Pinterest has launched Promote a Pin, a feature that lets users boost their content's reach without designing complex ad campaigns.

The social media platform is rolling out the feature to USA users in the coming weeks, with global expansion planned.

Pinterest said its 619 million active users drive more than 80 billion searches monthly, with over half commercial in nature. The feature uses Pinterest's Taste Graph system, trained on billions of images, to target users likely to convert.

Users can set parameters including daily budget, campaign length and target audience. The platform shows estimated results based on these settings.
