A search engine ranks pages and sends you to one. An answer engine — ChatGPT search, Perplexity, Google's AI Overviews — does something different: it assembles an answer from sources it can parse and attribute, and most people never click through to any of them.
That difference is brutal for a business with no website. Under the old model you could still be found: your Google listing ranked, someone clicked it, they phoned you. Under the new one, you have no first-party source. An assistant asked "where should I eat in Skiathos Town tonight" can only describe you through third-party aggregates you do not control and cannot correct — or, far more often, skip you and name a place it can quote.
On this island that is not a hypothetical. 87 of 130 venues have no website of their own, and 34 score below 40 out of 100 on the citability measure below. Only 29 score 70 or above.
