Niquelao Link Guard

Developed by Koke Perez.

Niquelao Link Guard finds the broken links on your site and helps you fix them, with an approach designed to avoid hurting your hosting performance and to reduce false positives.

Key differences:

• Incremental scanning: it only analyzes new or edited content (when each post is saved), instead of re-scanning the whole site over and over.
• Low resource usage: HTTP checks run in batches in the background via cron, never during your visitors page loads. Batch size and pause between requests are configurable.
• Fewer false positives: retries with increasing delays (1, 3 and 7 days) and respect for the Retry-After header before confirming a link as broken. 403 responses and timeouts are marked as “review”, not “broken”.
• 100% local suggestions: for broken internal links, it proposes the correct URL by matching slug/title against your own database. For 301/302 redirects, it suggests updating to the final URL. No AI calls, no API keys, no subscriptions.
• Bulk fixing: remove the link keeping the text, replace it with the suggested or a manual URL, or mark it as ignored, all from the admin panel.
• Undo history / trash: every change is logged and can be reverted. Content edits are restored from the WordPress revision created before the change, and deleted or ignored records can be restored too.
• Security scan (local): flags suspicious or malicious links using local heuristics – spam keywords, text/target mismatch (phishing), obfuscated URLs, risky TLDs, URL shorteners, dangerous schemes – plus injected content like scripts, iframes and hidden text. A risk level and its reasons are shown for full transparency.
• Transparency: each result shows the exact HTTP status code and the reason for its classification.
• Prioritization: links are sorted by number of occurrences so you fix the highest-impact ones first.
