Product Detail [product_detail] Field for Product Feed

Optional for each product

The product_detail attribute lets you add structured, readable information about your product’s specifications or special features that aren’t already captured by other attributes.
This can help Google better match your product to relevant search queries and display detailed info in Shopping results.

When to use

• To describe technical specifications or extra details not covered by existing attributes.
• When you have multiple properties to highlight for a product (e.g., display resolution, battery life, materials).
• To improve structured product data and relevance in search.

Sub-attributes:

• section_name (Optional) – Category or grouping (e.g., “Display”, “Battery”).
• attribute_name (Required) – Name of the detail (e.g., “Resolution”).
• attribute_value (Required) – Value of the detail (e.g., “432 x 240”).

Format

• Type: String (Unicode; ASCII recommended)
• Structure (text feeds):
  section_name:attribute_name:attribute_value
  If there’s no section_name, start with a colon:
  :attribute_name:attribute_value
• Limits:
  • section_name: up to 140 characters
  • attribute_name: up to 140 characters
  • attribute_value: up to 1,000 characters
• Repeated field: Yes, up to 1,000 times

Formatting examples:

Minimum requirements

• Include exactly two colons in text feed format to separate the three sub-attributes.
• Only provide confirmed, accurate attribute values.
• Don’t duplicate information from other attributes (e.g., price, sale price).
• Avoid keywords, promotional text, or irrelevant information.

Improperly formatted or unverified details may lead to disapproval.

SEO Tip

Providing rich technical details helps Google better match your product to specific, long-tail searches. It also increases trust with customers by answering questions directly in the listing.
