The internet has become an integral part of our lives, and we use it for various purposes such as shopping, socializing, and accessing information. However, every time we use a website or app, we leave behind a trail of data that companies can collect, store, and sell. This raises concerns about privacy, data protection, and the potential misuse of personal information. As such, it’s important to understand how websites sell our data and who they sell it to. In this blog post, we’ll delve into the methods used by websites to collect and sell user data. We’ll also explore the different types of buyers who purchase user data and the implications of selling personal information. Additionally, we’ll discuss the role of background check services, which utilize personal data for their services, and provide tips on how to protect your data online. Ultimately, this post aims to increase awareness and encourage readers to take proactive steps to safeguard their personal information.

How websites sell your data

Websites use various methods to collect user data, including tracking cookies, pixels, and device fingerprints. Tracking cookies are small files stored on your device that contain information about your browsing habits, while pixels are small images that track your interactions with a website. Device fingerprints are unique identifiers that websites can use to track your device and monitor your online behavior. Additionally, websites can collect personal information such as your name, address, email, and phone number through forms, surveys, or account registrations.

Data brokers are third-party companies that buy and sell user data. They collect data from websites and other sources, aggregate it, and sell it to other companies for targeted advertising, market research, or other purposes. Data brokers may also create profiles of users based on their interests, behaviors, and demographics, which can be used for more personalized advertising.

Some websites that sell user data include social media platforms, search engines, e-commerce sites, and free online services such as email providers. These websites typically disclose their data collection practices in their privacy policies, although the language used may be difficult to understand. Users may also be required to consent to these practices as a condition of using the service.

Who do they sell it to?

Websites sell user data to various types of buyers, including advertisers, research firms, and government agencies. Advertisers use user data to target their ads more effectively, which can increase the chances of a user clicking on the ad and making a purchase. Research firms may use user data to study consumer behavior and market trends. Government agencies may use user data for law enforcement or national security purposes.

Some companies that buy user data include credit bureaus, insurance companies, and background check services. Credit bureaus use user data to create credit reports and determine creditworthiness, while insurance companies may use it to set rates or investigate claims. Background check services use user data to provide information to employers, landlords, or other entities that need to conduct a background check.

The implications of selling user data are significant. Users may feel that their privacy has been violated, and they may be more vulnerable to scams or other forms of online fraud. Additionally, users may be targeted with advertising that is not relevant to them, which can be annoying or even offensive.

To protect personal data, users can read privacy policies and terms of service agreements before using a website or app, as well as opting out of data collection where possible. Additionally, users can use privacy-focused tools such as ad blockers and virtual private networks (VPNs) to limit data collection and protect their online activity. Finally, it’s important to support data protection laws and regulations that limit the collection and sale of user data.

Background check services

Background check services are third-party companies that collect and analyze public records, criminal histories, and other personal information to provide comprehensive reports on individuals. These reports may include information such as employment history, education, criminal records, and credit history. 

Background check services use personal data for their services, which can include information gathered from websites that sell user data. As such, users should be aware that their data may be used for background checks even if they haven’t directly authorized it. 

Some companies that provide background check services include Intelius, BeenVerified, and Instant Checkmate. It’s important to note that not all background check services are created equal, and users should do their research to find the best background check site for their needs. Factors to consider when choosing a background check site include the types of searches available, the accuracy of the information provided, and the cost of the service.

Users should also be aware that the information provided by background check services may not always be accurate or up-to-date. Mistaken identities, incomplete records, and errors in data entry can all lead to inaccuracies in background check reports. As such, it’s important for users to review their own background check reports and dispute any errors or inaccuracies.

How to protect your data

To protect personal data online, there are several steps that users can take. First, users should read privacy policies and terms of service agreements before using a website or app. This can help users understand how their data will be collected, used, and shared. Additionally, users should opt out of data collection wherever possible, such as by disabling tracking cookies or using privacy-focused browser extensions. 

Users should also be careful when sharing personal information online, such as on social media or in online forums. Information such as names, addresses, and phone numbers can be used to identify individuals and potentially compromise their privacy

It’s also important to support data protection laws and regulations that limit the collection and sale of user data. Users can advocate for stronger privacy protections and support organizations that work to protect privacy rights. 

Finally, users can use privacy-focused tools such as ad blockers and virtual private networks (VPNs) to limit data collection and protect their online activity. Ad blockers can prevent websites from tracking users’ browsing history and displaying targeted ads, while VPNs can encrypt users’ internet traffic and mask their IP addresses, making it more difficult for third parties to track their activity. 


In conclusion, the selling of personal data by websites is a significant concern in today’s digital age. Users should be aware of how their data is being collected, used, and shared, and take steps to protect their privacy online. By reading privacy policies, opting out of data collection, and using privacy-focused tools, users can limit the amount of personal information that is available to third parties.

While the selling of personal data is a complex issue, there are steps that individuals can take to protect their privacy and ensure that their data is used only for its intended purposes. By being proactive and informed, users can enjoy the benefits of the internet while also safeguarding their personal information. It’s important for individuals, companies, and policymakers to work together to create a safer, more transparent digital environment where privacy is protected.
