Cookies make the internet go round. Without them, the modern age of the internet would look a lot different.
Can you imagine online shopping without saving items in your cart or YouTube without video recommendations based on your viewing history?
Cookies are what makes that possible.
As a website owner, you need to know the function of cookies and be able to implement them for your website to operate efficiently and competitively.
But you must do it legally.
Our tracking cookies guide will give you the information you need about tracking cookies, how they work, and your responsibilities when using cookies on your website.

What Are Tracking Cookies?
Internet cookies are small bits of data that get saved onto a user’s computer. They are made up of collected data about the user and their browsing activity, and you can use them to remember your users’ preferences to enhance their online experience.
Tracking cookies are a type of internet cookie used primarily for advertising purposes.
As a user surfs the web, the cookies follow them, keeping track of information about the user’s preferences, habits, past website visits, and purchases.
With this information, you can send advertisements to the user and show them the products and services they’re most likely interested in — among other actions.
What Are Third-Party Tracking Cookies?
Most tracking cookies are third-party tracking cookies. Unlike first-party tracking cookies, which are placed on a website by the website operator to track a user’s activity, third-party tracking cookies are put on a website by other services — such as Facebook — to track visitor activity.
Third-party tracking cookies are a handy and standard tool used for advertising. By collecting information about a user, you can enhance their online experience.
These tracking tactics, however, can be a double-edged sword, and you will have to balance the benefits of tracking cookies with your users’ concerns about data privacy.
How Do Tracking Cookies Work?
Now that you know what tracking cookies are, how do they work?
When a user visits your website, you can place a third-party tracking cookie on their device. This cookie will follow the user as they surf from website to website and collect any personal information about them.
The tracking cookie can store:
- Which websites the user visited
- The web pages on those websites
- Any products purchased
- Any other advertisements the user clicked on, and more.
You can then use this information to tailor marketing campaigns to the specific user.
Are Tracking Cookies Bad or Dangerous?
Generally, tracking cookies do not harm a user’s device, nor do they detract from their online experience.
Despite this, tracking cookies have become a concern with users and governments.
Many people have grown uncomfortable with the idea that website operators are following them and storing their data. It is one thing for a website to save passwords or recommend past purchases on the next login, but keeping location and tracking habits across websites has begun to feel more invasive than helpful for some users.
This change in user perception does not mean you have to stop using cookies on your website, but being aware of your web users’ concerns can help you to better connect with them and find ways to be more transparent.
Are Tracking Cookies Illegal?
Using tracking cookies is not illegal, but using them out of compliance with data privacy laws and without user consent can be. Additionally, compliance with the data privacy regulations will give your website users more faith in your business and trust in your brand.
Are Tracking Cookies Dangerous to Your Visitors?
Unless they have been laced with a virus or some malware or spyware, tracking cookies are not harmful or dangerous to visitors. They will not damage your website, nor will they damage the device your user is operating.
Some of the control that cookies have can be helpful to brands and users alike. For example, a past purchase list on a website helps a user save time by not having to search for the same product again.
But some website users view the collection of search inquiries and locations as an invasion of privacy. So to protect user information and prevent this data from getting into the wrong hands, many governments have implemented their own laws controlling the use of tracking cookies.
Generally speaking, these laws allow tracking cookies on your website as long as your users consent to their use.
What Data Do Tracking Cookies Store?
Cookies can store various bits of personal information from your users. Most of this information gets used to improve advertisement targets.
Common pieces of personal information collected include:
- Type of device the user used (e.g., computer, tablet, mobile phone)
- Name and age
- Website preferences, themes, and settings (language, notifications, time zone)
- IP address
- Email address and passwords
- History and prior purchases
- Time spent on webpages
- Browsing history
- Websites visited
- Advertisement interactions and clicks
- Search engine inputs
Examples of Tracking Cookies Usage
When operating your website, you must know what to use tracking cookies for to improve your website operations.
Here are three common examples of tracking cookies usage:
- Example 1: A user visits a rock band’s website and then goes to their social media page. The next day the user sees an advertisement to buy tickets to the band’s concert in their city. Tracking cookies followed the user and learned the user’s location via IP address and their interest in the band.
- Example 2: A user searches for slippers on Amazon. The next day, on the corner of the user’s email homepage, there are slipper advertisements from Amazon.
- Example 3: A user searches for plane tickets to Prague for a summer vacation. The next day the user sees advertisements for hotels in Prague.
How Data Privacy Laws Regulate Tracking Cookies
As a website owner, you must be aware of the data privacy laws you may be subject to because penalties for violating these laws tend to be steep.
These are a few of the most common data privacy laws your business will likely need to comply with:
How the ePrivacy Directive Regulates Tracking Cookies
It’s also often called the “EU Cookie law.”
You are subject to this law if any of your users are residents of a country that is a member of the European Union, Island, Norway, Liechtenstein or Switzerland.
One of the main focal points of the legislation is that it requires you to obtain user consent before you use cookie trackers on your website to collect their personal data.
For consent to be valid, you must provide the user with “clear and comprehensive information…about the purposes of the processing.”
How the GDPR Regulates Tracking Cookies
The General Data Protection Regulation (GDPR) is one of the major data privacy laws you need to comply with, and it is also one of the strictest.
Passed by the European Union in May 2018, the GDPR was enacted to create a uniform data privacy law for the European Union and to provide a way for residents of the EU to protect their personal data.
Under the GDPR, you must get user consent to process a user’s personal data, which includes personal data collected from tracking cookies.
Personal information can be:
- Identification number
- IP address
- Person’s physical, physiological, genetic, mental, economic, cultural, or social identity
The GDPR also provides users a way to have their personal information erased. Article 17 of the GDPR states that users have “the right to be forgotten.” Subject to certain exceptions, users have the right to have you delete their personal information.
How the CCPA Regulates Tracking Cookies
The California Consumer Privacy Act (CCPA) is another major data privacy law. It was passed by the legislature of California in June 2018, and its purpose is to protect the personal data of the residents of California.
While the CCPA does not have a consent requirement, you must explain to your users — if they’re California residents — what personal information you will collect and why you will collect it.
Under the CCPA, personal information includes:
- Direct identifying information like name, email address, social security number
- IP address
- Internet browsing history and past purchases
To comply with CCPA, you must provide users with the reason you collect the information and an opt-out mechanism before collecting their personal information or using any tracking cookies.
Additionally, if you are using cookies to sell data, you need to give users an easy way to opt out of the sale of their personal information via a “Do Not Sell My Personal Information” link.
How the LGPD Regulates Tracking Cookies
The Lei Geral de Proteção de Dados Pessoais (LGPD) is Brazil’s data privacy law that was enacted in August 2020. You must abide by this regulation if you use tracking cookies and collect and process data from users in Brazil.
Under the LGPD, you can only process personal data with the user’s consent. Consent must be given in writing or “by other means able to demonstrate the manifestation of the will of the data subject.”
This law separates personal data from sensitive personal data, but the collection of either requires user consent before that data can be used for tracking and processing.
Personal data includes information relating to an identified person or an identifiable person and sensitive data includes:
- Data concerning race or ethnic origin
- Political opinion
- Trade union
- Organizational membership
- Data on health status or sex life
- Data on genetics or biometrics
How the POPIA Regulates Tracking Cookies
The Protection of Personal Information Act (POPIA) is a data protection law enacted by the South African government in June 2021. It mandates user consent for you to be permitted to process the personal information of its residents.
The POPIA defines consent as “any voluntary, specific and informed expression of will in terms of which permission is given for the processing of personal information.”
Personal information is defined as:
- Demographic information (race, gender, sexual orientation, ethnicity, national origin, social origin, or age
- Physical and mental health
- Disability status
- Culture, religion, and language
- Education status
- Financial status
- Employment history
- Criminal record
- Identifying number or other information (physical address, email, IP address)
- Biometric information
- Private correspondence
- Personal opinions, views, or preferences
How the PIPL Regulates Tracking Cookies
The Personal Information Protection law (PIPL) was enacted in China in November 2021 as China’s equivalent of Europe’s GDPR.
The PIPL applies to your website no matter where you are located, as long as you collect the personal information of the inhabitants of China.
This regulation protects a user’s personal information only from the private sector, not from the Chinese government.
Under PIPL, sensitive personal information is defined as:
- Information on biometrics
- Specifically designated status
- Religious beliefs
- Mental health
- Financial status
- Location tracking
- Any information regarding a minor under 14 years old
PIPL confers the following rights:
- Right to know what businesses will do with their personal data
- Right to decide on, prohibit, or restrict the use of their personal data
- Right to access and copy their personal information
- Right to correct and supplement their personal information
- Right to data portability
- Right to have their personal information deleted
Under the PIPL, you must obtain a user’s consent before you process their data.
The PIPL defines consent as permission given “under the precondition of full knowledge, and in a voluntary and explicit statement.” Therefore, users must voluntarily give consent in an explicit statement after being given the knowledge about how you will use their personal information.
This consent can be rescinded at any time and you must provide an easy-to-understand method for your users to withdraw their consent.
Other reasons you may process the personal data of your users include the following:
- To fulfill contractual obligations
- Human resource management
- Comply with statutory duties or obligations
- Public interest
- Individuals already disclosed their personal information
How PIPEDA Regulates Tracking Cookies
The Personal Information Protection and Electronic Documents Act (PIPEDA) is the data privacy law of Canada, passed in 2001. PIPEDA applies to businesses in the private sector in Canada that collect, use, or share personal info when performing a commercial activity.
Under PIPEDA, you must obtain implicit or explicit meaningful consent to collect, use and share the personal data of your users.
PIPEDA defines personal information as “information about an identifiable individual,” and can include:
- Name, age, ad identification numbers
- Ethnic origin
- Blood type
- Financial and social status
- Evaluations, opinions, and comments
- Disciplinary actions
- Employment records
- Health information
- Credit and loan records
How COPPA Regulates Tracking Cookies
While the United States does not have a federal data privacy law, it does have a law that protects the data and online privacy of children. The Children’s Online Privacy Protection Act (COPPA) is a regulation that establishes strict rules for you to abide by if the user is a child under the age of 13 years old.
The purpose of COPPA is to protect the personal data and security of children. No matter where you’re located, COPPA applies to your business if you collect the personal information of children in the United States who are under 13 years old.
The regulation prohibits you from collecting personal information about a child if you are a business directed to children or if you knew that you were collecting information from a child.
Collection of data refers to:
- Requesting or encouraging the child to submit personal information
- Enabling children to make personal information publicly available
- Using cookies to track a child online
You must ensure that you provide notice about the information you collect and how you use it. You must also obtain parental consent before collecting and processing any data about a child.
Personal information includes:
- Home address
- Online contact info
- Screen name
- Phone number
- Social security number
- Identifier, IP address, device serial number, customer number in a cookie
- Photo, video, or audio of a child
What Will Replace Tracking Cookies?
A new initiative led by Google called the Privacy Sandbox seeks to replace tracking cookies. It aims to protect users’ personal information by phasing out tracking cookies and blocking covert tracking methods.
However, the initiative also recognizes the necessity of websites to utilize ads to keep their online content free and is in the process of developing alternatives.
The replacement for tracking cookies is still in development, but it will be a technology that is more protective of users’ privacy.
Google has postponed this phase-out of tracking cookies until 2023 to allow for more progress for alternative, privacy-friendly technologies to be further developed.
