How to Move WordPress to HTTPS - in Simple, Easy-to-Understand Steps
https://www.wealthydragon.com/move-wo...
If your WordPress website is currently running on HTTP you may want to consider moving it to HTTPS for more security, better search engine rankings and better performance.
If you're planning on setting up a shop on your WordPress website the site will have to have an SSL certificate and an HTTPS connection. No payment gateway will work with you if you don't.
Apart from that, HTTPS based websites now rank higher in the search results than an HTTP equivalent so you can benefit from secure transactions, higher search engine rankings and better performance.
This video covers the basic steps on moving a WordPress website to HTTPS, but there is an extra step you will need to go through if you are using Cloudflare or a similar service - that step is set out on the page I linked to above.
The code snippets I referred to in the video are also available on that page.
Please let me know if I need to clarify anything.
Cheers,
Martin.
