Scout24.
The marketplace surface is browser-only by design.
Found & recommended by AI agents
Search-class agents touched the close in some runs; the full agent-fleet access profile lands in a later wave.
This page measures the commerce lane: can an agent find Scout24, and once it arrives, transact. Talent, after-sales, procurement, investor and press lanes run on different surfaces and are not yet measured.
Your brand isn't measured yet
What does an AI agent do with your website?
The same measurement as Scout24, free for your domain. Five agent classes, one real task, your score in 48 hours.
The browser is the access unlock. Marketplace lead-completion is real, but it does not belong in the brand ranking.
We asked five kinds of AI agent to find a 3-room rental in Munich under €1,500 cold on ImmobilienScout24 (the same unbranded probe as Vonovia). A plain HTTP fetch returned the 'Ich bin kein Roboter' challenge page; the coding agent hit the same wall. Standard browser runs succeeded 3 of 3, preserving the Munich + 3-rooms + ≤€1,500 filter set and a results page with 252 qualifying listings. The autonomous agent reached the marketplace lead form on a qualifying expose (basic contact fields visible plus the 'Abschicken' submit button). Three of five agent classes reached the lead form; the surface is browser-gated by design.
One label, many breeds. From a plain reader to an autonomous operator, the kinds behind ChatGPT, Perplexity, and Claude Code:
Blocked somewhere on the path: Plain reader, Coding agent. A customer whose assistant runs on one of those breeds never finishes the task.
Scope. This is one filter set in one city. Scout24 lists hundreds of thousands of rentals and sales across Germany; the marketplace surface behaves similarly across them.
Found, and able to transact?
Two questions, measured separately. A brand can be recommended and still un-buyable, or perfectly buyable and never found.
When someone asks an agent to find a Munich rental, does it route to Scout24?
Scout24 comes up about a third of the time. The rest of the time, an agent recommends an alternative first.
Discoverability · 18-datapoint auditOnce an agent is on Scout24's site, can it submit a lead inquiry?
Search-class agents surface lead-ready in some runs; the full agent-fleet access profile lands in a later wave.
Evidence · 70 / 100 A measure of how provable and consistent the result is, grounded in cross-method ground-truth agreement (the methods that ran returned the same price), not a separate measured run. A confidence layer on the two scores above, not a third sales axis.
What this means for Scout24.
Scout24 is the marketplace counterpart in this measurement, not a brand-owned surface. On product discovery, the browser is the access unlock: the captcha turns away HTTP and a coding agent, but every browser-class agent reaches the lead form. The honest classification here is "marketplace lead-ready, browser-only path", and the right place to render that is a separate marketplace lane, not blended into the brand ranking.
Marketplace lane mechanics, not brand-surface repair. A separate marketplace render section that names Scout24 alongside Immowelt and Kleinanzeigen for the discovery question, a browser-readable lead-form contract that holds across the marketplace path, and citeable evidence so an answer engine surfaces the marketplace alongside the landlord on the same query.
The proof here is not more listings. It is the marketplace and the landlord appearing on the same query without competing for the same rank slot, re-measured each wave.

Rental marketplaces like Immowelt and Kleinanzeigen capture 72% of rental marketplace demand before Scout24.
Scout24 IS the intermediary in the rental category — the question is which intermediaries surface alongside it. Across the 18 Gate-1 responses, 72% named a competing portal (Immowelt in 13, Kleinanzeigen in 12, wg-gesucht in 10); ImmoScout24 itself appeared in 4 of 18 (22%). The Vonovia + Scout24 identical informational probe measures the landlord-vs-portal contrast on a single query: even on the marketplace side, the field is crowded — Scout24 does not own its category.

ImmoScout24 — 3-Zimmer-Mietwohnung Munich (marketplace lead)
- Close state
- lead-ready
- Bottleneck
- HTTP and coding agent blocked at the 'Ich bin kein Roboter' captcha; standard browser 3/3 preserves the filtered search; autonomous agent reaches the marketplace lead form end to end. Three of five agent classes reach the lead form; the surface is browser-gated by design. Marketplace lane, not brand ranking.
Fairness note
Wave 3 Slow Lane (a fleet wave Real Estate, marketplace subject). Single measured task (3-Zimmer-Mietwohnung Munich, ≤€1.500 kalt, lead_ready close state via marketplace lead form). Same unbranded informational probe as Vonovia by design. AI Visibility 37.22 (18/18 valid datapoints across 3 providers); AI Usability derived from a fleet wave per-breed access profile (HTTP + coding blocked at captcha; standard browser 3/3 holds the filtered search; autonomous agent opens the marketplace lead form). Channel split grounded via channel-derive.py (competing portals mentioned in 13/18 Gate-1 responses, ImmoScout24 own-domain in 4/18). Confidence C; classified as marketplace per Resolver C3, never blended into the brand ranking.
How the score was produced.
Discoverability is audit-pipeline-derived. 3-provider sample (openai, perplexity, anthropic), 3 query variants per task, 2 runs per variant · 18 valid datapoints scored against a five-state handoff cascade. [S1]
AI Usability is derived from the access-profile above (usability-derivation/v1): how far the best agent reached (close state) modulated by how many agent classes succeeded. The per-class profile is the truth; the score is a reproducible summary of it, not a separate rating. Fleet phases (HTTP / Coding / Browser / ACT) produce the profile. [S2]
Agent Success Score = (AI Visibility × 0.20) + (AI Usability × 0.70) + (Evidence × 0.10)
On a 0–100 scale, displayed 0–10. AI Usability bundles the agent's reach + completion; AI Visibility is audit-derived discoverability. Weighting is public; the per-prompt derivation is not.
Measurement scope
Confidence C · one measured task on a 3-provider track (openai, perplexity, anthropic). Confidence promotes to B with a second task plus a fourth provider on the next wave.
