Why broken links matter
Broken links (404s, 410s, server errors) frustrate users, waste crawl budget, and can dilute link equity when internal links point to dead pages. External broken links reduce trust and can cause referral traffic loss. Regular audits keep both user experience and technical SEO healthy.
Internal 404s
Fix or redirect them. Update menus, footers and content that still point to removed pages.
External 404s
Replace the link with a live alternative or remove it if no longer relevant.
Redirect chains
Long chains slow crawlers and users. Point links directly to the final destination.
How to use this tool
- Paste the full URL of the page you want to check.
- Click Scan for Broken Links. Results show link status (demo simulation).
- Copy or download the report and fix any 404s or redirects on your site.

Best practices
- Audit high-traffic and money pages first.
- Set up 301 redirects for permanently moved content.
- Monitor server logs or Search Console for 404 spikes after site redesigns.
- Use a consistent trailing-slash and protocol policy to reduce unnecessary redirects.
Frequently asked questions
Is this a live crawl?
This version returns realistic demo data for illustration. Production deployments can connect to a live crawler API.
How often should I check?
After major content updates, migrations, or at least quarterly for medium-to-large sites.
What status codes should I worry about?
4xx (especially 404/410) and 5xx. Soft 404s (200 status with “not found” content) also need attention.
