Merchant Center Loyalty Program Expansion: AI Mode, 14 Countries and the Customer Match Requirement

What Google Expanded

Google's Help Center now describes an expanded set of loyalty program features in Merchant Center. Per its documentation, loyalty annotations are available for local inventory ads and regional Shopping ads; the features have expanded to 14 countries (Australia, Brazil, Canada, France, Germany, India, Italy, Japan, Mexico, the Netherlands, South Korea, Spain, the United Kingdom and the United States); and loyalty benefits can be shown on Google's AI-first surfaces such as AI Mode and Gemini. Industry coverage on October 2, 2026 highlighted the AI Mode piece, and the loyalty help page notes that AI Mode and Gemini display is US only.

If you already run a points, membership or VIP program, this is a rare feature that can raise conversion without extra media spend. It is also one that has real compliance exposure, because it puts price and shipping claims in front of shoppers based on who they are.

What You Can Show

Google's documentation lists a range of benefit types merchants can submit, including free delivery, redeemable points and member pricing.

• Member pricing: submit tier-specific pricing using the loyalty_program attribute.
• Member shipping: set shipping policies per tier. If only certain products qualify, use the shipping label inside the loyalty program attribute.
• Points: redeemable points can be submitted as a benefit.
• Local and regional: annotations now work on local inventory ads and regional Shopping ads, so in-store perks can be promoted.

When a shopper who is a loyalty member is signed in to their Google Account, Google can show the perks available to them automatically. Everyone else sees the standard offer.

The Requirement Merchants Miss: Customer Match

Here is the detail that surprises people. Per Google's documentation, to show member shipping benefits and green strikethrough pricing for known members, you must set up Customer Match lists in Google Ads. Google identifies loyalty members through methods including Customer Match, where you upload a member list for each loyalty tier in Audience Manager. The tiers must match the labels you used in Merchant Center. For example, if bronze is tier 1 in Merchant Center, the Customer Match list should be set to loyalty members tier 1.

Google's loyalty documentation also notes a pilot for US merchants to use Customer Match as a relationship data source for free listings, available by contacting support. Treat that as a limited program, not a general capability.

Setup Walkthrough

1. Confirm eligibility. You need an existing loyalty program and to be selling in a supported country.
2. Enable the loyalty add-on in Merchant Center and define your tiers and labels.
3. Add loyalty_program data to your feed: tier labels, member pricing and shipping label where relevant. Product-level shipping loyalty sub-attributes (loyalty_program_label and loyalty_tier_label) were also added in the 2026 spec update, covered in our spec changes timeline.
4. Build Customer Match lists per tier in Google Ads and align their tier labels exactly with Merchant Center.
5. Test by signing in with a member account where possible and checking the annotation.
6. Monitor Diagnostics for errors and check that benefits shown match what the member actually receives.

Compliance Traps With Member Pricing

Showing a lower price to some shoppers than others is legitimate when it is truly a member benefit, but a few things can turn it into a violation.

• Member price must be real at checkout. If a signed-in member sees $80 in the ad but $95 at checkout because the account was not recognized, that is a price mismatch. See price accuracy violations.
• Joining must be genuinely open and clearly described. If the program is free to join, say so. If there is a fee, disclose it prominently. If it renews automatically, subscription disclosure rules may apply; see FTC negative option compliance.
• Tier benefits must match the feed. Do not advertise free shipping for the gold tier if gold only gets it above a threshold.
• Do not hide the base price. The standard non-member price must remain accurate and visible.
• Points are not discounts. If you advertise points, make the earning and redemption rules clear.

Our loyalty compliance guide goes deeper on each of these.

Regional and Local Considerations

Expansion to 14 countries brings local rules. Price display, consumer rights and data protection differ across these markets. In the EU and UK, member data handling falls under GDPR and UK GDPR; advertising price claims are governed by national consumer law. Verify each market before turning the feature on, and keep feeds separate where benefits differ by country. Our guide to multi-channel feed management helps with maintaining market-specific data.

The AI Mode Angle

AI Mode and Gemini display of loyalty benefits is the headline, but note two limits from Google's own documentation: it is US only for now, and Google has not committed to a date for the other markets. Do not build a business case on a feature that is not available where you sell.

What you can do is prepare. AI surfaces draw on product data, so complete loyalty data, accurate attributes and clean policies position you for when your market is enabled.

Loyalty Readiness Checklist

Measuring Whether Loyalty Annotations Pay Off

Loyalty features cost nothing in extra fees according to Google, but they cost effort, so measure the return. Establish a baseline before launch: conversion rate and average order value for known members versus other customers, and click-through rate on your Shopping listings for the products you will enable first.

After launch, compare the same metrics over equal periods, accounting for seasonality. Because Google shows member perks only to identified members, the effect shows up mostly among returning customers, so look at repeat purchase rate and the share of orders from members rather than only top-line conversion. If you cannot separate these in your analytics, tag member orders at checkout so you can.

Also watch the downside signals: customer service tickets about prices that differ from what was shown, abandoned carts at the login step, and any rise in price mismatch warnings in Diagnostics. A benefit that confuses shoppers can hurt more than it helps. If you see friction, simplify: fewer tiers, clearer labels, and a login prompt that appears before the cart rather than at the final step.

Start with one or two tiers and a limited set of best-selling products. Expanding gradually keeps the data clean and limits the blast radius of any configuration mistake.

Five Mistakes That Delay Approval or Cause Warnings

• Tier names in Merchant Center that differ by even a character from Customer Match list labels
• Member prices shown in the feed that require a sign-in step the shopper cannot easily find
• Uploading customer lists without a documented consent basis
• Enabling every country at once instead of starting with your largest market
• Forgetting to update benefits in Merchant Center when the program changes on the website
