For those who have recently checked out Zillow and did any type of search, you probably noticed a few of the changes we’ve made.  This is a result of the official launch of Zillow® Smart Search, the dynamic new version of our search technology that helps you search and navigate all of the real estate information you can find on Zillow.  We’ve been enhancing our Web site since Zillow debuted almost two years ago and what we released today includes significantly more capabilities.

One of the biggest challenges we face here at Zillow is also one of our greatest attributes—we have so much data and informationon homes!  At times, this can be overwhelming but our jobs are to continue making your experience on Zillow easier and more meaningful.  If you haven’t yet seen it, enter an individual address, try searching for neighborhoods or cities and zoom in and out on the map to see what we have pulled together. I think you’ll agree, Smart Search is pretty different from what’s out there today.

In fact, we think it’s so different that we have patents pending on the technology and infrastructure behind how this all works.  The Smart Search system has been built to handle simultaneous and complicated queries fast enough to update search results in real-time and intelligently choose whether to show individual properties or group search results by neighborhood, ZIP code, city, county, or state. Our smart filters guide you through the information and let you slice the results and hone in on the properties that most interest you.


It’s pretty exciting for me and the product and tech teams who have made this a reality and I want to thank everyone for their long hours and dedication. So how hard was it?   Well, I did a few calculations and have determined that we likely spent about 25,000 man hours developing what you see today, from design, writing code, testing, usability studies and more. And while nothing gets built at Zillow without a big dose of team work, I have to acknowledge Randy Puttick, who is the real architect behind Smart Search.

And if that wasn’t enough, I also want to point out our revamped neighborhood pages that were also introduced today.  The changes we made were in part a result of some very helpful feedback from our visitors. You’ll now find demographic information about the people who live in each ‘hood – age, income levels, education, homeowners vs. renters, etc— as well as some data unique to Zillow such as the Zindex across markets, the number of homes that have been flipped (bought and resold within a year) and the Zestimate distribution, which shows you home value trends across an area.

Keep your eye on our blog for some more detailed posts on these new features from some key product team members.  Happy searching!

UPDATE: As with many new releases, we have seen a few bugs pop up here and there that could affect your initial experience using our Smart Search technology. These primarily affect those using a Mac with a Firefox browser and may also intermittently affect Zindexes from popping up within our new boundaries. If you’re on a MAC, try to using the new version of Safari. We’re working diligently to get these fixed, but if you noticed anything that doesn’t seem quite right, please do leave a comment and let us know. We appreciate your patience and hope you’ll check back soon.

    I like the ease of Zillow. I use it to take a look at a property before I get order an appraisal. Also, as a realtor I like to see how it compares to doing a CMA on my local MLS. I find that in my area the houses are in a decline in value but Zillow still shows a high value. It is a nice tool but not sure the how valid it is when houses are showing up with 2005 price structures and my appraisers are showing the real 2007 value. Overall, I like to use it and think with a little tweeking it will be a future tool many will access.

    I don’t like the new changes! It was easier to search for either “For Sale” or “Make Me Move” properties yesterday. Can you fix the site so that we can search for both types of properties simultaneously? Thanks, Jon

    I’m using Firefox with a G4, OS X.3.9. Apple no longer supports safari on this OS but Firefox continues to update the browser. I’m experiencing problems too numerous to list with searching. I suspect you are aware of them, or, if not, please access your site with Firefox to see for yourself the mess users like me now have. If you want me to list all of the problems I have found, let me know. Also, if I had some way to send graphics, ie if we could communicate via e-mail, I could send pictures that would be much clearer than an attempt at a text description of the problem. Thanks

    The new search is great. I especially like the fact that you can see the result size on the options. Clicking on the listing details should open on a new page though, so that the map is not lost.

  • Minnesota & Wisconsin Lake Property

  • Asia Luxury Property

    Great work on this website! Look forward to seeing more property news here!

    I have the same problem Jeanette was having on Aug 10th, 08 except I downloaded and installed the latest flashplayer and STILL have the problem. Prior to that when I could search I could not figure out how to get to the last sale and property tax data like I used to. Please fix – I’ve told 100s of person’s about this great site & it’s tools. TIA, Cece
