One helps you get more from Search. The other takes your ads across Google’s channels. So, which one is right for your business?
Google Ads is becoming increasingly AI-driven, giving advertisers more ways to reach potential customers. But with AI Max for Search and Performance Max, it’s easy to assume both tools do the same thing.
They don’t.
AI Max enhances your existing Search campaigns with AI-powered features that help you reach relevant users beyond your traditional keyword targeting. Performance Max takes a broader approach, using AI to run ads across Google’s advertising channels.
The difference matters because the right campaign setup depends on your goals, budget, and how much control you want over your advertising.
Let’s break down what sets them apart and how to decide which one works best for your business.
Smarter Search or Advertising Across Channels?
AI Max: Get more out of Search. Already running Google Search campaigns? AI Max helps you discover additional relevant queries, adapt ad messaging, and direct users to suitable landing pages through features such as search term matching, text customisation, and Final URL expansion. You can also use available controls and search-term reporting to monitor performance.
Performance Max: Reach customers across Google. Performance Max is a standalone campaign type that uses AI to optimise ad delivery across channels such as Search, YouTube, Display, Gmail, Discover, and Maps. You provide your campaign goals, budget, audience signals, and creative assets, while Google automates much of the targeting and delivery.
Control versus reach. AI Max is a natural option when Search is central to your strategy, and you want greater visibility into search queries. Performance Max is designed to find conversion opportunities across multiple channels, with less direct control over individual placements and targeting decisions.
Your campaign data still matters. Neither option guarantees better results simply because AI is involved. Reliable conversion tracking, relevant audience data, strong landing pages, and clear campaign goals all influence performance. Performance Max also benefits from a good range of creative assets, while AI Max builds on your existing Search campaign setup.

FAQs
What is the main difference between AI Max and Performance Max?
AI Max adds AI-powered features to existing Google Search campaigns to improve query matching and ad relevance. Performance Max is a separate campaign type that uses AI to deliver ads across multiple Google channels.
Which is better for B2B and lead generation?
AI Max can be a good fit for businesses focused on high-intent Search traffic and qualified enquiries. Performance Max may also help when you want to reach potential customers across additional channels. Your choice should depend on lead quality, conversion tracking, and business objectives.
Can I run AI Max and Performance Max together?
Yes. Both can run in the same Google Ads account. Define their roles clearly and monitor performance to understand how each contributes to conversions. Overlapping targeting doesn’t automatically mean the campaigns compete in every auction, so assess actual results rather than assuming conflict.
Does AI Max require new images or video assets?
AI Max can work with your existing Search campaign setup, using features such as text customisation and Final URL expansion. Performance Max generally benefits from a broader set of creative assets, including images and video, to support its multi-channel delivery.
How should I test AI Max before increasing my budget?
Start with an established Search campaign that has reliable conversion tracking. Where available, use a Google Ads experiment to compare your existing setup with an AI Max-enabled version. Evaluate search-term relevance, conversion quality, acquisition costs, and revenue before deciding whether to scale.
