Methodology

Each market is probed with 15 hand-curated holiday-search queries against four AI engines (ChatGPT via OpenRouter, Claude via OpenRouter, Perplexity sonar-pro, Gemini via OpenRouter). Engine coverage = % of queries where the engine returned at least one specific business name (not a refusal or generic OTA link). Rank movement compares the earliest and latest snapshot inside the4-week trailing window. Data frozen at 2026-W27 window end — this URL will never be edited.
