It's clear 2013 was a great year to be an investor. The market saw big gains across the board, with the Dow Jones hitting all time-highs throughout November, closing above 16,000 for the first time ever. Several stocks posted outstanding gains -- and Zillow (NASDAQ:ZG) was among them.

The home and real estate website operator saw its stock soar in 2013. Zillow posted impressive top-line revenue growth this year, as well as meaningful growth in both its audience and premier agent users. Motley Fool analyst Jason Moser believes the mortgage and rental sides of the business will be even more important for Zillow going forward.

Jason believes Zillow's future looks bright. The company is picking up market share from its competitors, and advertisers are increasingly drawn to it. Zillow stock looks like a solid long-term play.
