There are three key types of video ads in which you can invest in YouTube: TrueView, Preroll, and Bumpers.
1. TrueView Ads
TrueView ads are the standard video Ad type on YouTube. Advertisers only pay for TrueView ads when viewers watch or interact with their ad (for example, by clicking on a call-to-action), and videos can be easily customized to share a variety of content.
Advertisers only pay when a user watches the ad for at least 30 seconds or until the end of the video or if the viewer takes an action, such as clicking on a call-to-action. YouTube requires that skippable TrueView ads be between 12 seconds and 6 minutes in length and that non-skippable TrueView ads be 15-20 seconds in length.
TrueView in-stream ads play before someone watches the video they’ve selected on YouTube. Viewers sometimes have the option to skip the ad after watching it for five seconds. You can also make them play anywhere in the Google Display Network (GDN) — or sites that purchased Google video ad space.
In-stream ads let marketers customize video ads with different CTAs and overlay text.
2. Preroll Ads
Some in-stream ads are non-skippable and can play before, mid-roll, or after the main video. These are called Preroll ads, and they can be 15 to 20 seconds in duration.
Bumpers are the third and shortest type of YouTube video ad available to you. At just six seconds per bumper, these ad spots play before a viewer’s chosen video.
Bumper video ads obviously can’t tell a good-enough story in just six seconds, but they make terrific complements to larger video campaigns on a new product launch or event. Just be sure to use this six seconds wisely, and include only the components of your brand you want your audience to remember.
