An interesting article from Inman the other day where the top 3 real estate portals are really dominating the search results. Zillow was at the top with 16.53 percent of real estate traffic. Then came Trulia with 8.66%. Rounding out the top 3 was Realtor.com (which used to be #1) with 7.26%. But what these numbers do not show is Zillow also powers several other websites, including Yahoo Homes, which is #4. So you have Zillow with over 64 million monthly visitors to their site and listings. Realtor.com does power MSN Real Estate, so together, they represent about 26 million monthly visits.
