There are several different types of video ads, including: 1. Pre-roll ads: Pre-roll ads are video ads that are played before the main video content. These types of ads are often used to capture the viewer's attention at the beginning of the video and to set the context for the content that follows. 2. Mid-roll ads: Mid-roll ads are video ads that are played during the main video content, typically at a natural break point in the video. These types of ads can be used to keep the viewer engaged and to provide a break in the content. 3. Post-roll ads: Post-roll ads are video ads that are played after the main video content. These types of ads are often used to leave a lasting impression on the viewer or to encourage them to take a specific action. 4. In-banner video ads: In-banner video ads are video ads that are displayed within a banner or banner-like ad unit on a website or platform. These types of ads are often set to autoplay when the webpage is loaded and can be a good option for advertisers who want to reach a wide audience. 5. In-article video ads: In-article video ads are video ads that are placed within the body of an article or blog post. These types of ads are often integrated seamlessly into the content and can be a more subtle way to reach viewers. 6. In-feed video ads: In-feed video ads are video ads that are displayed within a feed or stream of content, such as a social media feed or a news feed on a website. These types of ads are often blended in with the surrounding content and are designed to be relevant and engaging to the viewer.
