About CORS Limitations
Due to browser security restrictions (CORS - Cross-Origin Resource Sharing), this tool cannot fully verify all URLs from the browser.
- Working: The URL responded successfully with a valid status code
- Broken: The URL returned an error status (4xx, 5xx) or failed to respond
- CORS Blocked: The server blocked the request due to CORS policy - the URL might still be valid, but we cannot verify it from the browser
For accurate results on CORS-blocked URLs, use server-side tools or command-line utilities like curl or browser developer tools.
Quick Tips

- 3.Use the filter buttons to quickly find broken links that need fixing

Frequently Asked Questions
A link checker crawls a webpage or website to find all links (internal and external) and verifies each one works. It identifies broken links (404 errors), redirects, timeouts, and other HTTP errors that could harm user experience and SEO.
Broken links frustrate users, increase bounce rates, damage credibility, and negatively impact SEO. Search engines interpret broken links as poor maintenance, potentially lowering your rankings. Regular link checking maintains site quality and user trust.
For active websites, check monthly or after major content updates. High-traffic sites or those with many external links should check more frequently. Set up automated monitoring for critical pages to catch issues quickly before they impact many users.
Links break due to deleted or moved pages, changed URLs without redirects, expired domains, typos in URLs, external sites going offline, or restructured websites. CMS migrations and site redesigns are common causes of mass link breakage.
