Owners of restaurants and cafes will be able to add new dishes from Search and Maps to their profile. They can also activate the online booking option through Search. To do this, you need to become a member of the Reserve with Google partner program.
Another update for service businesses is the ability to update online checkout options from Google Search. For example, restaurants will be able to indicate which options they provide: pickup or delivery.
Also, in the near future, business owners will be able to create and publish posts directly from Search.
To access the editing functionality, the business must log into the Google Account associated with the GMB profile and find the name of their organization.
Recall previously Google My Business added new metrics in the performance report.
