To prevent cross-site tracking on your Mac, start by understanding what it is. Cross-site tracking is a way for websites to collect data about your browsing habits across multiple sites, often without your knowledge or consent.
This can be done through third-party cookies, which are small files that track your online activities. To limit this, consider disabling third-party cookies in your browser.
One way to do this is by using Safari's built-in features. In Safari, go to Preferences > Privacy > Cookies and website data, and select "Block all cookies".
By taking these simple steps, you can significantly reduce the amount of cross-site tracking on your Mac.
What Are Website Trackers?
Website trackers are scripts that collect information on website visitors' online activities. They can be used to create user profiles for targeted advertisements.
Some common types of web trackers include web beacons, server logs, browser user agents, cookies, flash cookies, and browser fingerprinting.

Web beacons are tiny images embedded in a page or email that notify the server when a page is loaded. This allows advertisers to learn who opened the page and when.
Server logs keep a record of who has loaded a webpage, when, the user journey to the page, and the visitor's IP address. This information can be used to identify users across multiple websites.
Browser user agents are mini-applications that show information about the web browser and the user's operating system. Advertisers collect this information to create a picture of the visitor and their online habits.
Cookies are the most well-known tracking technology, and they're a string of code saved to your device. Websites can see the cookie and recognize if you've previously visited or not.
Here are some common types of trackers:
- Web beacons: tiny images embedded in a page or email
- Server logs: records of who has loaded a webpage, when, and the user journey
- Browser user agents: mini-applications that show information about the web browser and operating system
- Cookies: strings of code saved to your device
- Flash cookies: sophisticated version of regular cookies
- Browser fingerprinting: identifies users by custom browser settings or other features
Flash cookies are a more sophisticated version of regular cookies, and they can even restore deleted information. Browser fingerprinting creates a unique portrait of the user to help websites identify them.
How Websites Work
Websites track your browsing behavior by embedding widgets, scripts, or tiny images on the sites you visit. These trackers log every activity, creating a trail of data that can be used to build user profiles.
Social media buttons are often embedded on websites to gain analytics, but they also send your data back to those platforms for targeted advertisements.
Most websites use web tracking systems and trackers to monitor user activity. Some of the most commonly used systems include.
These trackers are often hidden from view, but they're always working behind the scenes to collect your data.

Understanding Site Tracking
Site tracking is a sneaky way for companies to monitor your online activity across multiple websites. This can include your browsing habits, navigation, and even your IP address.
Some websites use scripts or place files called cookies on your device to uniquely identify you and send information back to the source. Advertisers can then use the harvested data to present you with targeted ads.
Web beacons, like the Facebook Pixel, are also used to track user behavior and monitor browsing habits. They can even log the exact time and date you open an email embedded with a beacon.
Here's a quick rundown of some common ways sites track you:
What Is Site?
Site tracking is a common practice where companies monitor your activity across multiple websites.
Web beacons are used by websites to log user behavior, similar to cookies, and can track almost every aspect of your web browsing activity.
The Facebook Pixel is a well-known example of a web beacon that tracks your browsing habits and helps advertisers show you targeted ads.
You may have seen targeted ads that seem eerily relevant to you, and this is likely due to some form of tracking.
Companies use scripts or place files called cookies on your device to uniquely identify you and send information back to the source.
Advertisers can then use the harvested data to present you with targeted ads, making you feel like they're watching your every move.
Canvas Fingerprinting
Canvas Fingerprinting is a sneaky way websites can identify you. They do this by making your browser draw a hidden image, which is unique to your device.
This technique uses HTML5, the latest version of the coding language HTML. HTML5 was developed for animations and drawing graphics, but it's also got a dark side – it can be used for tracking and fingerprinting.
The unique image created by canvas fingerprinting is like a digital fingerprint, and it can provide accurate information when combined with other tracking data. Think of it like a fingerprint – it's unique to you and can be used to identify you.
Websites with this feature can use it to track your online activities, and it's often used in conjunction with other tracking methods.
