The Digital Services Act (DSA) is an EU regulation that creates a safe and accountable online environment. It establishes a unified legal framework for content moderation, platform transparency, and digital advertising across the European Union.
Marketers and SEO practitioners must comply with these rules to manage risk, avoid high fines, and maintain trustworthy interactions with EU users.
What is the Digital Services Act?
The DSA is a comprehensive set of rules for online services, including marketplaces, social media networks, app stores, and search engines. It modernizes the 20-year-old e-Commerce Directive to harmonize how EU member states handle illegal content and user rights.
The law follows a tiered regulatory approach. While basic obligations apply to all digital services, the most stringent requirements are reserved for Very Large Online Platforms (VLOPs) and Very Large Online Search Engines (VLOSEs). These are defined as services with more than [45 million active monthly users in the EU] (Wikipedia).
The regulation [entered into force on 16 November 2022] (Wikipedia). While the largest platforms had to comply earlier, the rules became [fully applicable to all services on 17 February 2024] (AlgorithmWatch).
Why the Digital Services Act matters
The DSA changes how brands and platforms interact with their audiences. Compliance is not optional, as companies risk [fines of up to 6% of their global annual turnover] (Wikipedia) for significant violations.
- Ad transparency: Platforms must clearly label ads and tell users who paid for them and why they are being targeted.
- User control: Users on large platforms must have the option for a non-personalized feed, such as a chronological order, which directly impacts organic reach and SEO strategy.
- Prohibited target groups: The Act introduces a complete ban on showing targeted advertisements to children.
- Sensitive data ban: Profiling users based on sensitive data, such as race, religion, or sexual orientation, is prohibited for advertising purposes.
- UX/UI constraints: Deceptive design tactics, known as "dark patterns" (like misleading consent buttons or aggressive pop-ups), are now illegal.
- Marketplace trust: Marketplaces must verify the contact details of sellers, reducing the risk of fraudulent competition for legitimate businesses.
How the Digital Services Act works
The DSA assigns responsibilities based on the size and impact of the service provider.
Tiered Obligations
- Intermediate services: All providers must follow basic transparency rules and have clear terms of service.
- Hosting services: Must provide a mechanism for users to report illegal content.
- Online platforms: Required to have internal complaint systems and verify third-party sellers. They must also disclose the parameters of their recommender systems.
- VLOPs and VLOSEs: These entities must perform annual systemic risk assessments. They are audited independently to ensure they are mitigating risks like disinformation or threats to public health.
Enforcement
The European Commission directly supervises the largest platforms. For smaller services, each EU country appoints a [Digital Services Coordinator (DSC)] (European Commission) to enforce compliance.
Best practices
- Clarify content moderation: Tell users exactly why their content was removed or their account suspended. Provide a clear path for them to appeal the decision.
- Audit your UX/UI: Remove "dark patterns." Ensure your consent flows and navigation are not deceptive or confusing.
- Standardize seller verification: If you run a marketplace, make "reasonable efforts" to perform random checks on products and trace the identity of your sellers.
- Update ad repositories: Ensure your advertising information is stored and accessible. For VLOPs, this data must stay in a publicly accessible repository.
- Offer feed choices: Provide at least one recommendation system that is not based on user profiling.
Common mistakes
Mistake: Using sensitive personal data for ad targeting. Fix: Review your audience segments to ensure they do not rely on religion, sexual orientation, or race.
Mistake: Obstructing data access for researchers. Fix: Establish a process to grant data access to vetted researchers to analyze systemic risks, as required by Article 40.
Mistake: Delaying responses to "trusted flaggers." Fix: Prioritize notices from certified trusted flaggers to ensure illegal goods or content are handled quickly.
Mistake: Failing to protect minors. Fix: Disable all profiling and targeted advertising for users identified as children.
Examples
X (formerly Twitter)
The Commission issued its first major fine under the DSA to X, totaling [€120 million for deceptive design and ad transparency failures] (Wikipedia). Specifically, the "blue checkmark" system was found to be deceptive because it did not meaningfully verify account holders.
TikTok Lite
In 2024, TikTok agreed to permanent changes to avoid sanctions. The company [withdrew its TikTok Lite rewards feature from the EU] (Wikipedia) after the Commission raised concerns that the "task and reward" system was addictive for minors.
DSA vs DMA
While they were proposed together, these two acts serve different purposes.
| Feature | Digital Services Act (DSA) | Digital Markets Act (DMA) |
|---|---|---|
| Primary Goal | Online safety and fundamental rights. | Fair competition in digital markets. |
| Focus Area | Content moderation and transparency. | Regulating "gatekeeper" platforms. |
| Applies To | All digital intermediary services. | Only large "gatekeeper" companies. |
| Key Metric | Safety and risk mitigation. | Market contestability and fairness. |
FAQ
Who has to comply with the DSA? All online intermediary services that offer their services to users in the EU must comply. This applies regardless of where the company is established. Even if your business is based in the United States, you must follow DSA rules if you have EU-based users.
What happens if I don't comply? The Commission or national coordinators can impose fines of up to 6% of your global annual turnover. They can also apply periodic penalties of up to [5% of your average daily worldwide turnover] (Wikipedia) for every day you delay complying with a remedy.
How does the DSA affect SEO? The requirement for large platforms to offer non-algorithmic feeds (like chronological feeds) may change how users see content. SEO experts must consider that a portion of the audience will opt out of personalized recommendations, making timing and freshness more important.
What are dark patterns in the context of the DSA? Dark patterns are design interfaces that trick users into doing things they didn't intend to do. Examples include making it much harder to cancel a subscription than to sign up, or using confusing language on cookie consent buttons. These are now strictly prohibited.
