Best Practices for Balancing Ad Personalisation and User Privacy


Key Takeaways


  • Privacy concerns are increasingly important to users, and brands that prioritise transparency and user control over data are more likely to earn trust and loyalty.
  • Balancing ad personalisation with user privacy requires a strategic approach that involves careful consideration of data collection and use and ongoing monitoring and adjustments to ensure compliance with changing regulations and user preferences.
  • Implementing the best privacy and ad personalisation practices, such as offering clear opt-in and opt-out options, can help brands build trust with users while delivering effective and relevant advertising.

Personalised advertising has gained significant traction in the digital landscape, with companies leveraging data to create tailored consumer experiences. According to studies in 2020, 63% of consumers expected personalised experiences, and 80% of consumers were more likely to purchase when brands offer personalised recommendations. 

However, over the years, as the amount of personal information companies collected for targeted advertising increased, so did privacy and data security concerns. How can companies balance delivering personalised ads and respecting user privacy? This blog will explore the best practices organisations can employ to obtain user data ethically and use them to create targeted and personalised ads.


Understanding Personalised Ads and User Privacy Concerns


By leveraging data on users’ browsing history, search queries, location, and demographic information, companies can deliver highly relevant and targeted ads that are more likely to capture users’ attention and drive engagement.


For instance, Amazon’s recommendation engine suggests products based on users’ browsing and purchase history, while social media platforms like Facebook and Instagram show ads based on users’ interests, behaviours, and connections. This allows advertisers to provide users with more relevant and engaging ads, increasing their likelihood of purchasing or taking the desired action.


So why are users concerned about sharing personal information online?


With the increasing awareness and regulations around data privacy, users have become more concerned about how their personal information is collected, used, and shared. 87% of consumers are concerned about their data privacy, and 91% believe that companies should be more transparent about how their data is used.

This heightened awareness and regulatory landscape have increased concerns among users about the potential misuse of their data. Users worry about their data being exploited for targeted ads without explicit consent or knowledge. For example, in 2018, then Facebook faced a major scandal when it was revealed that the data of millions of users were harvested by a third-party app without their consent and used for political advertising.


Balancing Personalised Ads and User Privacy Concerns


  1. Obtaining User Consent: One of the key best practices for businesses is to ensure that they obtain explicit consent from users before collecting and using their data for personalised ads. This can be achieved through clear and transparent consent mechanisms, such as opt-in forms or cookie banners, that provide users with a choice to opt-in or opt-out of data collection and personalised ads.
    • Best practices:
      • Clearly explain how data will be used: It’s important for businesses to provide clear and concise explanations of how user data will be used for personalised ads. This should include information on the types of data collected, the purposes for which the data will be used, and any third parties who may have access to the data. By providing this information upfront, users can make informed decisions about whether or not they want to opt-in to data collection.
      • Follow applicable laws and regulations: Businesses must ensure that they comply with applicable data privacy laws and regulations, such as the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA). These laws provide guidelines on how businesses should collect, store, and use user data, as well as requirements for obtaining user consent. Failure to comply with these laws can result in significant financial penalties and damage a company’s reputation.
      • Provide users with options to revoke consent: It’s important for businesses to give users the option to revoke their consent at any time. This can be achieved through clear and easy-to-use opt-out mechanisms that allow users to withdraw their consent and stop data collection. By respecting user preferences and choices, businesses can demonstrate their commitment to user privacy and build trust.
  2. Transparent Data Collection: Businesses should be transparent about their data collection practices and provide users with clear information about the types of data being collected, how it will be used, and the benefits of personalised ads. This transparency helps build trust with users and fosters a positive relationship between businesses and their customers.
    • Best practices:
      • Clearly communicate purpose and benefits: It’s important for businesses to communicate the purpose and benefits of personalised ads to their users. By explaining how personalised ads can improve relevance and create a better user experience, businesses can help users understand the value of their data and feel more comfortable with data collection.
      • Use plain language: When communicating with users about data privacy, it’s important to avoid complex legal jargon in privacy policies and consent forms. Instead, businesses should use plain language that is easy for users to understand. This can help to build trust and increase transparency in data collection practices.
      • Provide user control: Providing users with options to control and manage their data is crucial to any personalised ad strategy. This can include allowing users to update their preferences, delete their data, or opt out of personalised ads. By giving users control over their data, businesses can demonstrate their commitment to user privacy and build trust.
  3. Maintaining Data Security: Businesses should prioritise data security to protect users’ personal information from unauthorised access, use, or disclosure. This includes implementing robust security measures, such as encryption, access controls, and regular data audits, to safeguard user data from potential breaches.
    • Best practices:
      • Follow industry best practices and standards: Businesses should follow industry best practices and standards for data security, such as ISO 27001, NIST Cybersecurity Framework, and PCI-DSS. These standards provide guidelines for data security management, including risk assessment, data protection, incident management, and security monitoring. By adhering to these standards, businesses can ensure that they are implementing best practices for data security.
      • Regularly assess and monitor data security processes: Regular assessments and monitoring of data security processes are essential to identifying and addressing vulnerabilities. Businesses should conduct regular security audits, penetration testing, and vulnerability scans to identify weaknesses in their data security systems. This allows businesses to mitigate risks and prevent security breaches proactively.
      • Educate employees and contractors: Educating employees and contractors about data security best practices is critical for maintaining the security of user data. Businesses should provide training and awareness programs to all employees and contractors who handle user data. This training should cover data handling and protection, password security, phishing and social engineering awareness, and incident reporting. By educating employees and contractors, businesses can reduce the risk of human error or negligence leading to security breaches.


Examples of Businesses Successfully Balancing Personalised Ads with User Privacy Concerns:



Apple, a global technology company, has taken a proactive approach to managing privacy challenges in personalised advertising. They have implemented stringent data security measures, such as encryption and regular data audits, to protect user data. They also prioritise transparency by clearly communicating their data collection practices and giving users control over their data preferences. Through these efforts, Apple has maintained a high level of trust among users, resulting in a 15% increase in customer loyalty and repeat purchases.


Amazon, a leading e-commerce retailer, has implemented a data-driven approach to personalised ads while prioritising user privacy. They obtain explicit consent from users through clear opt-in mechanisms and provide transparent information about their data collection practices. They also allow users to easily manage their data preferences, including opting out of personalised ads. As a result, Amazon has seen a 25% increase in click-through rates and a 20% increase in conversion rates, indicating that their personalised ads are effectively engaging users without compromising their privacy.




The increasing awareness and regulations around data privacy have brought to light the challenges of balancing personalised ads with user privacy concerns. While personalised ads has its own advantages, businesses need to adopt responsible and ethical practices to ensure privacy is maintained. 

The call for user privacy is strong, and businesses must prioritise it to build trust, maintain customer loyalty, and drive long-term success in the digital advertising landscape. By adopting responsible and ethical practices, businesses can strike the right balance between personalised ads and user privacy concerns, ultimately driving success in their advertising efforts.
