Pinterest opens new ad buying tool to small advertisers

Pinterest now allows small and medium-sized brands in the US to buy ads on its platform using its new tool, and is increasing the number of interest-level targeting options from 30 to 420, making targeting more specific. However, as Pinterest expands its ad business the same tools are also expected to be made available to larger brands. 

Pinterest ads are getting more pointed. After 18 months of beta testing a self-serve platform that lets brands buy ads, the site is opening the tool to all small and midsize brands in the U.S. today.
