The reason to add a second page is never that the first one felt too long. It is that something on it deserves an address of its own. A menu, a service, a location: each is a separate thing people search for by name, and a search engine can only send somebody to a page, never to the middle of one. The four builds here are that shape in practice: a menu, two service lists, and a sign portfolio that runs to four pages and lets its owner add work to it.
Every page gets its own title, its own description and its own address, which sounds like housekeeping and is the difference between two pages helping each other and two pages competing for the same search. Your details are written once and read everywhere they appear, so a phone number cannot be right on one page and wrong on another. Pages can be added later without rebuilding anything.
