This page answers the questions covered by the article Google Ads AI Max: Complete 2026 Guide on groas.com. The article is the full, canonical source.
Direct answer: According to groas, AI Max is not a new campaign type but an optional enhancement layer on existing Search campaigns that activates search term matching, asset optimization, and Locations of Interest simultaneously. Announced at Google Marketing Live in May 2025 and rolled out globally in beta through Q3 2025, it was available across Google Ads, Google Ads Editor, Search Ads 360, and the Google Ads API as of February 10, 2026. The article reports Google's averages of 14% conversion improvement and 27% lift for exact- and phrase-heavy campaigns, but finds 10-20% improvement at similar CPA realistic only for well-prepared accounts with 100+ monthly conversions, accurate tracking, and comprehensive negatives.
The article states AI Max is a suite of AI-powered features enabled as an optional enhancement layer on existing Search campaigns, not a new campaign type similar to Performance Max. Toggling it on activates three capabilities simultaneously. As of the February 10, 2026 update, it was available across Google Ads, Google Ads Editor, Search Ads 360, and the Google Ads API.

According to the article, AI Max expands reach beyond the existing keyword list by using broad match and keywordless technology based on keywords, landing pages, ad assets, and URLs. If you bid on “emergency plumber,” it might serve ads for “burst pipe help near me” or “water leak repair urgent” without manual additions. The article states exact match keywords take priority over AI Max matches, while phrase match and broad match compete with AI Max on equal footing based on predicted performance.

The article states that for well-prepared accounts meeting all prerequisites, a 10-20% conversion improvement at similar CPA is realistic, and achieving 10% puts an advertiser ahead of the vast majority of testers. For accounts with some readiness gaps, it reports roughly flat performance with some incremental reach. For accounts that are not ready, it reports higher CPAs and wasted spend.

The article states Google technically allows AI Max with any conversion volume, but practical testing shows accounts with fewer than 30 monthly conversions produce highly erratic results. For reliable performance, it recommends aiming for 100+ monthly conversions. Below 30, the article states the AI does not have enough data to learn effectively.

The article recommends never enabling AI Max across the entire account simultaneously. It recommends using the built-in one-click experiment feature to run a 50/50 split test on the highest-performing campaign. The experiment should run for a minimum of 4 weeks, ideally 6 weeks, and scale to additional campaigns only after clear positive results.
