Verkkojäljityspikselit, often translated as "tracking pixels" or "tracking codes," are tiny, transparent images embedded in web pages or emails. Their primary function is to collect data about user behavior. When a user loads a web page or opens an email containing a tracking pixel, the pixel makes a request to a server, which in turn records information.

This recorded information typically includes details such as the IP address of the user, the time of the visit, the type of browser used, and which pages were viewed or which emails were opened. The data collected by these pixels is often anonymized, meaning it's not directly linked to an individual's identity, although in some cases it can be combined with other data to identify users.

Tracking pixels are widely used in digital marketing and website analytics. They help businesses understand user engagement, measure the effectiveness of advertising campaigns, and personalize content. For example, a company might use a tracking pixel to see how many people clicked on an online advertisement and then visited their website.

However, the use of tracking pixels has also raised privacy concerns. Critics argue that they allow for extensive user tracking without explicit consent, potentially leading to a lack of transparency in how personal data is collected and used. Regulations like the General Data Protection Regulation (GDPR) in Europe and the California Consumer Privacy Act (CCPA) in the United States have introduced stricter rules regarding the use of tracking technologies, requiring websites to obtain consent from users before placing cookies or employing tracking pixels.
