The top 10 neighbors split into two distinct neighborhoods: a tight real-estate-industry cluster at the high end, and a second grouping of finance and news publishing entities that pulls the shape toward a broader professional audience.
Similarity here measures how closely two entities' audiences resemble each other in composition. The dominant cluster is unmistakable. National Association of Realtors (0.99) and Realtor.com (0.98) sit at the top, followed immediately by Inman News (0.97) — a real estate news publisher — and the property-search platforms Zillow (0.96) and Trulia (0.96). Three real estate brokerages round out the upper band: Coldwell Banker (0.96), CENTURY 21 (0.95), and Keller Williams (0.93). The subcategory tally for these eight neighbors spans Professional Groups, Websites, News Publishers, Technology, and Real Estate — all orbiting the same industry.
The second peak arrives at positions nine and ten, where HousingWire (0.93, News Publishers) and RE/MAX (0.92, Real Estate) hold. Just outside the top 10, Freddie Mac (Finance) at 0.91 signals that the second cluster tilts toward mortgage and finance infrastructure rather than brokerage. No other magazine appears in the top 10; REALTOR Magazine's nearest neighbors are entirely drawn from the industry it covers, not from the publishing category it belongs to.
The two-peak shape reflects an audience that is simultaneously a professional trade readership and a real-estate-transaction ecosystem — practitioners and the platforms they use, not general consumers.
