Product data specification

This article details the requirements and format for every attribute accepted in Manufacturer Center. Some attributes are required, while others are recommended or optional. Failure to provide values for the required attributes will prevent that particular item from processing correctly in your feed upload. Failure to provide recommended or optional attributes will result in incomplete product data in our system, but will not cause the feed to fail.

Throughout this article, you will see the terms item and product. Please note that we use the term item to describe a single product variant. Items are similar to products, but we assume that products can occur in multiple variations. These variations, or “product variants”, can differ by color, size, or style. In other words, an item refers to a single variation of a product. Each entry in your product data file should reflect a single item, or product variant.

Keep in mind only attributes in English should be submitted in your feed, which you'll see in square brackets below. You'll see descriptive and/or translations of the values for illustrative purposes only.

Please note that if you provide many values for repeated attributes (i.e., feature description), we may only display the first few values.

Here are examples:

The values you provide may be displayed to users, so provide values that they will be able to understand.

Variant information

We define variants as a group of similar items that only differ by attributes like color [color] or style [style]. By submitting variant items, you will help Google improve the end user experience by grouping your products correctly on Google Shopping.

How to submit variant data

  • Begin by submitting an item for each variant.
    • For example, if you offer a particular model of mobile phone in 4 colors (black, white, silver, and red) and 3 storage capacities (8GB, 16GB, and 32GB), you need to submit 12 item variants (Black 8GB, Black 16GB, Black 32GB, White 8GB, White 16GB, etc.).
  • Include unique id[id] attribute values for each item variant, just like you would for all the other items in your product data.
  • To identify items as variants of one another, you need to group them together using an item group id [item_group_id]. Each item in the group should have the same item group id [item_group_id]. As a rule of thumb, if a user can choose to select different colors, patterns, sizes, styles, etc. on the landing page of your product, identify them as separate items, but identify them with the same item group id [item_group_id].
  • Include variant attributes in the title that indicate what makes each variant unique. A value for color [color] and/or product detail [product_detail] must be submitted to differentiate the items.

When crafting a title [title] for variant items, be sure to include the name common to all product variants, as well as the variant attributes that make the product unique.

Example:

  • Google Nexus 5 Android Phone - 32GB - Black - Unlocked - GSM
  • Google Nexus 5 Android Phone - 16GB - White - AT&T
item group id [item_group_id] - Identifies variants of a product/style
Attribute item group id [item_group_id] (see full guidelines)
When to include Optional; recommended for items with multiple variants
Type ASCII only
Character count Maximum 50
Repeated field No
TSV field example AB123-Sp14
XML example <g:item_group_id>AB123-Sp14</g:item_group_id>
Minimum requirements at a glance
  • Use a unique value for each group of variants. 
  • Use the parent SKU where possible 
  • Keep the value the same when updating your product data
  • Use only valid unicode characters
  • Use an item group id [item_group_id] for a set of products that differ by one or more of these attributes:
    • color [color]
    • size [size]
    • pattern [pattern]
    • material [material]
    • age group [age_group]
    • gender [gender]
  • If your products differ by design elements that aren't represented by the attributes above, don't use item group id [item_group_id]
  • Include the same attributes for each product in the item group. For example, if a product varies by size [size] and color [color], submit size and color for every product that share the same value for item group id [item_group_id]
