About Link Checker
A free link checking tool built to help anyone scan URLs for phishing, malware, and security threats — instantly, without an account.
Our mission
Phishing attacks, malware distribution sites, and deceptive redirect chains are among the most common ways people get compromised online. Most people do not have access to enterprise security tools that would flag these threats automatically — and they should not need them.
Link Checker was built to close that gap. We provide a free, no-login link checking tool that anyone can use to verify a suspicious URL before clicking it. Whether you received a link in email, SMS, or social media — paste it in and get a multi-engine threat verdict in seconds.
For SEO professionals and webmasters, Link Checker also functions as a dofollow link checker tool, redirect chain analyzer, and broken link detector — helping you audit the outbound links on your website without installing any software.
What our link checker scans
Phishing & malware detection
URLs are cross-checked against multiple threat intelligence engines to identify known phishing pages, malware distribution sites, and scam domains.
Domain age & reputation
Newly registered domains are a strong indicator of fraud. We surface domain age, IP location, ISP, and popularity score so you can assess context.
Redirect chain analysis
Our link redirection checker follows every HTTP 301/302 hop to reveal the true final destination of a URL — exposing cloaked or layered redirects.
Link attribute inspection
Verify whether a link is dofollow or nofollow by inspecting its rel attribute and HTTP headers — useful for SEO audits and link building campaigns.
Our principles
- Free, always
- Link Checker has been and will remain free to use. No premium tiers, no per-check fees. Checking external links should not cost money.
- No login, no data collection
- We do not require an account to use the tool. We do not store submitted URLs. Your scan history belongs to you — we never see it.
- Transparent results
- We show you which threat engines flagged a URL and why, rather than hiding behind a black-box verdict. You can make an informed decision.
