On May 6, Google introduced AI Max for Search campaigns, a one-click bundle of AI targeting and creative features for Google Ads. The headline is reach: your ads start showing on searches your keyword list never covered. The fine print is control, and control is where most of the budget is won or lost.
What Google announced
AI Max is not a new campaign type. It is a suite you switch on inside a Search campaign you already run. Google describes it this way:
Introducing AI Max for Search campaigns, a comprehensive suite of targeting and creative enhancements that brings the best of Google AI to help you take your Search campaigns to the next level.
Three parts do the work. Search term matching uses broad match and "keywordless technology" to find queries your keywords miss. Text customization generates new headlines and descriptions from your landing page, ads, and keywords. Final URL expansion sends each click to the most relevant page on your site instead of the single URL you set.
Google published launch performance figures in the same announcement:
The data already shows that advertisers that activate AI Max in Search campaigns will typically see 14% more conversions or conversion value at a similar CPA/ROAS. For campaigns that are still mostly using exact and phrase keywords, the typical uplift is even higher at 27%.
Beauty company L'Oréal is cited as an early case: after turning on search term matching, Google reports a 2X higher conversion rate at a 31% lower cost-per-conversion. A second example, the Australia-based utility connection service MyConnect, drove 16% more leads at a 13% lower cost-per-action, with a 30% increase in conversions specifically from net-new queries.
In plain English
The old model had three fixed points. You picked the keywords, Google matched searches to them, and you wrote the ad. AI Max loosens all three at once. It decides which searches to enter (past your keyword list), rewrites the ad text to fit the search, and picks the landing page.
That is powerful and risky in the same move. More reach means more queries you did not choose, and some of them are off-target. Auto-generated headlines can drift from how you actually describe your product. Final URL expansion can route a click to a page you would never have picked for it. Google knows this, which is why the same launch ships a set of controls.
Why this matters for your business
Reach without control burns budget. The controls are the real product here, and Google says so directly:
AI Max comes with new controls that give you the precision you previously used keywords for.
Those controls include brand controls at the campaign and ad group level, so you can name the brands your ads should appear alongside or block the ones they should not. Locations of interest lets you reach customers by geographic intent at the ad group level. A new URL parameter reports search terms across every match type, so you can actually see what AI Max matched you to and prune what is leaking spend.
Here is the trap. Switching AI Max on is one click. Configuring the brand controls, reading the new search terms every week, cutting the queries that waste money, and keeping the generated copy on message is ongoing operator work. The 14% and 27% uplift figures assume someone is doing that work. Turn it on and walk away, and the reach that was supposed to help you spends quietly against searches that never convert.
Notice that both case studies above have the same shape: an advertiser turned AI Max on and then managed it toward a specific result. The uplift did not come from the switch alone. It came from pairing the broader matching with the new reporting, watching what the system actually did, and steering it back on course when it wandered. That management is not optional overhead on top of the tool. It is how the tool produces the numbers Google is quoting.
Where Trinzik fits
This is the kind of account we run for clients every day. Our paid search work treats AI Max as a tool to be steered, not a switch to be flipped. We set the brand and location controls before launch, read the search-term reports on a schedule, cut the queries that leak budget, and keep the auto-generated copy aligned with the client's voice. The point is to capture the incremental reach Google is offering without paying for the reach you do not want.
If your Search campaigns are still keyword-only, the gap Google describes is real and it is measurable. Talk to us about a controlled migration that keeps you in charge of where the money goes.
Questions this raises
What conversion uplift does Google claim for AI Max in Search campaigns?
Google's May 2025 launch data shows advertisers that activate AI Max in Search campaigns typically see 14% more conversions or conversion value at a similar CPA or ROAS. For campaigns still mostly relying on exact and phrase keywords, Google reports the typical uplift is higher still, at 27%.
What are the three parts of AI Max for Search campaigns?
AI Max bundles three features inside an existing Search campaign: search term matching, which uses broad match and keywordless technology to find queries a keyword list misses; text customization, which generates new headlines and descriptions from your landing page, ads, and keywords; and final URL expansion, which routes each click to the most relevant page on your site.
What controls does Google offer to keep AI Max from going off-target?
Google pairs AI Max with brand controls at the campaign and ad group level to name or block specific brands from appearing alongside your ads, locations of interest to target by geographic intent at the ad group level, and a URL parameter that reports the search terms AI Max actually matched, so an advertiser can see and prune queries that are not converting.
