TSO Link Inspector scans all published posts, pages and custom post types for links, then checks each one via HTTP to detect broken links, redirects, insecure HTTP URLs and connection errors. All results are displayed in a dashboard where you can fix links directly without opening the editor.
<h4>Key Features</h4>
<ul>
<li>Scans posts, pages, and any custom post type.</li>
<li>Detects HTTP errors: 404, 410, 500, DNS failures, SSL errors, timeouts, and redirects.</li>
<li>Edit URLs inline directly from the admin panel, no need to open the editor.</li>
<li>Smart URL Suggester: automatically tests HTTPS upgrade, follows redirect chains, and tries www/non-www variants.</li>
<li>Unlink: removes the <code><a></code> tag but keeps the visible text.</li>
<li>Bulk actions: re-check, unlink, mark as OK, or delete multiple links at once.</li>
<li>Export CSV: export any filtered view to a spreadsheet.</li>
<li>Per-article view: click any article to see all its links in one place.</li>
<li>HTTP insecure detection: flags active links still using HTTP instead of HTTPS.</li>
<li>Ignore list: add domains or URL prefixes to never scan or check.</li>
<li>Scan images and iframes: optionally detect broken <code><img src></code> and embedded videos.</li>
<li>Scan user comments: optionally check links in approved comments.</li>
<li>Custom fields (ACF): optionally scan URL fields added by plugins like Advanced Custom Fields.</li>
<li>Daily automatic scan and hourly batch check via WP-Cron. Can close the browser while checking.</li>
<li>Email alerts for fully broken links (no redirect): send one summary after automated checks, or a periodic digest (7 / 15 / 30 days), with an optional notification address.</li>
<li>Nofollow broken links: automatically adds <code>rel="nofollow"</code> to broken links so search engines ignore them.</li>
<li>Preserve post dates: editing a link does not update the post modification date.</li>
<li>Compatible with LiteSpeed Cache, WP Rocket, W3 Total Cache, WP Super Cache, SG Optimizer, Breeze, and Cloudflare.</li>
<li>Extended scanning: plain-text URLs in posts, Gutenberg block JSON, navigation menus, responsive media (srcset/picture), page-builder <code>data-*</code> attributes, widget sidebars, taxonomy descriptions, Site Editor templates/reusable blocks, and plain URLs in custom fields.</li>
<li>Third-party sources: register extra link collectors with <code>tsoliin_register_link_source()</code>.</li>
<li>Includes Catalan and Spanish translations.</li>
</ul>
<h4>How it works</h4>
<ol>
<li>Click Scan now to extract all links from your posts.</li>
<li>Click Check now to send HTTP requests to every URL (runs server-side, you can close the browser).</li>
<li>Review results using the Broken, Redirect, HTTP insecure and other filter tabs.</li>
<li>Fix links using Edit URL, Suggestion, Unlink or Mark as OK from each row.</li>
</ol>
<h4>Redirect intelligence</h4>
The plugin follows the full redirect chain manually so it captures the real final destination, not just the last HTTP code. It automatically ignores trivial redirects (trailing slashes, CDN tokens, WP attachment pages, login walls) to avoid false positives.

Link Diagnostics is a comprehensive link analysis tool that scans your WordPress site for link issues and provides detailed intelligence about your internal linking structure. If you’re serious about SEO and site maintenance, this plugin gives you the visibility you need to keep your links healthy.
For a detailed feature breakdown, screenshots, and technical overview, see the official 
<a href="https://swiftspeed.app/link-diagnostic-and-insights-plugin/" rel="nofollow ugc">Link Diagnostic and Insights product page</a>.
<h4>Why Link Health Matters for SEO</h4>
Over time, your site accumulates link problems. You delete old posts, change slugs, restructure content. Automated or manual redirect plugins create chains. External sites you have linked to in the past go offline. The result:
<ul>
<li>Redirect chains that waste crawl budget and slow page speed</li>
<li>Broken internal links that hurt user experience and rankings</li>
<li>Orphaned content that search engines can’t discover</li>
<li>Dead external links that signal poor maintenance</li>
<li>Inefficient internal linking that fails to pass authority to important pages</li>
</ul>
These issues directly impact your SEO health score in tools like Ahrefs, Semrush, and Screaming Frog. Link Diagnostics helps you fix them systematically.
<h4>Internal Link Health – The Big Win</h4>
This is where the plugin delivers maximum value. When you change a URL or delete a post, redirect plugins create a 301 redirect. Fine for visitors, but now you have anchor texts across your site linking to URLs that redirect elsewhere. Every redirect hop wastes crawl budget and dilutes link equity, seo tools detect it and tell you to fix, but then, your site is large, how many do you want to start fixing one after the other? well, that’s why this plugin exists.
What Link Diagnostics does:
Scans every post and finds anchor texts linking to redirected URLs. You see:
<ul>
<li>The post containing the link</li>
<li>The anchor text used</li>
<li>The current URL being linked to</li>
<li>Where that URL redirects to</li>
<li>The redirect type (301, 302, 307, 308)</li>
</ul>
Click “Fix” and the plugin updates the anchor’s href to point directly to the final destination. No more redirect chains. Your internal links point exactly where they should.
For a deeper explanation of how internal redirect chains affect crawl efficiency and SEO performance, refer to the 
<a href="https://swiftspeed.app/link-diagnostic-and-insights-plugin/" rel="nofollow ugc">Link Diagnostic and Insights documentation</a>.
Why this matters:
<ul>
<li>Preserves crawl budget by eliminating unnecessary redirects</li>
<li>Passes full link equity directly to target pages</li>
<li>Improves page speed (fewer redirect hops)</li>
<li>Boosts SEO health scores dramatically</li>
<li>Strengthens your internal linking structure</li>
</ul>
This one feature alone can move your site health score from 60% to 90%+ in SEO tools.
<h4>Other Internal Link Issues Detected</h4>
Beyond redirects, the plugin finds:
<ul>
<li>404 Errors: Broken internal links where the target page doesn’t exist</li>
<li>410 Gone: Links to permanently deleted content</li>
<li>500 Errors: Server errors on internal URLs</li>
<li>Redirect Chains: Multiple redirect hops before reaching destination</li>
</ul>
Each issue shows the source post, anchor text, problematic URL, and HTTP status code. Fix them directly from the admin panel.
<h4>External Link Error Detection</h4>
Your outbound links matter too. Link Diagnostics scans external links and reports:
<ul>
<li>404 and 410 errors (broken external links)</li>
<li>5xx server errors (unreliable external sites)</li>
<li>DNS failures and timeouts (unreachable domains)</li>
<li>Redirect chains on external URLs</li>
</ul>
You see which posts contain broken external links and can update or remove them to maintain content quality.
<h4>Link Intelligence – Understand Your Link Structure</h4>
This is the strategic part. Beyond finding problems, Link Diagnostics analyzes your entire link structure to reveal:
Most Linked Internal Pages
See which pages receive the most internal links. These are your content hubs and authority pages. You can:
<ul>
<li>Verify your most important pages are well-linked</li>
<li>Find pages that are over-linked or under-linked</li>
<li>Identify pillar content opportunities</li>
<li>Balance internal link distribution</li>
</ul>
Each page shows total inbound links and expandable details listing every source post with the exact anchor texts used.
Common Anchor Texts
Discover which anchor texts you use most frequently. This helps you:
<ul>
<li>Spot over-optimization (too many exact-match anchors)</li>
<li>Find opportunities for natural language variation</li>
<li>Maintain consistency across your content</li>
<li>Avoid anchor text patterns that look spammy</li>
</ul>
External Domains Analysis
See which external sites you link to most often. This reveals:
<ul>
<li>Your most frequently cited sources</li>
<li>Over-reliance on specific domains</li>
<li>Opportunities to diversify external links</li>
<li>External relationships worth maintaining</li>
</ul>
For each domain, see which posts link to it and what anchor texts are used.
Orphaned Pages
Find content with zero internal links. These pages are invisible to crawlers and users. Link Diagnostics lists every orphaned page so you can:
<ul>
<li>Add internal links from relevant content</li>
<li>Improve site-wide content discovery</li>
<li>Boost the authority of isolated pages</li>
<li>Ensure all content is accessible</li>
</ul>
<h4>URL Redirect Management</h4>
Built-in redirect manager handles site restructuring and migrations:
<ul>
<li>Create 301, 302, 307, and 308 redirects</li>
<li>Add multiple source URLs to one destination in bulk</li>
<li>Organize redirects with categories</li>
<li>Toggle redirects active/inactive without deletion</li>
<li>Bulk delete operations</li>
<li>Source URL uniqueness validation prevents conflicts</li>
</ul>
Perfect for handling old URLs after site migrations or content reorganization.
<h4>How Scanning Works</h4>
Click “Start Scan” on any tab. The plugin:
<ol>
<li>Queries your published content (posts, pages, custom post types)</li>
<li>Extracts all links from post content</li>
<li>Checks each URL via WordPress HTTP API</li>
<li>Stores results in custom database tables</li>
<li>Shows progress in real-time</li>
</ol>
Scans are on-demand only. No background processing, no automated changes. You control when to scan and what to fix.
