What is a Broken Link?

A broken link — also called a dead link — is a hyperlink that points to a page that no longer exists. Visitors see a 404 Not Found error. Common causes include deleted pages, restructured URLs after a site migration, expired domains, and content moved without a redirect.

Our free checker crawls up to 200 pages, tests every link, and reports every 404, 410 and 500 error — with anchor text and exact page location so you can fix issues fast.

Why Broken Links Hurt SEO

🔴Wastes crawl budget. Every broken page Googlebot visits counts against your crawl allocation.

📉Loses link equity. Backlinks pointing to 404 pages pass zero PageRank to your site.

😠Increases bounce rate. Visitors who hit a 404 leave immediately, raising your bounce rate.

⚠️Signals poor maintenance. Google views sites with many broken links as low quality.

What is a Broken Link Checker & Why Does It Impact SEO?

A broken link checker detects dead hyperlinks (404 and 410 HTTP status codes) across your website. Broken links waste search engine crawl budget on non-existent resources, degrade user engagement metrics, and break PageRank equity flow. Eliminating dead links preserves crawler bandwidth, accelerates indexing, and prevents critical search ranking drop-offs.

Frequently Asked Questions

Search engine bots have finite crawl budgets for each website. When crawlers encounter broken links (404 and 410 errors), they waste bandwidth on non-existent pages instead of indexing fresh, high-value content. Fixing dead links ensures optimal bot efficiency, uninterrupted link equity flow, and prevents ranking drops.

The scanner reports 404 (Not Found), 410 (Gone), 500 (Internal Server Error), 502 (Bad Gateway), and 504 (Gateway Timeout). Active redirects (301 and 302) are followed and verified, while 405 Method Not Allowed errors are automatically re-tested with GET requests to prevent false positives.

We recommend running a full-site broken link scan at least once a month for small sites, and weekly for large e-commerce or publishing sites. Frequent content updates, CMS migrations, and external site removals constantly create broken link rot that requires ongoing remediation.
