Search engines spend a fixed budget crawling your site. Links into 404s waste it, and a page full of dead links reads as neglected content.

Why broken links cost you
A dead link in the middle of an article is the most common reason a reader abandons a page. Outbound links rot silently as other sites restructure.
A link that returns 301 still works but costs an extra round trip. Updating the link to point at the final destination is free performance.
Frequently asked questions
How many links are checked?
Up to 100 unique links per scan. Every anchor href on the page is collected, normalised to an absolute URL and deduplicated before checking, so a page with repeated navigation links uses far less of that budget than it appears.
What counts as broken?
Any link returning a 4xx or 5xx status, plus links that time out or fail to connect. Links returning 3xx redirects are flagged separately as working but worth updating.
Why do some working links show as broken?
Some sites block automated requests by user agent, rate-limit rapid requests, or require a login. LinkedIn, Facebook and Cloudflare-protected sites commonly return 403 or 999 to any non-browser request even though the link works fine for a human. Verify anything surprising by hand.
Does it crawl my whole site?
No. It scans the links found on the single page you submit. To cover a site, run it against your most important pages, or against your sitemap pages one at a time.
Can I export the results?
Yes. Once a scan finishes you can download the complete result table as a CSV file for tracking or sharing.
