What Google Marketing Live 2026 means for Search advertisers, and why AI Brief might be the most strategic feature you haven't used yet.
Search has always been your ultimate performance powerhouse, and Google just made it your discovery engine, too. At Google Marketing Live 2026, held on May 20th, Google made it clear that the era of keyword-matching your way to ROI is officially over. The future is conversational, agentic, and driven by AI that can now interpret the nuance behind what your customers are actually asking.
The headline? AI Max—Google's fastest-growing AI-powered Search ads product—is expanding beyond Search campaigns and into Shopping and Travel. Paired with a new tool called AI Brief that finally lets you guide the AI in your own words, this is arguably the most significant shift to Google's campaign architecture in years. Here's what you need to know.
What Exactly Is AI Max?
For those who need a quick refresher: AI Max is Google's intelligence layer for Search-style campaigns. It combines three core capabilities—search term matching, text customization, and Final URL Expansion—to help your ads surface against the kind of long, conversational, intent-rich queries that keyword lists can't reliably catch.
Think of it this way: when someone types "best waterproof running shoes for wide feet under $150 that ship fast to Toronto," no traditional keyword will match that cleanly. AI Max can. And it's not just showing up—it's showing up with dynamically generated copy that speaks directly to what that person asked.
Since its launch, AI Max for Search campaigns has delivered an average of 7% more conversions or conversion value at a similar CPA or ROAS when advertisers use the full feature suite. That's not a small bump. That's meaningful incremental performance sitting on top of campaigns you're already running.
The GML 2026 Expansion: Shopping and Travel Are Now In
Announced on the eve of Google Marketing Live, the expansion of AI Max to Shopping campaigns and Travel Ads is a big deal, especially for retailers and travel brands that have historically been limited by the constraints of traditional campaign structures.
New Announcements at GML 2026
-
AI Max for Shopping
- Dynamically matches your Merchant Center feed to conversational queries. One-click toggle from your existing campaigns.
-
Search Campaigns for Travel
- Consolidates hotels, flights, and car rentals into a single campaign with unified reporting and AI Max capabilities.
-
AI Brief

-
Ads in AI Mode
- Gemini-powered ad formats embedded directly inside Google's AI Mode in Search—conversational, contextual, and built for discovery.
For retailers, AI Max for Shopping generates dynamic ads directly from your Merchant Center feed to answer conversational shopping queries—queries that standard Shopping campaigns would have missed entirely because they're too specific, too long, or too nuanced for a product title to match. Google is calling this a one-click upgrade for immediate incremental reach, and for most Shopify or Merchant Center-connected advertisers, activation is straightforward.
For travel advertisers, the win is arguably even bigger. For years, running hotel, flight, and car rental ads on Google meant managing completely separate campaign types, each with its own bidding logic, reporting interface, and feed setup. That produced fragmented data, made cross-format budget decisions unnecessarily complicated, and meant AI-powered tools were only partially available. Search Campaigns for Travel consolidates all of that into a single campaign, with unified reporting and full AI Max capabilities available across every travel format.

AI Brief: Finally, a Way to Guide the AI Without Losing Your Voice
The feature I'm most excited about—and the one I think is most underappreciated in the initial coverage—is AI Brief. This is Google's direct response to one of the most consistent complaints advertisers have had about AI-driven campaigns: the "black box" problem. When you hand your messaging to an algorithm, how do you make sure it still sounds like your brand?
AI Brief, powered by Gemini, lets you provide a plain-language briefing to guide how AI Max generates your ads and targets your searches. You can tell the system what your business does, what tone it should use, which audiences to prioritize, and what the AI should avoid. For example, don't lead with pricing, or always reference free shipping for Canadian orders. The system then generates ad and search match previews so you can review and refine before anything goes live.
This is a meaningful shift. It moves the advertiser relationship with Google's AI from "set it and hope" to a genuine creative collaboration. Think of it like briefing a smart, fast junior copywriter who never sleeps—you bring the brand knowledge and strategic direction, and the AI brings the scale and adaptability.
AI Brief is rolling out in English for AI Max for Search campaigns first, followed by Performance Max and AI Max for Shopping campaigns. If you're already running AI Max, your existing text guidelines will automatically migrate into the AI Brief framework when you activate it.
Ads in AI Mode: Search Has a New Front Door
Alongside the AI Max expansion, Google announced new Gemini-powered ad formats built specifically for AI Mode in Search—the conversational, multi-turn search experience that's becoming the primary discovery surface for a growing number of users. These formats are designed to make ads feel like helpful additions to a conversation rather than interruptions. They're contextual, tailored to the specific query, and built to close the gap between a person's initial question and their final purchase decision.
For advertisers, this matters because the intent signals in AI Mode queries are often richer and further along the purchase journey than a standard keyword search. Someone asking "what's the best family-friendly all-inclusive in Mexico for March with a toddler and a teen?" is not browsing. They're ready to book. If your travel brand isn't showing up in that conversation, you're invisible to one of your highest-value prospects.

What You Should Be Doing Right Now
Google's pace of change at GML 2026 was significant, and the window to act early is still open. Here's how to prioritize:
First, if you're running Shopping campaigns, evaluate your Merchant Center feed quality before enabling AI Max. The AI is only as good as the data you give it—accurate inventory, detailed attributes, clear pricing, and specific product descriptions are what allow the system to match your products to conversational queries with confidence. Messy data means missed auctions.
Second, start drafting your AI Brief now, even before it's available in your account. Write down your brand tone, your key audience personas, your messaging priorities, and a short list of things the AI should never say or imply. Having that brief ready means you can activate quickly and with intent when the feature rolls out to your campaign types.
Third, for travel advertisers: plan for the migration to Search Campaigns for Travel. The consolidation is designed to be a simplification, but it's worth reviewing your existing campaign structures, bidding strategies, and budget allocations before the shift so you don't lose performance momentum during the transition.
The fundamental promise of AI Max—across Search, Shopping, and now Travel—is that Google's AI handles the impossible complexity of matching every unique query to the right ad, while you maintain the brand guardrails, the business logic, and the strategic direction. That's a healthy division of labour, and AI Brief is what makes it actually work in practice.
Google Marketing Live 2026 sent a clear message: the brands that grow fastest in the age of AI won't be the ones who resist automation. They'll be the ones who learn to direct it well.
The expansion of AI Max is the most significant shift in paid media in years, and implementing AI Max campaigns correctly is crucial for your SEM marketing success.
