Google's AI Max Is Bringing New Potential to Your Campaigns – Here's What You Need to Know
If you're running Google Ads in 2026, it's important to know how AI Max is reshaping marketing strategies. Search is already moving further towards automation, with major changes expected from September. Shopping and Travel are also entering this AI Max movement, showing that Google's automation push is moving beyond traditional search activity.
Here's what's changing, what it means for your campaigns, and what you should do about it.
What is AI Max?
According to Google, AI Max "offers a comprehensive set of AI-powered features that help you find more customers and drive performance by matching your ads and landing pages to a user's intent".
Instead of manually managing keywords, AI Max uses search term matching, text customisation, and final URL expansion to help Google match ads to broader searches, adapt ad copy, and select relevant landing pages to drive traffic to. Users only need to provide inputs such as conversion goals, creative assets, and budget and bidding strategy, and then Google's AI supports the matching and optimisation process.
Google says AI Max is their fastest-growing AI-powered Search ads product. As of April 2026, it covers Search campaigns, which will become mandatory by September, along with Shopping and Travel campaigns, which are currently in beta globally. They're pushing more users towards AI Max.
The Big Change – Dynamic Search Ads Are Being Retired
If you're running Dynamic Search Ads (DSA), Automatically Created Assets (ACA), or campaign-level broad match, you have until September 2026 before Google forces this change.
What are the potential trade-offs?
Implementing AI Max brings significant automation, but it comes with several challenges that can impact your campaign if not managed carefully.
- Dynamic ad copy assembly: While you provide headlines and descriptions, AI generates variations and decides which ones to show for each search. You can't control which specific combinations appear for which queries.
- Potential mismatch between query intent and landing page: AI Max can route traffic to more relevant URLs across the domain rather than the exact page you chose, unless you disable Final URL Expansion (FUE).
- Loss of manual control: AI automates several aspects of the ad process, reducing direct control over bidding and placements. You can see which searches triggered your ads in reports, but you can't control which searches trigger them in advance. AI might show your ads for searches you consider irrelevant, which might waste budget on low-quality traffic.
What do you still control?
You're not handing over everything. Here's what stays in your control with AI Max
- Budget and bidding strategy: Your daily budget caps, overall spending limits, and target ROAS stay in your hands. AI optimises within the boundaries you set.
- Conversion goals: You define what counts as success—whether that's purchases, leads, sign-ups, or phone calls. The AI optimises toward your chosen conversions.
- Negative keywords: After reviewing search term reports, you can block specific searches from triggering your ads. This helps you eliminate budget waste on irrelevant queries.
- Text Disclaimers: A key benefit for advertisers in regulated industries or anyone needing strict text control. Text Disclaimers allow you to add legally required disclosures that always appear in your ads. They are compatible with all AI Max features, including FUE and Text Customisation. This means you can utilise FUE to choose the most relevant landing page for each search and still be confident that your disclaimers will show.
- AI Brief and Audience Guidance: Powered by Gemini, AI Brief is rolling out in English for AI Max for Search campaigns, with Performance Max and AI Max for Shopping campaigns to follow. It lets advertisers use their own words to guide AI Max with messaging, matching and audience guidelines. These act as guidance for Google's AI, rather than strict targeting rules.
Will Performance Improve or Drop?
To be honest? It depends. Google says AI Max delivers 7% more conversions when you enable all three features compared to using just search term matching.
Other studies show a messier picture. An analysis of 250+ campaigns found median revenue increased 13% but with a 16% higher CPA. This means that there are more sales, but advertisers are paying more for each one. Another test across 23 accounts showed a 40% higher success rate with all three AI Max features enabled. But the third found 99% of AI Max impressions generated zero conversions. A test running AI Max for 5 months reported strong top-of-funnel volume but fewer quality sales conversions compared to Phrase / Exact campaigns.
Here's what seems to be happening: AI Max brings volume, but not always quality. It finds more searches, yet many of them drive clicks without sales. Results vary by account structure, tracking setup, and how closely you monitor what AI Max is actually doing.
What's Coming Next? AI Max For Shopping & Travel
Search is just the beginning. Google announced AI Max is expanding to Shopping and Travel campaigns, showing how automation is set to play a bigger role beyond traditional Search activity. It's a change well worth keeping on the radar.
AI Max for Shopping
For Shopping campaigns, AI Max will use product feeds to match ads with more conversational searches. For example, instead of appearing for a specific query like "Nike Air Max 270", your ad could show for a broader search like "comfortable running shoes for wide feet", capturing complex, long-tail search terms.
AI Max for Shopping also includes Optimal Format Selection, which automatically chooses between text ads or Shopping ads based on what's most relevant to the shopper's intent at that moment. If you're already running Shopping campaigns, you can upgrade to AI Max in one click while keeping your existing product targeting and bidding controls.
AI Max for Travel
Before AI Max, hotel, flight and car rental campaigns often sat in separate places. With AI Max in place, Google is moving towards a more consolidated setup: Search Campaigns for Travel that brings all travel activity, reporting, and automation into a single campaign structure. You get a real-time optimisation using your feed data or keywords alongside AI Max features, and unified reporting. This can simplify workflows while providing you with a clearer view of performance.
What AI Max Means for Your Business
The role of paid search is changing and AI Max is not a standalone update. It is part of Google's bigger move towards automation, building on the direction already set by Performance Max and other automated Search features.
Success will depend less on manual keyword control and more on the strength of your campaign structure, conversion data, landing page relevance, and feed accuracy. That does not mean handing everything over to Google and hoping for the best. The businesses that get the most from AI Max will be those that prepare early for the change and keep a close eye on where automation is helping or hurting performance.
