Places named when people ask
Each assistant was asked the way people ask, with web search on, for up to three places and a link to book or order with each one directly. The table shows how many of the places it named came with a link to the place's own site, to a marketplace or to a directory, or with no link at all.

| Claude | 78% | 5% | 2% | 15% | 59 |

Answers about the businesses
Each assistant was asked three questions about each of the top-ranked businesses in the index, with web search on: the website, where to book and where to order. The table splits its answers by where they pointed.
| Assistant | Own site or vendor | Marketplace | Directory | Nowhere | Answers |
|---|---|---|---|---|---|
| ChatGPT | 73% | 12% | 0% | 15% | 60 |
| Gemini | 82% | 12% | 3% | 3% | 60 |
Who gets named, and with which link
Asked on 2026-10-22. A place in this index links to its report. A place with its own site that isn't in the index yet links to a scan. "No link" means the assistant named the place but didn't link its site. Each question links to the full list of places named.
How this is counted
Everything here is counted in answers, using the latest answer from each assistant to each question, asked with web search on. Some questions are the ones people ask ("best pizza delivered right now", "book me a table for Saturday"). The others are three questions about each of the top-ranked businesses in the index: the official website, where to book and where to order. Every link in an answer is read. A destination counts once for each answer that links to it, whether as the place to book or as a source the assistant cited. So each share is the share of answers that link that destination, and the shares don't add up to 100%.
All the businesses' own sites share one row, whatever the business. A booking or ordering vendor on the business's own domain counts as direct. Marketplaces and directories are named. Listing, review and map sites (Tripadvisor, Google Maps, Yelp) count as directories, even where the scanner files them with the marketplaces. Newspapers, magazines, guides, forums and tourism sites share one row. Anything left is listed by its registered domain, and a model sorts each of those unknown hosts once into directory, press, marketplace, vendor, business or other, with the reason shown. Text that only looks like a host because a space is missing ("them.here") is dropped. Business names are matched against the index. A place that isn't in the index links to a scan of its site, if the assistant gave one.
