I recently came across an important update from Google that I believe every retailer should pay attention to. Starting in March 2026, Google Merchant Center will implement a new requirement for multi-channel products, which are those available both online and in stores. This involves using separate product IDs when product details differ by channel.
Understanding the Changes. So, what’s changing? Essentially, online product attributes will now act as the standard. If there is a variation in the product details for in-store items, such as different pricing or availability, I’ll need to create a separate version with a distinct product ID and manage it separately in my feeds.
Steps to Take. Google has already started reaching out to affected accounts, marking products that will need updates before the March deadline. It’s critical for me to review my product data feeds to ensure that items are properly segmented between online and in-store, especially if I’m utilizing Local Inventory Ads or operating across multiple Google platforms.
The Importance of Compliance. This change is not just procedural; it’s crucial because many retailers, including myself, have been managing online and in-store versions of products under a single ID. Google’s update demands that I now explicitly separate these products when attributes like price, availability, or condition differ.
The Broader Impact. This update, while providing Google with cleaner, more consistent product data across channels, places additional responsibility on advertisers like me for feed management, especially if my inventory is complex and extensive.
Initial Announcements. This update and the communication from Google were initially highlighted by PPC News Feed founder Hana Kobzová. I’m grateful for their early insights.
Key Takeaway. If my products catalog for online and in-store are not perfectly aligned, Google’s new system requires that I start treating them as separate entities to maintain visibility and eligibility on Google’s platform.
