The top 10 neighbors for HHS.gov form a tightly compressed band — similarity scores run from 0.93 down to 0.90, a span of less than four points — with no single dominant neighbor pulling away from the rest.

The shape is flat, and the composition tells the story. Tallying subcategories across the top 10: four neighbors are Government entities (CDC eHealth at 0.93, U.S. Surgeon General at 0.92, Centers for Disease Control and Prevention at 0.91, and U.S. FDA Recalls at 0.87), three are News Publishers (The Washington Post at 0.92, BBC Health News at 0.92, and CNN Breaking News at 0.92), two are Non-Profits (American Medical Association at 0.92 and World Health Organization (WHO) at 0.92), and one is a TV Show (60 Minutes at 0.90). The mix is government agencies, health-adjacent non-profits, and general-interest news — a cluster that reflects an audience tracking public health and policy information across institutional and journalistic sources simultaneously. The lone outlier in kind is Beth Doane, an Author at 0.91, whose presence alongside federal agencies and major news outlets is the one cross-kind signal in an otherwise institutional set.

The flat, compressed shape indicates an audience with broad overlap across public-sector health, non-profit health advocacy, and mainstream news — no single neighbor defines it, and no single category dominates it cleanly.
