In recent years, the real estate website Zillow.com has seen increasing traffic. According to the traffic reporting site Alexa.com, Zillow's traffic is close to reaching, at long last, the venerable and dominant Realtor.com, which in years past we have favored over all other sites, mostly because of its excellent and fair search results (giving users what they need, not what advertisers want), and because of its towering dominance in national listings websites.
