Why did Google split my Shopping variants?
Direct answerGive every variant of one product the same item group ID, and give each variant its own product ID. Google’s item group ID attribute, reviewed October 28, 2026, is required for variants on free listings, and for Shopping ads in Brazil, France, Germany, Japan, the United Kingdom, and the United States.
What Google treats as one product
A variant differs by details such as color and size, or, for electronics, memory, display size, processor, or graphics. Submit each variant as its own product. Use one item group ID across that set, and a different item group ID for a different product. The landing page has to match the group: if the page lets a shopper pick the size and color, those rows share an item group ID.
Google says a product that misses these requirements is disapproved, and the notice is in Diagnostics:
- Each different product gets its own group ID. Do not recycle an ID.
- Do not use letter case as the only difference.
- Submit an item group title with the ID, and use that same title on every variant in the group.
- Submit the variant option attribute with the title and the ID, naming the properties that differ, such as color and size, or memory and display size.
- Also submit the standard color, pattern, material, age group, gender, and size attributes when those are the differences. The allowed color and size formats are on the apparel attributes page.
- The landing page has to show the same variant details you submit, including title, variant option, color, price, availability, and image.
What not to group
Google’s best practices: use the parent SKU as the item group ID, and do not submit that parent SKU as its own product. Do not submit an item group ID for a product that is merely similar. A suit of a jacket and pants, and a set of bath accessories, are the examples of products that are not variants. Keep the ID stable after you assign it. Give each variant a different landing-page URL, with a different path or query, such as /t-shirt/green or /t-shirt?color=green&size=small. The product URL rules are the link attribute.
This attribute page does not print a 7-day suspension warning.

Frequently asked questions
I have three colors and three sizes. How many products is that?
Nine. Google’s example is a T-shirt in three sizes and three colors, submitted as nine products, each with its own ID and the same item group ID. A jacket and pants sold as a suit, or a set of bath accessories, is not a variant group. Google’s best practice is not to give those an item group ID.
Can I change the item group ID after the products are live?
Google’s best practice is not to. Once a group has an ID, keep it. Changing it often can make the variants group inconsistently. Also do not reuse an old item group ID on a different product, and do not rely on capital letters to make two IDs different.
Does the parent SKU get its own row?
No. Google’s best practice is to use the parent SKU as the item group ID on every variant, and not to submit the parent SKU as a separate product.
Check that each variant matches its page
LaunchGuarding can scan the landing page for a color or price the variant row is about to contradict.
