More than 30% ads with a sticky video

This is a combination of two things on the same desktop page. The first is ad density above 30%: the ads take up more than 30% of the height of the main content. The second is a sticky video ad, one that stays stuck on the screen and follows the scroll. When both appear together, the page falls below the standard. For comparison: without the sticky video, the desktop density rule only covers pages above 50%.

The Coalition for Better Ads makes it clear that the sticky video counts with or without a close button: both the sticky video that can be closed and the one that cannot are included. Having an "X" on the video therefore does not take the page out of this rule.

Density is measured the same way as in the other rule. Add up the height of all the ads inside the main content and divide by the total height of that content. The measurement is made on the main content, not just on what appears on screen. The site's header, footer and navigation, including related articles, are outside the main content. Ads below the main content are not counted. Ads on the sides of the content are counted. All formats count, sticky and in-text, and each sticky ad counts only once. Pre-roll and mid-roll of a video related to the page topic are not part of the measurement. In practice, it is a choice: either the sticky video with density of 30% or less, or density above 30% (up to 50%) without a sticky video.
