Smart 404 Redirect by Puzzle Sideral helps site owners fix broken URLs without digging through server logs.
The plugin captures public 404 requests, groups repeated hits, and uses a local Smart Match engine to compare the broken URL with your published WordPress content. When it finds a likely match, you can create an internal 301 redirect with one click.
Features:
<ul>
<li>Captures public 404 URLs automatically.</li>
<li>Groups repeated hits and shows last referrer when available.</li>
<li>Local smart matching based on URL slug, post title, and keywords.</li>
<li>One-click internal 301 redirects from the admin screen.</li>
<li>Manual redirect target field for edge cases.</li>
<li>Simple Witflow-style dashboard with status cards and active rules.</li>
</ul>
The smart matching runs locally inside WordPress. It does not send URLs or content to external AI providers.
<h3>Privacy</h3>
This plugin stores broken URL paths, hit counts, timestamps, and the last referrer URL when available. It does not store visitor IP addresses and does not send captured URLs to third-party services.

Broken Link Checker for YouTube is a WordPress plugin that will automatically validate 
YouTube embeds found in your published posts content using the official API.
It does this by extracting video IDs from each post and querying the YouTube 
API to ensure those IDs are still valid. This is a MUST for any video 
site that wants to retain their visitors and not annoy them with broken 
content.
The truth is videos are uploaded and removed frequently – either by the user 
or the site itself for usage violations. If this happens to a video you have 
embedded on your site, your visitors are going to see broken content instead 
of the video they expected. Don’t let that happen.
