Local Book Online CTA For Call Business
Google seems to be testing a new option for the Book Online call to action option that does not use an online booking service but rather lets you call the business directly.
Rather than directing users to book a reservation to a restaurant through third party vendors, Google has been testing out call to action buttons that pull up the restaurant phone number, allowing users to call directly to book a table. It is yet to be see whether or not Google implements this to more users, but this is a promising test to give more direct access to owners of restaurants.
