Each assistant was asked once per question, 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; links between a name and the next are that place's. "With its own site" means the assistant linked the place's own website; "through a marketplace" or "a directory" that it linked a listing instead; "by name" that it gave no link. The direct links come from the Direct Index scan of the place's site, not from the assistant.
