Hikari Category Permalink is a WordPress plugin designed to enhance permalink structures by allowing post authors to select which category is used in the permalink for each post. This flexibility addresses the default behavior of WordPress that uses the category with the lowest ID, which can hinder SEO optimization. With this plugin, users gain greater control over how their content is categorized and displayed in URLs, thus improving search engine visibility.

The plugin is a fork of the original sCategory Permalink and retains its features while offering improved stability and simplicity. Users can easily choose the desired category for each post directly from the edit page. Posts without a designated category will default to WordPress's standard behavior. Additionally, the plugin does not alter rewrite rules, ensuring a straightforward installation and operation. It is compatible with previous sCategory Permalink settings, making the transition seamless.
