Delete Duplicate Products for WooCommerce

الأسئلة المتكررّة

What is the difference between the free and Pro versions?

The free version lets you find all duplicate groups, use the page-level “Select all — keep newest/oldest” buttons, and perform bulk actions on up to 10 groups per day (the counter resets at midnight UTC). Pro removes the daily limit entirely and also adds 301 automatic redirects, filter by category, per-group Keep Newest/Oldest buttons, and CSV export.

Does the plugin work with large catalogs (10,000+ products)?

Yes. Version 1.3.0 specifically addresses performance issues reported with large catalogs. Duplicate detection queries run at the database level with proper indexing, pagination is applied correctly, and the JavaScript has been optimized using event delegation so the interface remains responsive even with hundreds of products visible.

Why was my SKU-based search showing products that are not duplicates?

This was a bug in previous versions. The WooCommerce product query used a partial (LIKE) match for SKUs, so searching for SHIRT-001 would also find SHIRT-001-S, SHIRT-001-M, etc. Version 1.3.0 fixes this by using an exact SQL match, so only products with the exact same SKU are grouped together.

What are “Keep Newest” and “Keep Oldest”?

There are two levels. The free page-level buttons (“Select all — keep newest” / “Select all — keep oldest”) appear in the toolbar and act on every duplicate group on the current page at once — ideal for processing hundreds of groups quickly. The Pro per-group buttons appear on each individual group and let you select within that group independently. Both work the same way: they check all products except the one to keep, so you can immediately hit “Apply”.

How does the CSV export work?

The CSV export (Pro) downloads a file with all duplicate products found under the current filters. Each row contains: duplicate group name, product ID, title, SKU, price, status, categories, creation date, and URL. The file is UTF-8 encoded and compatible with Excel, Google Sheets, and other spreadsheet tools.

Can I filter duplicates by product category?

Yes, with the Pro version. A category dropdown appears in the filters section. Selecting a category shows only duplicate groups where the products belong to that category.

How do the automatic 301 redirects work?

This is a Pro feature. When you permanently delete a duplicate product, the plugin automatically creates a 301 redirect. This sends anyone visiting the old URL to a new, active page. You can configure the destination on the “Duplicate Products > 301 Redirects” page. The options are: redirecting to the main product of the duplicate group (the canonical product), to the product’s category, or to your homepage. This is crucial for SEO and user experience.

What is a “canonical product”?

In a group of duplicate products, the “canonical product” is the one you decide to keep. When you delete the other duplicates, the plugin uses the canonical product as the target for 301 redirects.

Can I recover products after moving them to trash?

Yes, products moved to trash can be restored from the WooCommerce or WordPress trash section, as long as they have not been permanently deleted.

Does the plugin delete images from the media library?

Yes, when you use the image removal features, the images associated with the product are permanently deleted from your media library. This action cannot be undone.
