What Makes a Link Suspicious?
Learn the link patterns and context clues that make URLs worth checking before you click.
Suspicion usually comes from patterns
A suspicious link may use a strange domain, a misspelled brand, a raw IP address, deep subdomains, or a redirect chain that changes the destination.
Context matters too. A normal-looking link can be suspicious if it arrives unexpectedly or asks for sensitive information.
Domain mismatch
If the sender claims to be a known company but the final domain is unrelated, pause. Attackers can put brand names in paths, subdomains, or tracking labels while still controlling a different domain.
Unusual encoding
Punycode and other encoding patterns can hide characters that look familiar. This is why the technical form of a domain can matter as much as how it appears visually.
Risky requests
Links that ask for passwords, payment changes, MFA codes, or downloads deserve extra caution. The risk is not only the click; it is what the page asks you to do next.
What CheckLink checks
CheckLink estimates risk using available URL and domain signals. It can help you decide whether to proceed, verify elsewhere, or request manual review.
