How this is measured
Fourteen AI models from 12 labs are asked the same buying questions six ways, for three company sizes. Standings refresh every edition.
Gane sells AI visibility software. No company can pay to change a result.
Read the method →Sources returned with these answers
Fourteen of the fourteen models returned a source list in this edition: five return the pages they cited and nine the search results they consulted. These counts come from 26 of the 28 answers that named Signal and are not a share of its labels.
Domains cited
Forty-two of the forty-nine domain citations in answers naming Signal came from a third party's page. Seven were to the publisher's own pages (the Gane Index), which the models cite like any other source; they are not counted as a third party.

How it is countedHide how it is counted
Every page signal.org exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated.
