The top 10 neighbors for SmartBrief span B2B research firms, professional websites, business authors, and a tech personality — with no single neighbor pulling far ahead of the rest. Similarity scores run from Gartner at 0.94 down to Guy Kawasaki at 0.91, a range of just 0.03 across ten positions. That compressed band is the defining structural feature here.

Tallying the top 10 by subcategory: four are B2B brands — Gartner (0.94), Forrester (0.93), Marketo (0.93), and IDC (0.92) — forming the densest cluster. Three are Websites sharing SmartBrief's own subcategory: CIO.com (0.93), InformationWeek (0.92), and Marketing Land (0.91). One Technology brand, Salesforce, sits at 0.92. The remaining two are Celebrities and Influencers: Guy Kawasaki as a Tech Personality (0.91) and Seth Godin as an Author (0.91). No fitness brands, hotels, or political figures appear in the top 10, though they surface further out in the broader graph.

The overall picture is a tightly professional, B2B-and-tech-media audience — one that follows analyst firms and enterprise software brands with the same attention it gives to practitioner-facing publications and thought-leader voices.
