What is cross-site tracking?

Cross-site tracking is the practice of businesses, advertisers, and other entities tracking you across multiple websites in order to monitor your browsing habits. Companies may have multiple reasons for wanting to analyze your online activity, including product improvement, targeted advertising, and personalizing the user experience.

While cross-site tracking is marketed as an innocuous act, some consider the practice a breach of privacy, especially when websites fail to seek consent. On top of that, few companies offer easy-to-understand information about what they will and won’t do with the data they collect. Unless you’re willing to study the privacy policies of every site you visit, knowing where your data will end up is difficult.

How cross-site tracking works

Cross-site tracking often works by planting a small file known as a cookie in your browser. That file remains on your device until removed, monitoring your activity and relaying data back to the company who placed it. While third-party cookies are common tracking tools, other methods do exist.

For example, companies can also use social media like, share, and comment buttons to track you across any websites that use those features. If you’re logged into your social media accounts, those platforms can connect your browsing habits to your profiles. Evidently, cross-site tracking commonly occurs behind the scenes without your knowledge or consent.

What are trackers on a website?

Websites use tracking tools, such as cookies and scripts, to collect data on your browsing activity. While companies must implant cookie files into your browser, invisible scripts can run in the background of visited pages, logging your IP address, device specifications, and other identifying information.

How to prevent cross-site tracking

As the importance of online privacy grows more obvious, developers are taking steps to give you more control over your private data and prevent practices like cross-site tracking. Almost all modern browsers come with tools to help stop trackers from monitoring and logging your activity without your consent. How protected is your private data in your current browser? A quick check of the settings will let you know.

Stop browser tracking in Chrome

Here’s how to stop cross-site tracking in the Chrome desktop app:

1. Click the More options button in the top right corner and select Settings.

2. Go to Security and Privacy > Cookies and other site data.

1. Tap the More options button in the top right corner and select Settings.

2. Tap Privacy and security.

3. Tap ‘Do Not Track.’

4. Toggle the setting On.

Alas, Google’s Do Not Track feature doesn’t actually block trackers. Switching the setting on simply requests that websites don’t perform any tracking, which means anyone, including Google itself, can choose to ignore the request.

If you’re serious about stopping cross-site tracking in the Chrome desktop app, VeePN’s browser extension blocks most trackers and grants you control of your private data.

Here’s how you can use VeePN to prevent cross-site tracking in Chrome:

Does a VPN prevent cross-site tracking?

While a VPN by itself doesn’t prevent cross-site tracking, you can use one to confuse trackers by connecting to a server outside of your actual location. A VPN will also encrypt your traffic and stop your ISP and other organizations from spying on your connection. However, if you want to stop cross-site tracking completely, you should choose a VPN service that includes tracker blocking.

A top-tier VPN, such as VeePN, must have anti-tracking protection. To block trackers once and for all, you should:

1. Download and install VeePN.
2. Go to Privacy Preferences.

3. Tick PureWeb to stop trackers.

4. Turn VPN On.

That’s really all there is to it. While companies collecting private data has never been more common, protecting your privacy online has never been easier. VeePN certainly makes it simple.

Take back control of your privacy

Websites and other online platforms aren’t going to stop harvesting your data any time soon, but that doesn’t mean you have to forfeit your privacy. The anti-tracking features included in most modern browsers are worth enabling.

However, for extra protection, you should consider adding a VPN to your security toolbox. A solid VPN service, such as VeePN, will provide all of the privacy features and tracker prevention tools you could ever need. You don’t need to pass on your private data for the profit of others. Today’s the day to take back control.
