Users appreciate the Yoast Duplicate Post plugin for its simplicity, ease of use, and functionality, especially for duplicating posts/pages and working seamlessly with major themes and plugins like Elementor. It's a great time-saver and reliable for creating template-like versions of content. However, several drawbacks are noted. Users report conflicts causing 404 errors, internal server errors, compatibility issues with custom post types and WooCommerce, and performance slowdowns. Additionally, many are frustrated with frequent and intrusive ads, notifications, and some unintended feature changes post-acquisition by Yoast, such as resetting user settings and automatic canonical URL settings. The plugin’s reliability varies, causing significant issues for some users.
