Google Is Now a Layer Between Your Store and Your Customer

Google Marketing Live happened this week. Most of the coverage landed in the usual places: ad performance benchmarks, bidding strategy updates, creative format changes. The announcements that matter for Shopify merchants are about where the transaction happens and who controls the path to it.

The Universal Cart: Google Between Search and Checkout

Google co-developed something called the Universal Commerce Protocol with Shopify, Amazon, Walmart, Meta, Stripe, Visa, and others. It’s an open standard that lets a shopping cart travel across sites. The Universal Cart, a cross-merchant cart that lives inside Google Search, the Gemini app, YouTube, and Gmail, started rolling out in the US on May 19.

A customer can find your product on Google, add it to a cart that lives on Google, compare it against other merchants, track price changes, and check out without visiting your store. Or they can transfer the cart to your site and complete the purchase there.

The convenience is real for buyers. For merchants, it means Google now sits between the search result and the transaction in a way it hasn’t before. Your product feed in Merchant Center is your presence in this layer. If it’s thin, inconsistent, or out of date, you lose visibility before a buyer ever considers clicking through to your store.

I’ve been running a third-party feed management app on my own stores for exactly this reason. It lets me write Boolean rules to control how product titles and attributes get formatted in the feed, rather than passing whatever Shopify exports to Google as-is. I also use it to create and manage promotions directly in Merchant Center without touching the store backend. The result is a feed that’s structured the way Google’s systems actually read it, not the way my internal naming conventions happen to work. The difference in impression share and click quality is real.

There’s a related shift worth understanding here. At GML, Google demoed a search query that would have been laughable two years ago: “I’m looking for a walking pad for my home office. I love hiking. I want it to be reliable and quiet. What are the best options for me?” That’s not a keyword. It’s a conversation with specific personal criteria, and Google surfaced a ranked comparison table in response. 75% of people say they make faster, more confident purchase decisions when they use AI overviews and AI mode. By the time someone clicks through to your store, the research is done. They’re not deciding anymore, they’re confirming. Your product page and your feed need to match what the AI already told them about you.

What to do: Audit your Merchant Center feed before this rollout gets wider. At minimum, make sure titles describe the product the way someone would search for it, attributes are filled in consistently, and pricing and availability are accurate. If you’re running any meaningful volume through Google Shopping, a feed management tool that gives you rule-based control over the output is worth looking at. It compounds as Google gives that data more weight.

Dynamic Search Ads Are Going Away in September

Dynamic Search Ads, a format that automatically generates ads based on your site content, will be migrated to AI Max in September 2026. The migration is automatic: if you’re running DSAs, they become AI Max campaigns in September regardless of whether you’ve reviewed or prepared them.

AI Max writes ad copy dynamically to match whatever someone is searching for and selects landing pages based on its own judgment. Practitioners are already flagging a consistent problem: it routes specific product queries to generic category pages instead of the matching product page. You pay for the click, the buyer lands somewhere that doesn’t answer what they searched for, and they leave.

If your product pages are clearly structured, with titles and descriptions that match how people search for the products, the AI has something accurate to work with. If they’re not, it’ll make poor routing decisions at your expense.

What to do: Before September, identify which campaigns use Dynamic Search Ads and understand how they’ll be migrated. If someone manages your Google Ads, ask them directly. Review your product page structure as well. The AI reads your site to make routing decisions, so the site needs to give it something useful to read. On the organic side, Google was explicit at GML about what surfaces in AI results: specific, first-hand content that only you can provide, not generic commodity descriptions. Reviews, expert takes, real usage context. Content written for agents and structured for easy navigation. That’s the SEO brief for 2026.

Direct Offers and AI Mode Shopping Ads

Google is now generating ad copy dynamically to match both the specific search query and the AI-generated answer that appears above paid results. They’re also introducing Direct Offers, exclusive discounts that surface at the moment someone has shown purchase intent inside an AI search result.

In both cases, Google is selecting which products to feature and writing the copy. The input you control is your product data. The merchants who appear well in these placements will be the ones with clean, specific, well-structured feeds. Vague titles and thin descriptions get passed over.

Google also announced AI Brief, which gives you brand-level control over how AI Max and Performance Max represent you. You describe your brand voice, your target audience, and the guardrails you want followed, in plain language, and it generates ad guidelines from that. You get previews to refine before anything goes live. If you’ve been hesitant to fully lean into AI Max because you don’t trust it to stay on-brand, this is the answer to that concern. Advertisers running AI Max or PMax are already seeing 15% more conversions at similar ROAS compared to campaigns that haven’t made the switch.

If you’re running Google Shopping and haven’t looked at your feed quality recently, this is the time.

YouTube Shoppable Ads Now Close the Sale on YouTube

UCP powers something new inside YouTube video ads. Retailers set up with UCP can now offer direct checkout from shoppable ads without the buyer ever leaving YouTube. A customer sees your product in a video ad, clicks the buy button, lands on a branded checkout screen with their shipping and payment pre-filled, taps Pay with GPay, and they’re done. The same frictionless path the Universal Cart creates on Google Search now exists inside YouTube video.

This matters because it removes the gap between the moment someone decides they want something and the moment they can buy it. That gap is where buyers talk themselves out of purchases, get distracted, or end up on a competitor’s product page. If you’re running YouTube campaigns and have UCP set up, this is worth testing. Product feeds in demand gen campaigns already drive 33% more conversions on average compared to campaigns without them — adding direct checkout removes the last friction point in that path.

What to do: If you’re running demand gen campaigns on YouTube, check whether your product feed is connected and whether your account is set up with UCP. The checkout capability will roll out to UCP-enabled retailers, so the setup work you do now carries forward.

Ask Advisor

Google announced Ask Advisor, a unified agent built with Gemini that works across Google Ads, Google Analytics, Merchant Center, and Google Marketing Platform. The idea is to ask it a question in plain language and have it connect the dots across those platforms in a single answer.

For a founder running their own marketing, or a small team with one person managing multiple platforms, the practical value is real. Getting an answer to “why did my cost per click increase last week and what should I change” from a tool that has access to both your Ads data and your Analytics data at once compresses a process that currently involves logging into several places and piecing together what happened manually.

It’s in early rollout. Worth having access to when it becomes broadly available. On the creative side, Pomelli — Google’s AI creative tool, which launched in October 2025 — got more stage time at GML. Its Catalog feature lets you point it at your product catalog URL and generate brand-consistent product shots and ad creatives in bulk. If you haven’t tried it yet, now’s the time.

How This Shapes What I Build

Announcements like GML feed directly into how I think about what to build next. The shift toward Google controlling more of the purchase path, and product data quality becoming the primary lever merchants have in that system, is something I factor into the tools I work on. I’m not building in reaction to one keynote, but the direction Google is moving confirms problems I was already thinking about.

Our Variant Discounts app exists partly because pricing strategy is becoming more visible in comparison-shopping environments. When a Universal Cart surfaces your price next to three competitors in a single view, how you structure discounts and tiered pricing matters more, not less.

Philipp Schindler closed his keynote segment with something called Jevons Paradox — an economic theory that says when technology makes a resource more efficient, consumption doesn’t go down, it goes up exponentially. His point: as AI makes it easier to search, people search more. As it gets easier to build creative, merchants create more. As measurement gets sharper, optimization accelerates. The game doesn’t shrink with AI. It expands. That’s the frame I’m carrying into everything we’re building.

Bottom Line: Audit your Merchant Center product feed, understand your Dynamic Search Ad exposure before September, and pay attention to how the Universal Cart develops through the summer rollout. Product data quality is the one variable you control in a system where Google is increasingly making the other decisions.
