This blog's domain (onlinepinoy.net) has been running for 2 years now. It had the regular http URL with no SSL certificate.
Just recently I discovered that there is a free SSL certificate offered by Google/Blogger. This is a good update since having https in your URL increases website credibility and organic rankings.
Here are the steps to turn on the https in your domain:
Go to Settings then Basic then select Yes to the https options just like below.
Now, my URL is appearing as secure: https://www.onlinepinoy.net/. Your website rankings might be affected for now but don't worry everything will go back or even better, increase.
Tip: Don't forget to update Google Search Console and Analytics using the new URL with https.
