Swiss Real Estate AI Visibility Index 2026

A prospect asks ChatGPT: "Which real estate agency do you recommend in Geneva?" The AI names three agencies. None of them is yours. This scenario is already happening thousands of times a day.

That is the question the Swiss AI Visibility Index answers, a series of studies measuring the visibility of Swiss companies in generative search engine responses. This edition analyzes 58 real estate agencies in Geneva and Zurich across 5 AI platforms. Rankings will be updated regularly to track changes over time.

Methodology

We queried 5 AI platforms with 12 real estate prompts (6 in French for Geneva, 6 in German for Zurich) across 7 measurement sessions in March 2026.

The prompts cover 6 verticals: rental, buying, selling, investment, valuation and general comparison. These are the real use cases of a prospect.

The 5 platforms tested:

• ChatGPT (OpenAI)
• Gemini (Google)
• Claude (Anthropic)
• Google AI Mode (Google Search generative results)
• Perplexity (AI search engine)

For each response, we extracted the named agencies and measured their frequency of appearance, position in the response and associated sentiment.

The Overall Ranking

Here are the 20 most visible agencies in AI responses, across all platforms and languages. The visibility rate represents the percentage of responses in which the agency is named.

Neho leads with 43%. It is the only agency that ranks first in both French (44%) and German (41%). Its fixed-fee model and digital-first approach seem particularly well captured by AI systems.

Who Leads by Vertical?

Not all agencies are recommended for the same needs. Here are the leaders by use case, the most actionable data in this study.

Rental

The most contested vertical. Real estate portals dominate because AI systems often redirect to listing platforms.

Buying

For purchase queries, traditional and international players regain the advantage over portals.

Selling

The question "how to sell quickly?" generates responses more focused on advice than agency recommendations. Portals are still cited as distribution channels.

Investment

The vertical where specialized players stand out. AI systems recommend agencies with yield and wealth management expertise.

Valuation

The "free valuation" vertical is dominated by players offering online tools. Traditional agencies are virtually absent.

Geneva vs Zurich

The two markets show very different dynamics.

Geneva: traditional agencies dominate

The average visibility of the Geneva top 5 is 36%. The market is fragmented between established agencies and international luxury players.

Comptoir Immobilier and Naef Immobilier, two established Geneva agencies, hold podium positions on the French-speaking side. But neither appears in German (0%).

Zurich: Engel & Völkers dominates the market

The average visibility of the Zurich top 5 is 38%, driven by Engel & Völkers at 71%.

The Bilingual Gap

Out of 58 agencies detected in AI responses, only 5 are visible in both languages (>10% in FR and DE). This is the most striking finding of this study.

Neho and RealAdvisor are the only ones with true bilingual balance (gap < 5 points). The others have a dominant language.

Platform Differences

Not all AI systems recommend the same agencies. Here is how Neho, the leader, is perceived by each platform:

Claude is the most conservative: it favors generic recommendations over specific agency names. Perplexity is the most generous with mentions.

Sources That Influence AI Systems

Beyond agency websites themselves, which third-party editorial sources do AI systems cite most in their real estate responses? This ranking reveals the sites that "carry weight" in AI recommendation algorithms.

Most Cited Agency Websites

Agency websites are directly cited as sources by AI systems. The citation ranking closely mirrors the visibility ranking, but not exactly.

Editorial Sources and Press

Beyond portals and agency websites, AI systems rely on editorial content to build their recommendations. Blogs, press, independent comparison sites: these third-party sources act as "endorsements" and directly influence which agencies are cited.

Three Levers to Improve Your AI Visibility

The data from this study suggests three courses of action for agencies that want to be recommended by AI systems.

1. Structure your content for machines. AI systems extract information more effectively from pages with clear factual data: areas covered, commission model, client reviews, listed services. Neho and Properti excel here thanks to their conversion-oriented websites.

2. Get cited by trusted sources. Being present on Homegate, ImmoScout24 and Comparis is not just important for SEO. It also builds credibility with AI systems. Portals act as "endorsements" in generative responses.

3. Invest in both languages. The vast majority of agencies are visible in only one language. This is the most underexploited lever in the Swiss market.

Conclusion

Neho leads the ranking with 43% visibility and a unique bilingual advantage. Traditional agencies remain strong locally but become invisible as soon as the language changes. GEO is a new playing field: those who act now will gain a lasting advantage.

Upcoming editions of the Swiss AI Visibility Index will cover:

• Law firms (Geneva vs Zurich)
• Accounting and fiduciary firms
• Clinics and medical practices
• Hotels and tourism
• Insurance (2026 update)

Does your agency appear in AI responses?

This ranking shows the most visible agencies. But where does yours stand? When a prospect asks ChatGPT or Perplexity for a recommendation in your area, does your name come up?

The agencies in this ranking didn't necessarily "optimize for AI." They benefit from structured content, presence on the right portals, and mentions in third-party sources. These are levers accessible to any agency, regardless of size.
