AI Max for Search is now on in every market. It widens reach, removes match-type control and changes what your reports can tell you. Here is what to change this week.
Google finished the global rollout of AI Max for Search campaigns on Thursday, six months after the first US pilot. The feature bundles broad-match expansion, automatically generated assets and final-URL expansion into a single toggle, and that toggle is now on for every new campaign.
The company's framing is simple: more relevant reach with less setup. The framing is accurate. It is also incomplete, because the setup it removes is the setup most performance teams use to explain their numbers.
Three mechanics moved at once. Search-term matching now uses the intent model that powers Performance Max rather than the keyword list. Headlines and descriptions are generated from landing-page content when the system thinks it can do better than yours. And the final URL can be swapped for any page on the domain the model believes converts better for that query.
By week twelve, more than half of pilot spend sat on queries that no one had chosen. That is not a problem in itself; several accounts saw CPA improve. The problem is attribution of credit. When the query, the ad copy and the landing page are all selected by the system, the keyword-level report becomes a description of what the model did, not a lever you can pull.
“Reach is being offered at the price of control. Take the reach. Write down what you gave up.”
Heads of Performance whose targets are set at keyword or ad-group level. Ecommerce directors with brand-protection rules that depend on exact match. Anyone presenting Search results to a board using last-click CPA. Agencies will feel it first, because the client's question will change from “why did this keyword move?” to “why did the system do that?”, and the second question needs different evidence.
“Automation is not the risk. Delegating judgement to it is. Turn AI Max on where you have clean conversion data and brand exclusions that you have tested. Leave it off where the landing page is the product, because the model will happily send people somewhere else.”
