Hello,
Thank you for contacting the support.
If you are talking about PRO vs Business license then, You can use the Rank Math PRO on unlimited personal websites, and you can use the business plan on 100 client & personal websites. Personal websites are the ones you own 100% and not a client website or a partnership with someone. A personal website can be a business, earn you money and you can even sell it to anyone but it needs to belong to you.
In terms of features, you can check the following comparison:
