Do my Google reviews come into the Hub?

Not yet. The Hub is not connected to your Google profile:

• It does not fetch reviews from Google or other platforms.
• The interface currently has no button for entering a Google review by hand.
• It publishes nothing on Google.

What the Hub collects are the answers to your own request after the visit, see Asking for a review after the visit. With the Link to your review page you lead guests to your Google profile.

If a review in the stack is marked as a Google review, the Hub helps you reply, see Replying to reviews.
