Treehugger's top 10 neighbors span journalists, authors, environmental organizations, activists, and NPR properties — with no single entity pulling far ahead of the rest. Similarity scores run from 0.96 down to 0.93, a narrow band that signals a flat audience shape: the audience overlaps broadly across a recognizable cluster rather than concentrating around any one neighbor.
grist (0.96) sits at the top, the only other website in the top 10 that shares Treehugger's own subcategory. From there, the neighbors are almost entirely cross-kind: Bill McKibben (0.95) and Guardian Environment (0.95) represent journalists and news publishers; Robert Reich (0.94) is a politician; Margaret Atwood (0.94) and Michael Pollan (0.94) are authors; The Nature Conservancy (0.94) is an environmental organization; The On Being Project (0.93) and Fresh Air (0.93) are podcasts and radio; and Indivisible Guide (0.93) is an activism organization. The dominant subcategories across the ten are journalists, authors, and environmental/activism organizations — a mix that skews heavily toward civic and literary voices rather than other sustainability-focused websites.
The flat shape here reflects an audience whose composition is defined less by a single adjacent entity and more by a consistent orientation across progressive media, environmental advocacy, and public-interest journalism.
