Broken Link Checker
Find dead links (404s) on any page. Free, no signup.
>
Broken links quietly erode trust, waste crawl budget, and send visitors into dead ends. This broken link checker requests every link on the page you give it and reports the ones that fail — 404s, server errors, and timeouts — so you can fix or redirect them before they cost you rankings or readers. Paste a URL and scan; no signup, no install.
How it works
- 01
Enter a page URL
Paste the address of the page you want to audit — a landing page, article, or link-heavy resource.
- 02
Scan the links
Sitewell extracts every link on the page and requests each one to see whether it responds successfully.
- 03
Fix the failures
Review the list of broken links with their status codes, then update or redirect each one and re-scan.
Frequently asked questions
- What counts as a broken link?
- A broken link is any link whose target returns an error instead of loading — most often a 404 (not found) or a 5xx server error, but also connection timeouts and DNS failures. Sitewell tests each link on the page and flags every one that does not respond OK.
- Why do broken links hurt my site?
- Dead links frustrate visitors, leak crawl budget, and signal a poorly maintained site to search engines. Broken outbound links can also drag down perceived content quality, while broken internal links strand pages that should be passing authority.
- Does this scan my whole site or one page?
- This tool checks every link found on the single page you submit, which is ideal for spot-checking a key landing page, a blog post, or a resource list. To watch a page over time, save it as a monitor and Sitewell will re-scan it on a schedule.
- How do I fix a broken link once I find it?
- For internal links, update the URL to the correct page or add a 301 redirect from the old address. For broken outbound links, point to an archived copy, find a current equivalent, or remove the link. Re-run the scan afterward to confirm the fix.
