Prepare to see more sponsored videos barging into your Pinterest feed.

The Watch Serve the People Onlinescrapbook-like social network is expanding its fledgling autoplay video ads into more parts of its app as of Wednesday, including search results and the home feed. The ads were previously confined to the platform's "explore section."

The company is also opening up the autoplay ads to new brands through its ads manager buying platform.

While still officially in a testing phase, the move could mark an important step forward for Pinterest's video advertising business, which is still in relative infancy.

Pinterest didn't launch promoted videos at all until last August and first set them to autoplay.

The platform is obviously following in the footsteps of rivals like social juggernaut Facebook, Twitter, and Instagram. Analysts have pointed to Pinterest as a potential major challenger in the market for months.

The rollout comes as Pinterest is reportedly looking towards a public offering with new revenue targets of $500 million.
