TrueView in-stream ads
How TrueView in-stream ads work
TrueView in-stream ads run on videos served on YouTube or on a collection of sites and apps in the Google Display Network (GDN). These ads may also run on YouTube videos that are embedded on other sites or apps. They can also appear on Android and iOS YouTube apps, m.youtube.com (on iPad and Android), and on connected TVs.
Viewers can choose to skip the video ad after 5 seconds. If they choose not to skip the video ad, the YouTube video view count will be incremented when the viewer watches 30 seconds of the video ad (or the duration if it's shorter than 30 seconds) or engages with your video, whichever comes first. Video interactions include clicks to visit your website, call-to-action overlays (CTAs), cards, and companion banners. If view counts on YouTube are a concern, it's a good idea to make videos at least 12 seconds long. YouTube analytics doesn’t track views less than 10 seconds.
TrueView in-stream ads can be created using AdWords.
VPAID is not allowed on YouTube.

Reporting metrics and third-party tracking
Tracking within YouTube video content
Including third-party tracking pixels is optional. However, if you include them, they must meet requirements for third-party ad serving. They must also follow these requirements:
- Impressions: 1x1 tracking pixel accepted
- All tracking pixels and any fourth-party calls made within the pixels from daisy-chaining must be SSL-compliant.
- 1x1 image pixels are allowed on the impression, view, and skip events, but not midpoint and complete events.
Companion banner ads (optional)
If a companion ad isn't provided, no other advertiser's ad will appear next to your pre-roll. When comparing video impressions with companion impressions remember that companion banner ads are not served on all YouTube pages where in-stream ads are served
Companion banners won't show for in-stream ads shown to users watching videos on YouTube Leanback, whether on GoogleTV or in their browser.
- Image: Ads must meet our image ads requirements.
Call-to-action (CTA) overlays
CTA overlays are provided for TrueView in-stream ads and in-stream ads bought on reserve in Google AdWords.
- Headline text: 1 line of 25 characters maximum (any more than 25 will be truncated on some devices)
- Display URL: The URL displayed to the users on the overlay
- Destination URL: The URL to which the overlay links. Can be a redirect and/or link to an external site.
- Thumbnails must be hosted on YouTube.
- JPG or GIF only
- 74x74 pixels
How CTA overlays work
The CTA overlay appears as soon as the video starts playing, and then collapses to show just the thumbnail image after 15 seconds. On desktop browsers, viewers can hover to expand the CTA. On mobile browsers, viewers can click the thumbnail image or arrow to expand it.
