Dead Link Checker - SEO and 404 error Fix

Broken links frustrate your visitors and hurt your search rankings. When someone clicks a link on your site and lands on a 404 page, they lose trust — and so does Google. Dead Link Checker scans your WordPress posts and pages, finds broken links, and gives you a clear report so you can fix them quickly. It runs in the background without slowing down your site. Whether you have a personal blog or a large content site, keeping your links healthy is one of the simplest things you can do for on-page SEO. This plugin handles the heavy lifting so you don't have to check every link by hand. How It Works

1. Go to Dead Link Checker → Dashboard in your WordPress admin.
2. Click Scan Now to start scanning your content.
3. The plugin checks every link in your posts and pages.
4. Broken links, redirects, and slow responses show up in a visual report.
5. Fix or dismiss links directly from the dashboard.

The scanner runs in small batches. This keeps your server running fast. It will not slow down your website for visitors.
