By brand: Fireflies vs Fathom

Two brands were used as samples in this study: Fathom and Fireflies. Here is how each landed, using only the searches where that brand was the subject (its "[brand] review" and head-to-head queries). You can reproduce any of this by filtering the dataset to that brand's queries.

Fathom's own pages were the 2nd most-cited domain; a competitor (tl;dv) was fourth.

What this shows

Across both brands the pattern held: YouTube was the single most-cited domain, each brand's own pages came next, and Reddit followed close behind. Competitor content (tl;dv, plus each brand's own "vs" page about the other) surfaced on the other's turf. A brand's own pages appear, but they are one layer among many, not the answer.
