Niquelao Link Guard

Niquelao Link Guard is a WordPress plugin developed by Koke Pérez that focuses on identifying and assisting with the repair of broken links on WordPress sites. Its primary function is to detect broken links, both internal and external, and provide users with tools to address these issues efficiently. The plugin is designed to minimize the impact on hosting performance by employing incremental scanning, analyzing only new or edited content when each post is saved, rather than repeatedly scanning the entire site. To further reduce server load, Niquelao Link Guard performs HTTP checks in batches using background processes scheduled via cron jobs. Users can configure the batch size and the pause between requests, allowing for tailored resource management. The plugin also implements a strategy to decrease false positives by retrying link checks with increasing delays—specifically after 1, 3, and 7 days—and by honoring the Retry-After HTTP header before marking a link as broken. Responses with HTTP 403 errors and timeouts are not immediately classified as broken but are instead flagged for review. For broken internal links, Niquelao Link Guard provides local suggestions to help users resolve the issues. The plugin's approach is tailored to avoid unnecessary strain on server resources while maintaining accuracy in link detection. The evidence does not specify pricing, licensing details, or particular user roles, but it is positioned as a tool for WordPress site management. The plugin is delivered as a WordPress extension, integrating directly into the WordPress platform.
