After the deprecation of a third-party cookies, which of these are key inputs for conversion attribution?

The correct answer is AI, contextual signals, and IP address. With the deprecation of third-party cookies, advertisers need alternative methods for conversion attribution. AI plays a crucial role in analyzing various data points and making predictions about user behavior. Contextual signals, such as the content of the webpage or app where an ad is displayed, provide valuable insights into user intent and relevance. IP addresses can offer a level of geographic and network-based identification, which, when combined with other signals, can contribute to attribution models. Privacy-safe integrations are a method for data collection and sharing, not a direct input for attribution models themselves.
