Digital Markets Act FAQ: Top 30 Questions Answered for Website Compliance

Introduction

The Digital Markets Act (DMA) is reshaping how gatekeeper platforms handle user data, and its ripple effects are hitting website owners hard. If you run a site that uses Google Analytics, embeds YouTube videos, or relies on any gatekeeper service, you need to understand how the DMA intersects with GDPR consent requirements. This practical guide answers the top 30 questions about the DMA for website compliance, focusing on what you can verify today with a scanner like GDPRChecker. We’ll cover consent mode gaps, cookie banner pitfalls, and how to close compliance gaps step by step—without legal jargon.

What Is the Digital Markets Act and Why It Matters for Website Owners

The Digital Markets Act (DMA) is an EU regulation that targets large online platforms designated as “gatekeepers” (e.g., Google, Meta, Amazon). Its goal is to ensure fair and open digital markets. For website owners, the DMA’s most immediate impact is on data processing by gatekeeper services you use. Under the DMA, gatekeepers must obtain explicit user consent before combining personal data across their core platform services. This means if you use Google Analytics and Google Ads, Google now needs consent for data sharing between these services—and that consent must flow from your website’s consent banner.

Practically, this forces you to implement robust consent mechanisms. If a visitor rejects cookies, gatekeeper tags must respect that choice. The DMA doesn’t replace GDPR; it adds another layer of consent requirements specifically for gatekeeper data processing. For you, this means your consent management platform (CMP) must signal consent status to gatekeeper tags, and you must be able to prove it works. GDPRChecker’s scanner helps you verify that pre-consent network requests are blocked, consent banners behave correctly, and disclosures are complete—all essential for DMA compliance.

How the DMA Changes Consent Requirements for Gatekeeper Services

Under the DMA, gatekeepers can no longer rely on legitimate interest for combining data across services. They must obtain “freely given, specific, informed and unambiguous” consent—mirroring GDPR’s high bar. For your website, this translates into two critical technical requirements:

1. **Consent signals must be sent to gatekeeper tags before they fire.** Google’s Consent Mode v2 is the primary mechanism for this. It allows tags to adjust their behavior based on consent state. Without it, Google tags may still collect data even when consent is denied, creating a compliance gap.
2. **The consent banner must offer a genuine reject option.** A banner with only an “Accept All” button and no easy way to refuse is non-compliant. The DMA reinforces this because gatekeepers need a clear “no” signal to stop data combination.

GDPRChecker scans your site to detect whether tags fire before consent. It checks for pre-consent network requests to gatekeeper domains (like `google-analytics.com` or `doubleclick.net`) and flags them. This is your first line of defense: if the scanner finds such requests, your DMA compliance is at risk.

Real-World Example: Google Analytics and Consent Mode

Imagine you run an e-commerce site using Google Analytics 4 (GA4) and Google Ads. A visitor lands on your site and clicks “Reject All” in your cookie banner. With Consent Mode v2 implemented correctly, GA4 sends a cookieless ping to Google, but no advertising cookies are set, and data is not used for remarketing. Without Consent Mode, GA4 might still set cookies and send full data, violating both GDPR and DMA. GDPRChecker’s scanner can simulate this reject flow and confirm that no advertising cookies are dropped.

Step-by-Step Implementation: Closing the DMA Compliance Gaps

Closing DMA-related gaps requires a systematic approach. Here’s how to implement the necessary changes, verified with GDPRChecker at each step.

1. Close the Consent Mode Gap

Google Consent Mode v2 is essential for any site using Google services. It introduces two new consent signals: `ad_user_data` and `ad_personalization`. These must be set based on user consent before Google tags load.

• **Action:** Update your CMP to support Consent Mode v2. If you use Google Tag Manager (GTM), configure consent initialization triggers to fire before any other tags.
• **Verification:** Run a GDPRChecker scan with the scanner set to “reject all” mode. Check the report for any Google network requests that occur before consent. If you see hits to `google-analytics.com` or `googletagmanager.com` before the consent update, your implementation is flawed.

2. Close the Google CMP Gap

While GDPRChecker is not a Google Certified CMP, it helps you verify that your chosen CMP works correctly. A common mistake is using a CMP that doesn’t properly signal consent to Google tags, leaving a gap.

• **Action:** Ensure your CMP is configured to pass consent states to Google via the Consent Mode API. Test with Google’s Tag Assistant to confirm signals are sent.
• **Verification:** GDPRChecker’s scanner checks for the presence of consent mode defaults in the page source. It also verifies that tags respect the consent state. If you see tags firing with `gcs=G100` (no consent) but still setting cookies, there’s a gap.

3. Close the Cookie Banner Gap

Your cookie banner must provide a clear “Reject All” option that is as prominent as “Accept All.” It must not use manipulative design (dark patterns) to nudge users toward acceptance.

• **Action:** Redesign your banner to have two equally weighted buttons. Ensure that rejecting is a single click, not buried in settings.
• **Verification:** Use GDPRChecker’s visual banner check to confirm the banner appears on first visit and that the reject button works. The scanner can also verify that no non-essential cookies are set after rejection.

4. Close the Privacy Policy Gap

Your privacy policy must disclose the use of gatekeeper services and how data is shared between them. Under the DMA, you must name the gatekeepers and explain the purposes of data combination.

• **Action:** Update your privacy policy to list all gatekeeper services (e.g., Google Analytics, Google Ads, YouTube) and state that data may be combined only with consent.
• **Verification:** GDPRChecker’s policy link checker ensures your privacy policy is accessible from every page and contains required disclosures. It can flag missing gatekeeper mentions.

5. Close the Cookie Scanner Gap

Regular scanning is crucial because websites change frequently. New tags, plugins, or marketing pixels can introduce compliance gaps overnight.

• **Action:** Schedule weekly GDPRChecker scans. Review the cookie inventory report for new or unknown cookies, especially those from gatekeeper domains.
• **Verification:** The scanner categorizes cookies and trackers, showing which ones are set before consent. Pay special attention to any marked “pre-consent” from gatekeeper domains.

Common Mistakes and How to Avoid Them

Even well-intentioned site owners make mistakes that undermine DMA compliance. Here are the most frequent ones and how to avoid them.

Mistake 1: Assuming Consent Mode Is Optional

Some site owners think Consent Mode is only for advanced users. In reality, if you use any Google service that processes personal data, Consent Mode v2 is mandatory for DMA compliance. Without it, Google may combine data across services without a legal basis.

**Avoidance:** Implement Consent Mode v2 even if you only use GA4. GDPRChecker’s scanner will flag missing consent mode defaults in the page source.

Mistake 2: Ignoring Pre-Consent Network Requests

A tag might be configured to fire on page load, before the consent banner even appears. This sends data to gatekeepers without consent.

**Avoidance:** Use GDPRChecker’s pre-consent request check. It lists all network requests that occur before user interaction with the banner. Block any gatekeeper requests at this stage.

Mistake 3: Incomplete Reject Flow

Your banner might have a reject button, but clicking it doesn’t actually block all gatekeeper tags. Some tags might ignore the consent signal due to misconfiguration.

**Avoidance:** After implementing the reject flow, run a GDPRChecker scan in “reject all” mode. Verify that no gatekeeper cookies are set and that tags fire in consent mode only.

Mistake 4: Neglecting Embedded Gatekeeper Content

If you embed YouTube videos or Google Maps, these can set cookies even if the user doesn’t interact with them. Under the DMA, you need consent before loading such embeds.

**Avoidance:** Use a two-click solution: replace embeds with a placeholder that requires user click to load. GDPRChecker can detect if embedded gatekeeper content loads automatically.

How to Validate DMA Compliance with GDPRChecker

GDPRChecker provides a practical, scanner-based approach to validate your DMA compliance posture. Here’s a step-by-step validation workflow:

1. **Initial Scan:** Run a full site scan with default settings. Review the summary for critical issues like pre-consent requests and missing consent mode.
2. **Reject Flow Test:** Configure the scanner to simulate a user who rejects all cookies. Check that no gatekeeper cookies are set and that tags fire in consent mode.
3. **Banner Behavior Check:** Use the visual banner test to ensure the banner appears correctly on desktop and mobile, and that the reject option works.
4. **Policy Link Verification:** Confirm that your privacy policy is linked from every page and contains gatekeeper disclosures.
5. **Ongoing Monitoring:** Set up scheduled scans to catch new compliance gaps as your site evolves.

For advanced needs, GDPRChecker’s paid plans offer managed consent banner, runtime protection, and consent records—all of which provide evidence of compliance for supervisory authorities.

Comparison: DMA vs. GDPR Consent Requirements

While both regulations require consent, they apply to different entities and have distinct scopes. The table below highlights key differences.

| Aspect | GDPR | DMA | |--------|------|-----| | **Who is regulated?** | All data controllers and processors | Designated gatekeeper platforms | | **Consent scope** | Any processing of personal data | Combining data across core platform services | | **Consent basis** | Consent or legitimate interest (in some cases) | Only explicit consent for data combination | | **Technical implementation** | CMP and cookie banner | Consent Mode v2 for Google services | | **Enforcement** | Data protection authorities | European Commission and national authorities |

For website owners, the practical takeaway is that DMA compliance is an extension of GDPR compliance, with a specific focus on gatekeeper services. If you’ve already implemented robust GDPR consent, you’re partway there—but you must add Consent Mode v2 and verify it works.

Real-World Examples of DMA Compliance Gaps

Example 1: The Missing Consent Mode Default

A news website uses Google Ad Manager and GA4. Their CMP is configured to fire tags only after consent, but they forgot to set consent mode defaults. When a user rejects cookies, GA4 still sends full data because it defaults to `granted`. GDPRChecker’s scan reveals the missing defaults, and the site owner adds them via GTM.

Example 2: Pre-Consent YouTube Embed

A blog embeds a YouTube video that loads automatically. Even if the user rejects cookies, the embed sets a cookie from `youtube.com`. GDPRChecker flags this as a pre-consent request. The owner implements a click-to-load placeholder, and the next scan shows no pre-consent gatekeeper requests.

Example 3: Incomplete Reject Flow

An e-commerce site has a reject button, but it only blocks analytics cookies, not marketing cookies. A GDPRChecker reject-flow scan shows that Facebook Pixel and Google Ads cookies are still set. The owner updates the CMP configuration to block all non-essential cookies on reject, and a rescan confirms the fix.
