Pinterest has hired Joanne Bradford as its first head of partnerships. The social network says that Bradford will develop advertising and media partnerships across the globe, as well as craft new ad formats.

In doing so, she’ll continue Pinterest’s efforts to figure out ways to earn revenue from its large, engaged user base. The social network is the 13^th most-visited site in the United States, according to Alexa Internet Inc., a subsidiary of Amazon.com Inc., and its average visitor spends more than 7 minutes and 38 seconds on the site per visit.

Pinterest last month debuted its first ads, which the social network calls “promoted pins.” The ads appear in search results and category feeds for both desktop and mobile users. For example, a costume shop might promote a pin for a Santa Claus costume when a user searches for “Christmas.”

Bradford has worked at various advertising and digital media companies throughout her career, including roles such as chief media officer at Microsoft Corp. (from 2006 to 2008), senior vice president revenue and market development at Yahoo Inc. (from 2008 to 2010), and chief revenue and marketing officer at Demand Media Inc. (from 2010 to 2013), according to her LinkedIn profile. Most recently she was president of the San Francisco Chronicle newspaper.
