How to make HTTP and HTTPS versions of the site available
In some situations, the user may discover that the HTTPS version of the site is not supported on their device when accessing it from Yandex search results. For example, the HTTPS version may be using a certificate from the National Certification Center, while the user’s device does not support it. In this case, Yandex may suggest that the user switch to the version of the site available via HTTP instead of HTTPS. To make sure this happens, check the conditions:
- The HTTPS version is the main address of the site.
- The HTTP version is available to users and the Yandex bot — check the server response. If necessary, remove the redirect from the HTTP version to the HTTPS one.
- The contents of the HTTP version are completely identical to the contents of the HTTPS version.
