What type of targeting focuses on delivering ads to users across different devices?

The focus of delivering ads to users across different devices is known as Cross Device Targeting. This method allows marketers to identify and reach the same individual as they move between devices, such as smartphones, tablets, and desktops. This approach enhances the effectiveness of advertising campaigns by ensuring consistent messaging and improving user engagement.

Cross Device Targeting utilizes various technologies and data integration techniques to match users' identities and behaviors, enabling advertisers to create a seamless experience across all platforms. This contributes to improved attribution, as it provides insights into how consumers interact with ads on multiple devices throughout their customer journey.

In contrast, the other options pertain to different advertising strategies. Technical Targeting often involves focusing on specific attributes or behaviors of devices rather than users across multiple devices. Re-Targeting specifically aims to re-engage users who have previously interacted with a brand, primarily on a single device. Geo-Fencing involves targeting users based on their real-time geographic location, which does not inherently account for multi-device behaviors.
