Shares of Zillow have been gaining steam in recent days, once again topping $30 per share and giving the Seattle online real estate company a market value of more than $1 billion. And now here’s another shot of good news for Zillow, which is announcing today that it has renewed a deal with real estate giant Century 21.

As part of the deal, Century 21 said it plans to continue to distribute listings through Zillow, a shot in the arm for the company which has seen some defections by smaller brokers who don’t like playing ball with the fast-growing media company.

Century 21 has a long history with Zillow, becoming the first national real estate company to participate in Zillow’s advertising platform. Century 21 agents will continue to get preferred marketing as part of the agreement.

“We are very proud of our strong relationship with the Century 21 System, and I’m extremely pleased to extend our marketing partnership,” said Greg Schwartz, chief revenue officer at Zillow. “This partnership affords Century 21 agents and their customers extremely efficient online marketing tools with automated listing syndication on the largest real estate network. This is a significant advantage for sellers to reach active and highly-qualified home shoppers who want free and easy access to all the listings in their area.”

Zillow as well as its longtime rival Trulia have received criticism in the past for not having comprehensive for-sale listing information from agents, the subject of a Redfin-sponsored study earlier this year.
