A while ago Google advised that one of the ranking factors it would consider in a websites page rank was secure hosting.
This means your website address starts with https rather than just http.
So what is it and why?
Google said in a recent article :
"You should always protect all of your websites with HTTPS, even if they don’t handle sensitive communications. Aside from providing critical security and data integrity for both your websites and your users' personal information, HTTPS is a requirement for many new browser features.
"HTTPS helps prevent intruders from tampering with the communications between your websites and your users’ browsers. Intruders include intentionally malicious attackers, and legitimate but intrusive companies, such as ISPs or hotels that inject ads into pages."
So I've been talking to clients and have a gradual programme of moving all websites to secure hosting, you'll see a security padlock in your browser when it's done.
Good for security, helps with SEO.
