I'm pleased to post our June traffic stats. As readers of this blog already know, I do this every month (or at least every month that I find time to do it).

First, a note about the data: at Zillow, we strongly believe that the only reliable way to measure traffic is with your own internal traffic logs. Publicly available sources like Comscore, Nielsen, Hitwise, Alexa and Quantcast all take small panels of Internet users and extrapolate to guess at your overall traffic. While we're very pleased that Hitwise and Nielsen consistently report that Zillow is now the 2nd largest real estate site on the Web, we still believe that internal measurement is more reliable. So the data below comes from Omniture, which is a public company to whom we pay a small fortune for their site analytics package. Again: because this is plugged into our actual website, it's much more reliable than Comscore or any other public reporting.

Without further ado, the highlights:

• In June 2009, Zillow had 8.5M unique visitors, up 67% year-over-year.
  
• In June 2009, Zillow had 14.1M total visitors, up 60% year-over-year.

• Our largest city is Los Angeles where we had 1.5M total visitors, up 38% yoy. New York was #2 with 1.1M visitors (up 79% yoy), and San Francisco was #3 with 1M visitors
• Our traffic in Washington DC grew the most of any large city, almost doubling yoy (up 91%) to 572K visitors

• The penetration stats are pretty amazing also. Nationwide, about 5% of all US residents visited Zillow in June. In San Francisco, 16% of all residents visited in June; in Seattle, 11.3% of all residents visited in June.
  • While we don't know what % of homebuyers in a given city visited, it's safe to assume that with these types of penetration stats for ALL residents, we must also have very high penetration stats among buyers.
  • Also, the California of Association of Realtors just released a study showing that 55% of all Internet buyers (which is pretty much everyone) use Zillow -- more than Yahoo Real Estate or Craigslist. (Trulia didn't register enough buyers to be on CAR's list.)
    
  • Our own research shows that about 2/3 of our visitors are in the market to buy or sell a home, so Zillow definitely isn't just for voyeurs.
