We manage 300+ client websites. We need one project per client, each connected to a different Google Business Profile, with a unique embed code so new reviews automatically appear without manually updating the website.

Could you confirm:

1. Which tier supports 300+ active projects, Google Business Profiles and published widgets?
2. Can all widgets remain active simultaneously?
3. Are there limits on websites, widgets, monthly views, synced reviews or Google connections?
4. How frequently are new Google reviews synchronized?
5. Can we connect using a public Google Business Profile URL, or must each client authorize through Google OAuth?

We want to confirm the required tier and scalability before implementation.
