Racked reports that Pinterest is finally rolling out ads, aka "Promoted Pins," on its platform. The first phase of the program is being tested right now in the US. The list of brands selected for the test phase includes Target, Lululemon, and the entire Gap family (Gap, Old Navy, Banana Republic). "These brands will help us test Promoted Pins to make sure they're tasteful, transparent, relevant and improved based on Pinner feedback— so that Pinterest continues to be a great experience for everyone," writes Joanne Bradford, Pinterest's new head of partnerships. Shown here is a prototype "Promoted Pin" for Old Navy.
