Hello,
Thank you for contacting Rank Math support today and bringing your concern to our attention.
1. If you are planning on adding more than 500 websites, we may be able to create a custom plan for you. Just reach out to our support email so we can discuss it with you: s******@r***********
2. Our plugin doesn’t make use of a license key when adding a website to your account, instead, you only need to make a connection between the installed plugin to your RankMath.com account. You may refer to more about it here: https://rankmath.com/kb/rank-math-pro-license-key/
3. Unfortunately, we have no immediate plan on integrating with MainWP at the moment.
Hope that helps and please do not hesitate to let us know if you need my assistance with anything else.
