About url shortener / expander
A short link is easier to share in messages and print. An expander does the reverse and shows where a short link really leads, which is useful before you click.
Safety
- Shortened links hide the destination. Expand unfamiliar links first.
- Be cautious with links asking for logins or payments.
Permanence
A short link only works while the service that created it runs. For important material, use your own domain.
A worked example
A link from a text message such as a short address can be expanded to reveal that it ends at a delivery-tracking page, a payment page or something unexpected. Seeing the final destination before you click lets you spot phishing attempts.
Staying safe
- Do not enter passwords or card numbers after following an unexpected link.
- Check that the domain in the address bar is the real company's.
- Be careful with links that create urgency, such as 'pay now or your account closes'.
