Internet Archive

Automattic Special Projects

<p><strong>Internet Archive Wayback Machine Link Fixer</strong> is a WordPress plugin designed to combat <strong>link rot</strong>—the gradual decay of web links as pages are moved, changed, or taken down. It automatically scans your post content—on save and across existing posts—to detect outbound links. For each one, it checks the Internet Archive’s Wayback Machine for an archived version and creates a snapshot if one isn’t available.</p>
<p>When a linked page disappears, the plugin helps preserve your user experience by redirecting visitors to a reliable archived version. It also works proactively by archiving your own posts every time they’re updated, creating a consistent backup of your content’s history.</p>
<p>Protect your links, preserve your content, and automate the archiving process—all with minimal effort.</p>
<h4>Key Features</h4>
<ul>
<li>Automatically scans for outbound links in post content</li>
<li>Checks the Wayback Machine for existing archives</li>
<li>Creates new snapshots if no archive exists</li>
<li>Redirects broken or missing links to archived versions</li>
<li>Archives your own posts on updates</li>
<li>Works on both new and existing content</li>
<li>Helps maintain long-term content reliability and SEO</li>
</ul>
<h3>External Services</h3>
<p>This plugin connects to external services provided by the Internet Archive to provide its core functionality. The following information details what data is sent, when, and why:</p>
<h4>Internet Archive Wayback Machine API (web.archive.org)</h4>
<p><strong>What the service is and what it is used for:</strong><br />
The Internet Archive Wayback Machine is a digital archive of the World Wide Web. This plugin uses their API to check for existing archived versions of web pages, create new snapshots of pages, and verify the status of archiving jobs.</p>
<p><strong>What data is sent and when:</strong></p>
<ul>
<li><strong>System Status Check</strong>: No personal data is sent. Used to verify if the Wayback Machine service is online.</li>
<li><strong>User Account Validation</strong>: When you configure an API key, your access key and secret key are sent in the Authorization header to validate your account and retrieve usage statistics (available snapshots, daily limits, etc.).</li>
<li><strong>URL Archiving</strong>: URLs from your website content are sent to create new snapshots in the Wayback Machine. This includes both external links found in your content and your own post URLs when auto-archiving is enabled.</li>
<li><strong>Snapshot Status Checks</strong>: Job IDs are sent to check the status of archiving requests.</li>
<li><strong>Existing Snapshot Lookups</strong>: URLs are sent to search for existing archived versions of web pages.</li>

<h4>Internet Archive Bot API (iabot-api.archive.org)</h4>

<p><strong>What data is sent and when:</strong></p>
<ul>
<li><strong>Link Accessibility Checks</strong>: URLs from your website content are sent to check if they are accessible and to get the final destination URL after any redirects.</li>

Internet Archive Wayback Machine Link Fixer


This has been working perfectly for me, and the only slight annoyance isn't the plugin's fault or even the Archive's fault.



Some sites block the Archive from archiving them, so they appear to the link checker as broken links too.



Give a quick look through broken links on your Dashboard's Posts section from time to time, as there might be a few you'll need to add to the Link Exclusions under Advanced Settings.



The benefits far outweigh the effort it takes to monitor that yourself. :)


Working Great, check in on broken links occasionally

Automatically fix broken links by replacing them with archived versions from the Internet Archive's Wayback Machine.
