About the Broken Link Checker & URL Validator
Broken links (404 errors) create dead ends for users and waste search engine crawl budget. Accumulating broken links degrades user trust, increases bounce rates, and signals poor site maintenance to search engines.
Regularly auditing your site's links ensures that all internal navigation paths and outbound references resolve properly to live, functioning pages.
This Broken Link Checker allows you to paste a batch of URLs to validate formatting and syntax, run client-side availability verification, and launch one-click test sessions in secure tabs.
A common cause of broken internal links is renaming a URL slug or migrating pages without setting up permanent 301 redirects from the old URL to the new one. For external links, third-party sites frequently shut down, reorganize, or delete content over time (link rot).
Tip: Perform quarterly broken link audits across your top landing pages and set up 301 redirects whenever updating or retiring existing page URLs.
