HTTP vs HTTPS
Google are now prioritising HTTPS websites over HTTP websites:
Hyper Text Transfer Protocol Secure (HTTPS) is the secure version of HTTP, the protocol over which data is sent between your browser and the website that you have visited. The ‘S’ at the end simply stands for ‘Secure’.
By making your website HTTPS it means all communications between your browser and the website are encrypted. HTTPS can be used on all websites to make them more secure, but is vital to have a HTTPS when there is highly confidential information being inputted, such as on online shopping order forms. Sometimes a padlock showed in the user browser address bar can symbolise that the website is HTTPS.
