Summary

AI Max is expanding from Search to Shopping campaigns. It is now globally available, covering all markets and languages. For retailers, this means Google AI takes broader control over targeting and creative formats, in exchange for (Google says) stronger conversion performance. The key questions are: do you qualify, what control do you give up, and is now the right time to opt in? This post covers what is actually changing, what the data shows so far, and a simple framework for deciding whether to move now or wait.

What is AI Max for Shopping? {#what-is-ai-max-for-shopping}

Google announced AI Max at Google Marketing Live 2026. For Search, it came out of beta in April 2026. For Shopping, the expansion was announced at GML and is now generally available, global, across all languages.

The idea is straightforward. AI Max hands more of the campaign decision-making to Google’s AI: where your ads show, what format they take, and how they match to queries. In return, you are supposed to get more conversions or conversion value without paying a higher CPA or sacrificing ROAS.

On Search campaigns, the data looks reasonable. Google’s own figures (Global, 2026, non-Retail) show an average of 7% more conversions or conversion value at similar CPA/ROAS when AI Max uses search term matching. That is an internal stat, so take it with appropriate scepticism. But 7% is a real number and specific enough to be worth noting.

For Shopping specifically, Google is pitching AI Max as giving retailers “the best of Google AI and new formats.” Vague, yes. But the mechanism is the same as Search: AI expands what it can show, where, and to whom, with you setting the guardrails.

What does it actually change in your campaigns? {#what-does-it-actually-change}

This is where retailers need to pay close attention.

With standard Shopping campaigns, you control quite a lot. Negative keywords keep irrelevant queries out. Bid adjustments let you push harder on certain products or audiences. You can split campaigns by margin or product category and manage them separately.

AI Max changes that balance.

Google’s AI takes on more of the matching and targeting decisions. That means you are trading granular control for (in theory) better coverage of relevant demand that your current structure might be missing. Whether that trade is worth it depends entirely on your setup and your feed quality.

There are also two new features worth knowing about, announced alongside the AI Max expansion:

AI Brief. This gives you a way to direct Google’s AI on creative. You tell it your brand tone, messaging priorities, and any constraints. It is not a full creative brief in the traditional sense. Think of it as a set of guardrails that influence how the AI writes copy.

Text disclaimers. When final URL expansion is active, Google can now include legally required disclaimer text in your ads automatically. This is specifically useful for regulated industries: finance, pharmaceuticals, legal services. If you have always avoided URL expansion because disclaimers could not be guaranteed, this removes that barrier.

Should you turn it on now? {#should-you-turn-it-on-now}

Honest answer: it depends on three things.

1. Feed quality. AI Max for Shopping runs on your product feed. If your titles, descriptions, and attributes are weak, the AI does not have good material to work with. Turning on AI Max over a poor feed is not going to fix a targeting problem, it will likely make it worse. Clean the feed first.

2. Current performance. If your Shopping campaigns are already hitting target ROAS and you have a well-structured account, there is no fire here. Test AI Max in a lower-priority campaign or a single product category before rolling it out broadly.

3. Your tolerance for reduced visibility. This is the honest part that Google tends to downplay. With AI Max, you see less about where your ads are showing and why. If you run audits for clients (as I do) you already know how hard it can be to diagnose performance issues in campaigns where control has been handed to automation. You need strong conversion tracking before you hand the keys over. If your tracking has gaps, fix them first. Otherwise AI Max will optimise toward the wrong signals.

I had a client a while back, mid-size retailer, decent feed, reasonable ROAS. We moved a campaign to a fully automated setup before the tracking was solid. Conversion data was coming in 30-40% inflated due to a tag firing issue on a thank-you page redirect. The AI saw great results and spent hard. Real sales told a different story. We spent four weeks unwinding it. That kind of mistake costs real money and real time.

Strong tracking. Clean feed. Then test AI Max in one segment. That is the sequence.

Travel Ads: the other Shopping expansion {#travel-ads-the-other-shopping-expansion}

Alongside AI Max for Shopping, Google also announced AI Max coming to Travel Ads in Search campaigns.

This matters if you run hotel, flight, or travel inventory through Google. The expansion means AI Max’s targeting and format capabilities will be available for Travel Ad formats, not just standard text or Shopping.

The detail here is thin from what Google has shared publicly. The mechanism mirrors what is happening in Shopping: Google AI takes on more of the heavy lifting for matching and format selection. For travel advertisers already running Performance Max or Hotel campaigns, this is worth watching but not necessarily worth acting on immediately.

FAQ {#faq}

Is AI Max for Shopping available now?

Yes. It was announced at Google Marketing Live 2026 and is now generally available. Global rollout, all markets, all languages.

Does AI Max for Shopping replace Standard Shopping campaigns?

No. It is a feature layer you opt into, not a replacement campaign type. You can choose whether to enable it.

What control do I keep with AI Max for Shopping?

You retain budget control, your product feed structure, and the ability to use negative keywords at the account level. What you give up is granular control over where and how your ads match to queries. Google’s AI takes on those decisions.

What is the AI Brief feature?

AI Brief is a new control announced alongside the AI Max expansion. It lets you give Google’s AI directional input on how your creative should sound and what it should prioritise. It does not replace ad copy. It shapes how the AI generates and tests copy on your behalf.

Should I enable AI Max across all my Shopping campaigns at once?

No. Test in one campaign segment first. Make sure conversion tracking is solid and your feed is clean before expanding. The 7% conversion uplift figure Google cites is an average across Search campaigns. Shopping will have its own performance profile. Treat it as a test until you have your own data.

Next steps {#next-steps}

If you want to know whether AI Max for Shopping makes sense for your account specifically, the place to start is understanding what your current Shopping setup looks like and where the gaps are.

A Google Ads audit will show you feed quality, tracking gaps, and campaign structure issues before you hand more control to Google’s AI. That is the right order.
