Frequently asked questions about the website link checker
A link checker is a tool that analyzes a URL before you visit it. When you paste a link, our tool scans it against threat intelligence databases, checks the domain's reputation, inspects redirect chains, and looks for known patterns of phishing, malware, and scams.
We check for a wide range of threats, including phishing pages, malware distribution sites, scam websites, deceptive redirects, typosquatted domains (sites impersonating legitimate brands), and domains that have been recently registered or flagged by security researchers.
Absolutely. If you've received a suspicious link from any source; an email, a text message, a DM, or a post, simply copy and paste it into the checker. You don't need to click it first.
Our tool cross-references multiple threat intelligence sources to maximize accuracy. No tool is 100% perfect, but we continuously update our detection methods to minimize both false positives (safe links flagged as dangerous) and false negatives (dangerous links that slip through).
Our threat database is updated in real time. New phishing sites and malware domains are being created constantly, and our data sources refresh continuously to keep pace with emerging threats.
We do not sell or share your submitted URLs with any third parties. URLs are not stored at all.
Yes, completely. Pasting a URL into our tool does not initiate any connection between your device and the destination site. We do the analysis on our end, so you stay protected throughout the process.
No. You can start checking links immediately without signing up. An account is only needed if you want to access premium features or track your scan history.
Most scans complete in under three seconds. Occasionally a scan may take a little longer if the URL involves complex redirect chains or requires deeper analysis.
This can happen if a site was previously compromised, shares infrastructure with a known bad actor, or was recently reported by users. If you believe a site has been incorrectly flagged, you can submit it for review and we'll investigate promptly.
Don't panic, but act quickly.Run a malware scan on your device, change passwords for any accounts you may have accessed recently, and monitor your accounts for unusual activity. If you entered any personal or financial information, contact the relevant institution immediately.
Yes. Every scan result includes a "Report this result" option. Our security team reviews submissions and updates ratings accordingly, usually within 24 hours.
