Preventing cross-site tracking is a crucial step in protecting user privacy and staying compliant with regulations. The General Data Protection Regulation (GDPR) requires websites to obtain explicit consent before collecting or sharing user data.
To comply with GDPR, websites must implement measures to prevent cross-site tracking, such as using cookies that are deleted after each session. This approach ensures that user data is not stored for extended periods.
The GDPR also mandates that websites provide users with clear information about data collection and use. This transparency is essential for building trust with users and maintaining compliance.
What is Cross-Site Tracking?
Cross-site tracking is a process that relies on cookies, small data files stored on users' browsers. These cookies can be used to track users' activities across multiple websites.
Websites use first-party cookies to remember user preferences and settings, which is helpful for a seamless browsing experience. However, third-party cookies, set by domains other than the visited site, are what enable cross-site tracking.
Third-party cookies are used by advertising networks and analytics firms to track users' activities, which can be used for targeted advertising. This means that even if you're browsing a website that you trust, you might still be tracked by third-party cookies.
Cross-site tracking also involves session replay scripts that record and analyze user behavior on websites. This data can be used to create personalized experiences, but it can also be used to target you with ads.
Here's a quick breakdown of the cross-site tracking process:
- Cross-site tracking relies on cookies (or similar)
- Websites use first-party cookies to remember user preferences and settings
- Third-party cookies, set by domains other than the visited site, extend tracking across multiple websites
- Advertising networks and analytics firms utilize third-party cookies to track users' activities
- Session replay scripts record and analyze user behavior on websites
Types of Cross-Site Tracking
Cross-site tracking methods are numerous, but four common practices stand out.
Third-party cookies are commonly used by advertising networks and analytics companies to track users across multiple websites. They can be embedded in advertisements or included in website elements such as social media buttons.
How Cross-Site Tracking Works
Cross-site tracking is done through the use of cookies, beacons, and scripts that are woven into website code. Cookies are the best-known example, containing unique identifiers stored in our browsers and carried across different website pages.
Cookies aren't the only tool used for cross-site tracking, though - pixel tags or web beacons can also collect data on browsing activities and create comprehensive profiles with remarkable precision.
These tools allow advertising networks to monitor user activity across devices, and by analyzing browser configurations, plugins, and other device-specific information, they can create unique digital fingerprints for each user. This allows them to track behavior better across devices and create a "backup" profiling strategy when cookies aren't an option.

How to Track
Cross-site tracking is a real concern, but fortunately, there's a way to prevent it. With the advancement of technology and growing awareness, developers have created options to block or disable cross-site tracking.
You can prevent cross-site tracking by using available technology.
Developers have realized the several security risks cross-site tracking presents, and they're taking steps to address them.
Cross-Site Tracking Security
Cross-site tracking security is a major concern, as it can pose a huge security risk. This type of tracking allows third-party sites to access your online activity, which can be misused to cause harm.
If a webpage is hacked or compromised, the hacker can gain access to the site tracking feature and view your online activity, including passwords and confidential credentials. This is not a hypothetical scenario, as it's a real possibility.
To mitigate this risk, you can enable browser privacy options, such as blocking third-party cookies or disabling tracking. This can be done in most popular browsers, including Chrome, Safari, Firefox, and Edge.
Here are some steps you can take to prevent cross-site tracking:
- Block third-party cookies to prevent tracking
- Disable tracking in your browser settings
- Install anti-tracking extensions, such as Privacy Badger or Ghostery
What Is CSRF?
Cross-site tracking raises concerns about user privacy, data security, and consent. This is because it involves monitoring and recording users' online activities across different websites and online platforms.
The primary objective of cross-site tracking is to collect data about users' browsing behavior, interests, and preferences. This data can then be used for targeted advertising, analytics, website optimization, and personalization.
Cross-site tracking can offer benefits in terms of improving user experiences and enabling personalized content. However, this comes at the cost of compromising user trust and potentially exposing users to security risks.
The benefits of cross-site tracking may seem appealing, but it's essential to consider the potential risks and consequences. By understanding these risks, we can take steps to protect our online privacy and security.
Cross Site Security
Cross Site Security is a serious concern. You see, cross-site tracking can be extremely helpful, but it also displays a huge security risk.
Your data is recorded without your understanding or consent, and it's available to anyone. This includes first-party webpages that can forward your data to third-party sites, which can misuse your information and cause harm.
If a webpage is hacked or compromised, the hacker will gain access to the site tracking feature and view your online activity, including your passwords and confidential credentials. This is a huge risk, and it's essential to take precautions.
Fortunately, browsers offer dedicated options to block third-party cookies, disable tracking, and limit data collection. You can enable these options in your browser to prevent cross-site tracking.
Here are some ways to prevent cross-site tracking:
- Enable browser privacy: Whether you have Chrome, Safari, Firefox, or Edge, browsers offer dedicated options to block third-party cookies, disable tracking, and limit data collection.
- Install anti-tracking extensions: Extensions like Privacy Badger, Ghostery, or uBlock Origin were built to block trackers and prevent cross-site tracking.
- Opt-out of targeted advertising: Users can manually opt-out of targeted ads to reduce the amount of data collected. Tools like Enzuzo's consent manager can help companies manage this at scale.
Frequently Asked Questions
What is cross-site tracking prevention on iPhone?
Safari on iPhone has a built-in feature called Prevent Cross-site Tracking that blocks data sharing across websites, but it also clears cookies and website data each time you visit a new page. This setting is enabled by default, but you might want to know more about how it works and when to disable it.
How do I stop cross-site tracking on my Android phone?
To stop cross-site tracking on your Android phone, go to Settings > Privacy and security > Send a "Do Not Track" request. If you're part of the Tracking Protection test group, follow the separate instructions for that feature.
