Google's TrueView is built on the promise that you'll only pay when someone chooses to watch your video ad.
How it works
Why bombard users with ads they don't want to see? With TrueView, you give them a choice, and it's a win-win: Viewers see videos they're curious about, and you get more views from an audience you know is interested. And since you choose what you want to pay for a view, you get the right audience at the right price.
TrueView ads are opt-in, so you aren't restricted by time limits. This means you have the freedom to experiment with creative formats–try a longer product demo, testimonial or how-to video demonstrating your product in action. With TrueView you can take the time to tell your story.
2 Types of TrueView
In-stream ads play before or during another video from a YouTube partner. Viewers see five seconds of your video and then have the choice to keep watching or skip it.
You pay when a viewer watches for at least 30 seconds or to the end of the video (whichever is shorter) or clicks on a card or other elements of your in-stream creative.
TrueView video discovery
Video discovery ads appear alongside other YouTube videos, in YouTube search pages, or on websites on the Google Display Network that match your target audience.
You pay only when a viewer chooses to watch your video by clicking on the ad.
