How to Create PPC Campaigns in Compliance with Data Protection Regulations?


Our goal in this article is to show you how to plan and execute effective PPC campaigns under stricter data protection regulations. Privacy is becoming increasingly important in the world of digital marketing, and it's important for advertisers to stay up-to-date on regulations to avoid penalties and retain the trust of their customers.


Data protection regulations, such as GDPR (General Data Protection Regulation) and CCPA (California Consumer Privacy Act), as well as the elimination of third-party cookies, present new challenges to the digital marketing specialists. In recent years, the protection of consumer data and respect for privacy have become increasingly important, which is also reflected by the tightening of regulations.


The biggest challenge is that while advertisers must comply with data protection regulations, a effectiveness of campaigns must also be maintained. Data protection compliance can often seem complicated and time-consuming, especially when new regulations come into effect. However, the appropriate strategies by using it, it is possible to comply with data protection while optimizing the performance of our campaigns.

Overview of Data Protection Regulations

GDPR and CCPA Basics

In the digital world, data protection is becoming increasingly important, and two key regulations that reflect this are the GDPR and the CCPA.

GDPR (General Data Protection Regulation): The purpose of the regulation introduced by the European Union in 2018 is to strengthen and standardize data protection rights for EU citizens. The GDPR strictly regulates how personal data can be collected, stored and used. All businesses that handle the data of European citizens must comply with this regulation, regardless of where they are based.

CCPA (California Consumer Privacy Act): California's data protection law, which took effect in 2020, has similar goals to GDPR, but is more specific to the US. The CCPA gives California residents rights such as access to their information, request deletion of their information, and prevent the sale of their personal information.

Effects on PPC Campaigns: These regulations strictly limit how we can handle users' data during PPC campaigns. When collecting, storing and using data, we must ensure that all our activities comply with these regulations. For example, we may only collect data that users have consented to, and we must provide them with an opportunity to withdraw that consent at any time.

Removal of Third Party Cookies

Why is this change happening? Third-party cookies are used to increase data protection and user security. Third-party cookies allow advertisers to track users' online activities, often without the users' knowledge. Such practices have increasingly come under criticism as infringing on privacy.

Effects on Advertisers and Users:

  • Advertisers: The elimination of third-party cookies brings significant changes in the field of targeted advertising. Advertisers must find new ways to target and understand user habits. The importance of first-party data increases because it comes directly from users and is data collected with their consent.
  • Users: For users, this change will increase their privacy, as there will be fewer opportunities to track them without their knowledge. However, this may also mean that they will see fewer relevant ads, as it will be harder for advertisers to target them precisely.

Privacy Aspects and PPC Campaigns

User Consent

How can we ensure user consent? One of the basic requirements of data protection regulations is obtaining user consent for the collection and use of data. In order to obtain consent, we must provide users with clear and transparent information about what data we collect, how we use it, and to whom we share it.

  • Pop-ups: The most common method is the use of pop-ups in which users can consent to the collection of data. These pop-ups should be designed to be easy to understand and simple to use.
  • Explicit Consent: In some cases, explicit consent may be required, meaning that users must take an active action (for example, by ticking a box) to consent to data collection.

Opt-in mechanisms and the importance of transparency:

  • Opt-in Mechanisms: Using opt-in mechanisms is key. This means that users must actively consent to the collection of their data, rather than being automatically opted-in.
  • Transparency: Transparency is not only a legal requirement, but also the basis for building trust. We must communicate clearly and comprehensibly with users what data we collect, why we collect it and how we use it.

Data minimization

What is data minimization and why is it important? Data minimization means that we only collect and store as much data as is absolutely necessary to achieve the desired goal. This reduces the risks of handling data and increases the data protection of users.

Practices for reducing the amount of data and handling it securely:

  • Data Selection: We only collect the data that is really necessary to achieve the goals of the campaign. For example, if we want to perform demographic targeting, it may be sufficient to collect only age and gender.
  • Anonymization: During anonymization, the data is modified so that it cannot be traced back to individual users. This increases the level of data protection and reduces risks.
  • Data security: The secure storage and handling of data is of fundamental importance. It must be ensured that only authorized persons have access to the data, and we protect the data against unauthorized access with appropriate technical measures.

First Party Data

Why is first party data important? First-party data is the information that you collect directly from users, such as the data of your website visitors, customers and newsletter subscribers. The importance of first-party data is gaining more and more emphasis with the increase in data protection and user trust. Because this data comes directly from users, it gives advertisers more control and reduces the risk of breaching privacy regulations.

How can we collect and use first-party data effectively?

  • Registration forms and subscriptions: Offer valuable content or discounts in exchange for users' data. It is important that the data collection process is transparent and voluntary.
  • Website analytics: Use it analytical tools that allow you to collect detailed information about visitor behavior and preferences.
  • Customer relations: Build close relationships with customers and ask them directly about their interests and preferences. This is personalized marketing basis may.

Contextual Advertising

What is contextual ad and how does it work? Contextual advertising is a form of targeted advertising that bases the display of ads on the content of the website, rather than on the previous browsing habits of users. This means that the ads will be relevant to what you are viewing content point of view.

Advantages and disadvantages compared to third-party cookies:

  • Advantages:
    • Data protection: Because contextual ads do not track users across multiple websites, they comply with stricter privacy regulations.
    • Relevance: Ads will be relevant to users because they are related to the content they are viewing.
  • Disadvantages:
    • Aiming Accuracy: Contextual ads do not offer the same in-depth targeting capabilities as third-party cookies.
    • Efficiency: Sometimes, contextual ads can be less effective at identifying user intent.

Cohort Based Targeting (FLoC)

THE Google presentation of FLoC technology introduced by: FLoC (Federated Learning of Cohorts) is a technology developed by Google that organizes users into groups (cohorts) based on similar browsing behavior without identifying individuals. This allows us to display targeted ads without accessing users' individual data.

How can it be used in PPC campaigns?

  • Cohort-based targeting: Advertisers can target specific cohorts that are likely to be interested in specific products or services.
  • Data protection: FLoC technology increases privacy by hiding individual user data while enabling targeted advertising.
