Broken links are one of the most common — and most overlooked — SEO issues. Every broken link on your site is a missed opportunity: lost link equity, frustrated visitors, and a signal to Google that your site isn't well maintained.
The SEO impact is real: Google's crawlers follow links to discover and index pages. When they hit a 404, that crawl budget is wasted. Pages behind broken links may never get indexed at all — meaning they're invisible in search results.
User experience matters too: Studies show that 88% of users are less likely to return to a site after a bad experience. Clicking a link and landing on an error page is one of the most frustrating experiences on the web.
Regular broken link audits should be part of every SEO workflow. Check your most important pages monthly, and always check after a site migration or URL restructure.
But finding broken links is only half the battle — make sure the pages you link to are actually indexed by Google. Use IndexFlow's Bulk Index Checker to verify.
Broken links (also called dead links) are hyperlinks on a web page that point to a URL that no longer exists or returns an error. Common broken link errors include 404 Not Found, 500 Internal Server Error, and connection timeouts. Broken links create a poor user experience and can hurt your SEO rankings.
Broken links hurt your website in three ways: 1) They create a bad user experience when visitors click a link and get an error page. 2) Google treats broken links as a quality signal — too many can lower your rankings. 3) Broken outbound links waste your page's link equity that could be passing SEO value to working pages.
The tool extracts all links from the page you enter and checks up to 50 unique links. For pages with more than 50 links, we check the first 50 and report the total count. Each link is checked with a HEAD request (falling back to GET) with a 10-second timeout.
Redirect links (301, 302) are not technically broken — the user still reaches a page. However, they add latency and the destination URL may have changed. We flag redirects separately so you can decide whether to update them to the final URL.
Check your most important pages monthly. External websites change frequently — pages get deleted, domains expire, and URLs get restructured. A monthly broken link audit helps you catch issues before they impact your SEO or user experience.
