Over the last decade, a group of growing and mostly profitable websites such as Redfin, Zillow, Trulia, and Realtor.com have sprung up to provide easy-access information to consumers through what in many cases will be the largest and most nerve-wracking transaction of their lives. What percentage of consumers start their real estate journeys on one of these sites?

Studies show 92% of consumers now start their real estate journeys on the Web -- frequently via one of these sites. However, 90% of buyers still use a real estate agent to manage their home purchase, according to the National Association of Realtors.
