How to set up Google Merchant Center for Shopping ads
This guide walks you through creating a Google Merchant Center account, getting your products in, setting shipping and returns, and linking it to Google Ads so your products can run in Shopping campaigns.
Google Merchant Center is where your product data lives for Google. Shopping ads and Performance Max campaigns that show products pull titles, prices, images, and availability from it, not from your ad account.
Setup has four parts: the account and your business details, your products, your shipping and return policies, and the link to Google Ads. Google then reviews your products and website before they can serve, so build in a few days before you plan to launch.
Create your Merchant Center account
Go to merchants.google.com and select Create an account. Enter your business name and where you sell: online, in a physical store, or both. Your business address sets your country and time zone, and Google states the country cannot be changed later. One Google Account email can only create one Merchant Center account, so use the login your business will keep.
Verify and claim your website
Select Settings, then Business info, then Edit online store, and enter your full URL starting with https://. Google offers several verification methods, including an email code, your ecommerce platform, an HTML tag or file, Google Tag Manager, or Google Analytics. Claiming ties the URL to your account, and a URL can be claimed by only one Merchant Center account.
TipGoogle notes that the Google Analytics method may not work for stores on third-party platforms such as Shopify, and suggests an HTML tag instead.
Connect Shopify with the Google & YouTube app
In your Shopify admin, install the Google & YouTube app and select Connect Google Account, using the email that manages Merchant Center. Choose your existing Merchant Center account and select Connect, or select Create new. The app checks your store details, verifies your business phone number, and asks for target country, language, and shipping settings before you select Complete setup.
Watch outBefore connecting, remove your store password and add a refund policy, terms of service, and contact details. The app requires them.
Add products if you are not on Shopify
Open Products under Products & store and select Add Products. You can connect another supported ecommerce platform, upload a product file, or add items one at a time. Google says an initial platform import can take up to 3 days. Every product needs an id, title, description, link, image link, availability, and price.
Fill in brand and product identifiers
Brand is required for new products, with exceptions for movies, books, and music. A GTIN, such as a UPC barcode, is strongly recommended when the product has one. If there is no manufacturer GTIN, submit an MPN instead. If a product has none of the identifiers its category calls for, set identifier_exists to no. Condition is required for used or refurbished items.
Set up shipping
Go to Shipping and returns under Products & store, open Shipping policies, and select Add shipping policy. Choose the countries you ship to, which products it covers, your order cutoff time, handling time, transit time, and a cost option that matches how your store charges. Use the same currency as your product prices. Google warns products may be disapproved if no shipping service matches their currency.
Add your return policy
On the Return policies tab, select Add return policy. Enter the URL of your return policy page, the countries it covers, whether you accept returns and exchanges, the return window, return methods, any restocking fee, and refund processing time, then select Save. Google lists this as optional in Merchant Center, but your website must still show clear return and refund information.
Link Merchant Center to Google Ads
In Merchant Center, open Settings, then Access and services, then Apps and services, and select Add service. Choose Google Ads, select Next, pick the account, select Next, then Link. If you are an admin of both accounts, the link is approved automatically. Otherwise a Google Ads admin approves it under Tools, Data manager, Connected products, then Manage & link.
Fix issues and wait for review
Open Products and select the Needs attention tab to see disapproved products and warnings. Account-level problems appear as a banner or under View setup and policy issues. Google says the first Shopping ads review takes about 3 to 5 business days, with products showing as Pending. After fixing an issue, request a review. Account-level reviews can take up to 7 days.

The most common problems with self-built Google Ads setups, and what they cost.
Prices that don't match the website
If the price in your product data differs from the landing page, Google flags a price mismatch and can disapprove the product. Sale prices, structured data errors, and prices loaded late by JavaScript are common causes.
Missing policy and contact pages
Google's misrepresentation policy expects genuine business and contact details, clear pricing, and return terms you honor. Thin or missing policy pages can lead to account-level problems that affect every product.
Letting automatically found products into campaigns
Google can add products it finds on your site through structured data. Google notes that campaigns may then include additional products, so review which products your campaigns can show.
Running two sources for the same products
Connecting Shopify and also uploading a separate file creates confusion over which data is current. Pick one main source and manage changes there.
Skipping identifiers
Leaving out brand, GTIN, or MPN where they apply can cause disapprovals or limited performance. Fill them in from your supplier or product packaging.
What this guide doesn't cover
An approved feed gets your products eligible to show. What decides whether Shopping makes money is the feed work after it: titles that match how people search, product groups split by margin, supplemental data, and campaign structures that keep low-margin items from absorbing the budget.
ADM manages Google Shopping and Performance Max for established eCommerce brands, with feed optimization and bidding set against contribution margin rather than platform ROAS alone.

Common questions
How long does Merchant Center take to approve products?
Google says platform imports can take up to 3 days to appear, and the initial Shopping ads review takes about 3 to 5 business days.
Do I need GTINs for Google Shopping?
Not always. Google strongly recommends a GTIN when the product has one. Without a manufacturer GTIN you submit an MPN, and brand is required for most new products.
Can one Merchant Center account link to several Google Ads accounts?
Yes. Google allows up to 500 linked Google Ads accounts, but a Google Ads manager account itself cannot be linked.
Why can't I link Merchant Center to Google Ads?
You need admin access in Merchant Center to send the request and admin access in Google Ads to approve it, and neither account can have account-level policy violations.
