Mini Lesson

Just as you would check that a street is safe before crossing it, you should check that a website is safe before using it. The good news is there are clear signs to look for — and just as clear warning signs to watch out for!

Signs of a SAFE website

  • Padlock icon in the address bar — the small lock symbol means the connection between your device and the website is encrypted (scrambled for security).
  • HTTPS at the start of the web address (not just HTTP) — the "S" stands for Secure.
  • Approved by a trusted adult — your parent or another grown-up has checked it.
  • Clear contact information and an "About" page that explains who runs the site.
  • No pop-up windows demanding personal information or offering prizes.
  • Age-appropriate content — the website is designed for children or families.

Warning signs of an UNSAFE website

  • No padlock / HTTP only — connection is not secured.
  • Pop-ups that won’t close — especially ones that say "You’ve won!" or "Click here!"
  • Asks for personal information — name, address, phone number, or payment details.
  • Lots of flashing ads and buttons that look like fake download buttons.
  • Spelling mistakes in the web address (e.g., "gooogle.com") — this is called a phishing site that tries to trick you.
  • Scary warnings or messages that claim your device is broken and you must click immediately.

What to do if you land on an unsafe-looking site

  • Close the tab immediately — do not click anything on the page.
  • Tell a trusted adult what happened.
  • Never enter any information into a website you are unsure about.
