GMC Missing Color, Gender and Age Group: Apparel Fix Guide

Short answer

Google Merchant Center flags missing color, gender and age group when apparel products are submitted without these attributes. They are required for clothing and accessories shown in several countries, including the US and UK, and clothing and shoes also need a size. Fix it by adding color, gender and age_group to every apparel product and variant in your feed, using Google’s accepted values, and make sure they match what the product page shows.

Clothing stores see more product data errors in Google Merchant Center than almost any other category, and missing color, gender and age group are among the most common. The product looks complete on the website, but the feed does not send these attributes, so Google cannot tell who the item is for or which variant it is. This guide explains when apparel attributes are required, which values Google accepts, and how to fix missing fields before review, based on 5+ years of Merchant Center work.

What the missing apparel attributes error means

Google groups clothing, shoes, jewellery, bags and similar items as apparel and accessories. For these products, Google uses color, gender and age_group to show the right variant to the right shopper and to power the filters on Google Shopping. When one or more of these values is missing, Merchant Center shows an issue such as “Missing value [color]”, “Missing value [gender]” or “Missing value [age_group]”, and the product is disapproved or limited.

When Google requires these attributes

Attribute	Required for	Accepted values
color	Apparel and accessories in countries such as the US, UK, Germany, France, Japan and Brazil	The color name, or up to 3 colors separated by /
gender	Apparel and accessories in the same countries	male, female, unisex
age_group	Apparel and accessories in the same countries	newborn, infant, toddler, kids, adult
size	Clothing and shoes in the same countries	The size shown on the product, such as M, 10 or 32×34
item_group_id	All products that have variants	A shared ID for all variants of one product

Even where these attributes are not strictly required, adding them helps Google match your products to the right searches and filters.

How Google checks apparel data

Feed values: each attribute must use an accepted value and format.
Product page: the color, size and target shopper should match what the landing page shows.
Variants: each variant needs its own color and size, and all variants need the same item_group_id.
Images: the image for each variant should show that variant’s color.

Common causes of missing color, gender and age group

Cause	What happens
Feed app does not map gender and age group	Google receives empty values for every product
Color stored only in the title or description	The color attribute is empty
Variant options named differently, such as Colour or Shade	The feed does not recognise them as color
Invalid values like Men, Ladies, Baby or Teen	Google treats them as missing or invalid
Products imported from suppliers without attributes	Whole collections are flagged at once
Supplemental feed or rules overwriting values	Correct values are replaced with empty ones

How to fix missing apparel attributes, step by step

Open the issue in Merchant Center. Note which attributes are missing and how many products are affected.
Check your feed mapping. Confirm which store fields your feed app sends as color, gender, age_group and size.
Add gender and age group. Set them in your feed app or with product metafields, using only male, female or unisex, and newborn, infant, toddler, kids or adult.
Set color and size per variant. Use clear variant option names such as Color and Size so the feed picks them up.
Fix invalid values. Replace numbers, hex codes, abbreviations and phrases like see image with real color names.
Check item_group_id. Make sure all variants of one product share the same ID.
Match the product page. Show the same color, size and target shopper on the landing page.
Update the feed. Let Google reprocess the products, or request a review where Merchant Center offers one.

A quick apparel attributes checklist

Every apparel product has color, gender and age_group
Clothing and shoes also have size
Gender uses male, female or unisex only
Age group uses newborn, infant, toddler, kids or adult only
Multi-color items list up to 3 colors separated by /
Each variant has its own color and size
All variants share one item_group_id
Variant images show the correct color

What not to do

Do not set every product to unisex or adult just to clear the error if that is not accurate.
Do not use made-up color names that shoppers will not recognise without also using a standard color.
Do not put several colors into one word, such as BlackWhite.
Do not fix values only in Merchant Center while your store still sends empty values.
Do not submit variants as one product with a list of colors and sizes.

Missing apparel attributes vs. missing GTIN

	Missing color, gender, age group	Missing GTIN
What is missing	Product details about the variant and shopper	The product’s barcode number
Who it affects	Apparel and accessories	Branded products with a manufacturer barcode
Usual impact	Disapproval or limited visibility	Limited performance or disapproval
Fix	Add the attributes in your feed	Add the real GTIN or set identifier_exists correctly

If your apparel products also show identifier issues, read our guides to missing GTIN and missing brand attribute problems.

Frequently asked questions

Why does Google Merchant Center say my product is missing color, gender and age group?

Google requires these attributes for apparel and accessories products in several countries. If your feed does not send them, or sends them in the wrong format, the products are disapproved or limited until you add them.

What values can I use for gender and age group?

For gender, use male, female or unisex. For age group, use newborn, infant, toddler, kids or adult. Other values, such as men, ladies, baby or teen, are not accepted.

How should I write the color attribute?

Use the color name a shopper would recognise, such as Navy or Black. For products with more than one color, list up to three colors separated by a slash, for example Black/White/Red. Do not use numbers, hex codes or phrases like see image.

Do variants need their own color and size?

Yes. Each variant is a separate product in Merchant Center, so each one needs its own color and size value, along with a shared item_group_id that links the variants together.

Why does Shopify not send color, gender and age group?

Shopify’s Google and YouTube app reads color and size from variant options, but gender and age group usually need to be set in the app or with product metafields. If they are missing there, Google receives empty values.
