These formats allow you to place video ads within video content being streamed online. Your ad can appear within popular content on YouTube – in full-length TV shows and movies and in front of clips from content partners – and on video sites on the Google Display Network, such as TMZ.com, About.com, and 5min.com (in the US).If you're focused on expanding your brand, in-stream video ads can help you make that happen. Nearly one third of time spent online is spent consuming video. With AdWords, you're able to target specific content without having to bundle your ads, and this also means detailed reporting so you'll know exactly where your ads appeared, and how customers interacted with them.How it worksThere are two templates for in-stream video ads within the Ad gallery:- In-Stream Video ad: Place a 15 or 30-second video ad within video publisher content.- Skippable In-Stream Video ad: Place an in-stream video ad that includes the option for customers to skip the ad within video publisher content. (This template has limited availability.)When an online video is served to a website in the Google Display Network, customers will see an in-stream video play automatically before, during, or after online video content depending on where the content publisher chooses to show ads within their video content. The video will cover the entire area of original content video space.The ad will play for a maximum duration of 60 seconds, although publishers can limit the ad content shown to 15 seconds or less. Web users won't be able to skip the in-stream video ad content.If the viewer clicks the ad while it plays, their browser will automatically launch the ad's Destination URL in a new browser window.
