It supports various post import plugins and is capable of handling custom taxonomies and post types, including WooCommerce products, making it versatile for different website needs.

The plugin also accommodates UTF-8 characters, allowing for the inclusion of non-Latin and logographic alphabets, such as Arabic and Chinese.

Users can create configuration groups with custom rules and utilize wildcard (regex) support for advanced keyword management.
