ImmobilienScout24 vs immowelt Germany | GPPI Independent Comparison
Quick Verdict
ImmobilienScout24 (IS24) is Germany's undisputed #1 property portal by every measurable public signal. With 102.8M monthly sessions (2024, Scout24 reporting), 19M monthly users (2025), 513,360 active listings, and a direct traffic share of approximately 60%, IS24 commands a structural moat that no German competitor has matched in the portal era. It is a Frankfurt-listed, MDAX-constituent public company generating €649.6M in revenue in 2025 with a 62.5% ooEBITDA margin — financial metrics that validate its network effects rather than merely describe them. Its 26,000 professional customers pay an average of €1,506.45 per month in total billings, the highest verified professional ARPU in the German market. immowelt is the flagship portal brand of AVIV Germany GmbH — the German operating unit of KKR/CPP-backed AVIV Group, Europe's largest classifieds network by portfolio. Founded in 1996 and predating IS24 by two years, immowelt has struggled to reclaim top-of-market position despite operating alongside sister brand immonet.de (now being sunset into immowelt). AVIV's strategy is consolidation: concentrating Germany's #2 portal family traffic into a single immowelt brand, investing in the estateSmart/estateOffice/estatePro CRM suite, and leveraging PE ownership to grow ARPU and operating leverage. Monthly visitor and active listing data are not publicly disclosed, which itself signals the performance gap to IS24. For agents and landlords seeking maximum reach in Germany's structurally tight rental and sales market — 52.8% renter households per Destatis 2024, undersupply in major cities, intense Mietpreisbremse compliance pressure — IS24 is the primary listing surface. Its HeyImmo AI assistant, AI image search, Sprengnetter-integrated valuation, and BauFi mortgage cross-sell represent the most advanced end-to-end product stack in German residential property. immowelt is the essential secondary complement, particularly for agents serving volume-rental segments, clients seeking network breadth across DACH, and smaller agencies for whom IS24's ARPU may strain budget. AVIV's immonet consolidation will temporarily concentrate traffic but creates short-term indexing risk. The strategic question is not 'IS24 or immowelt' — it is 'IS24 always, immowelt when budget and geography permit.'
Strategic verdict: ImmobilienScout24 vs immowelt in Germany
The comparison between ImmobilienScout24 and immowelt in Germany is ultimately one of market incumbency versus competitive positioning within a consolidating duopoly. IS24 has held the #1 position since the early 2000s, and its 2024/2025 public financials confirm that incumbency has compounded rather than eroded: €649.6M in group revenue, 62.5% ooEBITDA margin, and 102.8M monthly sessions place it in a category of one among German residential portals. Its 26,000 professional customers paying €1,506.45/month in total billings represent the deepest documented monetisation relationship between a German property portal and its agent base. immowelt's strategic story is one of PE-backed restructuring and consolidation. KKR and CPP Investments, the AVIV Group majority owners, have pursued a playbook common to European classifieds: reduce brand fragmentation, grow ARPU on the retained brand, and generate operating leverage through shared technology. The sunset of immonet.de into immowelt is the clearest expression of this: two brands competing for overlapping audiences is capital-inefficient; one brand with concentrated traffic is more defensible. Axel Springer's ~10% minority stake adds a media distribution dimension to immowelt's visibility strategy. For the German housing market's participants — agents, developers, landlords, and private searchers — the practical implication is that IS24 is non-optional as the primary portal surface. Its audience scale, listing depth, AI tooling, and integrated financial services (BauFi mortgage, Sprengnetter valuation) create switching costs that no secondary portal fully replicates. immowelt's role is as the essential complement: broader DACH network exposure, a lower ARPU entry point for smaller agencies, and a distribution surface that reaches renters and buyers who do not search on IS24 alone. The consolidation of immonet into immowelt, once complete, will strengthen immowelt's relative position but is unlikely to close the gap to IS24's session and inventory scale in the 2025–2027 planning horizon.
Where ImmobilienScout24 has a structural edge
IS24's structural advantages are reinforced by four interlocking factors that are difficult for any competitor to replicate quickly. First, audience scale: 102.8M monthly sessions and 19M monthly users (Scout24 reporting) create a supply-demand flywheel where agents list on IS24 because searchers are there, and searchers visit IS24 because agents list there. The ~60% direct traffic share confirms brand-first navigation, meaning IS24 captures intent before searchers even consider alternatives. Second, financial and product investment capacity: Scout24 SE's €649.6M revenue and 62.5% EBITDA margin fund a documented M&A and R&D programme — Sprengnetter (valuation data, 2023), neubau kompass (new development, 2024), bulwiengesa and EXPLOREAL (market intelligence, 2025) — that continuously deepens the platform's data moat. HeyImmo AI assistant, AI image search, and TensorFlow-based ranking/matching are deployed at scale, not in pilot. Third, agent monetisation depth: professional ARPU of €1,506.45/month is the highest verified figure in the German market. IS24's Propstack CRM, Realtor Lead Engine, and tiered private subscriptions (TenantPlus/BuyerPlus/LivingPlus) create revenue diversification that insulates it from any single product line's performance. Fourth, listing inventory: 513,360 verified active listings is the largest confirmed count in the German market, giving searchers a completeness argument that is very hard for immowelt to counter without disclosing its own figures.
Where immowelt changes the equation
immowelt's competitive relevance rests on three specific dimensions that make it a meaningful secondary portal rather than a marginal one. First, distribution network breadth: through its AVIV Group architecture, immowelt distributes listings across the immowelt platform, the legacy immonet network (during the wind-down period), and AVIV partner sites — providing a multi-surface distribution that IS24's single-brand model does not replicate. For landlords and agents managing high-volume rental books, this multi-surface reach adds incremental exposure that IS24 alone does not guarantee. Second, cost positioning: immowelt's directional ARPU of approximately €8,000/year (~€667/month) is meaningfully lower than IS24's €1,506.45/month total billing, which matters for smaller agencies, independent landlords, and property managers operating on tight cost structures in a market where rental yields are compressed by supply shortages and rent regulation. Third, the estateSmart/estateOffice/estatePro CRM suite represents a genuine professional tooling investment — immosolve, bauen.de for homebuilding content, and umzugspreisvergleich.de for moving comparison extend immowelt's service perimeter beyond pure listing classifieds into the adjacent lifecycle of a property transaction, giving agents reasons to engage with the platform beyond listing placement alone.
When to choose ImmobilienScout24, when to choose immowelt, and when to use both
The decision framework for agents and landlords in Germany is relatively clear given the available data. Choose ImmobilienScout24 as the mandatory primary portal for any professional operating in the German residential market: its audience scale, listing completeness, AI-enhanced product stack, and agent monetisation infrastructure make it the highest-ROI single portal investment. If budget permits only one portal, IS24 is the answer — its 102.8M monthly sessions and 513,360 listed properties represent a concentration of German housing search intent that no secondary portal matches. Choose immowelt as the essential secondary complement when: (a) the agent or landlord serves volume-rental segments where incremental DACH network exposure matters; (b) budget is constrained and IS24's ARPU is at or above the cost ceiling; (c) the portfolio spans Germany's mid-market cities where immowelt/immonet historically maintained strong local brand recognition; or (d) the professional already uses AVIV Group's CRM tools (estateSmart/estateOffice/estatePro) and seeks integrated workflow benefits. Use both portals when maximising listing reach across all German search surfaces is the primary objective — which is the case for most established agencies, large residential property managers, and developers marketing new schemes. The combined spend of IS24 (~€1,506/month) plus immowelt (~€667/month) totals approximately €2,173/month, a budget that most mid-size German agencies can justify given Germany's persistent rental demand and the recovery in sales transaction volume in 2024/2025. Monitor the immonet consolidation timeline: once complete, immowelt's audience concentration improves and may warrant an ARPU reassessment.
GPPI pillar implications for ImmobilienScout24 vs immowelt
Across all four GPPI pillars — Listing Quality, Discoverability, Market Experience, and Product Innovation — ImmobilienScout24 leads on the available public evidence. This is not a marginal advantage: IS24's lead on each pillar is grounded in verifiable data points (session volume, listing count, ARPU, documented AI deployments, M&A activity) that immowelt cannot match with publicly disclosed equivalents. On Listing Quality, IS24's 513,360 verified listings, Sprengnetter-integrated pricing accuracy, and AI image enrichment create a more complete and accurate inventory environment. immowelt's listing quality is supported by its CRM suite's structured data inputs but lacks equivalent public-facing quality signals. On Discoverability, IS24's 60% direct traffic share and 102.8M monthly sessions give it the strongest organic search and brand-navigation position in the German market; immowelt's multi-brand distribution partially compensates but the immonet consolidation creates short-term indexed-page risk. On Market Experience, IS24's end-to-end consumer journey — conversational AI search (HeyImmo), integrated mortgage (BauFi), valuation (Sprengnetter), and private subscription tiers — is the most documented and complete in the German market. immowelt's ancillary services (bauen.de, moving comparison) are useful adjacencies but do not constitute an equivalent integrated journey. On Product Innovation, IS24's documented AI stack, accelerating M&A programme (five acquisitions in 2023–2025), and international expansion via Fotocasa/Habitaclia Spain signal a company investing heavily in its future competitive position. immowelt's CRM suite and PE-backed operational investment are solid but less publicly documented and narrower in scope.

Frequently Asked Questions
- Is ImmobilienScout24 or immowelt larger in Germany?
- ImmobilienScout24 is significantly larger by all verified public metrics. Scout24 SE reports 102.8M monthly sessions (2024) and 19M monthly users (2025) for IS24, with 513,360 active listings and 26,000 professional customers. immowelt does not publicly disclose monthly visitor or active listing totals; third-party trackers indicate multi-million monthly scale but no audited figure is available for direct comparison. IS24's revenue (via Scout24 SE: €649.6M in 2025) and its MDAX listing further confirm its dominant market position.
- What is happening to immonet.de and how does it affect immowelt's competitive position?
- immonet.de is being consolidated into immowelt as part of AVIV Germany GmbH's brand simplification strategy. AVIV Group, the KKR/CPP-backed parent, concluded that operating two overlapping German portal brands was capital-inefficient. The sunset of immonet transfers its traffic and professional customer base to immowelt, which will concentrate AVIV Germany's portal audience under one brand. In the short term, this creates some indexed-page risk as immonet listings and URLs are migrated or retired. Once the consolidation is complete, immowelt's audience scale should improve, potentially narrowing — though not closing — the gap to IS24's session volume.
- How do ImmobilienScout24 and immowelt compare on agent pricing?
- ImmobilienScout24's verified professional ARPU stands at €1,095.98/month for the subscription component and €1,506.45/month in total billings (Scout24 reporting). This is the highest confirmed professional ARPU in the German portal market. immowelt's professional pricing is not publicly disclosed at the same level of granularity; directional estimates place professional packages at approximately €8,000/year (~€667/month). This makes immowelt approximately 44% less expensive per month on directional estimates, which is a meaningful factor for smaller agencies and high-volume rental operators managing cost per listing.
- Which portal has better AI and technology features for agents in Germany?
- ImmobilienScout24 has the most extensively documented AI and technology stack in the German portal market. Its deployed tools include HeyImmo (conversational AI assistant for property search), AI image search, TensorFlow-based listing ranking and buyer-seller matching, automated valuation integrated via Sprengnetter (acquired 75% stake in 2023), and the Realtor Lead Engine for agent lead qualification. On the CRM side, Propstack provides workflow tooling. immowelt's technology offer is anchored in the estateSmart/estateOffice/estatePro CRM suite and immosolve, which are solid professional tools, but no equivalent AI-layer product features have been publicly documented at the same level of specificity.
- Does using both ImmobilienScout24 and immowelt make sense for German property professionals?
- For most established German agencies and property managers, using both portals is the standard market practice and is likely to remain so even after the immonet consolidation into immowelt. IS24 is non-optional as the primary listing surface given its 102.8M monthly sessions and verified listing depth. immowelt adds incremental audience reach — particularly through its DACH network distribution and legacy immonet audience (during and after consolidation) — at a lower per-month cost. The combined estimated spend of approximately €2,173/month (IS24 ~€1,506 + immowelt ~€667) is a justifiable cost for portfolios where vacancy cost or transaction delay is expensive relative to portal fees. Smaller operators or those with very tight cost structures may opt for IS24 only, accepting the loss of immowelt's secondary audience.
