AI Max

in English: AI Max for Search campaigns

advancedspreading

The Google Ads switch that lets artificial intelligence decide on which searches, with what text, and pointing to which of your pages your ad should appear.

In plain terms

AI Max is not a separate campaign type but a feature package that you can switch on in your existing Google Search campaign. Until now, you listed the keywords you wanted to appear for. Now Google's artificial intelligence also finds matching searches itself, based on your website and ads.

It is like not giving a store clerk memorized lines but trusting them with the customer. The clerk listens to what the customer is looking for, answers in their own words, and walks them to the shelf where they are most likely to find it. The clerk serves more customers, but does not always say what you would have said.

It became important because people are asking search engines longer, conversational questions that are hard to cover with pre-set keywords. According to Google, AI Max also helps ads appear on AI-based search surfaces, such as AI Overviews.

How it works

You turn on AI Max in the search campaign settings; your existing keywords, ads, and budget remain unchanged.
The system displays your ad for related searches based on your keywords, ad copy, and website content, including those you did not specify.
The ad adjusts its headlines and descriptions to the specific search: it creates new versions from your existing text and your page content.
It directs the visitor to the subpage of your website that it deems most suitable for the search, not necessarily the one you specified.
You can set limits (excluded sites, brands, geographic focus), and you can separately disable text rewriting and landing page replacement. In the reports, you can see for which search, with which text, and pointing to which site the advertisement appeared.

An everyday example

A bicycle shop in Budapest advertises only on the keyword 'buy electric bike'. With AI Max enabled, the ad may also appear to someone who types: 'How should I commute 15 kilometers to work if I do not want to sweat?' The headline adjusts to this question, and the click leads to the page of e-bikes intended for commuters.

Who is affected

A common misconception

MythAI Max is a new, standalone campaign type that fully replaces keywords and the advertiser's manual work.

In realityA feature package that builds on an existing search campaign and can be switched on or off. Your keywords remain, and a proper website, accurate measurement, and human oversight are still required for good results.

Limits and risks

You have less direct control: ads may appear for searches you did not select, so review search terms regularly.
Automatically generated text may be inaccurate or misaligned with your brand, and if your website is outdated, the advertisement will be too. Pay special attention to this in regulated sectors (finance, healthcare).
It optimizes well only if you measure precisely what counts as a result for you (purchase, quote request); with poor measurement, it learns in the wrong direction.
The performance improvement published by Google is an average; it can differ significantly in your own account, so it is worth introducing it as an experiment, with comparison.

Similar, but not the same

Performance Max – Performance Max is a standalone campaign type that advertises on almost every Google surface (e.g., search, YouTube, Gmail, Maps, display network), while AI Max only expands search campaigns.
Broad match keyword – Broad match only expands which searches you appear in, while AI Max also adapts the ad text and landing page to the search.
AI overview – AI Overviews are summary responses generated by Google's AI, typically appearing at the top of search results. AI Max, by contrast, is an advertising tool that allows ads to appear on such surfaces.

A brief history

Google announced the AI Max for Search campaigns feature package in May 2025 and began its global, beta-labeled rollout later that month. It builds on previous automation solutions, such as broad match, automatically created ad assets, and dynamic search ads.

Where things stand

By the end of 2026, it is widely available in Google Ads accounts, strongly recommended by Google, and tested or used by many advertisers. The industry is divided: larger reach is praised, while declining control and transparency are debated.
