Agents search like buyers of a service contract. Coverage hours, response times and what a maintenance visit includes are their words, and pages written in them reach somebody managing a portfolio rather than a single building.
Breakdowns produce panicked, specific searching. Somebody in a building with a stopped lift wants a telephone number that will be answered, and being findable at that moment often introduces a company to a building it does not yet serve.
Home lifts are a consumer purchase entirely. A family adapting a house for a parent asks about space, disruption, funding and whether a stairlift would do instead, which is nothing like a commercial enquiry.
Independence is a search in itself. Owners tied to the manufacturer that installed their lift look for somebody who will service another make, and saying so plainly captures a frustrated and profitable audience.
