System Architecture - Link Checking Pipeline: - Weekly Cron Trigger: Schedules the workflow to run weekly. - Scan Blog with HTTP: Performs HTTP GET requests to check website links. - Alert and Tracking Flow: - Filter Broken Links: Identifies and separates broken links. - Send Slack Alert: Notifies the team via Slack about broken URLs. - Create Broken Links List: Compiles a list of broken links. - Non-Critical Handling: - No Action for Valid Links: Skips valid links with no further action.

Implementation Guide - Import the workflow JSON into n8n. - Configure the HTTP node with the target website URL (e.g., https://yourblog.com). - Set up Slack credentials for alerts. - Test the workflow with a sample website scan. - Monitor link checking accuracy and adjust HTTP settings if needed.

Technical Dependencies - HTTP request capability for link scanning. - Slack API for team notifications. - n8n for workflow automation and scheduling.

Customization Possibilities - Adjust the Cron trigger to run at a different frequency (e.g., daily). - Customize HTTP node to scan specific pages or domains. - Modify Slack alert messages in the Send Slack Alert node. - Enhance the Create Broken Links List node to save results to a Google Sheet or Notion. - Add email notifications for additional alert channels.
