The final switch to "mobile-first" by March 2021 continues to be a source of concern. Recently, a Twitter user asked John Müller from Google whether one's own canonical tags would also have to be adjusted as part of the switch.
If a website consists of a separate mobile and a desktop version, it is advisable to set canonical tags so that both versions are not indexed next to each other. Canonical tags usually point to the desktop rcs data uae version because in the past this was often the main version of a website. Müller reassured the inquirer and replied that it was not necessary to change the canonical tags so that they point to the mobile version.
If your website is divided into two versions - one for mobile users and one for the desktop - you should use canonical tags to avoid indexing both versions. Otherwise, duplicate content would be created.
It is important that both pages have largely the same content. A "stripped down" mobile page that only contains a fraction of the content of the desktop version is not suitable for a canonical tag. Put simply, it is important that the content is identical or almost identical. The ideal way to offer a website is with responsive design. This means that there is only one version of the website that automatically adapts to the screen width of the device or browse
