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.

The “External Links Overview” plugin scans your WordPress posts and pages for outgoing external links and presents them in a searchable, filterable, and sortable table. It helps you optimize your outbound link profile and identify broken or potentially harmful links.
All plugin functions, options, and database entries use the prefix <code>seokelo_</code> to prevent conflicts with other plugins.
