Have you ever searched for a product and then suddenly seen ads for exactly that product on almost every website you visit? Many people feel that the internet is watching them. In fact, behind this there is often a technology known as a “tracker”.
For families, freelancers and small teams this can be confusing. Why do websites seem to know so much about our interests? What data is collected? And how can you better protect your own privacy?
In this article we explain simply and clearly what trackers are, how they work and why they matter for your digital privacy.
What are trackers anyway?
Trackers are small technologies embedded in websites, apps or online services. Their main purpose is to collect information about users’ behaviour.
For example, the following data can be recorded:
- Which websites you visit
- How long you stay on a page
- Which products you look at
- Which links you click on
- Which search terms you use
The information collected is often used to create user profiles. These profiles help ad networks to show the most suitable advertising possible.
Not every tracker is automatically bad. Some help website operators understand which content is popular. Others, however, serve solely to follow users across many different websites.
Why do ads follow me across different websites?
The reason is usually so-called cross-site tracking.
Imagine you visit an online shop and look at new running shoes. An ad tracker is embedded on this website. This tracker stores certain information about your visit.
If you later visit a news website or a blog that uses the same ad provider, the system often recognises you again. As a result, you may be shown ads for exactly these running shoes again.
From the advertising industry’s point of view this is efficient. From the point of view of many users, however, it feels unpleasant or even unsettling.
Families in particular are often surprised at how much data is collected about their online activities. Freelancers and small businesses should also be aware that business research can be used for ad profiles too.
What risks do trackers bring?
Trackers don’t necessarily collect personal data such as names or addresses. Nevertheless, they can build a very detailed picture of your interests and habits.
Possible consequences are:
Less privacy
The more data is collected, the more precisely companies can analyse your behaviour.
More advertising
Trackers mean that users see personalised ads more often. Many find this annoying or intrusive.
Higher security risk
Some trackers come from third parties that are active on thousands of websites. The more external services are embedded, the larger the potential attack surface for cybercriminals becomes.
Strain on devices
Additional scripts and tracking services can slow down websites and cause more data traffic.
How can families, freelancers and teams protect themselves?
Online tracking can hardly be avoided completely. Nevertheless, there are effective ways to significantly reduce data collection.
Use privacy-friendly browsers
Many modern browsers offer built-in protection against known ad and tracking services.
Delete cookies regularly
Deleting cookies can prevent certain tracking information from being stored in the long term.
Check privacy settings
Both browsers and apps often offer options to restrict tracking.
Use DNS-based protection solutions
A particularly convenient solution is to block trackers at network level.
This is exactly where XIBRO SHIELD comes in. The service filters known ad, tracking and phishing domains at DNS level. As a result, many trackers are never loaded in the first place.
For families this means more protection for the devices in the household – up to 30 depending on the plan, and in FAMILIE and ZUHAUSE also via a compatible router. Freelancers benefit from a cleaner working environment without unnecessary tracking. Small teams can improve their digital privacy without having to configure complicated software on every single device.
Another advantage of XIBRO SHIELD: your own IP address stays unchanged. The service works as DNS protection via a WireGuard tunnel and is deliberately not a classic VPN service.
Conclusion: more control over your digital privacy
Trackers are one of the main reasons why ads seem to follow you across the entire internet. They collect information about your online behaviour and help ad networks to create user profiles.
If you want more control over your data, you should learn about online tracking and use suitable protective measures.
With XIBRO SHIELD, families, freelancers and small teams can block many known ad and tracking services in the background and thus improve their digital privacy – without complicated technology and without fundamentally changing their own internet access.
