Internal Link Scan
Internal links are the backbone of site structure, yet they are often left unchecked as content grows. Link Diagnostic and Insights scans your site to identify internal links that lead through unnecessary redirects, point to broken pages, or return server errors, allowing you to fix issues that dilute link equity and slow down search engine crawling.
Key capabilities
External Scan
Outbound links reflect the quality and credibility of your content, yet external pages change or disappear over time. This plugin continuously checks external links referenced across your site and surfaces unreachable URLs, 404 errors, and defunct domains so you can maintain editorial trust and avoid sending users to broken destinations.
Key capabilities
