Duplicate product errors in Google Merchant Center do not always trigger immediate suspension, but they cause product disapprovals, waste ad budget on competing listings, and in some cases get flagged as misrepresentation. This guide covers what causes duplicates, how to find them, and how to clean them up.
Scan Your Feed for Duplicate Products (Free)Google considers products duplicates when two or more listings share any of the following:
The most common cause: you connected your Shopify store directly via the Google and YouTube app, and you also have a supplemental feed or spreadsheet feed that includes the same products. Both sources send the same GTIN to Google. Fix: remove the product from one of the two sources.
If you migrated from Shopify to WooCommerce (or vice versa), the old store's feed may still be active in GMC. Products from the old feed and the new feed share GTINs. Fix: go to Feeds in GMC and deactivate or delete the feed from the old store.
Submitting a product as a standalone listing AND as a variant within a product group creates duplicates. Choose one: either submit all sizes/colors as variants under a shared item_group_id, or submit each as a standalone product. Not both.
When you edit a product in GMC's Product editor and it creates a new entry instead of updating the existing one, you end up with two active listings for the same product. This happens with some third-party feed apps.
gtin column. Any rows with identical GTIN values are duplicates.link (landing page URL) to catch duplicates that share a URL but have different GTINs.Remove one of the duplicate rows from your feed file. Keep the one with the more complete data (better description, correct GTIN, proper image URL). After removing, resubmit the feed and allow 24 to 48 hours for Google to re-process.
Go to Products › Feeds and identify which feed is the source of each duplicate. Delete the product from the secondary feed, or deactivate the secondary feed entirely if it is no longer needed.
Choose one submission method. If you want to submit variants, assign an item_group_id to all variants and give each a unique id with distinct color, size, or other variant attributes. Remove any standalone listings for the same product.
Duplicate products become a misrepresentation issue when they appear to mislead Google about how many distinct products you sell, or when the same product is submitted with inconsistent pricing across duplicate listings. If GMC shows your suspension reason as misrepresentation and you have duplicates in your feed, fix the duplicates first before submitting an appeal.
After removing duplicate rows and resubmitting your feed, check Diagnostics in GMC for 48 to 72 hours. The duplicate errors should clear. If they persist, use the Products report to check whether old cached listings are still showing as active. You may need to explicitly delete the duplicate product IDs via the GMC Products API or the manual "Remove" option in the Product editor.
Get a Free Duplicate Product AuditDuplicate products occur when two listings share the same GTIN, identical landing page URL, or word-for-word matching title and description. The most common cause is submitting the same products through multiple feed sources.
Not directly in most cases. Duplicates cause product disapprovals and wasted ad spend. Repeated patterns of duplicates, especially with inconsistent pricing, can lead to a misrepresentation flag which does cause suspension.
Filter your Products view by "Disapproved" and look for "Duplicate" in the issue column. For a full audit, export your feed as CSV and sort by the GTIN column.
No. Submitting the same products across multiple accounts is a policy violation and can trigger suspension of both accounts.
