seurantapikseliä

Seurantapikseli, often translated as tracking pixel or tracking dot, is a tiny, typically one-pixel transparent image embedded in a webpage or email. Its primary function is to track user activity. When a user views a webpage or opens an email containing a seurantapikseli, the pixel is loaded from a server. This loading action sends information back to the server, indicating that the page or email has been accessed.

The data collected by a seurantapikseli can include the IP address of the user, the time of access, the type of browser used, and the specific webpage or email that contained the pixel. This information is often used for website analytics, measuring advertising effectiveness, and understanding user behavior. For example, a company might use a seurantapikseli in an email to determine if a marketing campaign has reached its audience and if recipients are engaging with the content.

In the context of online advertising, seurantapikselit are frequently employed for retargeting. This allows advertisers to show ads to users who have previously visited their website or shown interest in their products. While useful for businesses, the use of seurantapikselit has raised privacy concerns due to the data collection capabilities. Users may be unaware that their online activities are being monitored by these invisible pixels. Many web browsers and email clients offer settings to block or limit the use of tracking pixels to enhance user privacy.
