Over the past eight years, Leaf Group (formerly known as Demand Media until 2016) has transformed itself from a SEO-focused content farm to a commerce-driven media company that sold for $323 million to Graham Holdings last June.

Much of that transition was done at the hands of CEO Sean Moriarty, who wanted to build a portfolio of expert-led content that readers turn to when making purchases. And now the media side of the business earns about two-thirds of its revenue from its commerce business, Moriarty said on the latest episode of the Digiday Podcast.

Moriarty joined Leaf Group after the media company acquired online art marketplace Saatchi Art in August 2014, where he had served as CEO for a year.

The addition of the artwork marketplace (and Society6, another marketplace Leaf Group acquired in 2013 that turns its network of artists’ designs into buyable HomeGoods) has taught the media properties in the portfolio a lot about e-commerce, he said.
