What Gets Checked
Broken Link Finder categorises every link on your page into one of five groups based on its HTTP response. Here's what each status means and why it matters.
404 Not Found
The most common type of broken link. A 404 error means the destination page no longer exists. This typically happens when a page has been deleted, moved without a redirect, or the URL was mistyped. These links send visitors to dead-end error pages and waste search engine crawl budget.
301/302 Redirects
Redirects aren't broken, but they're worth knowing about. A 301 redirect is a permanent redirect — the page has moved to a new URL. A 302 redirect is temporary. While a single redirect is fine, chains of multiple redirects slow down page loading and dilute link equity. Ideally, update your links to point directly to the final destination.
Connection Timeouts
A timeout means the destination server didn't respond within the allowed time. This could indicate a server that's offline, overloaded, or blocking automated requests. Timeouts create a poor experience for visitors who click these links and wait with no response.
SSL Errors
SSL errors occur when a link points to an HTTPS page with an invalid, expired, or misconfigured SSL certificate. Modern browsers will show a security warning before letting visitors through, which is almost guaranteed to make them leave. Use our SSL Checker to diagnose certificate issues in detail.
Server Errors (5xx)
5xx status codes indicate a problem on the destination server, not with your link. Common examples include 500 (Internal Server Error) and 503 (Service Unavailable). While these may be temporary, persistent 5xx errors on internal links suggest your own server needs attention.
