Crosspixel

Crosspixel is a term used in digital advertising to describe the process of targeting or retargeting users across different websites and platforms based on their past online behavior. It involves collecting data on a user's browsing habits, such as the websites they visit, the products they view, and the searches they perform, and then using this information to display relevant advertisements to them on other digital properties.

The core concept behind crosspixel is the use of tracking pixels or cookies. These are small pieces of code embedded on websites that record user activity. When a user visits a website with a crosspixel, their browser is assigned a unique identifier. This identifier is then recognized by advertising networks when the user visits other websites that are part of the same network. This allows advertisers to serve ads that are personalized to the user's interests, even if they are no longer on the original website.

Crosspixel advertising aims to increase the effectiveness of ad campaigns by reaching users at multiple touchpoints in their online journey. It is a common strategy for retargeting, where advertisers try to re-engage users who have previously shown interest in their products or services. While effective for advertisers, concerns have been raised regarding user privacy and the potential for intrusive tracking. Regulations like GDPR and CCPA have introduced measures to give users more control over how their data is collected and used for crosspixel purposes.
