What are tracking cookies and how do they work?

Tracking cookies send targeted ads to websites you visit in an attempt to persuade you to return to those sites or buy products from advertisers you've clicked on before. To help you learn more, we’ll cover how tracking cookies work, what information they store, and how you can help keep your personal information and browsing activity private by blocking trackers with Norton AntiTrack.

Cookies are small text files that websites save to your browser. There are two main types of cookies: first party and third party. First-party cookies live on the site you are visiting, and third-party cookies originate from a site you aren't currently on.

These files contain data about you and your online browsing activity. When you visit your favorite weather site, for instance, a cookie might remember that you searched for the temperatures in Chicago last week. When you log back on, the site will show "Chicago" as a recommended city for your next weather search.

Tracking cookies are the ones that send targeted ads to websites you visit, with the goal of persuading you to return to sites you've visited in the past or to buy products from advertisers you've clicked on before. 

But are they dangerous? That depends on how much you value your privacy when browsing the web.

How do tracking cookies work? 

Tracking cookies are mostly used for marketing and advertising purposes. The goal is to increase the odds that you’ll purchase a product or service.

Say you are ready to take a road trip to the mountains. You might start searching the websites of communities around your destination. You might also log onto the sites of attractions, restaurants, and hotels in that area.

Then, when you surf your favorite news sites, entertainment blogs, and community sites, you start seeing ads from the same hotels and attractions. This is how third-party tracking cookies work: The sites you visit save them on your browser. They then send targeted ads to you as you scour the internet.

What information do tracking cookies collect? 

Because tracking cookies are mostly used by companies that want to market their products or services to you, they primarily store information about your online browsing activity, including:

• Sites and pages you've visited
• Products you might have clicked on
• Online purchases you've made
• IP addresses
• Geographic location

Again, the goal of collecting cookies is to capture any information that will make it easier for companies to sell you their goods and services. Information such as your IP address and location is especially important for marketers who might want to show you ads for upcoming concerts or events in your area, tickets for your local baseball or football teams, or sales taking place at stores near you.

Are tracking cookies dangerous?

Tracking cookies collect plenty of information about you. But does it make them dangerous? That largely depends on what you consider dangerous. 

Tracking cookies won’t damage your computer or other devices and won’t place malware or adware on them. In that respect, they are safe. But if you don’t want companies, government bodies, news organizations, or social media sites tracking your browsing activity, you might consider tracking cookies a violation of your privacy.

How to block tracking cookies

Fortunately, if you don’t like the idea of cookies tracking your online activity, you can disable them. 

Typically, when you visit any website, it will store at least one cookie—a first-party cookie—on your browser. This cookie remembers your basic activity on the site. When you visit a site for the first time, it will also give you the option to limit cookie activity. 

Some sites will allow you to disable all third-party cookies. If you want to keep your browsing activity away from the eyes of companies and social media sites, select this option when sites give you the choice.

You can also set up your browser so that it will automatically disable third-party tracking cookies. How to do this differs depending on the browser you are using. To learn how to block tracking cookies on your browser, follow these instructions:

Laws regulating tracking cookies 

The days of third-party cookies might be coming to an end. Google, for instance, has announced that it will begin phasing out third-party tracking cookies on its Chrome browser by 2024. That’s big because Chrome is such a widely used web browser.

But it’s not just private companies that are taking steps to limit third-party cookies. Governments, too, have enacted legislation to create civil and criminal penalties for companies, marketers, and others that don’t inform consumers that their websites are using cookies. This includes:

• Europe’s General Data Protection Regulation, or GDPR, which regulates how personal information is collected, stored, used, and eliminated by multinational companies. 
• California’s Consumer Privacy Act, or CCPA, is designed to protect the privacy of California consumers. 

Companies that violate these laws by not telling consumers that their sites are tracking them with cookies can face hefty fines.

Browse the web anonymously with Norton AntiTrack

If you’d like to go beyond tracking cookie removal by disguising your digital fingerprint and surfing the web anonymously, Norton AntiTrack can help. By seamlessly integrating it with your current web browser, you can browse the web in peace without sacrificing privacy or speed.  

FAQs about tracking cookies

If you still have questions about tracking cookies, we’ve got you covered. 

What does “Do Not Track” mean?

Do Not Track (DNT) is an internet browser setting supported by browsers such as Google Chrome and Firefox. When enabled, your web browser will add a DNT header to your web traffic. This will inform websites that you don’t want to be tracked and help prevent you from being tracked by advertisers. 

Are tracking cookies illegal?

No, tracking cookies are not illegal. But, those who use tracking cookies must follow specific privacy regulations, including providing clear information about the cookies, displaying a consent banner, providing the option to separate cookies by their specific type, and the option to deny or revoke consent.

Are tracking cookies spyware?

No, tracking cookies are not considered spyware. This is because tracking cookies are not used secretly and can be easily disabled. On the other hand, spyware is a type of malware that secretly infects your device and is used maliciously to snoop on your personal information.

What happens if I block all cookies?

If you block all cookies, you may notice a change in your browsing experience. For example, you may have to re-input your login details whenever you revisit a site. And sites that usually provide you with tailored information, such as events in your area, will have no idea where you live if all cookies are blocked.
