Jälgimiskoodid

Jälgimiskoodid, often translated as tracking codes or tracking pixels, are small pieces of code embedded in websites or emails that allow for the monitoring of user activity. These codes are typically invisible to the user, often measuring just one pixel by one pixel in size, hence the term "tracking pixel." When a user visits a webpage or opens an email containing a tracking code, the code sends information back to a server.

The information collected by jälgimiskoodid can vary widely. It commonly includes details such as the user's IP address, the time and date of the visit, the browser and operating system used, and which pages were viewed. In the context of emails, tracking codes can reveal whether an email was opened and when, and sometimes even if any links within the email were clicked.

Jälgimiskoodid serve a variety of purposes. For website owners and marketers, they are crucial for analytics, helping to understand user behavior, track the effectiveness of marketing campaigns, and personalize user experiences. Advertisers use them to track ad impressions and clicks, and to build profiles of user interests for targeted advertising. However, concerns about user privacy have led to increased scrutiny and regulation of tracking technologies. Many privacy-focused browsers and extensions offer features to block or limit the use of jälgimiskoodid.
