How is it different from a general website builder?
It is built around listings, enquiries and agents rather than adapted to them, and the connections to the portals and the CRM are the point.
A general website builder can produce a good-looking page, but it has no idea what a property is: your listings are something you paste in by hand and then update twice. Cloud holds listings and their photographs as listings. A Properties section shows them as cards, every published listing gets its own page with an enquiry form, and your website has a property search page. Booking a viewing from your website is still being built.
The larger difference is the ecosystem around it: the portals your buyers already search, Housing Market CRM where enquiries get worked, and market data from Housing Market Insights. Those products are live. The connections between them and a Cloud site are still being built, and that is the honest shape of the comparison today.
What you get today that a general builder does not give you: a site made for a real estate business, hosted and kept running by the company whose portals your market already uses, in seventeen languages, at no cost to start.
