Real estate agent website in Austria: what it needs to win owners, not just clicks

Short answer: a real estate agent website in Austria pays off when it does one job the portals can't: winning owners who want to sell or let. That takes three things: your broker software (usually Justimmo) feeding listings in automatically, a separate route for sellers with a valuation request, and pages fast and clear enough that Google and ChatGPT name your office. A typical build takes 8 to 12 weeks.

Most agency websites we see in Austria are digital business cards. They show the logo, the team photo and a property list that someone updates by hand twice a month. Buyers still find the listings on willhaben or ImmoScout24, and owners who want to sell compare five agencies side by side on the same portal.

We have built real estate sites for agents, developers and investment companies, including Hyatt Immobilien, Wolf & Sohn, LANDAA and Stoisser Immobilien Holding. This article is what we have learned about which parts actually bring enquiries and which are decoration.

Why do you need your own website if you're on willhaben and ImmoScout24?

Portals are where buyers and tenants search. That will not change, and you should stay there. But on the portal you are one listing among hundreds, next to your competitors, on terms the portal sets. The buyer remembers the flat, not the agent.

Your business, though, depends on mandates, and mandates come from owners. An owner who wants to sell a flat in the 19th district doesn't browse listings. They search for "Immobilienmakler Döbling", ask friends, or ask ChatGPT which agents are good. Whatever they find then decides whether you get the call. That is the job of your own website.

So the question is not portal or website. It is: what does your website do that the portal doesn't? If the answer is "show the same listings again", the site will not change much.

How does the listing feed from Justimmo or onOffice work?

Most Austrian agencies manage their properties in broker software: Justimmo is very common here, along with onOffice, EDI-Real and others. The rule for the website is simple: you enter a property once, in the software, and it appears on the website without anyone copying anything.

Technically, there are three common ways to do this:

• API connection: the website pulls listings from the software's interface. Justimmo and onOffice both offer APIs. This gives you full control over design, search filters and detail pages, and enquiries can flow back into the software.
• OpenImmo export: the software sends an XML file in the German-speaking standard format, and the website imports it. Works with almost every system, but updates arrive in batches rather than instantly.
• Embedded modules or iframes: the software provides a ready-made search and detail view that sits inside your site. Quick to set up, but it often looks foreign and is weaker for SEO.

For Hyatt Immobilien the core task was to embed the Justimmo property search and detail views cleanly and design a modern layout around them, so the software feels like part of the brand. For Wolf & Sohn in Vienna we built a fully automated Justimmo interface for real-time data and added 3D renderings and virtual tours to the property pages. Wolfgang Sztatecsny from Wolf & Sohn put it this way: "Every integration, like Justimmo and other platforms, runs absolutely smoothly."

If you use EDI-Real or another system, check two things before the project starts: does the software have an API or an OpenImmo export, and does your licence include it? Some providers charge separately for interface access.

How do you get more owners instead of only buyers?

Buyers find you anyway, through portals. Sellers you have to win. That is why the most important page on an agent's website is usually not the home page but the seller page: a separate route for owners, with its own entry point in the menu and its own campaigns pointing at it.

What belongs on it:

• Valuation request: a short form (property type, location, size, condition, timeline) that an owner can fill in within two minutes. Keep it short; ask the rest on the phone.
• District figures: what flats and houses in the area have recently sold for, how long sales took. This shows you know the market and gives owners a reason to stay.
• Appointment booking without a phone call: many owners research in the evening. Let them book a slot for a viewing or a consultation straight away.
• References from sellers, not just buyers: sold properties, short quotes, the process from mandate to signing.
• A clear next step on every page: first trust, then the call to action. Not five buttons with different wording.

One honest note on automatic online valuations: an instant price calculator generates many entries, but also many low-quality ones. We prefer a valuation request that leads to a personal assessment. Fewer leads, better conversations.

What makes a good property page?

The property detail page is where buyers decide whether to enquire. It is also the page most often neglected, because it comes "out of the software". It is worth designing properly:

• The first photo decides. Large, well-lit images first, floor plan close behind. Optional video, 360° tour or drone shots for premium objects.
• Key facts at a glance: price, size, rooms, location, operating costs, energy certificate (HWB and fGEE values are mandatory in Austrian property advertising under the Energieausweis-Vorlage-Gesetz).
• Enquiry form directly on the page, with the property already filled in, so the right person in your team gets it with a clear status.
• Search alert and saved list, so a buyer who missed this flat gets the next suitable one by email instead of going back to the portal.
• Financing calculator where it helps: it sorts out early who can afford the object.

For Property Partners, which rents furnished apartments in Vienna, on the Semmering and in Wiener Neustadt, the whole site is built around a clear search (location, dates, guests) and well-structured detail pages that make the benefit of booking direct visible straight away.

Why does speed matter so much on real estate sites?

Property sites are image-heavy: dozens of photos per listing, galleries, sometimes tours. Done badly, a listing page takes five seconds or more to load on a phone, and most visitors come from phones, often from a portal or an Instagram ad.

Google measures this with the Core Web Vitals. A page counts as good when the main content appears within 2.5 seconds (LCP), the page reacts to taps within 200 milliseconds (INP) and nothing jumps around while loading (CLS under 0.1). For property sites that mainly means modern image formats, images sized to the screen, and galleries that only load what is actually shown.

Iframe-embedded listing modules are a common speed and SEO problem: the content often isn't visible to Google as part of your site at all. With an API connection, every listing becomes a real page on your domain that can rank.

How do owners find you on Google and in ChatGPT?

Owners search locally: "Immobilienmakler Wien 1090", "Wohnung verkaufen Graz", "Makler Mödling". For these searches three things count:

1. Google Business Profile: complete, with the right category, opening hours, photos and regular reviews. This decides whether you appear in the map results.
2. District or location pages: one page per area you really serve, with real content (recent sales, typical prices, your local team), not the same text with a different place name.
3. Structured data: company, location, contact and listing data stored in a machine-readable way (schema.org), so search engines and AI tools understand who you are and where you work.

The last point is becoming more important. More and more people ask ChatGPT or Perplexity "which agent in Vienna is good for selling a flat?" and get three to five names. Whether your office is among them depends on how clearly your site and other sources describe you.

Brand or catalogue: what should the site look like?

Many agency sites in a region look interchangeable: a header photo of a skyline, a search bar, three icons. Owners hiring an agent are choosing a person they trust with a large asset. The site should show who you are: the team, your approach, your area, sold properties.

Different businesses need different sites. For Wolf & Sohn we developed the whole brand from scratch, from the logo to the interface. For Stoisser Immobilien Holding, an investor rather than an agent, the brief was the opposite: a strongly reduced digital business card that puts acquisition profiles and track record first, with no listing search at all. 16EAST needed a brand and portfolio site for acquisition, development and realisation.

What does a real estate agent website cost?

It depends on scope more than on the number of pages. A digital business card with an embedded listing module is a different project from a site with an API connection, owner route, search alerts and location pages. These are the main cost drivers:

We don't sell standard packages; you get a fixed quote after a free analysis. Ask about funding too: the federal digitalisation funding has ended, but regional programmes may fit; we check that in the strategy call. Status and alternatives: our funding article.

When is a bigger website not worth it?

Not every agent needs a full build. Be honest with yourself:

• You work almost only through referrals and have more mandates than you can handle: a clean, fast business card with good references is enough.
• You have a handful of listings a year: an API connection with search alerts won't pay off. A simple object page per project is better.
• Nobody in the team will follow up enquiries quickly: a website that generates owner leads only helps if someone calls back the same day.
• You plan to switch broker software soon: decide on the software first, then build the integration once.

And if the current site is basically fine, sometimes SEO, tracking and a proper seller page bring more than a complete relaunch.
