Propelos publishes Marbella AI Visibility Index for real estate agencies

Propelos released a Marbella AI Visibility Index that measures which estate agencies ChatGPT, Google AI Mode, Gemini and Claude recommend to buyers in eight languages. The report ranks 62 agencies from 3,892 AI answers and shows how search visibility, language and cited sources shape which firms get named.

Why it matters: - Buyers are increasingly asking AI assistants which Marbella estate agent to call before they contact a human. - The index shows which agencies AI systems actually recommend, not just which agencies rank well in traditional search. - The findings suggest multilingual content, trusted sources and active business profiles can influence whether an agency gets named at all.

What happened: - Propelos published the Marbella AI Visibility Index, August 2026, on Sept. 8, 2026. - The report measures which estate agencies ChatGPT, Google AI Mode, Gemini and Claude recommend when buyers ask who to use in Marbella. - The index covers 62 agencies, 20 buyer questions and 3,892 AI answers across eight languages. - Propelos says every published name was verified by hand against a trading company. - The full report, data and method are free to use with attribution. More information

The details: - Local independents lead seven of the eight languages. - One Marbella independent leads five languages and holds 13% of position-weighted share of voice. - A second independent leads Swedish and Norwegian. - The market's global brand ranks second overall and leads only Spanish by three tenths of a point. - One answer in six names no agency at all. - In 16% of answers, the assistants recommend no agency. - Any two languages agree on average on 3.7 of the five names they recommend. - Four language pairs share only two names. - Swedish answers put two Swedish chains in the top five. - Dutch answers place a Dutch-language specialist fourth. - Norwegian answers name no Norwegian-run agency. - Of 2,400 searches captured from ChatGPT's and Claude's APIs before they answered, 23% of the most-run behind-the-scenes questions ask for reviews or ratings. - Those searches include operators such as site:trustpilot.com and Andalusia's official register of estate agents. - A small firm whose buyer guides the assistants cite ranks ninth of 62, ahead of several international brands. - idealista.com is the most-cited source, with 612 citations. - The Junta de Andalucía has 407 citations and is read more than every agency website but one.

Between the lines: - The data suggests AI visibility is shaped less by company size and more by whether assistants can read, trust and cross-check an agency across languages and sources. - The fact that one in six answers names nobody points to a meaningful gap for agencies that have not built content and citations AI systems can use. - The strong showing for local independents indicates localized authority can outrank larger brands in AI recommendations. - Propelos is measuring the same signals every week for agencies in its GEO program, turning the index into a benchmark and a sales tool.

What's next: - Propelos says its weekly program re-asks the same buyer questions across ChatGPT, Google AI Mode, Gemini and Claude and re-measures a week later. - The company offers a free AI visibility audit at propelos.com with 15 buyer questions and property searches per language, up to two of eight languages, a share-of-voice view, competitor comparisons and a readiness score out of 100. - The weekly service starts at €295 a month, with higher tiers at €1,200 and €2,400 a month, excluding VAT. - The report says the top 10 firms received the method and their own figures before publication. - The report, the eight language tables and CSV downloads are available online.

The bottom line: - In Marbella, AI assistants are already acting like the first filter for buyer attention, and the agencies that show up in those answers are gaining a new competitive edge.
