Google Product Category is a key attribute for organizing products on platforms such as Google Shopping. It is a fundamental part of Google Product Taxonomy, a structured classification system that automatically assigns categories and subcategories to products in a shopping feed and online stores.
This attribute, known as "google_product_category", allows sellers to categorize their products in a precise way, which facilitates the search for users and improves the visibility of products on Google Shopping. Google's taxonomy consists of more than 6,000 categories, underscoring the importance of proper categorization to ensure better relevance and visibility.
The proper assignment of categories in Google Product Category helps users easily find the products they are looking for and enhances the online shopping experience. In addition, Google's product taxonomy is regularly updated to reflect changes in the marketplace and keep up with e-commerce trends and developments.
When it comes to categorizing the products in your stores, there are three ways you can take advantage of:
This methodology involves manually assigning Google Product Category categories to each product in your catalog. While it offers full control over category assignment, it can be tedious, especially for brands with extensive inventory.
A more automated solution involves using tools based on artificial intelligence, such as the one offered by Adsmurai Marketing Platform "Google Category Mapping". This tool, available for any vertical, is specially designed for e-commerce selling on marketplaces. In addition, Google Category Mapping allows easier categorization on other platforms such as Facebook or Criteo, which saves time on a task that is tedious and time-consuming. This tool automatically predicts and populates the "google_product_category" field based on product information, which saves time and effort for marketers. It also ensures that products are automatically updated if Google changes their categories.
⚠️ Google regularly updates its taxonomy to adapt to the market, so keeping your feed up-to-date isn't optional; it's mandatory if you want to stay competitive.
This option combines automated category assignment with manual intervention when necessary. For example, you can use automatic categorization for most products and then make manual adjustments for those that require more specific categorization.
Regardless of the method chosen, it is essential to ensure that products are categorized correctly. This can be achieved by providing high-quality titles and descriptions, as well as accurate price, brand, and GTIN (Global Trade Item Number) information, which will help products rank appropriately in Google's constantly evolving product taxonomy.
You automate what you can and manually adjust what needs a more human touch. The perfect balance if you have complex or unconventional products.
The importance of Google Product Category lies in several key factors that help improve both marketing campaign performance and the overall user experience:
✅ Greater relevance and CTR: Google shows your products to users who are actually interested.
✅ Campaign optimization: Allows for better segmentation, smarter budget control, and improved results.
✅ Compliance with regulations: Mandatory for categories like software, apparel, or books.
✅ Correct tax application: Especially important in countries like the U.S.
✅ Multichannel consistency: Facebook, Criteo and other platforms also rely on this categorization—get it right once, benefit everywhere.
Properly categorizing your products in Google Product Category is essential to boost campaign performance, improve ad relevance, and deliver a better shopping experience across multiple sales channels.
When assigning product categories in your Google Shopping feed, following a few best practices will help ensure accuracy and relevance:
There are no secrets just some tips that actually work:
🔄 Keep your feed up to date. Google updates its taxonomy frequently.
🎯 Be specific. Use the most precise category available.
✅ Only one category per product. Nope, you can’t assign multiple.
🌍 Adapt by country. Each region has its own taxonomy and tax rules.
🔍 Use product_type
if there’s no exact match. Gives you more flexibility.
🧠 Check the official taxonomy and avoid outdated categories from 2011.
💡 Pro tip: Describe your product clearly (title, brand, GTIN, etc.) so the mapping tool can do its job more accurately.
By following these recommended practices, you’ll be able to optimize how your products are categorized on Google Shopping, increase ad relevance, and create a smoother shopping experience for users.
A lot more than you might think.
This attribute doesn’t just help Google approve your ad—it also determines:
Which users see it
Which search queries trigger it
Whether or not it complies with Google’s editorial and advertising policies
If you get it wrong, you might:
Miss out on relevant impressions
Overpay per click
Get your products rejected for non-compliance
🎬 Example: For books or movies, it's often more appropriate to list the publisher as the brand instead of the manufacturer. But Google can only interpret that correctly if the product category is accurate.
