Activate SSL (HTTPS) for Blogger Custom Domains
Blogger has enabled secure browsing of blogs which are hosted at a custom domain - i.e. not at blogspot.com. As Google themselves say here : It helps check that your visitors open the correct website and aren’t being redirected to a malicious site. It helps detect if an attacker tries to change any data sent from Blogger to the visitor. It adds security measures that make it harder for other people to listen to your visitors’ conversations, track their activities, or steal their information. Importantly, Google is taking steps to give priority to HTTPS websites in search results . Furthermore, by July 2018, the Chrome browser will highlight HTTP websites as "Not Secure" . The change is quick and easy, and will not result in any downtime for your blog. Existing links will continue to work, and can be automatically redirected to the secure pages.
