Internal links are one of the most underrated components of WordPress SEO. They help search engines discover your content, pass authority between pages, improve crawlability, and define your site structure. Yet as websites grow, internal linking becomes harder to maintain, and important content often becomes isolated, underlinked, or even completely invisible to both users and search engines. OrphanPages provides a full internal link audit for your website. It scans all public post types, analyzes how your content links together, and identifies: Orphaned pages and posts (URLs with 0 incoming internal links) Weakly linked pages with poor link depth Moderately and strongly linked content hubs Broken outgoing links that return 404 or unreachable results External links leaving your site Full incoming and outgoing link paths Anchor text usage and linking context This plugin offers a complete overview of your site’s internal link structure, link health, broken links, and outgoing link patterns — all inside a clean, sortable, easy-to-read interface. Why internal linking matters Search engines rely heavily on internal linking to understand content relationships, assign importance to different URLs, and discover new pages. A strong internal linking strategy improves indexing speed, ranking potential, and user navigation. A weak structure leads to low crawlability, inconsistent link depth, buried content, and orphan pages. Even with an updated XML sitemap, pages without incoming internal links often fail to get indexed reliably. Fixing internal linking is one of the simplest and most impactful SEO improvements any site can make. OrphanPages helps you identify issues like: Important content with no links pointing to it New posts that were never linked from older articles Pages that exist only in menus but not in contextual links Broken internal or external links harming site quality Outdated references after site migrations or URL changes Content deep within the architecture with low crawl priority Outgoing links pointing to irrelevant, old, or redirected URLs What OrphanPages analyzes The plugin performs a comprehensive internal linking audit and reports: Orphaned posts (0 incoming links) Weak links (1–2 incoming links) Moderate links (3–4 incoming links) Strong internal linking (5+ internal references) Incoming links per page (link source, anchor text, link type) Outgoing internal links and outgoing external links Broken links such as 404s or unreachable URLs Canonical URL versions of links to avoid mismatches Internal linking patterns between posts and pages Anchor text variations and linking context Link distribution across your entire content library All results appear inside a sortable, paginated dashboard with per-post expandable details. The plugin never modifies any posts, URLs, or metadata. All analysis is read-only. Who is this plugin for?
