What is Delete Duplicate Posts plugin?
Delete Duplicate Posts scans your WordPress database for duplicate posts, pages, and custom post types, then lets you review and delete them. Duplicates accumulate from importing content multiple times, migration errors, or manual copy-paste publishing. The plugin compares post titles, content, or both to identify matches.
Use with caution – always back up your database before running a bulk delete. The plugin works best for cleaning up after a bad import rather than as a routine maintenance tool. For preventing duplicates during imports, WP All Import has built-in duplicate detection that is more reliable than post-hoc cleanup.

Common Problems & Fixes
Delete Duplicate Posts is deleting posts that are not actually duplicates. How do I prevent this?
Switch the comparison method from Title Only to Title + Content for stricter matching. Review the duplicate list carefully before bulk deleting – use the preview to confirm matches are genuine duplicates. Send to Trash instead of permanent delete so you can recover false positives.
The plugin is timing out on a large database. How do I fix this?
Increase PHP max_execution_time in your hosting configuration. Run the duplicate scan in smaller batches by filtering by post type or date range. For very large databases, use WP-CLI or a direct database query to identify duplicates more efficiently.
Deleted posts are not actually removed from the site. Why?
If you chose the Trash option, posts are moved to trash and are still recoverable. Go to Posts → Trash and empty the trash. If you want permanent deletion, select the permanent delete option in the plugin settings – but back up first.
Customization & Developer Notes
Can I use Delete Duplicate Posts on WooCommerce products?
Yes – in the plugin settings, select Product as the post type to scan. This finds duplicate WooCommerce products. Be extra careful with products – duplicates may have different stock levels, prices, or variations attached. Review each match manually before deleting.
How do I schedule automatic duplicate removal?
Delete Duplicate Posts does not include scheduling. For automated duplicate prevention, configure WP All Import with its duplicate detection settings during import. For ongoing scheduled cleanup, use WP-CLI scripting to run duplicate detection on a cron schedule.
Frequently Asked Questions
Is Delete Duplicate Posts safe to use on a live site?
It is safe if you back up first and use the Trash option rather than permanent delete. Never run bulk permanent deletion on a live production site without a verified recent backup. Test on a staging site first.
What is the difference between Delete Duplicate Posts and Duplicate Post?
They solve opposite problems. Delete Duplicate Posts removes unwanted duplicate content. Duplicate Post (by Yoast) intentionally creates copies of posts for editing purposes. They are not competing tools.
Can this plugin find near-duplicates with slightly different content?
No – the plugin matches exact or near-exact duplicates based on title and/or content string comparison. It does not use fuzzy matching or similarity scoring. Slightly reworded posts with the same topic will not be detected.
Is there a WP-CLI equivalent for finding duplicates?
Yes – you can write a WP-CLI command or direct MySQL query to find posts with identical post_title or post_content values in the wp_posts table. This is more flexible for large databases and can be automated in scheduled maintenance scripts.
