Hello,
Thank you for getting in touch with us.
To add Rank math to another site, all you need to do is install the plugin on the site then connect to your existing account in Rank math > Dashboard under help tab.
If you wish to upgrade from free version to Pro version, you only need to purchase your package or if you already have an existing Pro account, just follow this guide: https://youtu.be/VRhdayGDBRA
