Sample EZ Ad

Real estate site Zillow.com this week launched "EZ Ads," a do-it-yourself system that allows users to create an ad and purchase space locally, by geography or ZIP code, reports MediaPost.

Another new addition is a question-and-answer function similar to Yahoo Answers, along with a digg-like feature allowing visitors to rate answers as "helpful" or "not helpful."

What has made the site attractive to advertisers such as Lendingtree, Washington Mutual, Bank of America and dozens of others is the quality of its visitors: 84 percent own a home, most are affluent, and they're concentrated on the East and West Coasts.

Last month, Zillow ranked No. 7 in site visits in the real estate category, according to Hitwise. Lanched in the first quarter of 2006, the site has surpassed expectations. Its founders had projected 1 million unique visitors by August 2006; instead, Zillow attracted 5 million unique visitors in just three weeks.
