+### **6. Monitor URL Health**
+
+The **Link Health Monitoring** feature allows you to **check if URLs are reachable** and mark them as **active or expired**.
+
+#### **Check Health Action**
+
+Use the `CheckUrlHealthAction` to **manually check the health** of a specific URL.
+
+```php
+use CleaniqueCoders\Shrinkr\Actions\CheckUrlHealthAction;
+use CleaniqueCoders\Shrinkr\Models\Url;
+
+$url = Url::find(1); // Retrieve URL instance
+
+$action = new CheckUrlHealthAction();
+$isHealthy = $action->execute($url);
+
+if ($isHealthy) {
+    echo "URL is active.";
+} else {
+    echo "URL is expired.";
+}
+```
+
+#### **Check Health Command**
+
+Use the Artisan command to **check the health of all URLs** in bulk.
+
+```bash
+php artisan shrinkr:check-health
+```
+
+This command will:
+
+1. **Check the status** of all URLs.
+2. **Mark expired URLs** and dispatch the `UrlExpired` event.
+3. **Provide real-time output** on the status of each URL.
+
+Example output:
+
+```
+URL abc123 is now marked as active.
+URL xyz456 is now marked as expired.
+URL health check completed.
+```
+
+#### **Schedule the Health Check Command**
+
+You can **automatically run the health check** at regular intervals using Laravel’s scheduler.
+
+In your **`app/Console/Kernel.php`**:
+
+```php
+protected function schedule(Schedule $schedule)
+{
+    $schedule->command('shrinkr:check-health')->hourly();
+}
+```
+
+This will ensure that all URLs are **continuously monitored** and marked as expired when necessary.
