Matching IP addresses to target devices involves leveraging IP-based targeting techniques to identify and deliver advertisements to specific devices within a household or organization. By tracking IP addresses linked to internet activity, campaigns can infer the presence of multiple devices like computers, smartphones, tablets, and smart TVs connected to the same network. Data collection through cookies, device fingerprinting, and third-party databases helps create detailed profiles linked to these IP addresses. This allows campaigns to tailor ads based on voter behavior, demographics, and interests. Utilizing IP matching, campaigns can ensure that their messages reach the right voters at the right time, increasing engagement and driving voter turnout.
