How this is read
Each assistant was asked each question once, with web search on, for up to three places and the link to each one's own website. Names are read from the answer and matched against the index. Any link between one name and the next belongs to that place. "With its own site" means the assistant linked the place's own website. "Through a marketplace" or "a directory" means it linked a listing instead, and "by name" means it gave no link. The direct links come from the Direct Index's own scan of the place's site. The assistant didn't supply them.
