What do you use YouTube for? Do you upload your own content? Watch videos? Stream playlists? Subscribe to certain channels? Is there an age gap in the way groups interact with the site? When it comes to the different types of available ads, what are the pros and cons of each? Display ads: Traditional web units that usually appear to the right of the video. Overlay ads: Semi-transparent ads that appear on the lower 20% portion of a video. 0 Skippable video ads: Video units that allow viewers to skip ads after 5 seconds. Non-skippable video ads: Video units that must be watched before the main content. Bumper ads: Non-skippable video ads of up to 6 seconds that must be watched. Sponsored cards: Text/display units that display alongside the main video.
