<p>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.</p>
<p>For a detailed feature breakdown, screenshots, and technical overview, see the official<br />
<a href="https://swiftspeed.app/link-diagnostic-and-insights-plugin/" rel="nofollow ugc">Link Diagnostic and Insights product page</a>.</p>
<h4>Why Link Health Matters for SEO</h4>
<p>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:</p>
<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>
<p>These issues directly impact your SEO health score in tools like Ahrefs, Semrush, and Screaming Frog. Link Diagnostics helps you fix them systematically.</p>
<h4>Internal Link Health – The Big Win</h4>
<p>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.</p>
<p><strong>What Link Diagnostics does:</strong></p>
<p>Scans every post and finds anchor texts linking to redirected URLs. You see:</p>
<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>
<p>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.</p>
<p>For a deeper explanation of how internal redirect chains affect crawl efficiency and SEO performance, refer to the<br />
<a href="https://swiftspeed.app/link-diagnostic-and-insights-plugin/" rel="nofollow ugc">Link Diagnostic and Insights documentation</a>.</p>
<p><strong>Why this matters:</strong></p>
<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>
<p>This one feature alone can move your site health score from 60% to 90%+ in SEO tools.</p>
<h4>Other Internal Link Issues Detected</h4>
<p>Beyond redirects, the plugin finds:</p>
<ul>
<li><strong>404 Errors</strong>: Broken internal links where the target page doesn’t exist</li>
<li><strong>410 Gone</strong>: Links to permanently deleted content</li>
<li><strong>500 Errors</strong>: Server errors on internal URLs</li>
<li><strong>Redirect Chains</strong>: Multiple redirect hops before reaching destination</li>
</ul>
<p>Each issue shows the source post, anchor text, problematic URL, and HTTP status code. Fix them directly from the admin panel.</p>
<h4>External Link Error Detection</h4>
<p>Your outbound links matter too. Link Diagnostics scans external links and reports:</p>
<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>
<p>You see which posts contain broken external links and can update or remove them to maintain content quality.</p>
<h4>Link Intelligence – Understand Your Link Structure</h4>
<p>This is the strategic part. Beyond finding problems, Link Diagnostics analyzes your entire link structure to reveal:</p>
<p><strong>Most Linked Internal Pages</strong></p>
<p>See which pages receive the most internal links. These are your content hubs and authority pages. You can:</p>
<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>
<p>Each page shows total inbound links and expandable details listing every source post with the exact anchor texts used.</p>
<p><strong>Common Anchor Texts</strong></p>
<p>Discover which anchor texts you use most frequently. This helps you:</p>
<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>
<p><strong>External Domains Analysis</strong></p>
<p>See which external sites you link to most often. This reveals:</p>
<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>
<p>For each domain, see which posts link to it and what anchor texts are used.</p>
<p><strong>Orphaned Pages</strong></p>
<p>Find content with zero internal links. These pages are invisible to crawlers and users. Link Diagnostics lists every orphaned page so you can:</p>
<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>
<p>Built-in redirect manager handles site restructuring and migrations:</p>
<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>
<p>Perfect for handling old URLs after site migrations or content reorganization.</p>
<h4>How Scanning Works</h4>
<p>Click “Start Scan” on any tab. The plugin:</p>
<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>
<p>Scans are on-demand only. No background processing, no automated changes. You control when to scan and what to fix.</p>

AIOSEO Plugin Team

<p>Broken links hurt your SEO and send visitors to dead 404 pages. Broken Link Checker by AIOSEO scans your whole WordPress site for broken links and shows you exactly which ones to fix. It checks internal links, external links, broken images, and video links, then lets you fix or remove them in a few clicks without editing each post by hand.</p>
<p>This free plugin connects to your AIOSEO account and scans up to 250 internal links every month at no cost, with credits that renew each month. Upgrade to a paid subscription to scan more internal and external links, monitor more frequently, and cover larger sites. <a href="https://aioseo.com/pricing-broken-link-checker/?utm_source=wprepo&utm_medium=link&utm_campaign=liteplugin" rel="nofollow ugc">See Broken Link Checker pricing and upgrade here.</a></p>
<h4>🔗 Find Broken Internal and External Links</h4>
<p>Broken Link Checker monitors every internal link and external link on your WordPress website and reports which links work and which are broken. It crawls your content on a schedule and records the status of each link: a working 200 response, a 301 or 302 redirect, or a broken 404. You get a clear list of broken links to fix, so dead links never sit on your pages unnoticed.</p>
<h4>🎥 Check Broken Video Links on YouTube, Vimeo, and More</h4>
<p>Video links break in a way that a normal link check misses. A YouTube or Vimeo page can still load and return a working status long after the video was deleted, set to private, or removed by the uploader. Broken Link Checker auto-detects video links and verifies that the video behind each link still exists. It checks the video itself across YouTube, Vimeo, and more than ten other platforms, then flags the ones that are gone so you can swap in a working video. This keeps tutorials, reviews, and any post built around an embedded or linked video from quietly going stale.</p>
<h4>🖼️ Detect Broken Images</h4>
<p>Broken Link Checker also finds broken images. If an image file was moved, renamed, or deleted, the plugin reports the broken image URL next to your broken links so you can replace it before visitors land on a missing graphic.</p>
<h4>☁️ Cloud-Based Scanning That Does Not Slow Down Your Site</h4>
<p>Broken Link Checker by AIOSEO runs as a cloud service connected to your AIOSEO account, so the link scanning happens on our servers instead of yours. Other broken link checker plugins crawl from your own server, which can spike resource usage, get your hosting account flagged, or cause your server IP to be blocked. With cloud-based link scanning, your site speed stays the same and your hosting provider has no reason to throttle you, even on large sites with thousands of links.</p>
<h4>🎯 Granular Control Over What Gets Scanned</h4>
<p>You decide what Broken Link Checker monitors. Choose which post types to scan, such as pages, posts, and custom post types, and which post statuses to include, such as published, draft, or pending review. This keeps the scan focused on the content that matters and your link credits spent where they count.</p>
<h4>🚫 Exclude URLs You Do Not Want Checked</h4>
<p>Some links should not be checked at all. Affiliate links, tracking redirects, and third-party URLs that block automated requests can show up as false broken links. Broken Link Checker lets you exclude specific URLs and domains so your broken link report stays accurate.</p>
<h4>🛠️ Fix Broken Links Without Leaving WordPress</h4>
<p>Finding broken links is only half the job. Broken Link Checker lets you fix them straight from the dashboard. Edit a link inline to point it at the correct URL, unlink it, or remove it, and the change is written back to your post automatically. You can clear out many broken links in a single sitting instead of opening each post one at a time.</p>
<p>Broken links are also marked in red on the frontend with the Broken Links Highlighter, so they are easy to spot, and the plugin can stop search engines from following broken links while you work through them. If you use the AIOSEO Redirects feature, you can send a broken link straight to a working URL with a redirect.</p>
<h4>🏢 Who Uses Broken Link Checker</h4>
<p>Broken Link Checker works for any WordPress site that links out or links internally:</p>
<ul>
<li><strong>Bloggers and publishers</strong> – keep years of posts free of dead links and broken video embeds.</li>
<li><strong>eCommerce stores</strong> – catch broken product links, broken images, and supplier URLs.</li>

<h4>🛡️ Built by the Team at AIOSEO</h4>
<p>Broken Link Checker is built by AIOSEO, the team behind the All in One SEO plugin used on more than 3 million WordPress websites. The same focus on practical, results-driven SEO goes into keeping your links healthy and your visitors out of 404 pages.</p>
<h4>🔎 A Better Way to Check Broken Links Than Ahrefs, Screaming Frog & Other Tools</h4>
<p>If you have looked for a way to find broken links, you have probably tried tools like Ahrefs, Screaming Frog, Dr. Link Check, or Dead Link Checker. Those tools can crawl a site, but they run outside WordPress, so you copy URLs back and forth and fix every broken link by hand in the editor. Broken Link Checker by AIOSEO lives inside your WordPress dashboard. It finds broken links, broken images, and dead video links, and it fixes them in place. Because the scanning runs in the cloud, it does this without loading your server the way an on-site crawler plugin does.</p>

Broken Link Checker by AIOSEO – Find & Fix Broken Internal, External & Video Links


The moment a plugin asks me to connect to an external service, I deactivate it.



What is the point of adding a plugin to help with a LOCAL issue that does NOT need to be dealt with OUTSIDE WP??


Nope.


Do not install this module because it does not do the right thing. They don't inform you about the features and options in advance, precisely because they don't have time to help you. The free version does not completely help you to solve the problem with broken links. There are free modules that already do the job much better! I'm sorry because I wasted my time with AIOSEO (correct) or All in One SEO (correct), but not AIO SEO (incorrect) or All in 1 SEO (incorrect) or AISEO (incorrect). Who does the Branding Guideline help? Too much self-esteem and too little interest in the community!


It is not an internal tool, the data is outsourced!

Broken link checker that finds and fixes broken links, broken images, and dead video links to protect your site's SEO.
