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.

Good Plugin

Find and fix broken links across your entire WordPress site without opening each post.

Ilias Chelidonis

Check for Broken Links scans your entire WordPress site for broken links, dead links, and 404 errors — and alerts you the moment something breaks, before Google finds it first.
Your site breaks quietly while you are busy. Pages get deleted, plugins get abandoned, external sites go offline. You had no idea. Check for Broken Links finds every broken link across your posts, pages, custom post types, comments, and slider content, and shows you exactly where each one was found so you can fix it fast.
Free Version
Run manual scans anytime and get a full results table showing every broken link, its status code, and exactly which page it was found on. Filter by type, export to CSV, and stay in full control with no automatic changes to your content.
Pro Version — Set It Once, Forget It
Pro runs automatic scheduled scans daily, weekly, or monthly and emails you. No manual checking, no guessing — just a silent background monitor that alerts you when something needs your attention.

Check for Broken Links


This plugin does the job well for pages, posts and comments. However, it does not scan the entire site, as it does not include searching to dead links in Custom Post Types - so this is my only reason for my 4 stars as oppose to 5.



UPDATE: After that awesome response, which is refreshing as some others resist and give excuses, I'm updating my review to 5 stars, can't wait for the next update - you guys are awesome and deserve it...


Works well, but lacks support for CPT.


No membership, no cloud, no muss, no fuss. Just works. Thank you :)


Perfect


Simple but effective and works as it should, thank you author.
