Google AI Max for Search:
What Every Marketer
Must Do Right Now
The biggest change to paid search since Smart Bidding. Here is what AI Max is, how it works, who should use it, and what you must do in your account today.
Google AI Max for Search: The Biggest PPC Change Since Smart Bidding
AI Max for Search is not a new campaign type -- it is a suite of AI features that can be enabled within existing Search campaigns, fundamentally changing how your ads match, target, and bid.
AI Max matches your ads to a dramatically wider range of search queries -- including long-form conversational queries generated by users interacting with Google's AI search interface. Your existing keywords become signals rather than hard-match requirements.
AI Max automatically selects the most relevant landing page from your website for each query -- not just your specified final URL. This improves message-to-query match and landing page relevance scores without requiring manual URL management.
AI Max generates query-specific ad copy variations using your existing headlines, descriptions, and website content. Each user sees an ad version optimised for their specific search intent rather than a generic RSA.
AI Max uses your customer lists and audience signals to prioritise audiences most likely to convert -- applying this intelligence across the expanded query set to find high-value users even in queries you would not have manually targeted.
AI Max essentially extends Broad Match with AI-driven intent inference. It understands the meaning behind queries rather than just the keywords used -- matching to searches that contain the same intent as your target keywords expressed in different words.
AI Max includes search term transparency reporting, URL exclusions to prevent expansion to unwanted pages, and audience signal controls. You have more visibility than Performance Max while accessing broader automated optimisation than standard Search.

How to Enable AI Max for Search
AI Max is enabled at the campaign level within existing Search campaigns -- not as a new campaign type. To activate it, go to your Search campaign settings, find the Additional features section, and enable AI Max. You will be prompted to set your URL expansion preferences and customer list connections before the feature activates.
What to Do Before Enabling
Before turning on AI Max, complete three tasks. First, ensure your negative keyword lists are comprehensive and up to date -- AI Max expands your query set and without strong negatives, it will pull in irrelevant traffic. Second, upload your customer lists to Google Ads and connect them as audience signals. Third, verify your conversion tracking is firing correctly -- AI Max needs clean conversion data to make good expansion decisions.
What to Watch After Enabling
Monitor your search term report weekly for the first month. AI Max will surface query types you have never bid on before -- some will be relevant and converting, some will not. Build your negative keyword list continuously based on this data. Also watch your average position and quality scores across your top terms -- URL expansion can occasionally dilute landing page relevance scores if not monitored.
AI Max in one line: It is Smart Bidding plus Broad Match plus dynamic ad copy plus URL expansion, all working together. If you have been hesitant to use Broad Match because of quality concerns, AI Max addresses most of those concerns with better intent understanding and audience signal integration.

Google AI Max for Search FAQ
AI Max for Search is a suite of AI features enabled within existing Search campaigns that expands query matching to include conversational and intent-based searches, automatically selects the best landing page from your site, and generates query-specific ad copy variations.
No. Performance Max runs across all Google channels -- Search, Display, YouTube, Shopping, Discover, and Gmail. AI Max for Search is contained to the Search network and gives advertisers more control and transparency than PMax while accessing AI-driven optimisation beyond standard keyword targeting.
Minimum 15 weekly conversions per campaign before enabling AI Max. Below this the AI lacks sufficient data to make good query expansion and URL selection decisions. Campaigns below this threshold are better served by standard Search with exact and phrase match.
AI Max can expand to queries outside your exact keyword list. Strong negative keyword lists are essential before enabling. Monitor your search term report weekly for the first month and continuously build negatives based on irrelevant queries that appear.
AI Max performs best on campaigns with $100+/day budget and 15+ weekly conversions. Smaller budgets and lower conversion volume reduce the AI's ability to learn and optimise effectively. Standard Search campaigns with exact and phrase match are often better for smaller budgets.
