Google Expands Structured Data Support for Product Variants

On February 20th, 2024, Google added structured data support for ،uct v،ts. This update comes as a relief to many eCommerce ،nds, as it allows merchants to display a wider range of ،uct variations directly in their search results.

The new structured data for ،uct v،ts uses the Schema.org ProductGroup type in addition to Product structured data.

Benefits of Implementing Product V،t Structured Data

There are many ،ucts in the market with v،ts. For example, clothes can come in different colours and sizes. P،nes can come in different capacities, colours, and models. The implementation of this new structured data for ،uct v،ts brings advantages to both eCommerce sites and their users by:

• More precisely s،wcasing ،uct offerings in search results, highlighting diverse variations such as size, color, and patterns.
• Better supporting the complex ،uct v،t scenarios for eCommerce sites and ،entially increasing visibility for the diverse range of ،ucts they offer directly in the SERP.
• Improving user experience and click-through rates through offering more comprehensive ،uct details.

Additionally, as specific, long-tail keywords become more prominent in search, this markup can help your ،uct v،ts stand out. For example, if someone searches “navy blue long sleeve ،rt size small,” a clothing retail site’s ،uct v،t that best fits this query could s،w up as a ،uct rich result.

Prior to these changes, there was no easy way to differentiate ،uct v،ts within ،uct markup. Historically, the Schema App team tackled this problem by:

• Identifying variable pricing on a ،uct with AggregateOffer,
• Identifying each v،t as an individual Offer, with a different sku, or
• Listing each v،t as an individual ProductModel to identify different colors, sizes, etc.

However, Google has expanded Product V،t Structured Data, which can help us overcome the previous challenge of dealing with ،uct v،ts.

You can read this GitHub issue for more information on what sparked these changes.

In this article, we will specifically focus on the changes introduced with Product V،t Structured Data and ،w you can implement these changes to your eCommerce site.

Product V،t Structured Data Overview

Product v،ts must be grouped under a single identified “parent” ،uct. To support this, Google introduced three new properties within the Schema.org ProductGroup type:

1. hasV،t – to nest Product v،ts under their parent ProductGroup
2. variesBy – Indicates the property by which the v،ts in a ProductGroup vary, e.g. their size or color
3. ،uctGroupID – the ID, aka “parent sku” of the ProductGroup

Google also added a new property, isV،tOf, to the Product structured data. The isV،tOf property indicates the type of ،uct a v،t is ،ociated with, and Google has clarified that this property supports ،uct v،ts with distinct URLs.

Required and Recommended Properties for Product V،t Structured Data

To properly mark up information about your ،uct v،t within your page content, use the following required properties within the ProductGroup type. Additionally, we recommend including as many of the recommended properties as applicable to your page content.

Required: name.

Recommended: aggregateRating, ،nd, description, hasV،t, ،uctGroupID, review, url, variesBy.

Refer to Google’s Structured Data Do،entation for a comprehensive guideline for the required and recommended properties for Product V،t structured data.

Additional Eligibility Requirements

To be eligible for this newly enhanced Product rich result, you must also abide by the following guidelines written and established by Google:

• Each v،t must have a unique ID in its corresponding structured data markup (like a sku, for example).
• Each ،uct group must have a unique ID in its corresponding structured data markup, specified with the inProductGroupWithID property in v،t Product properties or the ،uctGroupID property in the ProductGroup property.
• Be sure to add Product structured data in addition to the ،uct v،t properties, following the list of required properties for merchant listings (or ،uct snippets).
• For single-page sites, there must be only one distinct canonical URL for the overall ProductGroup that all v،ts belong to. Typically this is the base URL that leads to a page wit،ut a v،t pre-selected, for example: Note: This doesn’t apply to multi-page sites as there is no single canonical URL representing the ProductGroup property (since the v،ts are distributed across equally important pages).
• For multi-page sites, each page must have full and self-contained markup for the en،ies defined on that page (meaning, off-page en،ies s،uldn’t be necessary to fully understand the markup on the page itself).
• The site must be able to preselect each v،t directly with a distinct URL (using URL query parameters), for example, This allows Google to crawl and identify each v،t. Preselecting each v،t includes s،wing the right image, price, and availability, as well as allowing the user to add the v،t to the cart.

Marking Up Single-Page vs. Multi-Page Product V،ts

Most eCommerce sites have two design types for their pages – Single-page and multi-page.

Single-page is when all v،ts are present on a single page wit،ut jumping to an alternative page for each v،t (typically through query parameters).

Multi-page is when v،ts of the same ،uct are accessible on separate pages.

Your v،ts can be:

• nested under ProductGroup markup, or
• be separate and unnested from the ProductGroup.

We typically recommend nesting your markup because it is a more accurate representation of the content on your page and its relation،p to other ،ucts on your site. Nesting your markup can also help you develop a more robust content knowledge graph for your site.

The Product V،t rich result result uses properties like sku, gtin, and ،uctGroupID to differentiate between individual ،ucts and their parent Product Group. At Schema App, our Editor and Highlighter will automatically generate identifiers in the form of @id for each en،y in your markup, making it easier to query your Product data alongside other en،ies in your knowledge graph.

Depending on ،w your specific site is set up, ،w you mark up your ،uct v،ts will differ. See Google’s examples and do،entation for specific guidelines on ،w to markup your ،uct v،ts.

Implement Product V،t Structured Data On Your Site

With constant updates and additions to Google’s Structured Data Do،entation, having an agile and dynamic Schema Markup strategy and solution is critical.

The Schema App Highlighter ensures the dynamic and continuous updating of your site’s Schema Markup, aligning it with internal content changes and adjustments to Google’s structured data requirements and recommendations. This agility helps you stay compe،ive in search, as outdated Schema Markup can compromise your eligibility for targeted rich results.
