Google Merchant Center setup and fixing disapprovals

How do you set up Google Merchant Center?

Google Merchant Center setup has four steps: create the account and enter business details, verify and claim your website, configure shipping and return settings, and upload your product data. Once done, your products can appear in Google's free listings and, after linking Google Ads, in Shopping and Performance Max ads.

The setup itself is usually quick; what takes time is clearing product disapprovals and policy warnings. This guide covers both the setup steps and fixes for the most common disapprovals.

What should your site have before you start?

Merchant Center expects your site to offer a trustworthy shopping experience. Given Google's Shopping policies and misrepresentation rules, check these before setup:

• Contact details: A real address, phone or email, and an easy-to-find contact page.
• Return and exchange policy: Clear, on its own page and accessible before checkout.
• Shipping information: Costs and delivery times.
• Secure checkout: Pages that collect payment and personal data protected with SSL.
• Accurate product information: Price, stock, product details and promotion terms stated clearly on the page.

What are the Merchant Center setup steps?

1. Create an account. Sign in to Merchant Center with your Google account and enter your business name, country and where you sell.
2. Complete business information. Add your address and customer service contact details.
3. Verify and claim your website. Google asks you to confirm that you own your store URL. You can use the Google tag, an HTML tag, an HTML file, or Google Analytics or Google Tag Manager. Google apps on platforms such as Shopify usually handle this automatically.
4. Configure shipping. Define delivery regions, costs and delivery times.
5. Add your return policy. Enter the return window, conditions and a link to your return policy page.
6. Upload product data. Use a platform integration, Google Sheets, a scheduled feed file or the API.
7. Link Google Ads. Connect Merchant Center and Google Ads for Shopping and Performance Max campaigns.

Which product data fields are required?

Google's product data specification makes certain attributes mandatory for every product. The core ones are id, title, description, link, image_link, availability, price, brand and, for eligible products, GTIN. Categories such as apparel may also require color, size, gender and age group.

Filling these correctly matters for performance as well as approval. For optimizing fields such as title and product type, see our Performance Max product feed guide.

Which method should you use to upload product data?

There are several ways to send product data to Merchant Center, and the right choice depends on catalog size and how often prices and stock change:

• Platform integration: Google apps for Shopify, WooCommerce and similar platforms sync products automatically. Easiest to set up, but control over fields such as titles and custom labels can be limited.
• Scheduled feed file: Merchant Center fetches an XML or CSV file generated by your site at set intervals.
• Google Sheets: Practical for a small catalog, but manual updates make it error-prone when prices change often.
• API: The most flexible option for large stores with thousands of products and frequent price changes; it needs development resources.

Whatever the method, supplemental data sources and attribute rules let you enrich titles, product types and custom labels without touching the primary source, which is especially useful when you cannot change your platform's feed output.

The most common disapprovals and how to fix them

The Merchant Center diagnostics view shows which product was disapproved, why, and whether the issue is at item or account level. The cases we see most often in online stores:

Issue	Cause	Fix
Price mismatch	Feed price differs from the price on the page	Update the feed more often, reflect sale prices in the feed, align currency and tax display
Availability mismatch	Feed says "in stock" while the page shows "sold out"	Sync stock more often and update sold-out products in the feed
Missing or invalid GTIN	Barcode wrong, missing or made up	Enter the manufacturer's GTIN; use brand and MPN for products without one
Image issue	Watermark, promotional text, logo overlay, placeholder or low resolution	Use a clear product image without text or logos
Landing page not working	404 error, redirect or Google cannot access the page	Fix links and make sure the page is accessible to Google's crawlers
Missing shipping information	No shipping defined in the account or feed	Complete shipping settings in Merchant Center
Misrepresentation	Missing trust signals or misleading claims on the site	Clarify contact, returns and payment details, remove misleading claims, request review
Policy violation	Restricted or prohibited product category	Check Shopping policies and remove ineligible products from the feed

Why is misrepresentation so critical?

The misrepresentation policy is Google's rule against businesses that mislead users or hide relevant information. Unlike item-level errors, it can suspend the entire account. Google's help page lists hiding payment terms, return information or business identity, unrealistic offers and misleading claims among the behaviors it covers.

If you receive a misrepresentation warning:

• Add contact and return information reachable from every page of your site.
• Show all charges, including shipping, clearly at checkout.
• Remove unverifiable claims such as "cheapest" or "guaranteed results".
• Clean up empty "under construction" pages and broken links.
• Request a review in Merchant Center only after all fixes are complete.

Requesting reviews repeatedly without fixing the problem can drag the process out. Audit the whole site first.

What routine prevents disapprovals?

• Check the diagnostics view at least once a week.
• Set feed update frequency to match how often your prices and stock change, and increase it during promotions.
• Make price changes on the site and in the feed at the same time.
• Use a checklist of required fields and image rules when adding new products.
• Recheck product links and verification after site redesigns or platform changes.

Key takeaways

• Before setup, make contact, returns, shipping and secure checkout information clear on your site.
• Verify and claim your website, and complete shipping and return settings in Merchant Center.
• Fill required product data fields completely and accurately.
• Price and availability mismatches, GTINs, images and landing page errors are the most common disapproval causes.
• Misrepresentation works at account level; fix the whole site before requesting a review.
