A Selection of Articles Related to Switching From http to https
If your website is using http and you want to use https, there are some very important steps you want to take.
All your pages are currently listed as http in the search engines. If you switch to https and someone clicks on a search engine listing to your page, they will get a 404-page error or Page not found. You need to redirect everything from http to https.
If you find the techniques out of your comfort zone, you can contact support for help. You need your web host to install the SSL certificate anyway, so they may help you with the redirect.
I have listed a few articles below that will help you make the switch from http to https quick and painless.
Have a look at the tips these articles have to offer.
