Link rot happens when URLs you rely on move, change, or disappear. Broken outbound links frustrate readers, weaken credibility, and hurt SEO. You can automate detection, repair, and archiving on WordPress to protect readers and preserve the open web.
What link rot is and why to prevent it
Link rot occurs when a linked URL no longer resolves, returns an error such as 404, or redirects to unrelated content. Broken links degrade user experience, make materials feel out of date, and reduce search engine trust. Archiving linked pages preserves references and makes content more reliable. The Internet Archive’s Wayback Machine is a free nonprofit that snapshots pages over time. With the Wayback Machine Link Fixer plugin you can automatically replace broken outbound links with archived copies and proactively save linked pages.
Step 1 — Install the Wayback Machine Link Fixer plugin
From your WordPress dashboard, go to Plugins » Add New and install the free Internet Archive Wayback Machine Link Fixer plugin from the directory. Activate it and open the Link Fixer settings or follow the setup wizard that appears in your dashboard.
Step 2 — Configure the plugin
The plugin offers two core features:
– Link Fixer: scans and repairs existing broken outbound links by swapping them to archived copies when available.
– Auto Archiver: proactively saves external links when you publish or update content, or on a schedule.
Run the setup wizard from the dashboard banner or visit Link Fixer » Settings. The wizard walks you through optional API keys, selecting post types to scan, and enabling automatic archiving.
API keys (optional)
Archive.org limits daily archiving requests by default. If your site will archive very high volumes (roughly more than 4,000 links per day, mostly relevant for large publishers or automated feeds), sign up at archive.org and generate API Access and Secret keys at archive.org/account/s3.php, then paste them into the plugin settings to raise the limit. Most small and medium sites do not need keys.
Link Fixer settings
Enable Link Fixer, pick which post types to include (Posts, Pages, or custom types), and choose whether to scan existing content. Scanning a large archive can take time. Leave the action for broken links set to Replace Link (No Notification) if you want automatic replacement with archived versions, then save.
Auto Archiver settings
Enable Auto Archiver to save copies of external targets when posts are published or updated. You can also enable scheduled archiving to periodically snapshot links sitewide. Proactive archiving increases the chance an archived copy exists if the target disappears later.
Step 3 — Monitor and manage links
Use Link Fixer » Dashboard to view recent scans and archived links. The Links page lists each tracked URL with archive status, link health, check counts, and last checked date. A stats panel summarizes totals for saved, archived, broken, and ineligible links. Review these reports regularly and run manual rescans or edits when needed.
Alternative: find and fix broken links manually
If you prefer manual discovery and repair, Broken Link Checker by AIOSEO scans internal and external links and lists broken ones at Broken Links in the dashboard. From there you can edit, replace, or remove links. It runs periodic scans to catch new issues.
Frequently asked questions
1. How are broken links detected?
The checker requests each URL and inspects the HTTP response. 404 and similar errors indicate broken links.
2. What if a broken link has no archived copy?
If no snapshot exists, the plugin cannot restore the link retroactively. That is why Auto Archiver is important: it saves snapshots while targets are still live.
3. Can I scan individual posts manually?
Yes. The plugin supports manual scans of single posts or pages from the dashboard.
4. How else can I fix a broken link?
You can let the plugin replace it with an archived version, point the link to a new resource, or remove it manually.
5. Are Wayback Machine snapshots public?
Yes. Archived snapshots are added to the public Wayback Machine archive.
6. Will the plugin slow my site?
Checks and archiving run as scheduled background tasks to minimize performance impact.
7. Does fixing broken links help SEO?
Yes. Fewer broken links improves user experience and signals better site maintenance to search engines, which can improve rankings.
8. How does Wayback Machine Link Fixer differ from Broken Link Checker?
Broken Link Checker finds broken links and relies on manual fixes. Wayback Machine Link Fixer can automatically replace outbound broken links with archived copies and can proactively archive links when content is published or updated.

Conclusion
Link rot is unavoidable over time, but you can reduce its effect. Installing and configuring the Wayback Machine Link Fixer plugin preserves references, repairs broken outbound links automatically, and archives new targets proactively. Pairing it with manual scanning tools like Broken Link Checker provides full coverage. Proactive archiving and regular monitoring protect UX, support SEO, and help make the open web more reliable.
