Broken Link Checker —
Detect & Fix Dead URLs Instantly
Detect broken links on any website and improve SEO performance by fixing dead URLs.
What is a Broken Link Checker?
A broken link checker is an SEO tool that scans a website to identify links that no longer work, also known as dead links or 404 errors. These broken links can negatively impact user experience and reduce a website's performance in search engines.
Broken links often appear when pages are deleted, URLs are changed, or external websites go offline. Over time, they can weaken your SEO strategy and reduce the effectiveness of your backlinks.
Using a broken link checker helps you:
- Identify broken internal and external links
- Improve user experience and site navigation
- Maintain a healthy link building structure
- Protect your domain authority from decay
Fixing broken links is also an important opportunity for link building. Many SEO professionals use a strategy called "broken link building," where they replace dead links on other websites with their own relevant content.
This method is highly effective because it provides value to both parties: website owners fix their broken links, and you gain a high-quality backlink.
To scale this process, marketers often use a link building marketplace to find replacement opportunities faster. You can also rely on professional link building services to identify and replace broken links at scale.
Regular audits using a broken link checker ensure your website remains healthy, user-friendly, and optimized for search engines.
How Broken Link Checker fits into a working SEO process
Broken links silently damage user experience, crawl efficiency, and link equity flow. A broken link checker scans any page or full site and surfaces 404s, 500s, and dead external links — the basis for both technical cleanup and broken-link-building outreach.
When SEO teams reach for this tool
- Quarterly site-wide audits to catch and fix 404s before users do
- Broken link building: finding dead pages competitors link to and suggesting your content as a replacement
- Post-migration checks to verify redirects caught every broken path
- Outbound link hygiene on long-standing editorial pages
Turning results into ranking gains
Broken-link building remains one of the highest-conversion outreach tactics. Webmasters appreciate the heads-up, and they're far more likely to add your link in exchange. A single tool scan can surface 30-50 prospects from a target domain.
Broken links — your questions answered
A broken link is a hyperlink that leads to a page that no longer exists, has been moved, or cannot be accessed — typically returning a 404 or 410 error. They disrupt user experience and signal poor site maintenance to search engines.
Broken links harm user experience by leading visitors to dead ends, which increases bounce rate and reduces engagement. They also prevent search engine crawlers from properly indexing your pages, and can cause loss of link equity if important backlinks point to non-existent pages.
You can fix broken links by updating the URL to a valid page, setting up a 301 redirect from the broken URL to a relevant live page, or simply removing the link if no suitable replacement exists. Regular audits help catch these issues before they compound.
Broken link building is a proactive SEO strategy where you find broken links on other websites that point to dead resources, then reach out to the site owner suggesting your own relevant content as a replacement. It's effective because it provides value to both parties — you gain a backlink, they fix a broken link.
