01What the website must do
- Listings with address, price, area and energy class — the energy certificate data are mandatory in sale and rental listings (Building Code § 67).
- Agent pages: who is responsible for which property and how to contact them.
- Enquiry flow: an enquiry about a listing reaches that listing's agent, not a general inbox.
- Connection to portals: the same property should not be updated by hand in several places.
- Findability in search: a sitemap that Google reads (Google: sitemap), and Search Console, where you see whether pages are indexed (URL Inspection).

02Ways to build it and the costs
There are three options: a ready-made site builder (SaaS), WordPress with a developer, or an agency page provided by a portal. The prices below are from the providers' own price lists; there is no public price source for a developer's work, so none is given here.
| Service | Plans | Price per month | Own domain |
|---|---|---|---|
| Squarespace | Basic, Core, Advanced | €11–29 billed annually; €15–42 billed monthly | 1 year of free registration with an annual plan |
| WordPress.com | Personal, Premium, Business, Commerce | US$4–45 billed annually; US$9–70 billed monthly (excluding taxes) | 1 year free with an annual plan; not with a monthly plan |

03What to check before paying
- The domain is registered in the agency's name, not the developer's or the provider's.
- If the same listing is both on a portal and on the agency site, a canonical tag tells Google which URL is the original (Google: canonical). Check that you can set it.
- Listing and enquiry data can be exported if you change provider.
- The site has a sitemap and it can be submitted in Search Console (Google: sitemap).
04Order of work
- the domain in the agency's name;
- template or builder, and the agent pages;
- listing import and the enquiry flow;
- Search Console, submitting the sitemap and checking the first URLs (URL Inspection).
