How do you prepare a landing page or a booking link?

The link opens the booking or the message with the dish and the day already written, and it is tested on a phone. People are not sent to the home page if whoever taps has to search again for what was advertised. Open the link signed out and check that someone answers. The ad promises Thursday’s menu and the link lands on the general menu without that day. The tested link and the line the guest finds on opening it, the same as the ad.
