You deleted a product in Merchant Center yesterday. This morning it’s back, and there’s a duplicates warning as well. This guide is for store owners who need to delete products in Google Merchant Center, remove a whole data source or clear the “Duplicate product” and “Duplicate identifier” issues. By the end you’ll know where to click, what to change on your store first and how to stop the same items returning.
Delete the product at its source first (your store or feed file), then delete it in Merchant Center under Products & store > All products. If you skip the source, the product is added again on the next upload[1]. For duplicates, open the issue by its exact name, edit the affected products so each has its own unique values and save[4][5].
Good to know
The menu paths, limits and issue names below come from Google’s help pages[1][2][3][4][5][6]. Anything else is our own advice. Where something is a judgement call rather than Google’s guidance, the text usually says so.
Why deleted products keep coming back
Merchant Center reflects whatever your data sources send it. Products arrive through a data source, which is the feed file, the Shopify or WooCommerce connection or an API link that supplies your product data. If the product still exists in that source, the next upload puts it back[1]. Deleting inside Merchant Center alone does not fix the cause.
That’s the first thing to check when a product reappears. Before you click anything, decide where the product lives and where it should stop living. If feeds are new to you, the basics are covered at https://oxfordimpulse.com/beginners-guide-google-merchant-center-feed/ and are worth reading before you start deleting.
Step 1: Remove the product at the source
Do this before you touch Merchant Center.
- Find the product in your store admin (Shopify, WooCommerce or whichever platform you use) or in your feed spreadsheet.
- Delete it or remove its row from the feed file, whichever matches how your data source picks up products. If you aren’t sure which your setup uses, check the data source settings first.
- Confirm the product no longer appears in the file or the sync your data source reads.
Watch out
A product that’s merely out of stock is still a product. If the item is coming back, mark it out of stock rather than deleting it. If you’ve stopped selling it, remove it at the source.
Watch out
If you delete the product on your site but leave it in a second data source, such as an old spreadsheet, that source keeps re-adding it[1]. Search every source for the product ID.
Step 2: Delete products in Merchant Center
Now clear the product from your account.
- Open Merchant Center and go to Products & store, then Products.
- Open the All products tab.
- Click the product title to open it.
- Choose Delete product.
This permanently removes the product from your account[1]. There are two limits to know about. First, Google doesn’t guarantee removal from organic results if the pages have already been crawled[1]. Second, there’s no fixed timeframe to promise for how quickly listings disappear, because pages differ.
Watch out
Products locked by a policy violation can’t be deleted until the violation is resolved[1]. If you can’t delete a product, check its issues, resolve the policy problem, then delete it. If you’re also seeing a limited status warning, https://oxfordimpulse.com/google-merchant-center-limited-status-meaning/ explains what it means.
Tip
Archived products are different from deleted ones. If a product was archived rather than deleted, you can restore it from the Archive folder[1].
Step 3: Delete a data source in Merchant Center
Sometimes you need to remove a whole feed you no longer want, like an old spreadsheet or a connection to a retired store. To delete a data source in Merchant Center:
- Go to Settings, then Data sources.
- Open the Product sources tab.
- Find the source, click the three-dot menu under Actions and choose Delete source.
- Confirm with Remove.
Once removed, the items from that source stop being available for Shopping[2]. Also remove the products at their origin, otherwise they can come back through another source.
Replacing a feed? Order matters
If you’re swapping one feed for another, upload the new data source before you remove the old one. That way item IDs and history carry over[2]. Removing the old one first puts that continuity at risk.
When deleting a source doesn’t remove the product
A product that sits in two sources belongs to the one most recently updated[2]. Delete one source and the product can stay in place, because the other source still owns it. Check which of the two sources was updated most recently, because that is the one that owns the product.
Step 4: Stop Found by Google from re-adding products
Found by Google is the automatic route for adding products from your online store[3]. Products already in other data sources aren’t added again[3]. If you want to stop managing certain products this way, use Stop managing products[3][1]. Then remove the products at the source as in Step 1, otherwise they may be picked up again.
Step 5: Fix the “Duplicate product” issue
The message means you have multiple offers with the same attributes and values[4]. In plain terms, Merchant Center sees two or more entries that look like the same thing.
Diagnose first. These are judgement calls, not Google’s list of causes: the same item exported twice under different IDs, variants that carry identical titles, links and prices or a leftover test product.
- Go to Products, then Needs attention.
- Filter by the “Duplicate product” issue.
- Click a product title and choose Edit product.
- Change the values so the offer is genuinely distinct, or delete the true copy at the source (Steps 1 and 2).
- Click Save[4].
For many products, download a .csv, edit it and re-upload it[4]. Still, if the copies come from your store, fix them at the source, or the next sync recreates them.
Step 6: Fix the “Duplicate identifier” issue
This one means multiple products share the same identifiers[5]. Identifiers are values like the GTIN (Global Trade Item Number, the barcode number), MPN (manufacturer part number) and brand. If you aren’t sure what a GTIN is, https://oxfordimpulse.com/what-is-gtin-google-merchant-center/ explains it.
The fix path is the same: Products, Needs attention, filter by the issue, open the product, Edit product, Save[5]. Then check each flagged product:
- Is the gtin typed correctly, and does it belong to this exact variant (size, colour, pack)?
- Was one barcode pasted onto several variants?
- Is it two listings of the same real product that should be one?
Watch out
Don’t invent or reuse a gtin to clear the warning. If a product has no barcode, leave the gtin out rather than copying one from another item.
Step 7: Check your IDs so duplicates don’t return
The id attribute is how Merchant Center tells products apart. Google’s guidance: use a unique ID per product, and don’t use casing to make IDs unique[6]. So “TSHIRT-RED” and “tshirt-red” aren’t a safe pair.
Know this before you rename anything: changing an ID overwrites the product and its history[6]. If you must change IDs, do it once, on purpose, and expect the old product and its history to be overwritten. Products also expire 30 days after the last refresh[1], so a feed that stops updating can eventually empty itself, which isn’t the same as a clean delete.
Step 8: Verify the result
- Reopen Products and search for the product ID or title.
- Wait for the next update from your data source, then look again.
- Check Needs attention for the duplicate issues.
- Open one of your product URLs in a private window to confirm the page matches what you intended.
If a product has returned, trace it. Check whether a second data source, Found by Google or your store connection added it again.
