Google Shopping feed specification

Google Shopping feed specifications define the technical and content requirements your product data must meet to be accepted, understood, and displayed correctly across Google Shopping, Google Ads, and emerging AI-driven shopping experiences powered by Google Merchant Center.

These specifications outline which attributes are required, how they must be formatted, and when they apply, ensuring Google can accurately interpret product information and match it to relevant shopping queries.

Google Shopping feed specifications are maintained and enforced through Google Merchant Center, and they are regularly updated to reflect new product types, markets, and commerce features.

Why are Google Shopping feed specifications important?

Complying with Google Shopping feed requirements is critical for:

• Product approval and eligibility
• Consistent visibility across Shopping ads and free listings
• Preventing account suspensions, disapprovals, and warnings

Even small formatting issues, such as incorrect price structure, missing identifiers, or invalid availability values, can cause products to be rejected or limited in reach.

Following Google Merchant Center feed specifications ensures your Google Shopping product data is complete, accurate, and aligned with Google’s automated and AI-driven product matching systems.

Required vs optional attributes in Google Shopping feeds

Google Shopping feed specifications clearly separate required and optional attributes.

Required attributes (for most products)

These must be present for a product to be eligible:

• id
• title
• description
• link
• image_link
• price
• availability
• brand
• gtin (or MPN where GTIN is not available)
• condition

Missing or incorrectly formatted required attributes typically result in product disapproval.

Optional but recommended attributes

While not always mandatory, these attributes significantly improve performance:

• googleproductcategory
• additionalimagelink
• sale_price
• shipping
• tax
• customlabel0–4
• color, size, gender, age_group (for apparel)

Using optional attributes correctly helps Google better classify products and improve ad relevance.

Attribute formatting rules and requirements

Google Shopping feed specifications include strict formatting rules to maintain consistency and accuracy.

Examples include:

• Price must include currency (e.g., 79.99 USD)
• Availability must match allowed values (instock, outof_stock, preorder)
• Titles have character limits and should avoid promotional text
• Image links must point to high-quality, non-watermarked images
• GTINs must follow global identifier standards

Failure to follow formatting rules is one of the most common causes of feed errors in Google Merchant Center.

Category-specific Google Shopping feed specifications

Some Google Shopping feed requirements vary by product category.

Examples:

• Apparel: requires attributes like size, color, gender, and age_group
• Electronics: stricter enforcement of GTIN and brand accuracy
• Books: ISBN used as GTIN
• Media and subscriptions: special pricing and availability rules

Assigning the correct Google product category (GPC) is essential, as it determines which category-specific specifications apply.

How often do Google Shopping feed specifications change?

Google regularly updates its Google Shopping feed requirements to support:

• New markets and currencies
• New product categories and attributes
• Policy updates and enforcement changes
• AI-driven discovery and shopping experiences

For example, in January 2026, Google announced updates tied to its broader shift toward AI-powered commerce, including changes connected to Universal Commerce Protocol (UCP) and AI-led Shopping experiences. These updates reinforced the need for more complete, structured, and consistently updated product data, as feeds increasingly power not just ads, but AI-driven product understanding and transactions.

Merchants are expected to keep feeds up to date with the latest specifications. Ignoring updates can lead to sudden disapproval or reduced visibility.
