The real estate market needs a destination site on a domestic and possibly global basis, and that's what makes Zillow (NASDAQ:ZG) such an interesting investment prospect. The top online real estate marketplace could eventually rival the valuations of a LinkedIn or, which average more than $40 billion now.

The biggest issue in the real estate sector continues to be the lack of a comprehensive solution that incorporates all houses listed for sale. Several listing networks limit real estate listings to internal networks, hence the reason for the Trulia (NYSE:TRLA) purchase of Market Leader. The other threat has been Move, (NASDAQ:MOVE) which runs But both of those situations involve operating under the influence of Realtors instead of home buyers who want an independent website to view.

The recent announcement of Errol Samuelson joining Zillow as chief industry development officer ushers in an industry shift that Zillow has worked on for the last decade. Prior to this news, the shift was already manifesting in the monthly user numbers, but this move could help consolidate the industry. and Market Leader
Both, run by Move, and the Market Leader products purchased by Trulia focus on having home buyers view the individual websites of real estate agents. This traditional process of limiting exposure to the whole real estate market in order to focus sales on agent- and broker-related properties isn't going to work in the modern economy.

Back at the at the time of the merger with Market Leader, the platform offered Trulia access to 150,000 professional users, including the top brokerages of Keller Williams and Century 21. Also, the platform powers 120,000 agent websites, generating around 6 million monthly unique visitors. In total, Trulia saw only 35.3 million monthly unique visitors during the fourth quarter. Move, via, generated only 23.9 million monthly unique visitors.

The numbers just can't compare to the 54.4 million monthly unique visitors for Zillow during the fourth quarter, and the record 70 million reached during January.

Errol Samuelson
The most immediate implication of hiring Samuelson is the addition of a top executive in the real estate market and more importantly directly from competitor Move. Samuelson is the former president of and chief strategy officer at Move. His primary goal is to build and strengthen Zillow's relationship with brokerages, franchisors, MLSs, and trade associations. Also, he assumes executive oversight for the business-to-business products and tools, including Diverse Solutions and AgentFolio.

In essence, Samuelson's goal is to convince the industry to shift from building internal websites to listing homes for sale directly on His deep knowledge and connections in the industry from running could be instrumental in further turning Zillow into the dominant website in the industry.

Bottom line
Like all online markets, the real estate marketplace is quickly heading to one site that dominates the sector. The company will carve out a sizable valuation that could eventually match the riches of leading online travel site or the professional networking site LinkedIn. Zillow estimates that roughly $6 billion is spent annually on agent advertising, and that amount could skyrocket with a more efficient lead-generation platform. The recent hire by Zillow and market trends provide the company a giant leg up on being the dominant site for the online real estate market.
