Tracking pixel

A tracking pixel is a small piece of code placed on a website or within an email that allows businesses to collect information about user behaviour. It works by loading a tiny, invisible image when a page or email is viewed, which sends data back to an analytics or advertising platform.

Tracking pixels help marketers understand how people interact with digital content.

Tracking pixels provide insight into how users behave after seeing an advert, visiting a website, or opening an email. This information helps businesses measure the effectiveness of their marketing campaigns.

Tracking pixels help businesses:

  • Track website visits and user activity
  • Measure advertising performance
  • Understand customer behaviour
  • Support remarketing and audience targeting

How tracking pixels work

When a tracking pixel is placed on a webpage or email, it loads automatically when the page or message is opened. When it loads, it sends information such as the time of the visit, the device being used, and the page viewed back to the platform that issued the pixel.

This data allows marketers to see how users interact with content and campaigns.

Tracking pixels in digital advertising

Advertising platforms often use tracking pixels to measure conversions and campaign performance. For example, a pixel placed on a website can record when a visitor completes an action such as making a purchase or submitting a form.

This information helps advertisers understand which campaigns or adverts contributed to the outcome.

Tracking pixels and remarketing

Tracking pixels are commonly used in remarketing campaigns. When someone visits a website, the pixel records that interaction. Advertising platforms can then show adverts to those users later as they browse other websites or social media platforms.

This helps businesses re-engage people who have already shown interest.

Tracking pixels and data privacy

Because tracking pixels collect behavioural data, businesses must handle this information responsibly. Many websites now use consent banners and privacy policies to inform visitors about tracking technologies and allow them to manage their preferences.
