Powerful, lightweight, and modern broken link scanner for WordPress. Detect, monitor, and fix broken links with a real-time AJAX dashboard and multilingual support.

== Description ==

**LinkGuard NT** is a modern and high-performance broken link checker designed for WordPress sites of all sizes — from small blogs to large content-heavy platforms.

It scans posts, pages, custom post types, and external links to detect:

- ❌ Broken URLs (404, 410, 500, DNS errors)
- ⚠️ Redirected URLs (301/302)
- ⛔ Blocked or unreachable links
- 🔗 Mixed content issues (HTTP vs HTTPS)
- 🌐 External domains that are down or expired

All results appear instantly inside a real-time, AJAX-powered dashboard.

### 🚀 Why LinkGuard NT?
Unlike traditional link checkers, LinkGuard NT:

- Runs fast and asynchronously  
- Uses optimized SQL queries  
- Has a clean and intuitive interface  
- Provides built-in security (nonces, sanitization, prepared SQL)  
- Includes multilingual support (English + Turkish)  
- Is fully modular and extendable  

This makes it ideal for SEO maintenance, content auditing, and large WordPress websites.
