About Smart campaigns on the Google Display Network
Smart campaigns run on both the Google Search Network and the Google Display Network. While the Search Network can reach people when they're already searching for specific goods or services, the Display Network can help you capture someone's attention earlier in the buying cycle. This means you can put your ads in front of people before they start searching for what you offer, which can be key for your overall advertising strategy. For example, you can reach people on the Display Network while they’re browsing their favorite websites, showing a friend a YouTube video, checking their Gmail account, or using mobile devices and apps.
