Zillow (Nasdaq: Z) may be bringing up the rear in terms of alphabetical ticker symbols, but the recent IPO knows how to go to the head of the class by bringing home good grades.

The fast-growing real estate website delivered better-than-expected quarterly results last night, just as it did three months ago in its first financial report as a public company.

Zillow saw its third-quarter revenue soar 132% to $19.1 million. Adjusted earnings clocked in at $0.05 a share. Analysts were banking on a tweaked profit of just $0.03 a share on $17.1 million in revenue.

Zillow's success comes at a peculiar time. The residential real estate market is still feeling its way for a bottom. Realtor.com parent Move (Nasdaq: MOVE) doesn't report until after today's market close, but analysts see flat earnings growth on a 7% decline in revenue. Even if we head out to China where folks are still interested in real estate, China Real Estate Information (Nasdaq: CRIC) is growing its revenue at less than half of Zillow's pace.

So what's the secret to Zillow's success? A hook always helps. Just as priceline.com (Nasdaq: PCLN) was able to differentiate itself from the competition with its "name your own price" gimmick to nab travel portal traffic, Zillow's secret sauce may very well be its "Zestimates" -- rough yet sticky perpetually updated home appraisals and suggested rental rates on more than 100 million properties.

Easily accessible proprietary data is a potent hook, and Zillow attracted an average of 24.2 million unique monthly visitors to its website and mobile app, more than double the audience it was reach a year earlier.

If Zillow is where the homeowners, buyers, and sellers are hanging out that's where real estate agents will be, affording the dot-com darling the opportunity to milk juicy display advertising and marketplace revenue. Zillow has been able to take a page out of the Bankrate (Nasdaq: RATE) playbook by rolling out a mortgage marketplace, and on Monday announced a deal to extend that marketplace's reach through AOL's (NYSE: AOL) Real Estate and DailyFinance websites.

This has been a year of busted IPOs, but Zillow stands tall after back-to-back blowout quarters -- well above its $20 debutante price in July.

Zillow is the pretty house in an ugly neighborhood. Deal with it.
