The top 10 splits cleanly into two neighborhoods: a tight real estate and housing cluster at the top, and a second pull toward finance brands — a bridge that defines Zillow's two-peak shape.

Inman News (0.98) is the strongest signal, a News Publisher whose audience composition nearly mirrors Zillow's own. Right behind it, Trulia (0.97) is the one other Technology brand in the top 10, and National Association of Realtors (0.96), REALTOR Magazine (0.96), and HousingWire (0.96) round out a dense cluster of real estate trade media and professional organizations. Three Real Estate brands — CENTURY 21 (0.95), Coldwell Banker (0.95), and Keller Williams (0.89) — sit alongside Realtor.com (0.94), a Websites entry. That first neighborhood is almost entirely real estate industry infrastructure: trade publishers, brokerages, and professional groups.

The second peak arrives with Freddie Mac (0.93), a Finance brand whose audience shape pulls noticeably away from the brokerage cluster. WSJ Mansion (0.89), a News Publisher with a finance-adjacent readership, sits at the seam between the two neighborhoods. Together, the top 10 shows an audience that spans working real estate professionals and housing-finance observers — two distinct but overlapping communities sharing the same attention profile.

The two-peak structure suggests Zillow's audience is not monolithic: it bridges the practitioner world of agents and trade media with the institutional finance world of mortgage-market watchers.
