The deal, whose financial terms weren't disclosed, will bring Zillow's approximately 4 million property sales listings to Yahoo Real Estate later this year, but it will not affect the way Zillow's own Web site works, the companies said on Friday.
The deal will benefit real estate advertisers, such as brokers, home builders and homeowners, by streamlining the ad purchase process for the two sites and offering greater exposure, the companies said.
The agreement between Yahoo and Zillow doesn't include rental properties. The companies first partnered four years ago when Yahoo began displaying Zillow's property value estimates on Yahoo Real Estate.
In May, Zillow, with 7 million unique visitors, and Yahoo Real Estate, with 6.1 million, ranked second and third, respectively, in the U.S. real estate category, behind leader Move, which drew 12.4 million to its network of sites, which also includes Realtor.com and Moving.com, according to comScore.
Yahoo has struck similar partnerships in areas like personal ads through a deal with IAC's Match.com and job listings through its sale of Hotjobs to Monster.com, which in turn agreed to provide the content for Yahoo's career and job site. Yahoo is also implementing its search deal with Microsoft, in which Yahoo will rely on Microsoft for search crawling, indexing and ranking, as well as for pay-per-click ad sales.
