Google Merchant Center product feed: required fields and setup

A product feed is the structured connection between your store catalog and Google Merchant Center. The goal is not simply to upload a file. It is to keep every listing aligned with the product page a shopper will open. A polished Shopping campaign cannot compensate for stale prices, missing identifiers or incorrect variants.

Pick the source of truth

Use your ecommerce platform or product information system as the source for price, stock and variant data. Choose an integration, scheduled file or API based on how often these values change. Google also offers automatic product discovery on eligible sites, but you should still compare the extracted data with your catalog. Read Google’s product-source options before choosing a method.

Map the essential attributes

Google’s product data specification is the reference for required and conditional attributes. Start by checking:

id: stable, unique and unchanged across refreshes for the same product or variant;
title and description: identify the product accurately, using language a customer understands;
link and image_link: lead to the correct public page and a clear product image;
price and availability: match the landing page and checkout;
brand and identifiers: submit valid brand, GTIN or MPN data where applicable;
condition and shipping attributes: provide them where your category or market requires them.

Do not invent a GTIN to fill a field. If a product genuinely has no identifier, follow the specification for that case. For sizes and colors, submit each sellable variant consistently and point its link to the matching selection.

Add useful information without stuffing

An informative title helps Google and customers understand the product. A useful pattern is brand + product type + defining attribute + variant, where those details are relevant. Keep promotional slogans out of the product title. Use accurate categories, product types and custom labels to organize your catalog for reporting and bids, not to hide weak product data.

Validate before scaling

Test a small set of representative products: an in-stock item, an out-of-stock item, a discounted item and a variant. Compare the feed, the visible product page and any Product structured data. Then check Merchant Center’s product statuses after processing. Keep a change log for feed rules so you can trace why a price or title changed.

Ongoing checklist

A single system owns each mutable attribute.
Updates run often enough for your stock and pricing cadence.
Discounts include the correct regular and sale prices.
Variants have distinct IDs and correct destination URLs.
Merchant Center warnings are reviewed after every major catalog change.

Next, configure shipping and returns and resolve rejected products. For a complete setup, start with the Merchant Center guide or ask about our Google Shopping service.
