Shares of Zillow (NASDAQ:ZG) are down a bit before the company's earnings announcement later today. Motley Fool One analyst Jason Moser is keeping a close eye on the company's top-line growth, something that's important for small-growth companies like Zillow. Jason will also be looking at traffic, which increased by 14 million unique visitors last quarter.

In fact, Jason was skeptical about Zillow at first, and was unsure how real estate over the Internet would be received. He's changed his tune, though, and has been impressed by the amount of data Zillow produces, the company's business plan, and its first-mover status in an increasingly mobile market.
