Transitioning site to “Enable SSL on all pages”. What are the steps to follow?

[papagino]

Hey folks, the sales on my shop www.miraxsupplements.com have drop considerably since January 2017 and I am wondering if this is related to Google now favoring full secure site and Chrome now showing “Your connection to this site is not secure, You should not enter any sensitive information on this site (for example passwords or credit cards), because it could be stolen by attackers…” when clicking on the icon next to the web address.

 

I am presently using the default SSL for pages that on my shop that requires it ex: Contact page, Connexion page… but is considering using the Enable SSL on all pages” feature of Prestashop.

My shop uses a premium theme and a few paid modules for shipping, SEO enhancements, Cache Manager, Blog and a few others.

 

I would like to know, what will be the impact on my site when I enable the “Enable SSL on all pages” feature and what I should do prior to unable this option. What will happen to all the back links from other sites linking to my site via the http vs the https site? Will the links automatically redirect to the new https links or do I have to setup a redirect on my Host? I assume that I will lose all the Social sharing likes to my site, is this the case?

 

I am aware that I will have to modify the links on Google Webmaster Tools & Analytics to assure the new links are being indexed, but other than that, what should I do?

 

Will this impact my page rank on the short term / long term?

 

Any thought or suggestions would be appreciated.

Cheers
Dan
