Google Product Search now shows high quality YouTube video reviews on a number of product pages. Videos include reviews from USA Today, Wired, and Digital Trends, and they appear above the "Similar Items" section of the page. You can submitt your videos for review:

-Add the "youtube" attribute to your data feed. In this attribute include the YouTube video ID for each one of your products with a related YouTube video review. Video IDs are the values that follow the 'v=' in the YouTube URL of the video.
-Include UPC, ISBN, brand, and MPN information in the tag of your YouTube video review.
