An SSL Certificate is a small data file installed on a web server that encrypts the connection between a visitor's browser and your website protecting any information exchanged, like passwords or payment details, from being intercepted.
Look for the padlock icon next to your website's address, and confirm the URL starts with 'https://' rather than plain 'http://' — the added 's' stands for secure.
