As part of our Google Images redesign this July, we introduced Image Search Ads, which include a thumbnail alongside your ad text. We learned that on Google Images, image-based ads provided great results for our advertisers. They are also a highly useful format for users because they show commercial content directly related to the user's query.Today we're expanding the image ad formats available on Google Images by testing rich media leaderboard units that appear above Google Images search results and invite you to try new products and services. With the introduction of this display ad format on Google Images, you now have a great opportunity to reach users with engaging ads, whether your goal is to build brand awareness, or to drive clicks and conversions.
