# Check for broken links

Broken links frustrate users, hurt SEO rankings (Google penalizes 404s), and damage credibility—especially for documentation and e-commerce sites.

## Quick Reference

- Use lychee, linkchecker, or broken-link-checker npm packages
- Check internal, external, anchor, and mailto links
- Integrate into CI/CD for automatic detection
- Set up regular monitoring for external link rot

## Check

Verify that all internal and external links are working properly and don't return 404 errors or redirect to unintended destinations.
