https for your gym's website

First, the entire online booking system is 100% secured by HTTPS.

For those gyms that choose to embed the online widgets, the embedded portion on their web page is of couse secure.

But if the hosting web page is not HTTPS, then customers will see the HTTP in their browser and may be confused. The information in the booking system is secure, but customers will not be able to tell because of the HTTP from your web page.

This is not a limitation of RGP. This is the way browsers work. Bookeo, etc. all behave identically.

Additionally, Google is now ranking pages that use HTTPS as higher in their search.

Thus - it is highly recommended that you serve your gym's website over HTTPS. The days of HTTP (insecure web pages) being a valid protocol are behind us! :)
