Google Ads AI Max Malaysia: What Every Advertiser Must Do Before the September Migration Hits

If you’re running Google Ads in Malaysia and your campaigns use Dynamic Search Ads, automatically created assets, or campaign-level broad match, Google has already started rewriting them. The rollout is called Google Ads AI Max for Search — and unlike most Google updates, there is no opt-out. The automatic migration of affected campaigns began September 1, 2026, and it will proceed whether you’re ready or not.

This article explains exactly what AI Max changes, what risks Malaysian advertisers need to manage immediately, and the step-by-step checklist to run before Google applies its own default settings to your account. If you want the foundational background on what AI Max is, our earlier breakdown of Google Ads AI Max covers the feature set in detail. This article is about what’s happening to your account right now — and what to do about it.

What Is Google Ads AI Max for Search — and Why It Replaces DSA, ACA, and Broad Match

Google Ads AI Max for Search is a unified campaign intelligence system that consolidates three legacy features into a single AI-driven framework. Specifically, it replaces Dynamic Search Ads (DSA), which automatically generated headlines and picked landing pages from your website; Automatically Created Assets (ACA), which generated additional headlines and descriptions beyond your manually written copy; and campaign-level broad match, which matched your ads to searches far beyond your exact keyword list.

For the past three years, Google’s account management teams actively recommended all of these features to Malaysian advertisers — often without explaining the underlying mechanics. Now that they’re being consolidated into AI Max, the combined effect gives Google’s algorithms significantly more control over who sees your ads, what your ads say, and where your clicks land. Understanding the risk profile of each component is the starting point for managing this transition without losing campaign performance.

The Migration Timeline Every Malaysian Advertiser Needs to Know Right Now

The migration is already underway. Here is the confirmed schedule from Google’s official developer documentation and email notifications sent to advertisers:

August 3, 2026: Google blocked creation of new campaign-level broad match settings and legacy ACA configurations in the Ads UI, Ads Editor, and API
August 5, 2026: Email notifications sent to all affected advertisers
September 1–30, 2026: Automatic migration of existing ACA and broad-match Search campaigns begins, campaign by campaign, without requiring advertiser confirmation
February 1–28, 2027: DSA campaigns migrate automatically (deadline extended from September 2026 after widespread advertiser feedback about Q4 timing risk)

As Tarun Karan of Turaingrp.com summarises the situation: “You’re not choosing whether to keep the old setup. That choice is already gone. What you’re choosing is whether to configure the migration yourself, or let Google do it for you with default settings.”

For Malaysian advertisers, the practical consequence is immediate. If your Search campaigns use any of the three affected features, your account is in the migration queue. The only remaining variable is whether you define the boundaries AI Max operates within before Google applies its own defaults.

What Google’s AI Will Actually Change About Your Campaigns

Google Ads AI Max has three components. Each carries a different risk level, and understanding the distinction matters — especially for Malaysian advertisers in regulated sectors or those relying on WhatsApp as a primary conversion channel.

Search Term Matching: The Expanded Query Window

AI Max replaces campaign-level broad match with “search term matching” — a keywordless system where Google’s AI determines which queries your ads are eligible to serve. For advertisers already running broad match, this is largely the same behaviour with enhanced signals. AI Max’s matching draws on your landing page content, ad assets, and real-time query context to decide which searches trigger your ads.

The upside is documented. Jonathan Tablada, HubSpot’s lead paid ads marketer, ran 40-plus campaign trials using Google Ads Experiments with proper 50/50 cookie-based splits — and found a 12% increase in conversions. However, he’s direct about the conditions required: “It’s definitely not autopilot. The broader you get, the more you want to keep a close eye on your search term report. Otherwise, you could be spending on areas that are very inefficient.”

Final URL Expansion: The Most Dangerous Feature in Google Ads AI Max Malaysia

Final URL expansion allows Google’s AI to override the landing page URL you set for an ad — routing the user to whichever page on your domain its algorithm judges most relevant to the specific query. The system simultaneously rewrites the ad headline to match that page. This feature does not activate automatically for broad-match campaigns, but it does activate by default for Automatically Created Assets campaigns when text customization becomes live post-migration. Verify your settings immediately if your campaigns used ACA.

The risk is severe and documented. Yulian Hrab, a PPC agency owner who tested AI Max on live client accounts, found Google routing paid traffic directly to his client’s thank-you confirmation page — the page that loads after a lead submits a form. Because his conversion tracking fired on page load, every click registered as a completed conversion. The campaign appeared to perform well for weeks before the problem was discovered via a landing page report. The account was manufacturing its own results.

“Turn final URL expansion off. In a second account it sent paid traffic directly to our thank you page, which registered as a conversion every time. URL exclusions did not prevent it. Only URL inclusions — a whitelist of specifically permitted pages — provide a reliable fence.” — Yulian Hrab, Excellappc.com

For Malaysian businesses, this issue has an additional dimension. Conversion tracking in Malaysia commonly includes WhatsApp link clicks as a primary lead event. Confirm that your WhatsApp click tracking cannot be triggered by an AI-routed page visit before your migration proceeds.

Text Customization: Google Rewrites Your Ad Copy

Text customization enables Google to generate new headlines and descriptions beyond your manually written ad copy, drawing from your existing ads, landing pages, and search context. For ACA campaigns, this feature activates by default after migration. For Malaysian advertisers in regulated sectors — healthcare, financial services, property development — this carries real compliance risk. Bank Negara guidelines, Securities Commission rules, and the Malaysian Medical Council’s advertising standards all restrict the claims advertisers can make. An AI-generated headline claiming “guaranteed returns” or “fastest approval” could trigger regulatory problems. Text guidelines exist specifically to prevent this, but they must be configured before migration occurs.

The Controls You Still Have — and How to Set Them Before Google Applies Its Defaults

Despite the mandatory nature of the migration, Google does preserve meaningful advertiser controls. Access them through the voluntary upgrade prompt in the Google Ads UI — navigate to Campaigns, select an affected campaign, go to Settings, and look for the AI Max upgrade banner. Using this prompt before your campaign’s migration turn gives you hands-on control of the settings. Waiting means inheriting Google’s defaults.

Brand Controls

Brand inclusions list your own brand terms so the AI associates them positively. Brand exclusions list competitor brands or unrelated brand names you want your ads excluded from. Without brand exclusions, AI Max will freely match to competitor queries. If you already have brand lists in your account, they carry over automatically — but verify they are current before migration.

Text Guidelines

Google gives you two layers of text customisation control. Term exclusions are specific words or phrases (up to 30 characters each, maximum 25 per campaign) that cannot appear in AI-generated copy — use these for words like “free,” “cheap,” competitor names, or any legally regulated terms relevant to your sector. Messaging restrictions are freeform instructions (up to 40, each up to 300 characters) guiding the AI’s tone and content — use these for required disclosures, regulatory language, and brand voice rules.

For Malaysian advertisers running multilingual campaigns in both Bahasa Malaysia and English — which is standard practice in the JB-Singapore corridor — messaging restrictions should explicitly specify language usage rules. Without them, AI Max may generate mixed-language copy that doesn’t match your intended brand voice.

Location Controls

Set location-of-interest targeting at the ad group level to prevent AI Max’s expanded query matching from drawing in searches from outside your intended service area. This matters for Malaysian businesses with state-specific licences, franchise territory restrictions, or service areas bounded by logistics constraints.

What the Performance Data Actually Shows

Google claims AI Max delivers 7% more conversions or conversion value at similar CPA/ROAS. Read the fine print carefully. That figure compares the full AI Max suite against campaigns running only AI Max’s search term matching feature — not against your current baseline setup. As Hrab puts it: “Nobody’s baseline is ‘AI Max with two features disabled.'”

However, independent testing data shows genuinely mixed results depending on account type. HubSpot’s 40-plus campaign trials found a 12% conversion lift — but HubSpot operates a large, high-volume account with mature conversion data, purpose-built landing pages, and an active team managing negative keywords. Hrab’s agency tests on smaller SMB client accounts found ROAS dropped 46.1% while spend rose 145.5% over the same test period.

The pattern matches what Google’s own internal data actually says: accounts with the tightest existing targeting — lots of exact and phrase match, clean conversion signals, and well-maintained landing pages — have the most to gain from AI Max’s expanded query matching. Accounts already running broad match everywhere, or accounts with loose conversion tracking, have the least room for improvement.

Malaysian SMBs who accepted Google’s broad-match recommendations over the past few years should approach AI Max with preparation rather than expectation. For help auditing your conversion tracking setup before migration, review your account’s current signal quality first.

Your Google Ads AI Max Pre-Migration Checklist for Malaysian Advertisers

Run these steps before your campaign’s migration turn. If you need hands-on support with your Google Ads management, a migration audit now is significantly cheaper than recovering lost ROAS after the fact.

Identify affected campaigns. Filter for Search campaigns using campaign-level broad match or ACA. Standard keyword-based campaigns without these settings are not migrating in September.
Use the voluntary upgrade prompt. Find the AI Max upgrade banner in your campaign settings and initiate migration manually — this gives you control over defaults instead of inheriting Google’s.
Set brand exclusions. List every competitor brand and unrelated brand name you want excluded from AI Max’s query matching.
Set term exclusions. List regulated terms, competitor names, and any words that should never appear in AI-generated copy for your business.
Write messaging restrictions. Add guidelines covering brand voice, required disclosures, language restrictions (BM/English), and industry regulatory constraints.
Configure location controls. Set service area boundaries at the ad group level to prevent geographic overreach.
Decide on final URL expansion. If you enable it, use URL inclusions (a whitelist of permitted pages) rather than URL exclusions. If you’re unsure, leave it off entirely until you’ve tested other AI Max features first.
Audit your conversion tracking. Confirm that conversion events — especially WhatsApp click tracking — are firing correctly before AI Max expands your query volume.
Pull a search terms baseline. Export a full search terms report now. You need a before-state to compare against once AI Max begins matching to new queries.
Refresh your landing pages. Text customisation draws from your existing page copy. Outdated or legally imprecise content becomes a liability when Google generates ad variants from it.

If you want to understand how AI Max sits within the broader shift in AI marketing tools for Malaysian businesses, that context is worth reviewing alongside your migration planning.

Frequently Asked Questions: Google Ads AI Max Migration Malaysia

What is Google Ads AI Max for Search?

Google Ads AI Max for Search is Google’s unified search campaign intelligence system that consolidates Dynamic Search Ads, Automatically Created Assets, and campaign-level broad match into a single AI-powered framework. It controls search term matching, ad copy generation, and — optionally — landing page selection via final URL expansion.

Which campaigns are being migrated in September 2026?

Search campaigns using campaign-level broad match or Automatically Created Assets are migrating between September 1 and September 30, 2026. DSA campaigns are on a separate timeline — automatic migration begins February 1, 2027.

Can I opt out of the Google Ads AI Max migration?

No. The migration is mandatory. There is no opt-out path. The only decision remaining is whether to configure the brand controls, text guidelines, and location controls yourself before your campaign’s migration turn — or let Google apply its own default settings.

What is final URL expansion and should I enable it?

Final URL expansion lets Google’s AI override your ad’s landing page URL and route clicks to whichever page on your site it judges most relevant. In documented agency tests, this has sent paid clicks to post-conversion thank-you pages, generating phantom conversions. If you enable it, use URL inclusions (a whitelist) rather than URL exclusions. Most advertisers, especially those with looser landing page structures, should leave it off during initial migration.

How does the Google Ads AI Max migration affect Malaysian advertisers specifically?

Malaysian advertisers face several unique risks: WhatsApp click tracking may conflict with AI Max’s expanded URL behaviour; regulated sectors including healthcare, finance, and property need text guidelines to prevent non-compliant AI-generated copy; and multilingual campaigns in Bahasa Malaysia and English need language restrictions in messaging guidelines to prevent unexpected code-switching. Configure all three controls before your campaigns migrate.
