Tracking cookies plays a major role in how websites gather data and deliver personalized experiences. Whether you’re a site owner looking to optimize marketing efforts or a curious user concerned about privacy, understanding how tracking cookies works is essential.
In this guide, we’ll break down what tracking cookies are, how they’re used, what kind of data they collect, and what that means for your privacy. We’ll also walk you through how to manage or block them—and how to stay compliant with major privacy laws like the GDPR and CCPA.
Let’s dive in.
Key Takeaways:
- Tracking cookies are small files used by websites to track user behavior, personalize content, and deliver targeted ads.
- While they enhance user experience and marketing performance, they also raise privacy concerns and are regulated under laws like GDPR and CCPA.
- Website owners must obtain proper consent before using tracking cookies, and users can manage or block them through browser settings.
Tracking cookies are small text files that websites place on a user’s browser to collect data and track their activities. These cookies track users’ activity and process this information to help websites show personalized recommendations and targeted ads.
Tracking cookies collects information such as shopping preferences, device specifications, location, and browsing behavior. This information is used for gathering website analytics and showing targeted advertisements.
When it comes to tracking cookies, we can break them down into two main types: first-party tracking cookies and third-party tracking cookies.
First-party tracking cookies are those little bits of data that the website owner places on a visitor’s browser while they’re exploring the site. These cookies help website owners gather information about how visitors are interacting with their site, tracking things like online behavior, preferences, and interactions. This data is invaluable for understanding clicks, impressions, and bounce rates.
On the other hand, we have third-party tracking cookies. These are set by external services while you’re browsing a website. Advertisers, marketers, and various external services use these cookies, often in conjunction with display ads or social media plugins.
Many websites add external resources, like social media widgets or analytics tools, from third-party providers. These resources are integrated into the site through HTML tags or JavaScript code supplied by the third-party service. So, when you visit a website, your browser also loads these external resources, which in turn sets those third-party cookies.
Tracking cookies operate by placing a unique identifier on a user’s web browser as they explore various websites. These identifiers are made up of a mix of letters and numbers, and they’re generated by the websites themselves or by third-party services.
When a user lands on a site that employs tracking cookies, the server of that site sends a cookie to the user’s browser, which then saves it on their device. The next time the user returns to that site, their browser sends the saved cookie back to the server.
This process allows websites to recognize users who come back, monitor their activities, and collect information like browsing history, preferences, and interactions.
Tracking cookies collects a variety of information from visitors to websites, all aimed at personalizing content, enhancing user experience, and enabling targeted advertising. Here’s a breakdown of what they collect:
- Browsing history: These cookies keep track of the websites users visit, noting which pages they view and how long they stay on each one.
- Preferences: They also collect data on user preferences, like language choices and font size settings.
- IP address: Tracking cookies capture users’ IP addresses, which can reveal their approximate geographical location and the internet service provider they use.
- Interactions: They monitor how users interact with websites, including clicks, scrolling behavior, and form submissions.
- Shopping history: Tracking cookies follow users’ online shopping habits, such as the products they view, what they add to their cart, and their previous purchases.
- Device specifications: They gather information about the user’s device, including the type of device, operating system, screen resolution, and browser version.
These are just a few examples of the data that tracking cookies can collect. The specifics can vary based on factors like the website’s features, the types of cookies in use, the site’s cookie policy, any external services involved, and the consent given by users.
Let’s explore a bit more about how websites use tracking cookies.
1. Personalized Content
Websites use tracking cookies to deliver personalized content to users based on their preferences and browsing behavior. This includes customized product recommendations on eCommerce websites, personalized movie shows by streaming platforms, etc.
2. User Authentication
Tracking cookies helps websites recognize returning users and remember the user credentials for authentication. This enhances user convenience and facilitates seamless access to account features and personalized content.
When you choose the “Remember Me” or “Keep me logged in” option on a website, a cookie is often set in your browser to store your login credentials securely. This allows the website to recognize you and automatically log you in the next time you visit without requiring you to re-enter your username and password.
3. Website Analytics
Websites use tracking cookies to gather analytics and insights on users’ interactions with the website. This includes user engagement, navigation patterns, heatmaps, etc. This helps website owners to optimize their sites for a better user experience.
4. Targeted Advertising
This is one of the most controversial uses of tracking cookies by websites. Websites use tracking cookies to show targeted advertisements to users. They track users’ online activities across different websites to build profiles and deliver personalized advertisements based on their interests, demographics, and browsing history. This allows advertisers to target specific audiences with relevant ads, potentially increasing ad engagement and conversion rates.
5. Remarketing Campaigns
Websites use tracking cookies to show ads to users who have previously visited their site but did not complete a desired action, such as making a purchase. By retargeting these users with relevant ads, websites can encourage them to return and complete the purchase.
6. Website Customization
Tracking cookies are also used to customize the user experience based on their location, device type, or language preferences. This includes displaying localized content, optimizing the website layout for different devices, and providing translated versions of the website.
Tracking cookies are not necessarily dangerous, but it raises some serious privacy concerns. You may have noticed ads on your social media platforms that seem directly related to recent searches on sites like Amazon, which can understandably make users feel uneasy about their privacy.
Tracking cookies can create digital footprints of users’ online activities. It leaves behind a trail of information that could lead to track and identify the user. Moreover, they may contain personally identifiable information, posing a risk to users’ privacy and security.
When used responsibly, tracking cookies can be beneficial for both website owners and visitors. It helps websites to show personalized recommendations and gather valuable website analytics. Additionally, they enhance user experience by allowing visitors to view content according to their preferences and conveniently save login information.
We have already said that tracking cookies may carry personally identifiable information such as IP addresses, so it raises some privacy concerns. Let’s have a look at major privacy laws and their provisions regarding tracking cookies.
GDPR and Tracking Cookies
As per the EU’s General Data Protection Regulation, websites using tracking cookies should obtain explicit consent from site visitors before loading them into their web browsers. The consent should be freely given, specific, informed, and with clear affirmative action.
GDPR also gives users the right to withdraw their consent at any time. So, website owners should provide users with the option to manage their consent preferences.
Also, it is important to state the purpose and the details of the cookies used on the website. If you are a website owner, you can use any consent management platform to create a GDPR-compliant cookie banner on your website. Using a cookie banner, you can disclose the use of cookies and provide users with the option to manage their consent preferences.

CCPA and Tracking Cookies
The California Consumer Privacy Act requires an opt-out consent mechanism for using cookies and third-party scripts. Websites need not obtain prior consent for using cookies to track users. Instead, they should provide a clear and distinct “Do Not Sell My Personal Information” link on their website to allow consumers to submit an opt-out request.
Websites should obtain consent from the site visitors to use tracking cookies. The best way is to use a consent management platform to manage cookie consent for your website. If you are using WordPress CMS, check out our GDPR cookie consent plugin for your consent management requirements.
GDPR Cookie consent plugin is a CMP native to WordPress, so it will work on your own server, and any consent-related data will not be shared with external servers. Using the plugin, you can completely manage cookie consent for your website.
Following are the steps you should follow to ensure cookie compliance:
- Create a cookie consent banner to disclose the use of cookies and their purpose
- Provide users with the option to accept and decline cookies
- Allow users to provide granular consent to cookies based on their categories
- Create a cookie policy and privacy policy and add the links to the cookie banner
- Allow users to withdraw and revisit the consent at any time
- Keep a record of users’ consent
- Block third-party cookies until the user gives consent
As an end user, you may want to block tracking cookies from your browser. Let’s see how you can block cookies on different browsers.
Block Cookies on Google Chrome
- Click on the three vertical dots in the upper right corner near your profile icon.
- Go to the Settings menu.
- Once you are on the Chrome Settings page, go to the Privacy and security tab and select Third-party cookies.
- Click on the Block third-party cookies radio button to block cookies. Additionally, you can enable the Send a ‘Do Not Track’ request with your browsing traffic checkbox.
Block Cookies on Safari
Safari, by default, blocks third-party cookies. However, you can ensure it from the following steps:
- Go to Safari > Settings from the top menu bar.
- Then click on the Advanced tab.
- Enable the Block all cookies checkbox.
Block Cookies on Firefox
Firefox provides users with three privacy settings options: Standard, Strict, and Custom. In all three settings, third-party cookies are automatically blocked. However, with the Custom option, you have the flexibility to select the types of cookies you want to allow.
To access these settings in Firefox:
- Click on the menu bar and go to Firefox > Preferences.
- Choose the Privacy & Security tab.
- Choose the Custom option and select the trackers or scripts you want to block.
Block Cookies on Microsoft Edge
Microsoft Edge provides users with three levels of privacy settings: Basic, Balanced, and Strict. Strict offers the highest level of security and blocking.
To access these settings in Microsoft Edge:
- Click on the three horizontal dots next to your profile icon and choose Settings.
- Navigate to the Privacy, Search, and Services tab.
- Under Tracking Prevention settings, select Strict.
Not anymore. Google has officially stepped back from its original plan to completely phase out third-party cookies in Chrome. Instead of blocking them by default, Chrome users will now have the choice to allow or block these cookies manually.
This decision has stirred up some controversy, especially among privacy advocates and regulators. Groups like the UK’s Competition and Markets Authority (CMA) and the Information Commissioner’s Office (ICO) have criticized Google for delaying stronger privacy protections and putting user data at continued risk.
Originally, Google planned to replace third-party cookies with a privacy-first alternative through its Privacy Sandbox initiative. But now, with this shift in direction, it seems like advertisers and websites will continue relying on traditional tracking methods—at least for the foreseeable future.
A Consent Management Platform (CMP) is a tool that enables websites, publishers, and organizations to collect and manage user consent for processing their personal data. It helps websites to comply with data privacy laws such as GDPR and CCPA.
When a visitor lands on a website, they might see a popup or banner asking for consent to load cookies on their browsers. This popup or banner is provided by a CMP integrated into the website. Once a consent signal is received from the users, the website will be able to display ads from the vendors to the users.
As of now, tracking cookies is not illegal. However, their usage is subject to data privacy regulations and consent requirements in various jurisdictions. Websites using tracking cookies should comply with the applicable regulations and obtain consent from users. Failure to do so can result in penalties or legal action for violating users’ privacy rights.
It’s important for businesses to stay informed about the legal requirements related to tracking cookies.
No, not if you’re operating in regions governed by privacy laws like the GDPR or CCPA. These regulations require websites to obtain clear, informed consent before placing tracking cookies on a user’s browser, especially if the cookies are used for advertising or analytics purposes.
First-party cookies are set by the website you’re visiting and help with things like remembering login details or user preferences. Third-party cookies, on the other hand, are set by external services like ad networks or social media plugins and are primarily used for cross-site tracking and personalized advertising.
Tracking cookies is a powerful technology that helps advertisers and marketers to track users and gain valuable insights on their websites. It also helps website visitors to view personalized content and save their preferences.
However, tracking cookies also raises some privacy concerns. Many data protection laws require websites to obtain prior consent from their visitors for using cookies.
Google is also planning to phase out tracking cookies and introduce a privacy-focused alternative that will enable websites to show personalized ads while protecting the privacy of individuals.
The emergence of these technologies signals a positive shift towards a safer digital environment.
