This is where your booking app opens
You tapped Book on a sample site. The business is made up, so there is nothing to book.
On your own bizhq site, this button opens the booking page you already use, such as Square Appointments, Booksy, Vagaro, Calendly, Acuity, Fresha or GlossGenius. Paste your link under Booking & reviews in the editor, and every Book button on your site uses it.
No booking app? Leave it out. Customers can still call, text or send you a message through your contact form.
