Zillow

Zillow.com is one of the most prominent online real estate platforms in the United States, serving millions of monthly users with tools and data for residential and commercial real estate transactions. Launched after its domain registration in 2004, the platform revolutionized public access to property data, giving everyday consumers the ability to look up home values, view property listings, and research neighborhoods without needing to contact a real estate agent first. Core offerings on the site include its signature Zestimate home valuation tool, which uses public and user-submitted data to generate estimated market values for millions of homes across the country. The platform connects buyers, sellers, renters, and real estate professionals, streamlining the process of listing properties, scheduling tours, and completing transactions. Zillow also offers additional services including mortgage financing, tenant screening, and moving coordination, expanding beyond its original listing-focused model to become an end-to-end real estate service provider. As of 2025, Zillow ranks among the top 1000 most visited websites globally, a testament to its widespread adoption and ongoing relevance in the fast-growing digital real estate industry. The platform has transformed how people approach real estate transactions, democratizing access to market data that was previously only available to industry insiders, and creating a more transparent experience for all participants in the housing market. It continues to innovate with new features, including AI-powered home search and improved valuation accuracy, to maintain its leading position in the competitive online real estate space.
