A hospital is not just a bigger clinic. It has many departments, many doctors and many treatments, and patients search for each of them separately. Somebody looking for a knee replacement and somebody looking for a maternity ward type very different things in Google, so one Google listing and one home page cannot bring both of them.
So for hospitals we start with the basics done department-wise. A proper page for each department and each senior doctor on the website, the hospital's Google profile and the doctors' profiles set up correctly, and ads only for those departments where OPD slots or beds are going empty. Reviews are also handled carefully, because one bad experience at the billing counter should not decide how people see your surgeons.
