Bumper ads are very short ad videos that last for only 6 seconds. They are ideal for increasing brand awareness because they allow you to create brief yet compelling and memorable messages. Because they are so short viewers cannot skip them, but when they view these ads it will not increment the YouTube count of the video on the metrics. But they use target cost per thousand views bidding every time it is shown 1000 times. They work best when they run alongside Trueview ads and the short format makes them effective for running ads when people are on the go or watching content on their mobile devices.
