Weekly Website Link Checker with Slack Alerts for Broken URLs

This n8n workflow automates the monitoring of website link integrity by running weekly scans via HTTP GET requests to detect broken URLs. It starts with a Cron trigger to schedule checks, performs scans on specified site sections like blogs, filters out valid links, and identifies broken ones based on status codes (e.g., 404). For detected issues, it sends targeted Slack notifications to your team and generates a compiled list of broken links with details like URL, status, and timestamp for easy follow-up.

The benefits include proactive maintenance of site health, preventing user frustration from dead links, improving SEO rankings, and ensuring a seamless experience—especially critical for e-commerce sites where broken product or payment links can lead to lost sales. It saves hours of manual checking, reduces downtime risks, and integrates effortlessly with n8n's no-code environment for reliable automation.

Ideal use cases span e-commerce platforms monitoring product pages and checkout flows, blogs ensuring post links work, or corporate sites maintaining resource integrity. Customize the Cron for daily runs, target specific URLs, or extend to email alerts. No database needed; it processes HTTP responses on-the-fly, making it lightweight yet powerful for IT and development teams.
