We put a category's real questions to the major assistants and write down every brand that comes back. Each table is published with the questions that produced it, the number of answers collected, and the day they were collected.
No share here is ever printed without what it is a share of. You will not read “23% of the market” on this page — you will read “named in 23 of the 100 answers we collected”, because that is the only one of the two we can show you the working for.
No edition is published yet.
The first one goes up when a category has been measured properly — at least 20 questions across 2 assistants — and a person has read it. Three plausible-looking tables would be faster and would make this section worth nothing.
In the meantime the same check runs on your own site, with your questions and your name in the table.
