In short. Google Merchant Center accepts and manages product data that Google uses for eligible free listings and paid advertising.

Definition: As of 17 October 2026, Google Merchant Center is Google's free tool for submitting and managing product data for shopping surfaces across Google. It accepts product information from store connections, files, spreadsheets and other supported sources so eligible products can appear in free listings or paid advertising.

Key facts

Google's Merchant Center overview describes a free account for retailers selling through a website, a physical store or both.
Google's upload guide supports ecommerce platform connections, files, Google Sheets, automatic collection from an online store and the Merchant API, an interface for applications to manage Merchant Center data.
Google's free listings documentation includes Gemini among the places eligible products can appear at no cost.
Google's data source guide distinguishes primary sources, which can add or remove products, from supplemental sources, which update existing product details.

How is product data submitted?

A data source supplies product information to Merchant Center. Google's data source guide defines a primary source as the main source used to access and display product data. Its setup includes target countries, language and marketing methods, which determine which Google features can use the submitted products.

Google's upload guide explains that a file contains product details mapped to named attributes. A file can be uploaded from a computer or hosted at a URL for Google to retrieve. Google Sheets provides a spreadsheet template, while the Merchant API supports frequent changes or large uploads.

A connected ecommerce platform supplies store information directly; Google recommends managing those products through the platform. Automatic collection from a website uses schema.org structured data, machine-readable product information embedded in web pages, and permission for Google to collect it. The same guide states that this automatic collection method is incompatible with local inventory ads and free local listings.

Which product details must match the website?

Google's Product data specification defines the attributes used in submissions. The following are attribute names used in product data files, rather than a complete submission template:

id
title
link
image_link
price
availability

The id identifies a product and stays the same when its data is updated. The link points to the product's landing page on the verified domain, and image_link supplies the main product image URL.

The same specification requires the submitted price and currency to match the landing page, structured data and checkout. Availability must also agree across the submission, landing page, checkout and structured data. Supported availability values include in_stock, out_of_stock, preorder and backorder.

Where can products appear, and how are issues checked?

Google's free listings documentation names Search, Maps, Gemini, YouTube, the Shopping tab, Images and Lens as supported surfaces. It also names the products module on Business Profile. The Free listings setting controls permission to show products; actual display depends on Google's matching of product data to shoppers' searches.

The same documentation requires compliance with free listing policies and describes shipping settings and return policy information. Google's official overview also describes supplementing free listings with paid advertising through Google Ads.

For operational checks, Google's product management guide identifies the Products page for visibility and approval statuses. Its Needs attention tab lists issues involving policies or missing or inaccurate product details. Updates to products supplied by a file or spreadsheet are made in their original source.
