According to Amazon’s Rufus announcement, more than 250 million customers used its AI shopping assistant in a single year, and shoppers who use it are over 60% more likely to buy on that trip. That is a purchase funnel run by software. Google, Meta and Amazon are all building AI shopping agents, and each one will decide what it knows about your brand from the data you hand over. This checklist covers what to audit first.
Three agents, three different data appetites
These are not the same product. Treat them as three separate integration problems.
Google is the most structured. Its announcement of the Universal Commerce Protocol describes an open standard for agentic commerce that covers discovery, buying and post-purchase support. It is compatible with the Agent2Agent, Agent Payments Protocol and Model Context Protocol standards. Google also said Business Agent is live with retailers including Lowe’s, Michael’s, Poshmark and Reebok. It answers shopper questions in a brand’s voice, and eligible U.S. retailers can activate it in Merchant Center.
Amazon is the most mature. Its Rufus announcement says the assistant draws on Amazon’s product catalog, customer reviews, community Q&As and information from across the web. That page notes Rufus was renamed Alexa for Shopping on May 13, 2026.
Meta is the least settled. Digital Trends reports that Meta is building an Instagram shopping assistant, and the tool is reportedly built on a model called Muse Spark. Everything about Meta’s agent is reported, not confirmed. Plan for it. Do not build on it yet.
Why should brand marketers care, not just ecommerce teams?
Because the agent now sits between your creative and the sale.
A creator’s review, a UGC video, a product claim in a caption: these become inputs to what an agent recommends. Amazon says its assistant uses retrieval from outlets like The New York Times, USA Today, Good Housekeeping and Vogue to answer product questions. Your earned and creator content is feeding the answer, whether or not you planned for it. We covered the visibility side in our piece on how answer engines cite creators.
An AI shopping agent never reads your brand book. It reads your product feed, your reviews and your claims, then decides what to say about you.
The data access checklist
Work through these in order. Each item names an owner, because most failures here come from nobody owning the problem.
1. Product feed integrity (owner: ecommerce or retail media)
- Audit titles, attributes and availability. Google says the best preparation for UCP is making sure everything in Merchant Center, from product feeds to brand assets, is robust and current.
- Check checkout eligibility flags. Per Google’s Merchant Center help page, only listings using the native_commerce(checkout_eligibility) product attribute display the “Buy” button in the new checkout experience.
- Reconcile prices. Amazon’s agent can auto-buy at a set price, and Amazon’s own examples include buying headphones at 30% off. Stale or inconsistent pricing across channels will show up fast.
2. Merchant of record and payment terms (owner: legal and finance)
Google’s help documentation says you remain the seller of record under UCP-powered checkout, which can happen directly on Google’s surfaces. Customers pay through Google Pay with credentials stored in Google Wallet. Your finance team needs to know where the transaction occurs, who handles disputes and returns, and what the PSP integration requires. Google states you need a Google Pay and Wallet Console account, and direct processors must upload PCI compliance documentation.
3. Customer data you will and will not receive (owner: CRM and analytics)
This is the question most teams skip. When checkout happens on a platform’s surface, what first-party data do you get back? Google says Business Agent will eventually offer new customer insights, but the details are still forward-looking. Amazon’s assistant has account memory, meaning it personalizes answers from each customer’s shopping activity, and that memory belongs to Amazon. Get the data return in writing before you route volume through any agent. Our guide to clean identity data explains why the matching layer matters.
4. Content and crawler permissions (owner: SEO and brand)
Opting out of AI access protects content. It can also remove you from the answer. The tradeoffs of one control are laid out in our look at how a Google-Extended opt-out can cost Gemini visibility. Decide deliberately, by agent, and document the reasoning.
5. Creator and claims content (owner: influencer and compliance)
- Inventory which creator posts and reviews carry specific product claims.
- Confirm disclosure is intact, because an agent summarizing a sponsored review can strip the context.
- Align creator briefs with the attributes in your feed so the agent hears one story.
Where Amazon’s agent gets blunt: Buy for Me
This one deserves its own flag. According to Amazon’s announcement, a branded search in Rufus surfaces products on Amazon and also from other merchants. The shopper sees either a “Buy for Me” button, where Amazon agentically purchases on their behalf, or a “Shop Direct” button that sends them to the merchant’s site.
Think about what that means. Your direct-to-consumer site could be the fallback, not the default. Ask your Amazon team which of your products appear in the Buy for Me flow, and what the customer experience is when the purchase happens off your site. If you run creator codes or affiliate links, test whether they survive an agent-completed purchase. They may not. Pilot it before you attribute any sales.
What should we measure?
Standard last-click reporting will mislead you. An agent can compare, shortlist and buy without a single session on your site.
- Agent-surface share of orders. Tag every order by origin (AI Mode, Gemini, Alexa for Shopping, and later Instagram).
- Holdout tests. Keep a matched set of products or regions out of agent checkout, then compare incremental revenue. The logic is the same one we recommend in our guide to holdout tests before scaling.
- Return and dispute rates by surface. Agent-driven orders may carry different return behavior. Do not assume.
- Brand accuracy audits. Ask each agent about your products monthly and log wrong claims, wrong prices and missing variants.
Amazon’s own numbers show why this matters. Amazon says in the same announcement that monthly average users of its assistant are up 149% and interactions up 210% over the past year. Those are Amazon’s claims, not independent measurements, but the direction is clear enough to justify setting up measurement now.
Governance: who can approve what?
Agents act. That changes the risk profile. A wrong feed attribute used to mean a bad listing. Now it can mean a wrong purchase completed automatically.
Set approval tiers. Low-risk changes (adding an image, fixing a title) can move through a fast path. Anything touching price, availability, claims or checkout eligibility needs a named approver. Our risk-tiered approval model shows one way to structure this. Also set a rollback rule: who can pull a product out of agentic checkout in an hour, not a week?
The brands that handle agentic commerce well will not be the ones with the best agent. They will be the ones that can answer, in one meeting, who owns the feed, the claims, the data return and the kill switch.
What to do this quarter
Start with the cheapest, highest-leverage work: clean the feed, confirm checkout flags, and ask each platform in writing what customer data returns to you. Then run one small pilot in a single product category on one agent, with a holdout, and review the results before widening.
FAQs
What is the Universal Commerce Protocol?
It is an open standard Google launched for agentic commerce. It standardizes how AI agents and merchant systems exchange information across discovery, checkout and post-purchase support, and it works with the A2A, AP2 and MCP protocols. Google’s help documentation says it powers a checkout button on eligible listings in AI Mode and Gemini.
Do I stay the seller if an agent completes the purchase?
On Google’s UCP-powered checkout, yes. Google’s help page says you remain the seller of record even when checkout happens on Google’s surfaces. Check the terms for returns, disputes and data sharing with your legal team before you opt in.
Is Meta’s AI shopping agent live?
Not as a confirmed product. Digital Trends reports Meta is building an Instagram shopping assistant planned for late 2026, and that a separate project called Hatch is in testing. Treat those details as reports until Meta announces them.
What does Amazon’s Buy for Me button do?
According to Amazon, it lets Amazon agentically purchase an item on the shopper’s behalf. The alternative, Shop Direct, sends the shopper to the merchant’s own website. Ask your Amazon contacts how your products are treated in each flow.
How do I measure the impact of AI shopping agents?
Tag orders by agent surface, run holdout tests on matched products or regions, and compare returns and disputes by channel. Last-click attribution will undercount agent influence because the agent can shortlist and buy without a site visit.
Who inside the company should own this?
Assign owners by workstream: ecommerce for feeds, finance and legal for payments and seller terms, analytics for data return, and influencer and compliance teams for creator claims. A single executive sponsor should resolve conflicts between them.
Next step: this week, pull your top 20 products and check each one’s feed attributes, price consistency and checkout eligibility across Google Merchant Center and Amazon. Then name one owner for each checklist item above.
