settings have existed for years and were often enabled as part of account setup defaults rather than a deliberate strategic decision. That gap between "technically enabled" and "actively managed" is exactly why this rollout catches many advertisers by surprise.
Not the Same Timeline as the DSA Migration
Google previously announced that Dynamic Search Ads campaigns would move to AI Max, then pushed that specific migration back to February 2027 after advertiser pushback. This September 1 rollout is a different, separate migration track for standard Search campaigns and is not being delayed. Advertisers who assumed all AI Max transitions were postponed are the ones most likely to be caught unprepared.
The DSA migration timeline change to February 2027 is worth reviewing alongside this article, since both changes affect how much manual control advertisers retain over ad delivery through the rest of 2026 and into 2027.
What Search Term Matching and Text Customization Mean in Practice
Search term matching allows Google's models to decide which search queries your ads are eligible for, going beyond the literal match type rules attached to your keyword list. Text customization allows Google to generate and serve headline and description variations automatically, adjusted to the specific query.
Both mechanisms trade precision for reach. Google's stated internal data claims campaigns running the full AI Max feature combination - search term matching, text customization, and final URL expansion - see roughly 7% higher conversions or conversion value at a comparable CPA or ROAS than campaigns using search term matching by itself. That figure specifically excludes retail advertisers and reflects Google's own 2026 measurement, not an independent benchmark.
A Practical Pre-Migration Checklist
- Open every active Search campaign and check whether Automatically Created Assets or campaign-level broad match is turned on.
- For campaigns where either is enabled, decide now whether you want the September 1 upgrade to proceed or whether you want to disable the setting beforehand to opt the campaign out.
- Audit your negative keyword lists and brand exclusion settings before the upgrade, not after - broader search term matching without solid negative coverage is the single most common cause of wasted spend following an AI Max conversion. The AI Max negative keywords and brand exclusions guide walks through this setup.
- Flag campaigns in regulated categories or with strict brand-language requirements for manual review after the switch, since AI-generated text variations may not match approved messaging.
What Changes for Advertisers Who Do Nothing
If you take no action, any qualifying campaign converts automatically on Google's timeline, and the new settings apply without a review step on your side. Google frames this as a low-friction improvement, but "low-friction" from the platform's perspective can mean higher spend variance from the advertiser's perspective, particularly in the first weeks after conversion while search term matching expands your effective reach.
The safest posture for most accounts is not blanket opt-out, but selective review - identify which campaigns matter most for cost control or brand precision, and treat those differently from campaigns where broader automated reach is genuinely welcome.
The Broader Pattern Behind This Rollout
This September 1 change is not an isolated event. Google converted Shopping campaigns toward AI Max earlier in 2026, announced the DSA migration and then delayed it to February 2027 after advertiser pushback, and is now moving standard Search campaigns with Automatically Created Assets or broad match onto the same framework. Each step narrows the gap between manually configured campaigns and Google's AI-managed default.
For account planning purposes, treat this as a trend rather than a one-time adjustment. Advertisers who build a recurring quarterly habit of reviewing which campaigns run on which automation settings will handle the next mandatory conversion with far less disruption than advertisers who only look at these settings when Google forces the issue through an email notice.
FAQ
Which campaigns are affected by the September 1 AI Max upgrade?
Only Search campaigns currently using Automatically Created Assets or the campaign-level broad match setting. Campaigns without either setting active are not part of this migration.
Is this connected to the Dynamic Search Ads to AI Max change?
No, they are separate migrations on separate timelines. The DSA migration was delayed to February 2027. This September 1 upgrade for standard Search campaigns is proceeding as originally announced.
What is the fastest way to check if my account is affected?
Open campaign settings for each active Search campaign and look for Automatically Created Assets and campaign-level broad match. If either shows as enabled, that campaign is in scope for the automatic conversion.
Should every advertiser disable these settings before September 1?
Not necessarily. Advertisers comfortable with broader automated reach and Google's AI-generated text variations can let the upgrade proceed. Advertisers with strict brand-language or compliance requirements should review and likely disable the settings before the deadline.
