How this is measured
Names are matched case-sensitively from each brand's own homepage title, in answers stored by the Machine Relations Index. Only derived counts are published here; no answer text is.
A brand appears only once it has been named in at least 10 answers on 7 separate days.
A name match counts a mention. It does not count a recommendation, and it does not measure sentiment.
Categories are the Index's buyer-question categories.
