A person who wakes with severe back pain may search for a nearby physiotherapy clinic from a phone.
If the page loads slowly or the booking option is buried, that person can leave before finding out whether the clinic is suitable.
A useful site answers the immediate questions quickly: who do you treat, where are you located, what does an appointment involve, and how can I get in touch?
The design should also set an appropriate tone for healthcare.
Clear spacing, calm colours, readable text, and straightforward language can make the practice feel organised before a patient arrives.
