AI Max for Search is not a new campaign type, and in many Google Ads accounts nobody on the team turned it on. Google said Search campaigns using automatically created assets or the campaign-level broad match setting would be upgraded to AI Max starting in September 2026, and new Search campaigns have it on by default. It is a layer of automation inside your existing campaigns that widens which searches trigger your ads, writes ad text from your landing pages, and can send clicks to pages you didn’t pick. This guide shows what it changes, how to see what is active, and what to check before you let it keep spending.
Key Takeaways
- It’s a layer, not a campaign type. Google’s help center describes AI Max for Search as an optimization layer inside Search campaigns, built on search term matching and asset optimization.
- Check whether it’s already on. Google began auto-upgrading campaigns that used automatically created assets or the campaign-level broad match setting in September 2026. Dynamic Search Ads start moving in February 2027.
- It needs trustworthy conversion data. Google’s setup page says search term matching, Final URL expansion, and text customization require conversion-based Smart Bidding to work effectively.
- It reads your website. Text customization and Final URL expansion draw on your landing pages, so outdated pages can turn into outdated ads and destinations.
- Controls exist. Text guidelines (beta), URL exclusions, brand settings, locations of interest, and built-in experiments let you steer and test it.
- Google’s 7% figure is Google’s. Its internal 2026 data shows 7% more conversions or conversion value at a similar CPA or ROAS for the full feature suite versus search term matching alone. Treat it as a hypothesis to test, not a promise.
What is AI Max for Search, and is it a new campaign type?
No. Google’s help center says AI Max for Search is not a new campaign type but an optimization layer within existing Search campaigns. It adds automation in two places. Search term matching uses broad match and keywordless technology to show your ads on searches your keywords don’t literally cover. Asset optimization has two parts: text customization, which writes ad copy from your existing ads, landing page copy, and assets using generative AI, and Final URL expansion, which can send clicks to the page on your site most likely to perform. Turning AI Max on switches on search term matching, text customization, and Final URL expansion together, though you can toggle them individually.
It is also different from Performance Max, which Google treats as a separate product. AI Max keeps your familiar Search campaign structure.
| Feature | What it does | Where you control it |
|---|---|---|
| Search term matching | Reaches related searches using broad match and keywordless technology | Ad group level, once the campaign has it on |
| Text customization | Uses generative AI to write ad text from your ads, landing pages, and assets | Campaign level, plus text guidelines (beta) |
| Final URL expansion | Sends traffic to the most relevant URL on your domain. Requires text customization. | Campaign level, with URL exclusions |
| Brand settings | Limits which brands your ads appear with, or alongside | Exclusions at campaign level, inclusions at campaign or ad group level |
| Locations of interest | Reaches people based on geographic intent, even in keywordless matches | Ad group level |
What are the most common myths about AI Max for Search?
Four misunderstandings cause most of the trouble, and Google’s own documentation answers each one. The first is that AI Max is a campaign you can ignore if you never created it. It is a layer inside existing campaigns, and legacy settings were upgraded into it. The second is that you can’t see what it’s doing. Google says the search terms report adds an AI Max match type and a source column, and the asset report shows how generated assets perform. Google also says you can remove generated assets and use URL controls to decide where customers land. The third is that it replaces your keywords.
Google says search term matching expands on your existing keywords and learns from your keywords, creatives, and URLs, so your setup still shapes what it does. The fourth is that more automation always means better results.Google’s 7% figure compares the full feature suite with search term matching alone, as an average across advertisers, and Google says it can’t guarantee a specific ROI from text guidelines. Your account may land above or below that average, which is why testing matters.
Did Google already turn on AI Max for Search in your account?
Possibly. In an April 2026 announcement, Google said that starting in September, campaigns using automatically created assets, the campaign-level broad match setting, and Dynamic Search Ads would be upgraded to AI Max, and it expected the eligible upgrades to conclude by the end of September. A June 11 update on Google’s Ads blog pushed the Dynamic Search Ads timeline back so it begins in February 2027, while automatically created assets and broad match campaigns kept the September schedule.
New Search campaigns also have AI Max on by default, according to Google’s setup guide. So an account can be running AI features nobody chose. You can see AI Max settings in each campaign’s settings, and Google says they can be added as columns in the campaign list view.
Picture a Connecticut HVAC company that switched on automatically created assets two years ago to save time writing ads. After the September upgrade, that campaign runs AI Max with search term matching and text customization on. Nobody touched it, but it now matches more searches and shows AI-written text.
| Legacy setting | What Google said it becomes | Timing |
|---|---|---|
| Automatically created assets | AI Max with search term matching and text customization on | Auto-upgrade began September 2026 |
| Campaign-level broad match setting | AI Max with search term matching on | Auto-upgrade began September 2026 |
| Dynamic Search Ads | AI Max with all three features on and legacy URL controls preserved | Auto-upgrade begins February 2027 |
What should you check before leaving AI Max for Search on?
Check five things: your conversion data, your budget, your landing pages, your tracking templates, and your brand and location controls. AI Max optimizes toward the signals you give it, so weak inputs produce confident-looking waste. Most of these checks take minutes, and several come straight from Google’s own documentation. Work through them in order, because a problem in an earlier step can distort everything after it.
- Confirm conversion tracking and bidding. Google’s setup page says search term matching, Final URL expansion, and text customization require conversion-based Smart Bidding strategies to function effectively. That only helps if the conversions are real. Count each lead once, separate real calls from accidental taps, and confirm forms fire on submission. Lorphic’s guide to knowing whether your digital marketing is working covers how to sanity-check the numbers.
- Look for budget limits. Google notes that AI Max won’t be effective if a campaign is limited by budget, and shows an alert when that happens. A campaign that runs out of money by mid-afternoon can’t use wider matching well.
- Review the pages Google can use. Text customization uses landing page copy, and Final URL expansion can pick other URLs on your domain. Outdated service pages, old promotions, and thin pages are all candidates. Google says URL exclusions need text customization and Final URL expansion turned on, and that “URL contains” rules match exact words, not partial strings.
- Test your tracking templates. Google warns that dynamic landing pages can lead to 404 errors if a tracking template isn’t compatible. A template with a static URL and no {lpurl} tag can send users to that static page instead of the dynamic one. Verify a dynamic landing page works before turning AI Max on.
- Set brand and location controls. Add brand exclusions where needed, and review locations of interest if your service area is narrow.
How do you keep AI-written ads in bounds?
Use text guidelines, URL exclusions, and a regular review of the assets Google generates. Text guidelines are a beta feature that works only when text customization is on. They have two parts: term exclusions, up to 25 per campaign, and messaging restrictions, up to 40. Google says guidelines also apply to existing generated assets, which stop serving and are marked as removed if they don’t comply. Term exclusions are language-specific and can’t block price assets, so Google suggests a restriction like “don’t generate assets with prices” instead.
Messaging restrictions work best when they are clear and direct, and Google says vague ones, such as “my ads should bring joy,” don’t work. Google’s own page also says it can’t guarantee a specific ROI from text guidelines.
For Connecticut advertisers in legal, financial, or healthcare services, the rules about claims still apply to every line of generated text. The FTC’s advertising guide for small businesses says advertising must be truthful and that advertisers need evidence for their claims, and your regulator may add its own rules. Treat the generated assets as copy that needs approval, not as a feature you can set and forget.
| Guardrail | What Google says it does | Use it for |
|---|---|---|
| Term exclusions | Blocks exact words or phrases from generated text | Words you never want in ads |
| Messaging restrictions | Sets concepts and tone to avoid or follow | Claims, tone, and how you describe offers |
| URL exclusions | Keeps pages from serving as landing pages | Pages that should never get paid traffic |
| Brand exclusions | Prevents your ads from appearing with specific brands | Competitor or unrelated brand traffic |
A few restrictions to adapt, which are our suggestions and not Google’s examples. Test them by reviewing the generated assets afterward:
- Do not state or imply guaranteed results.
- Do not mention specific prices.
- Do not describe our services as the cheapest.
How do you test AI Max for Search without risking your budget?
Run an AI Max experiment. Google’s experiments guide says these tests divert traffic and budget inside your existing campaign instead of copying it. The control arm runs with AI Max off, and the trial arm runs with it on. By default the trial turns on all three features, but you can deselect text customization or Final URL expansion for the trial. When the test ends you can apply it, or end it without applying and everything reverts. Brand settings you add during setup apply to both arms.
Some campaigns can’t use this flow. Google lists these exclusions:
- Campaigns with text customization (formerly automatically created assets) already enabled
- Campaigns targeting the Display network
- Campaigns in a portfolio bidding strategy
- Campaigns using shared budgets or bidding exploration
- Campaigns with another active experiment
If your campaign fits that list, Google says custom experiments are still available, which copy the campaign into a separate control and trial. Whichever route you use, decide before you start what success means. Judge the test by cost per qualified lead or booked job, not by clicks, since AI Max can raise traffic without raising results.
How do you read the results once AI Max for Search is running?
Read the new columns in the search terms report first, then the landing pages and asset reports. Google says the search terms report includes AI Max as a new match type for incremental search terms, plus a source column showing whether a match came from broad match expansion or keywordless matching. It also adds a view combining the search term, headline, and URL, so you can see what a searcher saw. The landing pages report has a “Selected by” column, and the asset report shows how AI Max assets are performing.
| Report | What AI Max adds | What to look for |
|---|---|---|
| Search terms | An “AI Max” match type and a source column | Searches that don’t match what you sell |
| Search terms, combined view | The search term with headlines and URLs | Headlines or pages that don’t fit the query |
| Landing pages | A “Selected by” column | Pages Google chose that you’d have excluded |
| Assets | Performance of generated assets | Text that overstates, misstates, or breaks your guidelines |
What changes for Dynamic Search Ads?
Dynamic Search Ads campaigns move to AI Max, with the automatic upgrade starting in February 2027. Google offers upgrade tools now, so you can choose the timing and keep control. Per Google’s setup page, the upgrade converts dynamic ad groups into standard ad groups and turns existing Dynamic Search Ads into Responsive Search Ads, with Google generating the minimum static assets through text customization. Your legacy Dynamic Search Ads keep running temporarily while the new ads are generated and checked for policy compliance, and they are paused and set to view-only once the new ads are active. Legacy URL rules such as “page title contains” become read-only. You can remove them, but you can’t add or edit them.
If you run Dynamic Search Ads, use the lead time. Review which pages the campaign currently targets, decide which URL controls you want to keep, and upgrade on your own schedule before Google does it for you.
Decision framework: should you leave AI Max for Search on?
Match your situation to the first move below. These are judgment calls built on Google’s documentation, not Google recommendations. Google itself suggests turning on all AI Max features and testing with experiments, so use these rows to decide what to fix before you do that.
| Your situation | Do this first | Why |
|---|---|---|
| Conversion tracking is unverified | Fix tracking before anything else | Google says the features need conversion-based Smart Bidding to work effectively |
| The campaign runs out of budget daily | Fix the budget or narrow the campaign | Google says AI Max won’t be effective when budget-limited |
| Landing pages are thin or out of date | Update them, or add URL exclusions | Text customization and Final URL expansion draw on your pages |
| You advertise legal, financial, or health services | Add text guidelines and review generated assets before scaling | You remain responsible for every claim in your ads |
| You use shared budgets or portfolio bidding | Use a custom experiment | The one-click experiment flow doesn’t support those setups |
| You still run Dynamic Search Ads | Upgrade on your own schedule before February 2027 | Google’s upgrade tools port over historical settings and data, and upgrading early keeps you in control |
Three questions settle most decisions:
- Can you trust your conversion data?
- Would you be comfortable with any of your site’s pages showing up as an ad destination?
- Who reviews the generated text before it causes a problem?

Frequently Asked Questions
Is AI Max the same as Performance Max?
No. Google says AI Max is a suite of features that optimizes Search campaigns and lets advertisers keep familiar Search structures, while Performance Max is a separate campaign product. AI Max is not a new campaign type. It is an optimization layer you turn on inside an existing Search campaign.
Did Google turn on AI Max in my account without asking?
Possibly. Google said that starting in September 2026, campaigns using automatically created assets or the campaign-level broad match setting would be upgraded automatically, and that new Search campaigns have AI Max on by default. Check each Search campaign’s settings for the AI Max section to see which features are active.
Can I turn AI Max off?
Google’s setup page explains how to opt out of AI Max settings at the campaign level and how to adjust search term matching by ad group. It also notes that turning off text customization removes the generated assets and that Final URL expansion stops working without it. Google also notes that re-enabling AI Max restores the same features as previously set, so review each setting before you change it.
Does AI Max write my ads?
Text customization does, using generative AI with your existing ads, landing page copy, and assets as source material. You can limit the output with text guidelines, review generated assets in reporting, and turn text customization off. If you do, Google says Final URL expansion is disabled as well.
Does AI Max for Search work for small budgets?
Google doesn’t set a minimum on the pages we reviewed, but it does say AI Max won’t be effective when a campaign is limited by budget. Fix budget limits and conversion tracking first, then test it with an experiment before applying it to the whole campaign.
How should I test AI Max?
Use an AI Max experiment, which splits traffic and budget inside the campaign, with AI Max off for the control and on for the trial. Decide your success metric in advance, such as cost per qualified lead, and apply the change only if results hold up. If the experiment ends without being applied, settings revert.
