About this plugin
VVertex Link Health Monitor checks links and image URLs found in published WordPress content and records URLs that return an HTTP error status or cannot be reached by the site’s HTTP client.
The plugin provides manual scans, batched scheduled scans, email summaries, a filterable report, CSV export, and an activity log.
Features
- Manual scans with progress updates in the WordPress admin.
- Batched scheduled scans using WordPress Cron.
- Link and image URL checks using the WordPress HTTP API.
- Configurable request timeout and scan batch size.
- Filterable report with HTTP status information.
- CSV export for recorded scan results.
- Optional scheduled email summaries.
- Activity logs for scan and email events.
How scanning works
The plugin reads published post content and extracts URLs from link ( a ) and image ( img ) elements. Relative URLs are resolved against the post URL. HTTP and HTTPS URLs are checked using WordPress safe HTTP request functions.
A HEAD request is attempted first and a limited GET request is used as a fallback when needed.
A status of 400 or higher is recorded for review. A status of 0 means WordPress could not obtain an HTTP response, which can happen because of network, DNS, firewall, TLS, or remote-server restrictions. Administrators should review reported items before changing content.
External requests and privacy
During a scan, your WordPress site sends HTTP requests directly to the URLs already present in your published content. Those URLs may point to third-party websites. The destination server can receive normal request information such as your server IP address and the plugin user-agent string.
The plugin does not send scan results, site content, or personal data to a service operated by the plugin author.
