AI Search Visibility Audit of 100 Swiss SMBs (Ticino, 2026)

This dataset measures the technical readiness of 100 small and medium-sized businesses (SMBs) in the Ticino canton of Switzerland for AI-powered search engines such as ChatGPT, Claude, Perplexity, and Google AI Overviews. It replicates and adapts a methodology previously applied by Uberall to Italian restaurants. The 100 SMBs were sampled from OpenStreetMap (POIs with the website tag), primarily restaurants and hotels with a mix of pharmacies, dentists, and small retail. For each SMB, four binary technical signals were measured automatically: presence of schema.org markup (Organization/LocalBusiness or subclasses), presence of a valid /llms.txt file, robots.txt permissions for AI bots, and basic HTML structure (meta description + headings). Headline finding: 66% of SMBs are not optimized for AI search (score 0-1 out of 4). The dataset, methodology, and a Python script to fully regenerate it are released under CC-BY 4.0.
