Google AI Max for Search is a suite of AI-powered targeting and creative features inside a Google Ads Search campaign. It expands your reach beyond exact keywords with broad match and keywordless matching, auto-generates ad text from your pages, and routes clicks to your most relevant URLs. It is a feature layer you switch on, not a new campaign type, and it is set to replace Dynamic Search Ads for all advertisers by the end of September 2026.
- What it is: a toggle-on feature layer for existing Search campaigns (not a campaign type, not a bid strategy, not Google's consumer AI search)
- Core features: search term matching, text customization, final URL expansion, plus brand and URL controls
- Performance: Google reports about 7% more conversions on average at a similar CPA or ROAS (up to 14% at launch in 2025)
- The 2026 deadline: Dynamic Search Ads auto-upgrade to AI Max starting September 2026
- The catch: advertisers report cost-per-click up 10 to 25% and rising budgets, so the controls matter
What is Google AI Max for Search?
Google AI Max for Search is, in Google's words, “a comprehensive suite of targeting and creative enhancements that brings the best of Google AI to your Search campaigns.” In plain terms, it is a set of features you switch on inside a Search campaign to let Google's AI find more relevant queries and write more relevant ads than your keyword list can on its own. It launched in beta in May 2025 and rolled out to advertisers globally over the following year.
The single most important thing to understand is what AI Max is not. The name causes real confusion, so here is the disambiguation up front:
- It is not a new campaign type. It is a feature layer inside the Search campaigns you already run. You enable it in settings.
- It is not a bid strategy. It works alongside Smart Bidding, but AI Max governs targeting and creative, not how bids are set.
- It is not Google AI Overviews or Google AI Mode. Those are consumer search experiences that answer queries on the results page. AI Max is a paid advertising feature. They share the AI label and nothing else.
- It is not Performance Max. Performance Max is a separate, fully automated cross-channel campaign type. AI Max stays inside Search and keeps your controls.
That confusion is not just a reader problem. Ask an AI assistant “what is Google AI Max” and several will conflate it with consumer AI search features or automated bidding. The accurate definition is narrow: a Search-campaign feature layer for advertisers, built on broad match and keywordless matching.
AI Max is a feature you switch on inside a Search campaign. It is not a new campaign type, and it is not Google's consumer AI search.
How does AI Max work?
AI Max works through two pillars: search term matching and asset optimization. Search term matching uses broad match and keywordless technology to find queries your exact and phrase keywords would miss. Asset optimization uses Google AI to generate and tailor your headlines, descriptions, and landing-page routing in real time. A set of controls sits on top so you can keep both pillars inside the lines.
The feature most B2B advertisers should watch is final URL expansion. It lets Google send a click to whichever page on your site it predicts will convert best, rather than the single final URL you set. Useful when your site is deep and well-structured, risky when it is not, which is exactly why the URL inclusion and exclusion controls exist. Google documents all of these in its AI Max help article, including a search terms report that labels each query by how AI Max matched it.
For visibility, the AI Max match type appears in your search terms report with a source column showing whether a query came from broad match or keywordless expansion. That report is where you will spend most of your management time, because it is how you catch irrelevant matches early. This is the same keywords-to-intent shift playing out in Google's organic surfaces, which we cover in Google AI Mode ad formats.
AI Max vs Dynamic Search Ads vs Performance Max
These three get mixed up constantly because all three reduce the manual keyword work. They are different tools for different jobs. Dynamic Search Ads is the legacy automation being retired. Performance Max is full cross-channel automation with little transparency. AI Max is the Search-only middle ground: more automation than a manual keyword campaign, more control than Performance Max.
The practical read for most Search advertisers: AI Max is the natural home if you want AI to extend your reach but you still need keyword-level reporting and the ability to steer it. If you have already gone all-in on cross-channel automation, you are likely running Performance Max alongside it, not instead of it. Teams using ChatGPT as a Google Ads copilot often use AI Max's search terms report as the weekly input for mining negatives and spotting wasted spend.
Google is replacing Dynamic Search Ads with AI Max in 2026
This is the part that makes AI Max urgent rather than optional. In April 2026, Google confirmed that Dynamic Search Ads are being upgraded to AI Max and called AI Max “the next generation of Dynamic Search Ads.” Dynamic Search Ads will be deprecated as a standalone product. If you run them, you are moving to AI Max regardless of whether you choose to.
The timeline matters. Voluntary upgrade tools opened in April 2026, which is the window to move on your own terms and learn the new controls before they apply by default. Starting in September 2026, Google begins upgrading remaining eligible campaigns automatically, and you can no longer create new Dynamic Search Ads. By the end of September 2026, the migration is expected to be complete. Google's own framing is a “strategic shift from manual maintenance to scalable, AI-powered growth,” which is the polite version of: the manual era of Search automation is ending. The full announcement is on the Google Ads blog.
If you run Dynamic Search Ads, the upgrade is not optional. The only choice is whether you do it on your terms before September 2026 or let Google do it for you.
How to turn on AI Max
Enabling AI Max takes a few minutes, but doing it well means turning on the controls in the same sitting. Here is the sequence.
- Open an existing Search campaign's settings. AI Max is enabled per campaign, so start with one campaign rather than the whole account.
- Switch on the AI Max feature set. This turns on search term matching and the option for text customization and final URL expansion.
- Set your brand controls. Add brand inclusions and exclusions so your ads associate with, or avoid, the brands you specify before any spend runs.
- Set your URL controls. Add URL exclusions for any page you never want serving as a landing page, and URL inclusions for pages final URL expansion might otherwise miss.
- Launch, then check the search terms report after a few days. Filter to the AI Max match type, review what the keywordless expansion surfaced, and add negatives for anything off-target.
Step 5 is the one teams skip and regret. Keywordless matching is designed to be expansive, so the first week is where you teach it your boundaries. Treat the first 30 days as calibration, not steady state.
AI Max one year on: the performance reality
Google's headline number is that AI Max delivers about 7% more conversions or conversion value at a similar CPA or ROAS. At launch in May 2025, Google reported a larger figure, up to 14%, and 27% for campaigns that relied mostly on exact and phrase keywords. Its case studies are strong: L'Oréal cited a 2X higher conversion rate at a 31% lower cost per conversion, and MyConnect reported 16% more leads at a 13% lower cost per action.
One year on, the independent picture is more mixed, and it is worth seeing both sides at once.
As Digiday reported in May 2026, agencies welcomed AI Max's creative features and its reach into long-tail, conversational queries, but flagged a cost story underneath the conversion story. Cost-per-click rose 10 to 15 percent on average, and up to 25 percent for some accounts. Search budgets grew 7 to 15 percent year on year, and the number of advertisers in the search auction climbed 35 percent. “The CPC pain is real,” Adthena's chief marketing officer told the publication.
Both things are true. AI Max can find conversions your keyword campaigns missed, and it can raise what you pay to win them, because keywordless expansion puts you into more auctions against more bidders. For a B2B advertiser, that makes the quality of the added conversions the whole ballgame.
A 7% lift in conversions means little if your cost per qualified lead climbs faster. In B2B, the added conversions are only worth the added spend if they are the right conversions.
AI Max guardrails for B2B advertisers
AI Max is tuned to maximize conversions, and in B2B a conversion is not the same as a qualified lead. A wrong-fit click is expensive, a junk form-fill pollutes your pipeline data, and keywordless expansion can wander into adjacent intent fast. Five guardrails keep AI Max working for a B2B funnel rather than against it.
1. Turn on brand controls before you spend
Set brand exclusions so your ads do not surface alongside competitors or off-brand contexts, and brand inclusions where association helps. This is the cheapest insurance against AI Max putting your budget somewhere your brand should not be.
2. Use URL controls to protect final URL expansion
Final URL expansion will route clicks to the page it predicts converts best. Exclude thin pages, gated content, and anything not built to convert paid traffic, and include the deep pages it might overlook. Pair this with a conversational landing page for the queries that matter most.
3. Read the search terms report weekly
The AI Max match-type column is your early-warning system. Keywordless expansion is where wasted spend hides, so review it weekly and add negatives aggressively in the first month. This is non-negotiable for B2B, where one irrelevant high-cost vertical can drain a test budget.
4. Keep a tight negative keyword list
Broad match plus keywordless matching widens reach by design, so your negative list does more work than it did under exact match. Translate your existing negatives, then add the B2B usual suspects: job seekers, students, free-tool hunters, and do-it-yourself researchers who will never buy.
5. Judge AI Max on qualified pipeline, not conversion volume
Tie AI Max conversions back to your CRM and measure cost per qualified lead and closed pipeline, not raw conversions. A 7% conversion lift that arrives with a lower lead-quality score is a loss dressed as a win. Lead quality is the metric the headline numbers never show.
What AI Max means for AI-era marketing
Step back from the campaign settings and AI Max tells a bigger story. Google is moving paid search away from the exact keywords a person types and toward the intent behind them. Keywordless matching is Google conceding that the keyword, the unit search was built on for two decades, no longer captures how people express what they want.
The same shift is reshaping organic discovery. Buyers increasingly ask an AI assistant for a recommendation instead of typing keywords into a search box, and the assistant answers from whatever it has been trained on and can retrieve. That is the world answer engine optimization exists for, and it is why paid and organic AI visibility increasingly move together.
The two connect at the bottom line. Brands that already appear in AI answers convert their paid clicks at higher rates, because buyers arrive warm rather than cold. That compounding effect, the AI Visibility Lift, means an AI Max campaign running on top of strong organic citations works harder than one running cold. If AI Max is your signal that keyword-era tactics are fading, the response is to make sure AI assistants can find and cite you in the first place.

#Is Google AI Max a new campaign type?
No. AI Max for Search is a feature layer you switch on inside an existing Google Ads Search campaign, not a separate campaign type. You enable it from your campaign settings, and it adds AI-powered search term matching and creative generation on top of the keywords and structure you already have. You can also turn the individual features off.
#Is AI Max the same as Google AI Overviews or AI Mode?
No, and this is the most common confusion. AI Max for Search is a paid Google Ads feature for advertisers. Google AI Overviews and AI Mode are consumer search experiences that summarize and answer queries on the results page. They are unrelated products that happen to share the AI label. AI Max decides how your ads compete; AI Overviews and AI Mode decide how organic answers are shown.
#Is AI Max replacing Dynamic Search Ads?
Yes. Google has called AI Max the next generation of Dynamic Search Ads. Voluntary upgrade tools opened in April 2026, and starting in September 2026 eligible legacy campaigns upgrade automatically while new Dynamic Search Ads creation ends. If you run Dynamic Search Ads, you will move to AI Max either on your own schedule or automatically by the end of September 2026.
#How is AI Max different from Performance Max?
AI Max stays inside the Search network and keeps keyword-level visibility and controls. Performance Max is a separate, fully automated campaign type that spans Search, Display, YouTube, Gmail, Discover, and Maps with far less transparency. Think of AI Max as more automation with the controls intact, and Performance Max as maximum automation across every channel.
#Does AI Max increase cost-per-click?
It can. One year after launch, agencies reported cost-per-click rising 10 to 25 percent and search budgets growing 7 to 15 percent year on year, partly because AI Max opens up query space advertisers were not previously bidding on. Google reports about 7 percent more conversions at a similar CPA or ROAS, so the lever is whether the added conversions are worth the added spend for your funnel.
#Can I control where AI Max sends traffic and which brands it appears next to?
Yes. Brand controls let you set brand inclusions and exclusions so your ads associate with, or avoid, specific brands. URL inclusions and exclusions govern final URL expansion so it cannot route clicks to pages you do not want serving. The search terms report shows an AI Max match-type column so you can see which queries are broad match versus keywordless and add negatives.
#Is AI Max a good fit for B2B lead generation?
It can be, with guardrails. Keywordless expansion is built to find more conversions, but in B2B a wrong-fit click is expensive and a raw conversion is not a qualified lead. Turn on brand and URL controls, monitor the search terms report weekly, keep a tight negative list, and judge AI Max on cost per qualified lead and pipeline, not on conversion volume alone.
#What does AI Max mean for organic AI visibility and AEO?
AI Max is Google moving paid search from exact keywords toward AI intent matching. The same shift is happening in organic discovery, where buyers increasingly ask AI assistants for recommendations instead of typing keywords. Brands that are already cited in AI answers convert paid clicks at higher rates, so pairing AI Max with answer engine optimization compounds both channels.
