How to Know If a Link Is Safe Before Opening It
A simple guide to checking suspicious links, reading domains, spotting redirects, and avoiding fake login pages.
## Why checking links matters
Most phishing attacks start with a link. The page may look normal, but the domain,
redirect chain, or request for personal information can reveal the real risk.
## Start with the domain
Look at the real domain before you trust the page. Attackers often use domains
that look close to a familiar brand, add extra words, or hide the brand inside a
long subdomain.
For example, secure-paypal.example.com is controlled by example.com, not PayPal.
## Watch for redirects
A redirect is not always bad, but several redirects can hide the final destination.
If a link jumps through shorteners, tracking domains, and unknown websites, treat
it carefully.
## Check for HTTPS
HTTPS is important, but it does not prove a site is safe. A phishing site can also
use HTTPS. Think of HTTPS as one signal, not a full safety guarantee.
## Red flags before clicking
- The sender pressures you to act fast
- The domain is misspelled or unfamiliar
- The link goes to a login page you did not request
- The message promises a prize, refund, or account warning
- The final domain is different from what you expected
## Bottom line
Before opening a link, check the destination, domain, and redirect behavior. A few
seconds of checking can prevent account theft, malware, and payment scams.
