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.

VLINK ASIA

Find every broken or redirecting internal link in your WordPress content, and fix them in bulk.
VLink Broken Links Scout reads your content straight from the database, so the front-end never gets crawled and visitors are never slowed down. Every fix is preceded by a one-click-restorable snapshot, so you can replace links across hundreds of posts without fearing a typo.
<h4>How it works</h4>
<ol>
<li>Scan your content for internal links.</li>
<li>Check each URL with a real HTTP request and classify the response.</li>
<li>Fix broken URLs and permanent redirects (301 / 308) one at a time or in bulk.</li>
</ol>
<h4>What gets flagged</h4>
<ul>
<li>Broken: 404 Not Found, 410 Gone.</li>
<li>Safe to auto-replace: 301 Moved Permanently, 308 Permanent Redirect.</li>
<li>Informational only: 302 / 303 / 307 (the original URL is still authoritative, so the plugin will not auto-replace them).</li>
</ul>
<h4>How you fix things</h4>
<ul>
<li>One link at a time: open the Change Link modal, see the suggested target, replace across every post that uses it.</li>
<li>In bulk: filter by status, preview the diff, then apply.</li>
<li>Always reversible: every fix creates a snapshot you can restore in one click.</li>
<li>Audit trail: every change is logged with old URL, new URL, posts touched, user, and timestamp.</li>
</ul>
<h4>Built for safety</h4>
<ul>
<li>Snapshot before every change. Restore is one click away.</li>
<li>Background work runs in small bounded batches with retry on timeout, so visitor requests are never blocked.</li>
<li>Optional scheduled scan with a clean HTML email summary.</li>
<li>RFC 3986 and RFC 9110 compliant URL handling, so http vs https, www vs non-www, and trailing slash variants are all matched correctly.</li>
</ul>
<h3>Privacy</h3>
The plugin does not collect, store, or transmit personal data about visitors or administrators. No third-party API calls. No telemetry. No analytics. No call-home.
The only outbound traffic is HTTP requests to the URLs already present in your own content, in order to read their response codes. No cookies, no Referer header, and no request body are sent.
The optional scheduled-scan email report sends a plain summary to the WordPress admin address you configure; nothing leaves your server otherwise.

VLink Broken Links Scout

Scan the WordPress database for internal links that return 404, 410, or 301/302 redirects, and fix them in bulk. RFC 3986 and RFC 9110 compliant.
