Data protection regulations and privacy laws are constantly evolving, and the Digital Markets Act (DMA) brings new considerations to this landscape. Introduced by the European Union, the Digital Markets Act aims to foster a competitive and fair digital market and protect user privacy.


The regulation targets large online platforms, referred to as ‘gatekeepers’, due to their influential role in digital markets. The designated gatekeepers under the DMA are:

  • Alphabet (Google, YouTube, Android)
  • Amazon
  • Apple (iOS, App Store)
  • ByteDance (TikTok)
  • Meta (Facebook, Instagram, WhatsApp)
  • Microsoft (LinkedIn, Windows PC OS)

However, its ripple effects extend to all layers of web development, affecting how developers approach user data, interoperability, and user consent.


We explore how the DMA impacts web development and how web developers can adapt practices for DMA compliance.

Key provisions of the Digital Markets Act impacting web developers

Integrating privacy laws requirements into website and app designs is a significant part of a web developer’s work, directly affecting the handling and protection of user data. The DMA law introduces critical changes for web developers that place greater emphasis on user rights and open competition.

  1. User consent: Strong emphasis on obtaining explicit consent to collect personal data for any purpose, including serving personalized or targeted ads.
  2. Data portability: Users must be able to easily move their data between different platforms, giving them more control over their data and making it simpler for them to switch between services without losing their information.
  3. Interoperability between platforms: Requires gatekeepers’ to make sure their core platform services can work well with other smaller platforms and services, providing other platforms to make their products fit smoothly with the services of these big platforms.

Adapting web development practices for Digital Markets Act compliance


Under privacy laws like the DMA, you must give users clear information about what data is taken, why it’s used, how long it’s kept for, and who might have access to it.


Users must have the choice to say no to giving consent or to take back their consent if they change their mind. They also shouldn’t be tricked or misled about how their data is used.


Ensuring transparency involves two key areas:

  1. Implementing a consent banner that clearly communicates consent choices to users.
  2. Making privacy policies easily accessible and legible.


A transparent consent banner that gives users an actual choice whether or accept or reject consent must have:

  • a clear structure, with visual cues such as contrasting colors to highlight consent options
  • universally recognizable icons for quick understanding
  • interface that is accessible to all users, including those with disabilities.

Privacy policy


Privacy policies are often long and confusing, making it hard for users to understand their rights and the company’s data policies. Legal and compliance teams handle privacy policy writing, but web development teams can help make them user-friendly.


A website’s footer is a common place to include a link to a privacy policy that most users will know, making it easy to find. You can also make the privacy policy easy to digest in how you present it.


Let’s look at some privacy policies with a user-friendly presentation.

  • Airbnb uses one landing page that links out to the different privacy policies for various regions. There are also direct links to other important documents such as the cookies policy and terms for enterprise customers.
  • Slack uses a table of contents that links to each separate section of the privacy policy for users to jump to. It also includes external links to information about Data Protection Authorities in the EU and UK for people to contact if they have complaints.
  • Uber uses lots of bullet points and lists, making it scannable and easy to read.
  • Facebook uses a menu in the sidebar so visitors can go to a new section without scrolling up and down. There is also a link to a printable version of the cookies policy, as well as a link to previous versions for users to see the changes.
  • Usercentrics uses an accordion menu for each section, making it easy for users to find the section they’re looking for and collapse sections they aren’t reading so they can focus on the one that’s expanded.

Potential challenges in ensuring transparent access


While providing users with transparent access poses challenges, the right tools and collaborations can help you tackle these complexities, enhance the user experience, and obtain legally valid consent.

  1. Dynamic nature of data practices: Web developers must regularly update transparency features to reflect changes in the company’s data practices and maintain compliance with data protection regulations, without disrupting the user experience. Collaborate with legal and compliance teams to help keep the website up to date with changes.
  2. Complexity of consent management: Developing a consent management system that enables users to easily understand and manage their preferences and the website owner to compliantly record consent can be technically challenging. Use a consent management platform (CMP) to save time and effort by streamlining consent management and enabling compliance.
  3. Clear presentation: Designing information to be clear and accessible can be challenging when dealing with diverse user groups who have varying levels of technical understanding. Work with user research and design teams to ensure the information caters to all users, enhancing clarity and accessibility regardless of their technical background.

Internationalization and localization: Adapting transparency features to different languages and cultures while maintaining accuracy and legal compliance is challenging, especially for global brands. Use a CMP that offers multiple language options and can help obtain valid consent from users in diverse regions globally.

For data portability


The DMA requires gatekeepers to enable users to move their data easily from one service to another, empowering them with control over their data and freedom to switch services without losing their information.


Even if a company is not a gatekeeper and therefore not directly under the DMA’s scope, it still needs to be prepared to honor data portability requests if it uses a core platform service that is required to offer this feature under the DMA.

To create a user-friendly data portability experience, you can consider:

  1. User interface design: Incorporate the data export option within the user account settings to make it easily accessible and user-friendly.
  2. Data format selection: Offer multiple data export formats that are commonly used and can be easily processed, such as CSV, JSON, and XML.
  3. User notification system: Set up notifications to inform users when their data export is ready for download, such as automated emails or in-app notifications.
  4. Timeframe and feedback: Clearly communicate the expected timeframe for data export processing. After the export, provide a way for users to give feedback, helping to continually improve this feature.
  5. Document process: Create step-by-step instructions to help users understand where to find the data export option and how to download their data.

A good example of documentation is from Qualtrics, which has detailed guides for downloading survey response data. While the use case differs from downloading user data, the principles apply to data portability download requests too.


Qualtrics’ documentation includes detailed instructions, screenshots, and FAQs for users across different pages on related topics:

For interoperability


The DMA requires gatekeepers to ensure the core platform services can work together with other platforms, enabling different services and platforms to communicate and share data effectively, fostering a more connected digital environment.


This requirement offers a massive opportunity for smaller businesses to build web services that integrate easily with these large platforms. With interoperability, smaller platforms can reach more people, tap into larger markets, and create new services that work well with other platforms, improving how users experience these digital services.


The Global Partnership for Sustainable Development Data has released a playbook with checklists and key questions to consider that can serve as valuable guidance for you.


This playbook offers specific steps and considerations for building web services that integrate easily with the global developer community, enhancing interoperability. It covers a range of concerns from developing good documentation to building user trust.

The role of web development and digital agencies in ensuring DMA compliance

The DMA’s aim is to develop fair market conditions where businesses of all sizes can compete. This gives smaller web development firms and digital agencies a chance to provide services and solutions to help companies meet DMA requirements.


Key areas of focus include:

  1. Developing compliant solutions: Agencies can build web solutions that adhere to DMA guidelines, ensuring features like data portability, interoperability, and transparency are integrated into web designs and functionalities.
  2. Advisory services: Offering consultancy services to clients on how to align their technologies with DMA regulations and help them understand and implement necessary changes.
  3. User consent management: Managing consent platforms is vital in obtaining proper user consent for data collection and processing. Agencies can implement and oversee these systems to ensure consent meets DMA requirements.
  4. Building trust with compliance: By demonstrating compliance with the DMA, agencies help their clients build trust with users. This approach enhances the reputation and confidence of both the agency and its clients.

Innovative solutions for compliance challenges: Leveraging technology and forming collaborations or partnerships can be an effective way to address complex compliance challenges and help clients stay ahead in a competitive and regulatory landscape.
